Abstract
Dehydroepiandrosterone (DHEA) is frequently integrated as an adjuvant in over a quarter of controlled ovarian hyperstimulation (COH) protocols, despite the ongoing debate regarding its impact. This study aimed to evaluate the efficacy and mechanism of action of DHEA on ovarian follicular development and ovarian response in rats with varying ovarian reserves. The study involved 75 rats categorized into 15 distinct groups. The ovarian tissues of rats in both the normal ovarian reserve group and the premature ovarian insufficiency (POI) group, induced by 4-vinylcyclohexene diepoxide (VCD) injection, were subjected to histomorphological and biochemical analyses following the administration of DHEA, either alone or in combination with COH. Follicle counting was performed on histological sections obtained from various tissues. Serum concentrations of anti-Müllerian hormone (AMH) and the quantification of specific proteins in ovarian tissue, including phosphatase and tensin homolog of chromosome 10 (PTEN), phosphoinositide 3-kinase (PI3K), phosphorylated protein kinase B (pAKT), cyclooxygenase 2 (COX-2), caspase-3, as well as assessments of total antioxidant status and total oxidant status, were conducted employing the ELISA method. The impact of DHEA exhibited variability based on ovarian reserve. In the POI model, DHEA augmented follicular development and ovarian response to the COH protocol by upregulating the PTEN/PI3K/AKT signaling pathway, mitigating apoptosis, inflammation, and oxidative stress, contrary to its effects in the normal ovarian reserve group. In conclusion, it has been determined that DHEA may exert beneficial effects on ovarian stimulation response by enhancing the initiation of primordial follicles and supporting antral follicle populations.

Abstract
BACKGROUND Practitioners in the field of assisted reproductive technology (ART) continually seek alternative or adjunct treatments to improve ART outcomes. This Cochrane review investigates the adjunct use of synthetic versions of two naturally produced hormones, dehydroepiandrosterone (DHEA) and testosterone (T), in assisted reproduction. Steroid hormones are proposed to increase conception rates by positively affecting follicular response to gonadotrophin stimulation. This may lead to a greater oocyte yield and, subsequently, an increased chance of pregnancy. OBJECTIVES To assess the effectiveness and safety of DHEA and T as pre- or co-treatments in infertile women undergoing assisted reproduction. SEARCH METHODS We searched the following electronic databases up to 8 January 2024: the Gynaecology and Fertility Group (CGF) Specialised Register, CENTRAL, MEDLINE, Embase, PsycINFO, and trial registries for ongoing trials. We also searched citation indexes, Web of Science, PubMed, and OpenGrey. We searched the reference lists of relevant studies and contacted experts in the field for any additional trials. There were no language restrictions. SELECTION CRITERIA Randomised controlled trials (RCTs) comparing DHEA or T as an adjunct treatment to any other active intervention, placebo, or no treatment in women undergoing assisted reproduction. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted relevant data, and assessed risk of bias. We pooled data from studies using fixed-effect models. We calculated odds ratios (ORs) for each dichotomous outcome. Analyses were stratified by type of treatment. We assessed the certainty of evidence for the main findings using GRADE methods. MAIN RESULTS We included 29 RCTs. There were 1599 women in the intervention group and 1469 in the control group. Apart from three trials, the trial participants were women identified as 'poor responders' to standard in vitro fertilisation (IVF) protocols. The included trials compared either T or DHEA treatment with placebo or no treatment. Pre-treatment with DHEA versus placebo/no treatment: DHEA likely results in little to no difference in live birth/ongoing pregnancy rates (OR 1.30, 95% confidence interval (CI) 0.95 to 1.76; I² = 16%, 9 RCTs, N = 1433, moderate certainty evidence). This suggests that in women with a 12% chance of live birth/ongoing pregnancy with placebo or no treatment, the live birth/ongoing pregnancy rate in women using DHEA will be between 12% and 20%. DHEA likely does not decrease miscarriage rates (OR 0.85, 95% CI 0.53 to 1.37; I² = 0%, 10 RCTs, N =1601, moderate certainty evidence). DHEA likely results in little to no difference in clinical pregnancy rates (OR 1.18, 95% CI 0.93 to 1.49; I² = 0%, 13 RCTs, N = 1886, moderate certainty evidence). This suggests that in women with a 17% chance of clinical pregnancy with placebo or no treatment, the clinical pregnancy rate in women using DHEA will be between 16% and 24%. We are very uncertain about the effect of DHEA on multiple pregnancy (OR 3.05, 95% CI 0.47 to 19.66; 7 RCTs, N = 463, very low certainty evidence). Pre-treatment with T versus placebo/no treatment: T likely improves live birth rates (OR 2.53, 95% CI 1.61 to 3.99; I² = 0%, 8 RCTs, N = 716, moderate certainty evidence). This suggests that in women with a 10% chance of live birth with placebo or no treatment, the live birth rate in women using T will be between 15% and 30%. T likely does not decrease miscarriage rates (OR 1.63, 95% CI 0.76 to 3.51; I² = 0%, 9 RCTs, N = 755, moderate certainty evidence). T likely increases clinical pregnancy rates (OR 2.17, 95% CI 1.54 to 3.06; I² = 0%, 13 RCTs, N = 1152, moderate certainty evidence). This suggests that in women with a 12% chance of clinical pregnancy with placebo or no treatment, the clinical pregnancy rate in women using T will be between 17% and 29%. We are very uncertain about the effect of T on multiple pregnancy (OR 2.56, 95% CI 0.59 to 11.20; 5 RCTs, N = 449, very low certainty evidence). We are uncertain about the effect of T versus oestradiol or T versus oestradiol + oral contraceptive pills. The certainty of the evidence was moderate to very low, the main limitations being lack of blinding in the included trials, inadequate reporting of study methods, and low event and sample sizes in the trials. Data on adverse events were sparse; any reported events were minor. AUTHORS' CONCLUSIONS Pre-treatment with T likely improves, and pre-treatment with DHEA likely results in little to no difference, in live birth and clinical pregnancy rates in women undergoing IVF who have been identified as poor responders. DHEA and T probably do not decrease miscarriage rates in women under IVF treatment. The effects of DHEA and T on multiple pregnancy are uncertain. Data regarding adverse events were very limited; any reported events were minor. Research is needed to identify the optimal duration of treatment with T. Future studies should include data collection on adverse events and multiple pregnancy.

Abstract
BACKGROUND Evaluating the efficacy of letrozole overlapped with gonadotropin-modified letrozole protocol (mLP) for diminished ovarian reserve (DOR) or advanced-age women with repeated cycles. METHODS This is a retrospectively registered, paired-match study including 243 women with DOR and 249 women aged over 40 years old who received in vitro fertilization (IVF) treatment. 123 women received stimulation with mLP (mLP group). GnRH agonist (GnRH-a) long, GnRH antagonist (GnRH-anta), and mild stimulation protocol were used as controls with 123 women in each group. We further analyzed 50 of 123 patients in the mLP group who have experienced more than one failed cycles with other ovarian stimulation protocols (non-mLP group). Clinical pregnancy rate (CPR), cumulative clinical pregnancy rate (CCPR), and live birth rate (LBR) were main outcomes. RESULTS The CPR in the mLP group (38.46%) was significantly higher than mild stimulation (17.11%), but not significantly different from GnRH-a long (26.13%) and GnRH-anta (29.17%) group. The CCPR showed an increasing trend in the mLP group (33.33%) although without significance when compared with controls. The CCRP of GnRH-a long, GnRH-anta, mild stimulation group were 21.68%, 29.03%, and 13.04%, respectively. In women with repeated cycles, mLP achieved the higher available embryo rate (P < 0.05), the top-quality embryo rate, the CPR (P < 0.001), and the LBR (P < 0.001). Further study showed a positive correlation between testosterone and the number of oocytes retrieved in the mLP group (r = 0.395, P < 0.01). CONCLUSION The mLP may be effective for aged or DOR women who have experienced previous cycle failure by improving the quality of embryos, the CPR, and the LBR. An increasing serum testosterone level may reflect follicular growth during ovarian stimulation.

Abstract
BACKGROUND Assisted reproductive technology (ART) has brought good news to infertile patients, but how to improve the pregnancy outcome of poor ovarian response (POR) patients is still a serious challenge and the scientific evidence of some adjuvant therapies remains controversial. AIM Based on previous evidence, the purpose of this systematic review and network meta-analysis was to evaluate the effects of DHEA, CoQ10, GH and TEAS on pregnancy outcomes in POR patients undergoing in vitro fertilization and embryo transplantation (IVF-ET). In addition, we aimed to determine the current optimal adjuvant treatment strategies for POR. METHODS PubMed, Embase, The Cochrane Library and four databases in China (CNKI, Wanfang, VIP, SinoMed) were systematically searched up to July 30, 2022, with no restrictions on language. We included randomized controlled trials (RCTs) of adjuvant treatment strategies (DHEA, CoQ10, GH and TEAS) before IVF-ET to improve pregnancy outcomes in POR patients, while the control group received a controlled ovarian stimulation (COS) regimen only. This study was reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The surface under the cumulative ranking curve (SUCRA) was used to provide a pooled measure of cumulative ranking for each outcome. RESULTS Sixteen RCTs (2323 women) with POR defined using the Bologna criteria were included in the network meta-analysis. Compared with the control group, CoQ10 (OR 2.22, 95% CI: 1.05 to 4.71) and DHEA (OR 1.92, 95% CI: 1.16 to 3.16) had obvious advantages in improving the clinical pregnancy rate. CoQ10 was the best in improving the live birth rate (OR 2.36, 95% CI: 1.07 to 5.38). DHEA increased the embryo implantation rate (OR 2.80, 95%CI: 1.41 to 5.57) and the high-quality embryo rate (OR 2.01, 95% CI: 1.07 to 3.78) and number of oocytes retrieved (WMD 1.63, 95% CI: 0.34 to 2.92) showed a greater advantage, with GH in second place. Several adjuvant treatment strategies had no significant effect on reducing the cycle canceling rate compared with the control group. TEAS was the least effective of the four adjuvant treatments in most pooled results, but the overall effect appeared to be better than that of the control group. CONCLUSION Compared with COS regimen, the adjuvant use of CoQ10, DHEA and GH before IVF may have a better clinical effect on the pregnancy outcome of POR patients. TEAS needs careful consideration in improving the clinical pregnancy rate. Future large-scale RCTs with direct comparisons are needed to validate or update this conclusion.

Higher live birth rate following transdermal testosterone pretreatment in poor responders: a systematic review and meta-analysis. Reprod Biomed Online 2023; 46:81-91.

Abstract
A systematic review and meta-analysis was performed aiming to identify good-quality randomized controlled trials (RCT) evaluating testosterone pretreatment in poor responders. Eight RCTs were analysed, evaluating 797 women. Transdermal testosterone gel was used in all studies, with a dose ranging from 10 to 12.5 mg/day for 10-56 days. The main outcome measure was achievement of pregnancy, expressed as clinical pregnancy or live birth. Testosterone pretreatment was associated with a significantly higher live birth (risk ratio [RR] 2.07, 95% confidence interval [CI] 1.09-3.92) and clinical pregnancy rate (RR 2.25, 95% CI 1.54-3.30), as well as a significant increase in the number of cumulus-oocyte complexes retrieved. Significantly fewer days to complete ovarian stimulation, a lower total dose of gonadotrophins, a lower cancellation rate due to poor ovarian response and a thicker endometrium on the day of triggering of final oocyte maturation were observed. No significant differences were observed in oestradiol concentration, the numbers of follicles ≥17 mm, metaphase II oocytes, two-pronuclear oocytes and embryos transferred, and the proportion of patients with embryo transfer. The current study suggests that the probability of pregnancy is increased in poor responders pretreated with transdermal testosterone who are undergoing ovarian stimulation for IVF.

Abstract
Reproductive aging is characterized by a decline in oocyte quantity and quality, which is directly associated with a decline in reproductive potential, as well as poorer reproductive success and obstetrical outcomes. As women delay childbearing, understanding the mechanisms of ovarian aging and follicular depletion have become increasingly more relevant. Age-related meiotic errors in oocytes are well established. In addition, it is also important to understand how intraovarian regulators change with aging and how certain treatments can mitigate the impact of aging. Individual studies have demonstrated that reproductive pathways involving antimullerian hormone (AMH), vascular endothelial growth factor (VEGF), neurotropins, insulin-like growth factor 1 (IGF1), and mitochondrial function are pivotal for healthy oocyte and cumulus cell development and are altered with increasing age. We provide a comprehensive review of these individual studies and explain how these factors change in oocytes, cumulus cells, and follicular fluid. We also summarize how modifiers of folliculogenesis, such as vitamin D, coenzyme Q, and dehydroepiandrosterone (DHEA) may be used to potentially overcome age-related changes and enhance fertility outcomes of aged follicles, as evidenced by human and rodent studies.

Abstract
Controlled ovarian stimulation has been an integral part of in vitro fertilisation (IVF) treatment cycles. Availability of different gonadotropins for ovarian stimulation and gonadotropin releasing hormone (GnRH) analogues for prevention of premature rise of leutinising hormone during follicular phase offer an opportunity to utilise them for a successful outcome in women with different subsets of ovarian response. Further, use of GnRH agonist as an alternative for human chorionic gonadotropin improves safety of ovarian stimulation in hyper-responders. Mild ovarian stimulation protocols have emerged as an alternative to conventional protocols in the recent years. Individualisation plays an important role in improving safety of IVF in hyper-responders while efforts continue to improve efficacy in poor responders. Some of the follicular and peri-ovulatory phase interventions may be associated with negative impact on the luteal phase and segmentalisation of the treatment with frozen embryo transfer may be an effective strategy in such a clinical scenario. This narrative review looks at the available evidence on various aspects of ovarian stimulation strategies and their consequences. In addition, it provides a concise summary of the evidence that has emerged from India on various aspects of ovarian stimulation.

Abstract
Dehydroepiandrosterone (DHEA) is an androgen synthesized by the adrenal cortex, which is an intermediary in the biosynthesis of sex hormones, such as testosterone and estradiol. DHEA mostly circulates as a conjugated ester, in the form of sulfate (DHEA-S). There exist several endogenous factors able to influence its synthesis, the most common ones being the corticotrophin-releasing hormone (CRH), adrenocorticotrophin (ACTH), growth factors, and proinflammatory cytokines, among others. Like other steroid hormones, DHEA, can alter the functioning of immune cells and therefore the course of diseases exhibiting an immune-inflammatory component, mostly from autoimmune or infectious nature. We herein review the role played by DHEA during a major infectious disease like tuberculosis (TB). Data recorded from TB patients, mouse models, or in vitro studies show that DHEA is likely to be implied in better disease control. This provides a stimulating background for carrying out clinical studies aimed at assessing the usefulness of DHEA as an adjuvant in TB patients.

Abstract
Evolutionary and comparative approaches can yield novel insights into human adaptation and disease. Endometriosis and polycystic ovary syndrome (PCOS) each affect up to 10% of women and significantly reduce the health, fertility, and quality of life of those affected. PCOS and endometriosis have yet to be considered as related to one another, although both conditions involve alterations to prenatal testosterone levels and atypical functioning of the hypothalamic-pituitary-gonadal (HPG) axis. Here, we propose and evaluate the novel hypothesis that endometriosis and PCOS represent extreme and diametric (opposite) outcomes of variation in HPG axis development and activity, with endometriosis mediated in notable part by low prenatal and postnatal testosterone, while PCOS is mediated by high prenatal testosterone. This diametric disorder hypothesis predicts that, for characteristics shaped by the HPG axis, including hormonal profiles, reproductive physiology, life-history traits, and body morphology, women with PCOS and women with endometriosis will manifest opposite phenotypes. To evaluate these predictions, we review and synthesize existing evidence from developmental biology, endocrinology, physiology, life history, and epidemiology. The hypothesis of diametric phenotypes between endometriosis and PCOS is strongly supported across these diverse fields of research. Furthermore, the contrasts between endometriosis and PCOS in humans parallel differences among nonhuman animals in effects of low versus high prenatal testosterone on female reproductive traits. These findings suggest that PCOS and endometriosis represent maladaptive extremes of both female life-history variation and expression of sexually dimorphic female reproductive traits. The diametric disorder hypothesis for endometriosis and PCOS provides novel, unifying, proximate, and evolutionary explanations for endometriosis risk, synthesizes diverse lines of research concerning the two most common female reproductive disorders, and generates future avenues of research for improving the quality of life and health of women.

Abstract
The management of patients with diminished ovarian reserve (DOR) remains one of the most challenging tasks in IVF clinical practice. Despite the promising results obtained from animal studies regarding the importance of androgens on folliculogenesis, the evidence obtained from clinical studies remains inconclusive. This is mainly due to the lack of an evidence-based methodology applied in the available trials and to the heterogeneity in the inclusion criteria and IVF treatment protocols. In this review, we analyze the available evidence obtained from animal studies and highlight the pitfalls from the clinical studies that prevent us from closing the chapter of this line of research.

Adjuvant treatment strategies in ovarian stimulation for poor responders undergoing IVF: a systematic review and network meta-analysis. Hum Reprod Update 2020; 26:247-263. [PMID: 32045470 DOI: 10.1093/humupd/dmz046] [Citation(s) in RCA: 99] [Impact Index Per Article: 24.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 11/10/2019] [Accepted: 11/19/2019] [Indexed: 12/29/2022] Open
Abstract
BACKGROUND Despite great advances in assisted reproductive technology, poor ovarian response (POR) is still considered as one of the most challenging tasks in reproductive medicine. OBJECTIVE AND RATIONALE The aim of this systemic review is to evaluate the role of different adjuvant treatment strategies on the probability of pregnancy achievement in poor responders undergoing IVF. Randomized controlled trials (RCTs) comparing 10 adjuvant treatments [testosterone, dehydroepiandrosterone (DHEA), letrozole, recombinant LH, recombinant hCG, oestradiol, clomiphene citrate, progesterone, growth hormone (GH) and coenzyme Q10 (CoQ10)] were included. SEARCH METHODS Relevant studies published in the English language were comprehensively selected using PubMed, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL) until 11 July 2018. We included studies that investigated various adjuvant agents, including androgen and androgen-modulating agents, oestrogen, progesterone, clomiphene citrate, GH and CoQ10, during IVF treatment and reported subsequent pregnancy outcomes. The administration of GnRH analogs and gonadotrophins without adjuvant treatment was set as the control. We measured study quality based on the methodology and categories listed in the Cochrane Collaboration Handbook. This review protocol was registered with PROSPERO (CRD42018086217). OUTCOMES Of the 1124 studies initially identified, 46 trials reporting on 6312 women were included in this systematic review, while 19 trials defining POR using the Bologna criteria reporting 2677 women were included in the network meta-analysis. Compared with controls, DHEA and CoQ10 treatments resulted in a significantly higher chance of clinical pregnancy [odds ratio (OR) 2.46, 95% CI 1.16 to 5.23; 2.22, 1.08-4.58, respectively]. With regard to the number of retrieved oocytes, HCG, oestradiol and GH treatments had the highest number of oocytes retrieved [weighted mean difference (WMD) 2.08, 0.72 to 3.44; 2.02, 0.23 to 3.81; 1.72, 0.98 to 2.46, compared with controls, respectively]. With regard to the number of embryos transferred, testosterone and GH treatment led to the highest number of embryos transferred (WMD 0.72, 0.11 to 1.33; 0.67, 0.43 to 0.92; compared with controls, respectively). Moreover, GH resulted in the highest oestradiol level on the HCG day (WMD 797.63, 466.45 to 1128.81, compared with controls). Clomiphene citrate, letrozole and GH groups used the lowest dosages of gonadotrophins for ovarian stimulation (WMD 1760.00, -2890.55 to -629.45; -1110.17, -1753.37 to -466.96; -875.91, -1433.29 to -282.52; compared with controls, respectively). CoQ10 led to the lowest global cancelation rate (OR 0.33, 0.15 to 0.74, compared with controls). WIDER IMPLICATIONS For patients with POR, controlled ovarian stimulation protocols using adjuvant treatment with DHEA, CoQ10 and GH showed better clinical outcomes in terms of achieving pregnancy, and a lower dosage of gonadotrophin required for ovulation induction. Furthermore, high-level RCT studies using uniform standards for POR need to be incorporated into future meta-analyses.

Abstract
Poor ovarian response (POR) is one of the most challenging problems in assisted reproduction. Several strategies have been used to improve pregnancy rates. The use of Clomiphene Citrate (CC) has been shown to improve ovarian stimulation outcomes and decrease gonadotropin requirements in women of advanced reproductive age. However, the combination of CC and gonadotropins to improve pregnancy rates after in IVF in poor responders is still unexplored due to the small number of trials with few participants. This is a prospective cohort trial involving 12 patients diagnosed with poor ovarian response who underwent ovarian stimulation during the period between June 2015 and September of 2017. All patients were treated with the maximum dose of gonadotropins (hMG, 300 IU/day, hMG group) according to a short gonadotropin/GnRH antagonist protocol. In a subsequent cycle those patients underwent the same stimulation protocol with the addition of 100 mg of CC from day 3 to day 7 (CC-hMG group). Supplementation with 100 mg of CC resulted in a statistically significant increase in estradiol levels, number of follicles and number of oocytes retrieved, as well as an increase in the number of total embryos available for transfer. Furthermore, a significant reduction was observed in cancellation rates in the CC-hMG group. Two clinical pregnancies, which resulted in two live births and 3 biochemical pregnancies were achieved in the CC/hMG group. Furthermore, by employing open-source, biological data we identified a common gene (Estrogen Receptor 1, ESR1) between genetic targets of clomiphene treatment and POR which could explain the benefits of clomiphene in this group of patients. In conclusion, the addition of CC 100 mg to the stimulation regimen in women diagnosed with POR and previous failed IVF cycles could improve stimulation results, but this study could not demonstrate any benefit in terms of clinical pregnancies and live births. The effectiveness of this treatment requires further investigation.

Abstract
Introduction
A systematic review and meta-analysis were conducted to evaluate the efficacy of dehydroepiandrosterone (DHEA) supplementation in patients with diminished ovarian reserve (DOR) and/or poor ovarian response (POR) who were undergoing in vitro fertilization or intracytoplasmic sperm injection (IVF/ICSI).
Patients and Methods
We searched the PubMed, EMBASE, Web of Science, and Cochrane Library electronic databases for literature published until July 2018. The analysis included randomized controlled trials (RCTs) of the effects of DHEA versus placebo on IVF or ICSI. Two independent reviewers extracted information from the reports and evaluated the quality of the studies. Overall, we identified nine prospective RCTs involving 833 patients.
Results
Compared to the controls, patients treated with DHEA exhibited increases in the number of retrieved oocytes (mean difference, 0.91; 95% confidence interval [CI], 0.23 – 1.59; p = 0.009), clinical pregnancy rate (relative risk [RR] = 1.27; 95% CI, 1.01 – 1.61; p = 0.04), and live birth rate (RR, 1.76; 95% CI, 1.17 – 2.63; p = 0.006). However, there was no intergroup difference in the miscarriage rate (RR, 0.37; 95% CI, 0.12 – 1.13; p = 0.08).
Conclusion
DHEA supplementation improved the outcomes of IVF/ICSI in women with DOR or POR.

Abstract
PURPOSE The aim of the present systematic review and meta-analysis was to summarize evidence on the effectiveness of testosterone supplementation for poor ovarian responders (POR) on IVF outcomes. The primary outcome was live birth rate (LBR); secondary outcomes were clinical pregnancy rate (CPR), miscarriage rate (MR), total and MII oocytes, and total embryos. METHODS This meta-analysis of randomized controlled trials (RCTs) evaluates the effects of testosterone administration before/during COS compared with a control group in patients defined as POR. The primary outcome was live birth rate (LBR); secondary outcomes were clinical pregnancy rate (CPR), miscarriage rate (MR), total and MII oocytes, and total embryos. Pooled results were expressed as risk ratio (RR) or mean differences (MD) with 95% confidence interval (95% CI). Sources of heterogeneity were investigated through sensitivity and subgroup analysis. All analyses were performed by using the random-effects model. RESULTS Women receiving testosterone showed higher LBR (RR 2.29, 95% CI 1.31-4.01, p = 0.004), CPR (RR 2.32, 95% CI 1.47-3.64, p = 0.0003), total oocytes (MD = 1.28 [95% CI 0.83, 1.73], p < 0.00001), MII oocytes (MD = 0.96 [95% CI 0.28, 1.65], p = 0.006), and total embryos (MD = 1.17 [95% CI 0.67, 1.67], p < 0.00001) in comparison to controls, with no difference in MR (p = ns). Sensitivity and subgroup analysis did not provide statistical changes to the pooled results. CONCLUSIONS Testosterone therapy seems promising to improve the success at IVF in POR patients. Further RCTs with rigorous methodology and inclusion criteria are still mandatory.

Abstract
Objective This study aimed to assess a novel protocol designed to improve poor ovarian
response through intra-ovarian androgenization. The endpoints were: number
of oocytes and mature oocytes retrieved, fertilization, cancellation and
pregnancy rates. Methods This prospective crossover study enrolled poor responders from previous
ovarian stimulation cycles submitted to a novel protocol called ANDRO-IVF.
The protocol included pretreatment with transdermal AndroGel(r) (Besins) 25
mg, oral letrozole 2.5 mg and subcutaneous hCG 2500 IU; cycle control was
performed with estradiol valerate and micronized progesterone; ovarian
stimulation was attained with gonadotropins FSH/LH 450 IU, GnRH antagonist
and hCG 5000 IU. Results Fourteen poor responders were enrolled. One patient did not meet the
inclusion criteria. Thirteen patients previously summited to the standard
protocol were offered the ANDRO-IVF Protocol.-Standard Protocol: Mean age:
35.30 years; cancellation rate: 61.53%; mean number of MII oocytes retrieved
per patient: 1.8; fertilization rate: 33.33%. Only two patients had embryo
transfers, and none got pregnant.-ANDRO-IVF Protocol: Mean age: 35.83 years;
cancellation rate: 7.69%; mean number of oocytes retrieved per patient:
5.58, MII oocytes: 3.91. ICSI was performed in 84.61% of the patients and a
mean of 1.5 embryos were transferred per patient. Fertilization rate: 62.5%;
cumulative pregnancy rate: 16.66%; mean duration of stimulation: 9.77
days. Conclusion ANDRO-IVF allows intra-ovarian androgenization by increasing serum and
intra-follicular androgen levels and preventing androgen aromatization. This
protocol apparently improved clinical outcomes of poor responders in
parameters such as number of oocytes retrieved and clinical pregnancy rates.
Further randomized controlled trials are needed to confirm these
findings.

Abstract
BACKGROUND In vitro fertilization (IVF) patients receive various adjuvant therapies to enhance success rates, but the true benefit is actively debated. Growth hormone (GH) and dehydroepiandrosterone (DHEA) supplementation were assessed in women undergoing fresh IVF transfer cycles and categorized as poor prognosis from five criteria. METHODS Data were retrospectively analyzed from 626 women undergoing 626 IVF cycles, where they received no adjuvant, GH alone, or GH-DHEA in combination. A small group received DHEA alone. The utilization of adjuvants was decided between the attending clinician and the patient depending on various factors including cost. RESULTS Despite patients being significantly older with lower ovarian reserve, live birth rates were significantly greater with GH alone (18.6%) and with GH-DHEA (13.0%) in comparison to those with no adjuvant (p < 0.003). No significant difference was observed between the GH groups (p = 0.181). Overall, patient age, quality of the transferred embryo, and GH treatment were the only significant independent predictors of live birth chance. Following adjustment for patient age, antral follicle count, and quality of transferred embryo, GH alone and GH-DHEA led to a 7.1-fold and 5.6-fold increase in live birth chance, respectively (p < 0.000). CONCLUSION These data indicated that GH adjuvant may support more live births, particularly in younger women, and importantly, the positive effects of GH treatment were still observed even if DHEA was also used in combination. However, supplementation with DHEA did not indicate any potentiating benefit or modify the effects of GH treatment. Due to the retrospective design, and the risk of a selection bias, caution is advised in the interpretation of the data.

Abstract
Basic research into a possible link between serum and follicular fluid androgen concentrations to detemine whether androgen supplementation in low responders affects follicular endocrine milieu is still lacking. Ninety-seven women (aged 28-43 years) undergoing one natural IVF cycle without any hormone stimulation were analysed. Serum and follicular fluid were collected at the time of follicle aspiration, and the concentrations of LH, total testosterone, oestradiol, dehydroepiandrosterone and anti-Mullerian hormone (AMH) were determined. Serum LH (P = 0.003) and AMH (P = 0.026) concentrations, and follicular fluid AMH (P = 0.015) decreased with increasing age. Within follicular fluid, total testosterone was correlated with oestradiol (P < 0.001) and AMH (P = 0.010); LH correlated with AMH (P = 0.005). Correlation analysis of serum and follicular fluid hormone concentrations revealed that LH, oestradiol and AMH correlated (P < 0.001), whereas testosterone did not. Testosterone serum concentrations did not correlate with other follicular fluid hormones, such as dehydroepiandrosterone, oestradiol and AMH, whereas serum LH correlated with follicular flulid AMH (P < 0.008). Follicular fluid hormone concentrations seem to be independent from serum testosterone. Therefore, it is questionable whether an increase in serum testosterone concentration by androgen supplementation could improve the follicular endocrine milieu.

Abstract
Poor ovarian response represents an increasingly common problem. This systematic review was aimed to identify the most effective treatment protocol for poor response. We searched MEDLINE, EMBASE, and The Cochrane Library from 1980 to October 2015. Study quality assessment and meta-analyses were performed according to the Cochrane recommendations. We found 61 trials including 4997 cycles employing 10 management strategies. Most common strategy was the use of gonadotropin-releasing hormone antagonist (GnRHant), and was compared with GnRH agonist protocol (17 trials; n = 1696) for pituitary down-regulation which showed no significant difference in the outcome. Luteinizing hormone supplementation (eight trials, n = 847) showed no difference in the outcome. Growth hormone supplementation (seven trials; n = 251) showed significant improvement in clinical pregnancy rate (CPR) and live birth rate (LBR) with an odds ratio (OR) of 2.13 (95% CI 1.06-4.28) and 2.96 (95% CI 1.17-7.52). Testosterone supplementation (three trials; n = 225) significantly improved CPR (OR 2.4; 95% CI 1.16-5.04) and LBR (OR 2.18; 95% CI 1.01-4.68). Aromatase inhibitors (four trials; n = 223) and dehydroepiandrosterone supplementation (two trials; n = 57) had no effect on outcome.

Abstract
OBJECTIVE To provide the best available evidence on the role of dehydroepiandrosterone (DHEA) treatment in improving the outcome of in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in women with poor ovarian response (POR). STUDY DESIGN A randomized controlled trial conducted in Cairo University hospitals and Dar Al-Teb subfertility and assisted conception centre, Giza, Egypt. 140 women undergoing IVF/ICSI with POR according to the Bologna criteria were randomly divided into 2 equal groups. The study group received DHEA 25mg three times daily for 12 weeks before the IVF/ICSI cycles and the control group did not receive DHEA. Controlled ovarian stimulation (COH) was started on the second day of menstruation using human menopausal gonadotropins, cetrotide 0.25mg was started when the leading follicle reached 14mm. The main outcome measures were the clinical pregnancy rate, ongoing pregnancy rate, retrieved oocytes, fertilization rate, gonadotropins doses and COH days. RESULTS The DHEA group had significantly higher clinical pregnancy rate (32.8% vs 15.7%, p=0.029), ongoing pregnancy rate (28.5% vs 12.8%), retrieved oocytes (6.9±3 vs 5.8±3.1, p=0.03), fertilization rate (62.3±27.4 vs 52.2±29.8, p=0.039), significantly less gonadotropins doses (3383±717.5IU vs 3653.5±856IU, p=0.045) and COH days (11.6±1.8 vs 12.6±1.06, p=0.001). CONCLUSION DHEA increases the number of oocytes, fertilization rate, fertilized oocytes, and clinical pregnancy rate and ongoing pregnancy rate in women with POR according to the Bologna criteria. DHEA was well tolerated by the patients and was associated with less COH days and gonadotropins doses. REGISTRATION NUMBER www.clinicaltrials.govNCT02151006.

Abstract
BACKGROUND Infertility is a condition affecting 10% to 15% of couples of reproductive age. It is generally defined as "the failure to achieve a clinical pregnancy after 12 months or more of regular unprotected sexual intercourse". The treatment of infertility may involve manipulation of gametes or of the embryos themselves. These techniques are together known as assisted reproductive technology (ART). Practitioners are constantly seeking alternative or adjunct treatments, or both, in the hope that they may improve the outcome of assisted reproductive techniques. This Cochrane review focusses on the adjunct use of synthetic versions of two naturally-produced hormones, dehydroepiandrosterone (DHEA) and testosterone (T), in assisted reproduction.DHEA and its derivative testosterone are steroid hormones proposed to increase conception rates by positively affecting follicular response to gonadotrophin stimulation, leading to greater oocyte yields and, in turn, increased chance of pregnancy. OBJECTIVES To assess the effectiveness and safety of DHEA and testosterone as pre- or co-treatments in subfertile women undergoing assisted reproduction. SEARCH METHODS We searched the following electronic databases, trial registers and websites up to 12 March 2015: the Cochrane Central Register of Controlled Trials (CENTRAL), the Menstrual Disorders and Subfertility Group (MDSG) Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL, electronic trial registers for ongoing and registered trials, citation indexes, conference abstracts in the Web of Science, PubMed and OpenSIGLE. We also carried out handsearches. There were no language restrictions. SELECTION CRITERIA We included randomised controlled trials (RCTs) comparing DHEA or testosterone as an adjunct treatment to any other active intervention, placebo, or no treatment in women undergoing assisted reproduction. DATA COLLECTION AND ANALYSIS Two review authors independently selected studies, extracted relevant data and assessed them for risk of bias. We pooled studies using fixed-effect models. We calculated odds ratios (ORs) for each dichotomous outcome. Analyses were stratified by type of treatment. There were no data for the intended groupings by dose, mode of delivery or after one/more than one cycle.We assessed the overall quality of the evidence for the main findings using the GRADE working group methods. MAIN RESULTS We included 17 RCTs with a total of 1496 participants. Apart from two trials, the trial participants were women identified as 'poor responders' to standard IVF protocols. The included trials compared either testosterone or DHEA treatment with placebo or no treatment.When DHEA was compared with placebo or no treatment, pre-treatment with DHEA was associated with higher rates of live birth or ongoing pregnancy (OR 1.88, 95% CI 1.30 to 2.71; eight RCTs, N = 878, I² statistic = 27%, moderate quality evidence). This suggests that in women with a 12% chance of live birth/ongoing pregnancy with placebo or no treatment, the live birth/ongoing pregnancy rate in women using DHEA will be between 15% and 26%. However, in a sensitivity analysis removing trials at high risk of performance bias, the effect size was reduced and no longer reached significance (OR 1.50, 95% CI 0.88 to 2.56; five RCTs, N = 306, I² statistic = 43%). There was no evidence of a difference in miscarriage rates (OR 0.58, 95% CI 0.29 to 1.17; eight RCTs, N = 950, I² statistic = 0%, moderate quality evidence). Multiple pregnancy data were available for five trials, with one multiple pregnancy in the DHEA group of one trial (OR 3.23, 95% CI 0.13 to 81.01; five RCTs, N = 267, very low quality evidence).When testosterone was compared with placebo or no treatment we found that pre-treatment with testosterone was associated with higher live birth rates (OR 2.60, 95% CI 1.30 to 5.20; four RCTs, N = 345, I² statistic = 0%, moderate evidence). This suggests that in women with an 8% chance of live birth with placebo or no treatment, the live birth rate in women using testosterone will be between 10% and 32%. On removal of studies at high risk of performance bias in a sensitivity analysis, the remaining study showed no evidence of a difference between the groups (OR 2.00, 95% CI 0.17 to 23.49; one RCT, N = 53). There was no evidence of a difference in miscarriage rates (OR 2.04, 95% CI 0.58 to 7.13; four RCTs, N = 345, I² = 0%, low quality evidence). Multiple pregnancy data were available for three trials, with four events in the testosterone group and one in the placebo/no treatment group (OR 3.09, 95% CI 0.48 to 19.98; three RCTs, N = 292, very low quality evidence).One study compared testosterone with estradiol and reported no evidence of a difference in live birth rates (OR 2.06, 95% CI 0.43 to 9.87; one RCT, N = 46, very low quality evidence) or miscarriage rates (OR 0.70, 95% CI 0.11 to 4.64; one RCT, N = 46, very low quality evidence).The quality of the evidence was moderate, the main limitations being lack of blinding in the included trials, inadequate reporting of study methods, and low event and sample sizes in some trials. AUTHORS' CONCLUSIONS In women identified as poor responders undergoing ART, pre-treatment with DHEA or testosterone may be associated with improved live birth rates. The overall quality of the evidence is moderate. There is insufficient evidence to draw any conclusions about the safety of either androgen. Definitive conclusions regarding the clinical role of either androgen awaits evidence from further well-designed studies.

Abstract
Dehydroepiandrosterone (DHEA) is the most abundant steroid hormone in the circulation and has potent multifunctional activity. Epidemiological evidence suggests that levels of serum DHEA decrease with advancing age, and this has been associated with onset or progression of various age-related ailments, including cognitive decline and dementia, cardiovascular disease, and obesity. Consequently, these findings have sparked intense research interest in DHEA supplementation as an "antiaging" therapy. Currently, DHEA is being used by 25% of in vitro fertilization (IVF) clinicians as an adjuvant in assisted reproductive programs, yet the therapeutic benefit of DHEA is unclear. Here, we examined the use of novel DHEA-containing oral troches in patients undertaking IVF and investigated the impact of these troches on their serum androgen profile. This retrospective study determined the androgen profile of 31 IVF patients before (baseline) and after DHEA supplementation (with DHEA). Baseline serum measurements of testosterone (total and free), DHEA sulfate (DHEAS), sex hormone-binding globulin (SHBG), and androstenedione were made before and after supplementation. Each patient received DHEA troches containing 25 mg of micronized DHEA, and troches were administered sublingually twice daily for a period of no greater than 4 months. Adjuvant treatment with DHEA boosted the serum concentration of a number of androgen-related analytes, including total and free testosterone, androstenedione, and DHEAS, while serum SHBG remained unchanged. Supplementation also significantly increased the free-androgen index in IVF patients. Interestingly, the increase in serum analyte concentration following DHEA supplementation was found to be dependent on body mass index (BMI), but not individual age. Patients with the lowest BMI (<20.0 kg/m(2)) tended to have lower testosterone and DHEAS, but higher SHBG and androstenedione levels in comparison with other BMI groups postsupplementation. However, patients in the highest BMI group (>30.0 kg/m(2)) tended to have lower androgen responses following DHEA supplementation, but these were not statistically different from the corresponding baseline level. This method of DHEA administration results in a similar enhancement of testosterone, DHEAS, and androstenedione levels in comparison with other methods of administration. Furthermore, we showed that BMI significantly influences DHEA uptake and metabolism, and that BMI should be carefully considered during dosage calculation to ensure a significant and robust androgen-profile boost.

Abstract
Dehydroepiandrosterone (DHEA) and its sulfated form dehydroepiandrosterone sulfate (DHEAS) are the most abundant circulating steroid hormones in humans. In animal studies, their low levels have been associated with age-related involuntary changes, including reduced lifespan. Extrapolation of animal data to humans turned DHEA into a 'superhormone' and an 'anti-aging' panacea. It has been aggressively marketed and sold in large quantities as a dietary supplement. Recent double-blind, placebo-controlled human studies provided evidence to support some of these claims. In the elderly, DHEA exerts an immunomodulatory action, increasing the number of monocytes, T cells expressing T-cell receptor gamma/delta (TCRγδ) and natural killer (NK) cells. It improves physical and psychological well-being, muscle strength and bone density, and reduces body fat and age-related skin atrophy stimulating procollagen/sebum production. In adrenal insufficiency, DHEA restores DHEA/DHEAS and androstenedione levels, reduces total cholesterol, improves well-being, sexual satisfaction and insulin sensitivity, and prevents loss of bone mineral density. Normal levels of CD4+CD25(hi) and FoxP3 (forkhead box P3) are restored. In systemic lupus erythematosus, DHEA is steroid-sparing. In an unblinded study, it induced remission in the majority of patients with inflammatory bowel disease. DHEA modulates cardiovascular signalling pathways and exerts an anti-inflammatory, vasorelaxant and anti-remodelling effect. Its low levels correlate with increased cardiovascular disease and all-cause mortality. DHEA/DHEAS appear protective in asthma and allergy. It attenuates T helper 2 allergic inflammation, and reduces eosinophilia and airway hyperreactivity. Low levels of DHEAS accompany adrenal suppression. It could be used to screen for the side effects of steroids. In women, DHEA improves sexual satisfaction, fertility and age-related vaginal atrophy. Many factors are responsible for the inconsistent/negative results of some studies. Overreliance on animal models (DHEA is essentially a human molecule), different dosing protocols with non-pharmacological doses often unachievable in humans, rapid metabolism of DHEA, co-morbidities and organ-specific differences render data interpretation difficult. Nevertheless, a growing body of evidence supports the notion that DHEA is not just an overrated dietary supplement but a useful drug for some, but not all, human diseases. Large-scale randomised controlled trials are needed to fine-tune the indications and optimal dosing protocols before DHEA enters routine clinical practice.

Abstract
OBJECTIVE To evaluate to the efficacy of testosterone, dehydroepiandrosterone (DHEA) and growth hormone (GH) supplementations in patients with diminished ovarian reserve (DOR) in assisted reproductive technology (ART) cycles. MATERIALS AND METHODS A retrospective cohort including 33 women with 81 ART cycles were aged and ovarian reserve matched 52 women with 102 conventional in vitro fertilization (IVF)/intra-cytoplasmic sperm injection (ICSI) protocol. Administration of DHEA for 12 weeks and transdermal testosterone for 4 weeks as pretreatment adjuvant and luteal start GH in DOR patient treatment arm compared to conventional IVF/ICSI cycles. RESULTS The number of follicles >14 mm, number of oocytes, number of metaphase 2 oocytes and fertilisation rate were significantly higher in ISIK protocol (IP). The clinical pregnancy rate (CPR) per embryo transfer of the IP was 38.2% (13/34). The cancellation rate of cycles decreased significantly from 54.5 % (24/44) to 8.1% (3/37) with the IP, while the OPR was 35.3% (12/34). CONCLUSIONS Our study has shown that even the poorest responders could achieve clinical pregnancy after inducing ovarian folliculogenesis with a combination of transdermal testosterone, DHEA and GH.

Abstract
INTRODUCTION Assisted reproduction techniques are the frequent treatment of infertility. Despite the advances in science and technology, the management of poor responder patients is still considered as one of the most urgent problems. The lack of unified definition makes the management of the poor responder patients very difficult. The aim of this review is to examine and compare the different studies done about the problem of poor responder patients. METHODS On an online research of MEDLINE/PUBMED, we found several studies on pharmacological treatment for poor responders' patients. RESULTS Our review shows that in the years numerous therapies for the management of these patients who do not respond to ovarian stimulation have been evaluated and studied, but the main problem is the large and still not well-defined meaning of poor responder women. CONCLUSION The management of the poor responder patients is very difficult. Currently, there is no any standard treatment for poor responder patients. Considering the importance of the problem, it is important to identify a diagnostic and therapeutic target. Our review shows that there are many studies with different therapeutic approaches which deserve further in-depth study to standardize diagnostic and therapeutic target.

Abstract
The use of dehydroepiandrosterone (DHEA) may improve ovarian stimulation outcomes in women of advanced reproductive age and could reduce embryo aneuploidy. In this prospective study, 48 women diagnosed with poor ovarian response received DHEA supplementation for at least 12 weeks. These women were compared with a group of poor responders (n = 113) who did not receive supplementation. During the study period, patients taking day 2 FSH and oestradiol were measured monthly before and after treatment. Stimulation characteristics, stimulation outcome and clinical outcome (clinical pregnancy and live birth rates) were reported. Evaluation of anti-Müllerian hormone (AMH) was carried out before initiation of treatment and immediately before the subsequent stimulation. Supplementation with DHEA for at least 12 weeks resulted in a modest, but statistically significant, increase in AMH levels and decrease in baseline FSH (P < 0.001 and P = 0.007, respectively). Administration of DHEA had no effect on any of the stimulation parameters nor was there any difference in clinical pregnancy rates and live birth rates between the two groups. Supplementation with DHEA significantly affects women with poor prognosis undergoing ovarian stimulation for IVF. Patients should be counselled about the uncertain effectiveness, potential side-effects and cost of this treatment.

Abstract
BACKGROUND Dehydroepiandrosterone (DHEA) is now widely used as an adjuvant to IVF treatment protocols in poor responders. However, clinical evidence for DHEA on improvement of ovarian response and IVF outcome is still limited, the validity of the results of the earlier studies, especially the varied inclusion criteria, is a subject of debate. Recently, the ESHRE Working Group developed a new definition, the Bologna criteria. The aim of the current study was to investigate the potential effect of DHEA treatment on in vitro fertilization (IVF) outcome of poor ovarian responders that fulfill the Bologna criteria. METHODS This study investigated 386 poor ovarian responders that fulfill the Bologna criteria. Patients underwent IVF-ET treatment with the GnRH antagonist protocol. The study group contained 189 patients, who received 75 mg of DHEA daily (25 mg three times daily) before the IVF cycle. The control group was composed of 197 patients who received infertility treatment, but did not receive DHEA. The IVF outcome parameters in each group were compared. RESULTS The study and control groups did not show statistically significant differences in terms of patient demographics characteristics, mean numbers of oocytes retrieved, mature oocytes, fertilization rate, cleavage rate, or embryo availability. While the DHEA group demonstrated significantly higher implantation rates (18.7% vs. 10.1%; P<0.01) and ongoing PRs (26.7% vs. 15.8%; P<0.05) as compared with the control. CONCLUSIONS DHEA pre-treatment does not significantly increase oocyte yield. However, the ongoing PRs in this subgroup of women are significantly higher after DHEA administration, suggesting that DHEA may increase IVF results by improving oocyte and embryo quality.

Abstract
In view of the conflicting data regarding the efficacy of the gonadotropin-releasing hormone (GnRH) antagonist/letrozole (A/L) protocol for treating poor responders undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI), this systematic review and meta-analysis aimed to compare the effectiveness of the A/L protocol and the microdose GnRH agonist flare up (MF) protocol for such treatment. MEDLINE, EMBASE, Web of Science, and the China National Knowledge Infrastructure were searched for studies comparing the A/L and MF protocols for treating poor responders undergoing IVF/ICSI. We retrieved reports of three trials with data for 688 cycles in women. The clinical pregnancy rate was significantly decreased with the A/L compared with MF protocol (RR 0.70; 95% CI: 0.57-0.86; p = 0.001), the duration of gonadotrophin stimulation was lower with the A/L than MF protocol (MD -1.25; 95% CI: -2.37 to -0.12; p = 0.03). Moreover, there was no significant difference in cycle cancellation rate, number of oocytes retrieved, and the total dose of gonadotrophin between the two protocols. In conclusions, the clinical pregnancy rate may be lower with the A/L than MF protocol for treating poor responsers undergoing IVF/ICSI, but large-scale randomised controlled trials are needed to assess the A/L protocol.

Abstract
In order to identify and describe the effectiveness of transdermal testosterone pretreatment on poor ovarian responders, MEDLINE, EMBASE, the Cochrane library and the Chinese biomedical database were searched for randomized controlled trials (RCTs). Three RCTs, which compared the outcomes of female pretreatment with transdermal testosterone prior to in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) with those of control groups, were included in the present review. The three RCTs enrolled a total of 221 randomized subjects. The meta-analysis revealed that females who received transdermal testosterone treatment prior to their IVF/ICSI cycle had a two-fold increase in live birth rate [risk ratio (RR)=2.01, 95% confidence interval (CI) 1.03–3.91], clinical pregnancy rate (RR=2.09, 95% CI 1.14–3.81) and a significantly more oocyte retrieved [mean difference (MD)=1.36, 95% CI 0.82–1.90]. The current findings provide evidence that pretreatment with transdermal testosterone may improve the clinical outcomes for poor ovarian responders undergoing IVF/ICSI. However, the results should be interpreted with caution due to the small sample size of the studies used and the heterogeneities. Further good quality RCTs would be needed to reach further conclusions.

Abstract
Metabolism of glucose during pregnancy reflects the equilibrium between lactogenic hormones stimulating insulin production and counterregulatory hormones inducing insulin resistance. In physiological pregnancies, insulin-mediated glucose uptake is substantially decreased and insulin secretion increased to maintain euglycemia. This common state of peripheral insulin resistance arises also due to steroid spectra changes. In this review article, we have focused on the role of steroid hormones (androgens, estrogens, gestagens, mineralocorticoids, glucocorticoids, as well as secosteroid vitamin D) in the impairment of glucose tolerance in pregnancy and in the pathogenesis of gestational diabetes mellitus. This article is part of a Special Issue entitled 'Pregnancy and Steroids'.

Abstract
Women with diminished ovarian reserve often respond poorly to controlled ovarian stimulation resulting in retrieval of fewer oocytes and reduced pregnancy rates. It has been proposed that pre-IVF Dehydroepiandrosterone (DHEA) adjuvant therapy may improve ovarian response and pregnancy rates in women with diminished ovarian reserve. This meta-analysis aims to investigate efficacy of DHEA as an adjuvant to improve ovarian response and IVF outcome in women with diminished ovarian reserve. Electronic databases were searched under the following terms: (DHEA) and (diminished ovarian reserve) and/or (poor response). Studies were included if they reported at least one of the following outcomes; clinical pregnancy rate, number of oocytes retrieved, miscarriage rate. We identified 22 publications determining effects of DHEA in clinical trials. Only 3 controlled studies were eligible for meta-analysis. There was no significant difference in the clinical pregnancy rate and miscarriage rates between women pre-treated with DHEA compared to those without DHEA pre-treatment (RR 1.87, 95% CI 0.96-3.64; and RR 0.59, 95% CI 0.21-1.65, respectively). The number of oocytes retrieved (WMD -1.88, 95% CI -2.08, 1.67; P < 0.001) was significantly lower in the DHEA group. In conclusion, based on the limited available evidence from a total of approximately 200 IVF cycles, there are insufficient data to support a beneficial role of DHEA as an adjuvant to controlled ovarian stimulation in IVF cycle. Well-designed, randomised controlled trials as well as more exact knowledge about DHEA mechanisms of action are needed to support use of DHEA in standard practice for poor-responders.

Abstract
The results of several studies about the effectiveness of recombinant luteinizing hormone (rLH) supplementation in poor responder in vitro fertilization (IVF) patients were conflicting. To evaluate the current available data regarding the efficacy of rLH supplementation in poor responders, a meta-analysis was performed. A systemic search was performed without language limitation but restricted to randomized controlled trial (RCT). We mainly explored MEDLINE, EMBASE, CNKI and Cochrane Library for the relevant studies. Three studies were considered eligible for inclusion. The meta-analysis indicated that rLH supplementation did not increase the ongoing pregnancy rate in poor responders (OR 1.30, 95% CI: 0.80, 2.11). Furthermore, there was no significant difference in the number of oocytes retrieved, total dose of rFSH used, total duration of stimulation, number of retrieved metaphase II oocytes and cycle cancellation rate between the study and control groups. In conclusions, the available evidence does not support the addition of rLH in poor responders treated with rFSH and GnRHa for IVF. It was inconclusive. Future research should be based on strict criteria to define poor responders, and large, well-designed RCTs are necessary to definitively answer the important question of whether there was need to use rLH in poor responders undergoing IVF.

Abstract
ABSTRACT
Diminished ovarian reserve predicts diminished ovarian response to stimulation but does not predict cycle fecundity. It has been recently defined by ESHRE, the Bologna's criteria, according to which at least two of the following three features should be present: (1) Age >40 years/any other risk factor for DOR, (2) abnormal ovarian reserve test, i.e. antral follicle count, AMH, (3) poor ovarian response in a previous stimulated cycle, i.e. less than three follicles after standard gonadotropin stimulation. Poor response to maximal stimulation on two previous occasions also defines DOR.
The treatment options are limited. Avoiding the GnRH agonist long protocol and stimulation with microdose flare or antagonist protocol yields better results. Adjuvant therapy with LH, DHEAS and growth hormone shows some benefit in improving the oocyte yield. It is advisable to perform ICSI for all obtained oocytes and some advocate assisted hatching. Pregnancy rates are, however, poor and often these patients require ovum donation. Developing tests that will diagnose DOR in a low-risk population will allow women to plan their reproductive careers early.

Abstract
Poor responders are a heterogeneous population, with some patients displaying a diminished ovarian reserve and others a poor ovarian reserve with preserved granulosa cell function. Androgen and LH/hCG supplementation has been advocated for poor responders, mainly those >40 years old. Although androgens synergistically act with FSH to support folliculogenesis, and ovarian androgen secretion declines with age, there is still no evidence that androgen therapy is actually effective to improve ovarian FSH sensitivity. The main reason seems to be that theca cell function has not been appropriately assessed in patients at risk of poor response. The definition of theca insufficiency is hampered by methodologic shortcomings in routine bioassays. Provocative tests for theca cells might help to identify those patients who could benefit from androgen supplementation. The lack of data regarding theca cells in these patients might contribute to explaining the absence of evidence for a positive effect of androgen therapy.

Abstract
PURPOSE OF REVIEW Androgens and particularly dehydroepiandrosterone (DHEA) have been advocated as adjuncts to ovarian stimulation in women with diminished ovarian reserve. Given the limited number of options in these women it is understandable that both physicians and patients resort to treatments that are not evidence based. RECENT FINDINGS DHEA is such an adjunct and has been recently used extensively in women responding poorly to gonadotropins and women of advanced age seeking treatment with assisted reproductive techniques. Although androgens may be biologically plausible, current evidence is not sufficient to prove their effectiveness. SUMMARY Until well designed studies show a beneficial effect of DHEA supplementation in women with a diminished ovarian reserve, its widespread use should be discouraged. The patients should be counseled regarding the experimental nature of such a treatment.

Abstract
BACKGROUND The aim of this meta-analysis was to evaluate the role of androgens or androgen-modulating agents on the probability of pregnancy achievement in poor responders undergoing IVF. METHODS Medline, EMBASE, CENTRAL, Scopus and Web of Science databases were searched for the identification of randomized controlled trials evaluating the administration of testosterone, dehydroepiandrosterone (DHEA), aromatase inhibitors, recombinant luteinizing hormone (rLH) and recombinant human chorionic gonadotrophin (rhCG) before or during ovarian stimulation of poor responders. RESULTS In two trials involving 163 patients, pretreatment with transdermal testosterone was associated with an increase in clinical pregnancy [risk difference (RD): +15%, 95% confidence interval (CI): +3 to +26%] and live birth rates (RD: +11%, 95% CI: +0.3 to +22%) in poor responders undergoing ovarian stimulation for IVF. No significant differences in clinical pregnancy and live birth rates were observed between patients who received DHEA and those who did not. Similarly, (i) the use of aromatase inhibitors, (ii) addition of rLH and (iii) addition of rhCG in poor responders stimulated with rFSH for IVF were not associated with increased clinical pregnancy rates. In the only eligible study that provided data, live birth rate was increased in patients who received rLH when compared with those who did not (RD: +19%, 95% CI:+1 to +36%). CONCLUSIONS Based on the limited available evidence, transdermal testosterone pretreatment seems to increase clinical pregnancy and live birth rates in poor responders undergoing ovarian stimulation for IVF. There is insufficient data to support a beneficial role of rLH, hCG, DHEA or letrozole administration in the probability of pregnancy in poor responders undergoing ovarian stimulation for IVF.
