Abstract
The management of young patients with cancer presents several unique challenges. In general, these patients are ill prepared for the diagnosis and the impact on their fertility. With the improved survival for all tumour types and stages, the need for adequate fertility counselling and a multidisciplinary approach in the reproductive care of these patients is paramount. Recent advances in cryopreservation techniques allow for the banking of spermatozoa, oocytes, embryos and ovarian tissue without compromising survival. This Canadian Fertility and Andrology Society (CFAS) guideline outlines the current understanding of social and medical issues associated with oncofertility, and the medical and surgical technologies available to optimize future fertility.

Abstract
OBJECTIVE To evaluate the efficacy of manifold ovarian stimulation protocols for patients with poor ovarian response. METHODS PubMed, Embase, Cochrane Library and Web of Science were systematically searched until February 14, 2021. Primary outcomes included clinical pregnancy rate per initiating cycle and low risk of cycle cancellation. Secondary outcomes included number of oocytes retrieved, number of metaphase II (MII) oocytes, number of embryos obtained, number of transferred embryos, endometrial thickness on triggering day and estradiol (E2) level on triggering day. The network plot, league table, rank probabilities and forest plot of each outcome measure were drawn. Therapeutic effects were displayed as risk ratios (RRs) or mean differences (MDs) with 95% confidence intervals (CIs). RESULTS This network meta-analysis included 15 trials on 2173 participants with poor ovarian response. Delayed start GnRH antagonist was the best regimen in terms of clinical pregnancy rate per initiating cycle (74.04% probability of being the optimal), low risk of cycle cancellation (75.30%), number of oocytes retrieved (68.67%), number of metaphase II (MII) oocytes (97.98%) and endometrial thickness on triggering day (81.97%), while for E2 level on triggering day, microdose GnRH agonist (99.25%) was the most preferred. Regarding number of embryos obtained and number of transferred embryos, no statistical significances were found between different ovarian stimulation protocols. CONCLUSION Delayed start GnRH antagonist and microdose GnRH agonist were the two superior regimens in the treatment of poor ovarian response, providing favorable clinical outcomes. Future investigation is needed to confirm and enrich our findings.

Comparative analyses in transcriptome of human granulosa cells and follicular fluid micro-environment between poor ovarian responders with conventional controlled ovarian or mild ovarian stimulations. Reprod Biol Endocrinol 2022; 20:54. [PMID: 35313911 PMCID: PMC8935846 DOI: 10.1186/s12958-022-00926-1] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Accepted: 03/07/2022] [Indexed: 01/02/2023] Open
Abstract
BACKGROUND Both mild and conventional controlled ovarian stimulation are the frequently used protocols for poor ovarian responders. However, there are some debates about which treatment is better. Moreover, little is known about the follicular physiology after the two ovarian stimulation protocols. This study was intended to investigate the features in granulosa cells and follicular fluid micro-environment after the two different ovarian stimulation protocols in poor responders. METHODS Granulosa cells RNA were sequenced using Illumina Hiseq technology. Specific differently expressed genes and proteins were verified by real-time quantitative PCR and Western blot analysis. Moreover, hormone and cytokine concentrations in the follicular fluid were measured by electrochemiluminescence immunoassay and enzyme-linked immunoabsorbent assay. The correlation between the results of molecular experiments and the laboratory outcomes were analyzed by Spearman correlation analysis. RESULTS The differentially expressed genes between the two groups were involved in 4 signaling pathways related to the follicular development; three proteins pertinent to the TGF-β signaling pathway were expressed differently in granulosa cells between the two, and the constituents in the follicular fluid were also different. Further, a correlation between the TGF-β signaling pathway and the good-quality embryo was observed. CONCLUSIONS The present study made a comparison for the first time in the transcriptome of human granulosa cells and the follicular fluid micro-environment between poor responders with the conventional controlled ovarian stimulation or the mild ovarian stimulation, showing that the TGF-β signaling pathway may correlate with the good-quality of embryos in the mild group, which may be instrumental to the choice of optimal management for IVF patients.

Abstract
OBJECTIVE The aim of the present retrospective study was to investigate the effectiveness of single-dose gonadotropin releasing hormone (GnRH) antagonist administration, the day after human chorionic gonadotropin (hCG) triggering for final oocyte maturation, on the prevention of premature luteinization in patients with diminished ovarian reserve in in-vitro fertilization (IVF) cycles. The secondary objective of the study was to search the effect of this protocol on pregnancy outcomes. METHODS This is a retrospective study including 267 infertile patients who have single antral follicle seen with ultrasonography on the 2nd or 3rd day of the menstrual cycle before starting IVF treatment. We randomized patients into two groups. The case group comprised patients who had single-dose GnRH antagonist injection the day after hCG triggering formed, and the patients who had the standard treatment regime formed the control group. In both groups, the oocytes were collected 36 hours after hCG injection. RESULTS The premature ovulation rate was significantly low in the case group compared with the control group (6.86 versus 20.6% per scheduled cycle) (p = 0.022). Also, the oocyte retrieval rate (93.14 versus 67.87% per scheduled cycle) (p = 0.013), the oocyte maturity rate (79.42 versus 47.87%) (p = 0.041), the fertilization rate (65.68 versus 34.54%) (p = 0.018), and the embryo transfer rate per scheduled cycle (44.11 versus 18.78%) (p = 0.003) were higher in the GnRH antagonist group than in the control group. CONCLUSION The administration of GnRH antagonist the day after hCG trigger in IVF treatments of patients with diminished ovarian reserve enabled a significant decrease in the rate of premature ovulation but had no effect on live birth rate.

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.

Comparative study between single versus dual trigger for poor responders in GnRH-antagonist ICSI cycles: A randomized controlled study. Int J Gynaecol Obstet 2020; 152:395-400. [PMID: 33011968 DOI: 10.1002/ijgo.13405] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Revised: 07/15/2020] [Accepted: 09/29/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE To investigate whether dual triggering of final oocyte maturation with a combination of gonadotropin-releasing hormone (GnRH) agonist and human chorionic gonadotropin (hCG) can improve the number of retrieved oocytes and clinical pregnancy rate in poor responders undergoing in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) cycles using a GnRH-antagonist protocol. METHODS A randomized controlled trial included poor ovarian responders indicated for ICSI using a GnRH-antagonist protocol. They were divided equally into two groups: group I received 10 000 units of hCG plus 0.2 mg of triptorelin while group II received 10 000 units of hCG only for triggering of ovulation. The primary outcome parameter was the number of oocytes retrieved. Secondary outcomes included metaphase II oocytes number, cancellation rate, number of obtained embryos, chemical and clinical pregnancy rates. RESULTS One hundred and sixty women were included in the study, with 80 women in each treatment group. Dual triggering was associated with higher number of retrieved oocytes (5.3 ± 1.9 vs 4.5 ± 2.4, P=0.014), metaphase II oocytes (3.8 ± 1.4 vs 3.1 ± 1.7, P=0.004), total and grade 1 embryos (2.7 ± 1.1 and 2.3 ± 1.0 vs 1.9 ± 1.2 and 1.1 ± 0.2, P=0.001 and 0.021 respectively), and transferred embryos (2.2 ± 0.9 vs 1.6 ± 0.9, P=0.043, and lower cancellation rate (7.5% vs 20%, P=0.037) compared with single triggering. There were significantly higher chemical (25% vs 11.3%, P=0.039) and clinical (22.5% vs 8.8%, P=0.028) pregnancy rates in women with dual triggering compared with those with single triggering. CONCLUSION Dual triggering is associated with better IVF outcome in poor responders compared with single trigger. Clinical trial registration NCT04008966.

Abstract
Background Ovarian stimulation (OS) for poor ovarian response (POR) patients is still a major challenge in assisted reproductive techniques. Aromatase inhibitors as co-treatment in antagonist protocol are suggested to these patients, but there are controversial reports. Objective To evaluate the effectiveness Letrozole (LZ) as adjuvant treatment in gonadotropin-releasing hormone (GnRH)-antagonist protocol in POR patients undergoing in vitro fertilization/ intracytoplasmic sperm injection cycles. Materials and Methods This double-blind randomized clinical trial was conducted in Arash women's hospital. One hundred sixty infertile women with POR based on Bologna criteria were allocated into two groups randomly: LZ + GnRH-antagonist (LA) and placebo + GnRH-antagonist (PA) groups. In the experimental group, the patients received 5 mg LZ on the first five days of OS with 150 IU of recombinant human follicle-stimulating hormone (rFSH) and 150 IUof human menopausal gonadotropin (HMG). The cycle outcomes were compared between groups. Results The total number of retrieved oocytes and the metaphase II oocytes in LA-treated group were significantly higher than those in the control group (p = 0.008, p = 0.002). The dosage of hMG used and the duration of OS and antagonist administration in LZ-treated group were significantly lower than those of the control group. The number of patients with no oocyte, in the control group, was higher than the LZ-treated group, and the clinical pregnancy rate in LA-treated group (25%) was higher than the control group (18%); however, the differences were not significant statistically. Conclusion Adding 5 mg of LZ to rFSH/hMG antagonist protocol may improve the in vitro fertilization/intracytoplasmic sperm injectioncycle outcome in POR patients.

Abstract
OBJECTIVE To assess the available evidence comparing effectiveness of ovarian stimulation (OS) using clomiphene citrate (CC) and/or letrozole (LTZ) to reduce follicle-stimulating hormone (FSH) consumption compared with standard OS. METHODS We performed a systematic review and meta-analysis of randomized controlled trials that compared reproductive outcomes following in-vitro fertilization. We searched 11 electronic databases and hand-searched the reference lists of included studies and related reviews. We stratified the results, separating studies according to the oral agent used (CC or LTZ) and the characteristics of the included women (expected poor ovarian response or other women). When combining the results of the included studies, we assessed the relative risk (RR) for live birth, clinical pregnancy, miscarriage and cycle cancelation, the Peto odds ratio (OR) for ovarian hyperstimulation syndrome (OHSS) and mean difference (MD) for the number of oocytes retrieved and FSH consumption. RESULTS A total of 22 studies were included in the review. Considering women with expected poor ovarian response, the available evidence suggested that using CC to reduce FSH consumption during OS provided similar rates of live birth (RR, 0.9 (95% CI, 0.6-1.2), moderate-quality evidence) and clinical pregnancy (RR, 1.0 (95% CI, 0.8-1.4), moderate-quality evidence); the use of LTZ did not cause a relevant change in the number of oocytes retrieved (MD, -0.4 (95% CI, -0.9 to 0.1), high-quality evidence). Considering the studies evaluating other women, the available evidence suggested that using CC to reduce FSH consumption during OS reduced the number of oocytes retrieved (MD, -4.6 (95% CI, -6.1 to -3.0), high-quality evidence) and risk of OHSS (Peto OR, 0.2 (95% CI, 0.1-0.3), moderate-quality evidence), while results were similar for rates of live birth (RR, 0.9 (95% CI, 0.7-1.1), moderate-quality evidence) and clinical pregnancy (RR, 1.0 (95% CI, 0.8-1.1), high-quality evidence). The quality of the evidence was low or very low for other outcomes. CONCLUSION The use of CC to reduce FSH consumption in women with expected poor ovarian response has the advantage of providing similar reproductive outcomes with reduced costs. For the other women, the use of CC for reducing FSH consumption has the additional advantage of reducing OHSS, but also reduces the total number of oocytes retrieved. More studies are needed to evaluate the effect of LTZ for the same purpose. Future studies should focus on cumulative pregnancy per oocyte retrieval, patient dissatisfaction and agreement to repeat the cycle if not pregnant, which are important outcomes for clinical decisions.

A multicenter retrospective study. J Gynecol Obstet Hum Reprod 2017; 46:629-635. [PMID: 28843783 DOI: 10.1016/j.jogoh.2017.08.001] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2017] [Revised: 07/25/2017] [Accepted: 08/18/2017] [Indexed: 11/16/2022]
Abstract
OBJECTIVE The principal outcome was to assess the ovarian response to controlled hyperstimulation during in vitro fertilization (IVF) with or without micro-injection (ICSI) in patients whom ovarian reserve testing revealed a discrepancy between the serum levels of FSH and AMH. The secondary outcome was to determine whether AMH and FSH profiles could predict the IVF/ICSI response. STUDY DESIGN This was a multicenter, retrospective study analysing all controlled ovarian hyperstimulation cycles with attempted fresh embryo transfer(s) carried out during IVF/ICSI treatment and in which the AMH level had been assayed between January 01, 2008 and December 31, 2011. This enabled us to form 2 control groups (NOR, normal ovarian reserve: normal AMH and FSH and DOR, diminished ovarian reserve: diminished AMH, increased FSH) and 2 study groups (DAMH: diminished AMH, normal FSH and NAMH: normal AMH, increased FSH). The principal assessment criterion was quantitative ovarian response to stimulation defined by the mean number of oocytes punctured, the secondary assessment criterion the qualitative response to stimulation defined by the pregnancy rate per cycle. RESULTS We were able to analyse 1803 stimulation cycles. The mean number of oocytes punctured was significantly reduced in the DAMH and DOR groups compared to the NAMH and NOR groups (5.2±3.9 and 4.1±3.3 vs. 11.5±7 and 9.5±5.6, respectively [P<0.01]). The pregnancy rate per initiated cycle was significantly reduced in the DAMH and DOR groups compared to the NAMH and NOR groups (20% and 24% vs. 32 and 35%, respectively [P<0.01]). Live birth rates did not differ between the groups however. Multivariate analysis with logistic regression revealed that AMH, FSH and age independently had an effect on the number of oocytes punctured, although the effect exerted by AMH seemed to be preponderant (OR: 2.75: 95%CI [2.39-3.19]). AMH appeared to be the sole factor independently predictive of pregnancy per cycle. CONCLUSION The serum AMH level appears to provide an additional item of discriminatory information, which should not be overlooked. Ovarian reserve work-up should include routine AMH assay.

Abstract
BACKGROUND/AIM Mild stimulation protocols have been implemented to be offered to subfertile patients who respond poorly to ovarian stimulation. We aimed to compare the efficacy of mild versus conventional gonadotropin-releasing hormone (GnRH)-agonist and antagonist protocols in poor responders undergoing in vitro fertilization/intra-cytoplasmic sperm injection (IVF/ICSI) cycles. PATIENTS AND METHODS A total of 58 poorly-responding patients were divided into two groups: mild group (n=33), receiving clomiphene citrate 100 mg and 0.25 mg of cetrorelix with 150 IU of gonadotrophins daily; conventional group (n=25), undergoing the long GnRH-agonist or -antagonist protocols. The primary outcome was the number of cumulus oocyte complexes (COCs) retrieved. RESULTS A lower number of COCs [median (range)=1 (0-4) vs. 3 (0-8.4), p<0.001] was retrieved in the mild stimulation compared to the conventional group. Secondary outcomes favored the conventional group, whereas live birth (9.1% vs. 12%), clinical pregnancy (12.1% vs. 20%) and miscarriage rate (40% vs. 40%) were similar in the two groups. CONCLUSION Mild ovarian stimulation is inferior to conventional regimes when applied to poor responders undergoing IVF/ICSI, in terms of the numbers of retrieved COCs.

A randomized, single-blind, prospective trial comparing three different gonadotropin doses with or without addition of letrozole during ovulation stimulation in patients with poor ovarian response. Eur J Obstet Gynecol Reprod Biol 2016; 203:30-4. [PMID: 27236602 DOI: 10.1016/j.ejogrb.2016.05.027] [Citation(s) in RCA: 39] [Impact Index Per Article: 4.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2016] [Revised: 04/24/2016] [Accepted: 05/13/2016] [Indexed: 11/25/2022]
Abstract
OBJECTIVE The aim of this randomized controlled trial (RCT) was to investigate whether IVF outcomes would differ between patients with POR who received three different gonadotropin doses with or without the addition of letrozole during ovulation stimulation. STUDY DESIGN Only those who fulfilled two of the three Bologna criteria were included to the study. 95 patients met the inclusion criteria and agreed to participate in the study. In the first group, 31 patients were treated with 450IU gonadotropins. In the second group, 31 patients were treated with 300IU gonadotropins. The third group comprised 33 patients and was treated with 150IU gonadotropins in combination with letrozole. RESULTS The results indicate that differences in doses of hMG and rFSH in patients with POR result in a similar number of retrieved MII and fertilized oocytes, similar fertilization rates, number of transferred embryos, implantation, cancelation, chemical, clinical, and ongoing pregnancy rates. CONCLUSIONS Increasing the dose of gonadotropins during ovulation stimulation is an intuitively appealing approach when the patient is a poor responder. However, increasing the dose does not necessarily improve the reproductive outcome. Using a mild stimulation with addition of letrozole was as effective as stimulation with higher doses of gonadotropins alone in this patient population.

Abstract
BACKGROUND Our objective was to evaluate the effectiveness of clomiphene citrate (CC) vs. letrozole (L) plus human menopausal gonadotropin (hMG) in gonadotropin releasing hormone (GnRH) antagonist protocol in poor prognosis women with previous failed ovarian stimulation undergoing intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS This retrospective cohort study included cycles with CC and L plus hMG/GnRH antagonist protocols of 32 poor responders who had failed to have ideal follicles to be retrieved during oocyte pick-up (OPU) or embryo transfer (ET) at least for 2 previous in vitro fertilization (IVF) cycles with microdose flare protocol or GnRH antagonist protocol from January 2006 to December 2009. Main outcome measures were implantation, clinical pregnancy and live birth rates per cycle. Duration of stimulation, mean gonadotropin dose used, endometrial thickness, number of mature follicles, serum estradiol (E2) and progesterone (P) levels on the day of human chorionic gonadotropin (hCG) administration, number of retrieved oocytes and fertilization rates were also evaluated. RESULTS A total number of 42 cycles of 32 severe poor responders were evaluated. Total gonadotropin consumption was significantly lower (1491 ± 873 vs. 2808 ± 1581 IU, P=0.005) and mean E2 level on the day of hCG injection were significantly higher in CC group than L group (443.3 ± 255.2 vs. 255.4 ± 285.2 pg/mL, P=0.03). ET, overall pregnancy and live birth rates per cycle were significantly higher in CC than L protocol (27.2 vs. 15%, 13.6 vs. 0% and 4.5 vs. 0%, respectively, P<0.05). CONCLUSION Severe poor responders who had previously failed to respond to microdose or GnRH antagonist protocols may benefit from CC plus hMG/GnRH antagonist protocol despite high cancellation rate.

Abstract
OBJECTIVE To compare the effects of fresh embryo transfers (ET) and elective frozen/thawed embryo transfers (eFET) on implantation, clinical pregnancy, and live birth rates in poor ovarian responders, as defined by the Bologna criteria. MATERIALS AND METHODS All electronic databases of embryo transfers between January 2011 and January 2014 were retrospectively reviewed. Two hundred fifty-nine of all the fresh ET and 96 of all eFET were included into the study. An antagonist protocol with letrozole was used for the controlled ovarian hyperstimulation (COH) in all participants. RESULTS The mean age was 36.9 years (range, 21-43 years) in the fresh ET arm and 37.2 years (range, 21-43 years) in the eFET arm (p=0.45). The clinical pregnancy rate was 35% (90/259) versus 29% (28/96); the abortion rate was 27% (20/75) versus 36% (9/25); and the live birth rate was 21% (55/259) versus 17% (16/99). There were no significant differences between groups and p values were 0.32, 0.52, and 0.42, respectively. The mean E2 level was 389 (range, 50-2055 pg/mL) in the fresh ET group (on hCG day) and 418 pg/mL (range, 121-3073 pg/mL) in the eFET group (on day 14 of cycle) (p=0.122). No differences were found between the two groups with respect to the total number of retrieved oocytes (p=0.55) and number of metaphase II (MII) oocytes (p=0.81). The number of embryo transfers was statistically different (p=0.005). The effects of age, total number of retrieved oocytes, number of MII oocytes, type of treatment, number of ET, and the day of ET and E2 level to live birth outcomes were investigated using binary logistic regresion analyses, and no stastical effect was determined by any of the parameters. P values were p=0.50, 0.66, 0.45, 0.30, 0.30, 0.08, and 0.90, respectively. CONCLUSION E2 levels tend to be lower in poor responders, thus the receptivity of the endometrium may be damaged less than normal, which may explain why pregnancy results are the same between eFET and ET groups.

Abstract
Backgrounds: the prevalence of infertility is up to 10 to 15 % which 9 to 24 % of them are Poor Ovarian Responders (POR). This study was designed to compare two methods of GnRH Agonist Microdose Flareup (MF) and GnRH Antagonist/Letrozole (AL) in treatment of these patients. Methods and Materials: this randomized clinical trial study consisted of 123 patients. In the first step of treatment in both methods FSH, LH, estradiol, anderostandion, testestron in third day of menstruation period and the thickness of endometrium by Transvaginal sonography were evaluated. At the time of HCG injection the thickness of endometrium and follicles which were more than 14mm ware established and hormones were evaluated. Two weeks later serum βhCG and after 6 to 8 weeks Transvaginal sonography were applied to prove the pregnancy. Results: there were 61 patients with mean age of 38.7±4.58 in MF group and 62 patients with mean age of 38.5±4.6 in AL group (P=0.80). At the time of hCG injection there were significant increase in the level of LH, estradiol, thickness of endometrium and follicles more than 14mm in MF patients (P<0.0001). The mean time of ovary stimulation in MF group was 10.72±1.5 and in AL was 8.45±1.2 (P<0.0001). The mean level of gonadotropin which were used was 80.6±20.1 in MF patients and 64.7±16.4 in AL group (P<0.0001). 18 % of MF group and 38.7% in AL group had no normal cycle of ovulation (OR: 2.87, 95% CI: 1.25-6.57, P=0.011). The mean numbers of oocyte and normal fetus in MF was 5.83±3.5 and 3.7±2.5 and in AL was 3±1.69 and 1.4±1.33 (P<0.0001). The number of chemical pregnancy in MF group was 10 (16.4%) and in AL was 3 (4.8%) (OR 3.85, 95% CI: 1.06-14.77, P=0.037). Clinical pregnancy in 10 patients (16.4%) of MF group and 3 (4.8%)in AL was reported. OR 3.85, 95% CI: 1.06-14.77, P=0.037). Conclusion: this study showed that MF method of pregnancy leads to more positive results in pregnancy based on chemical and clinical evaluation in comparison with AL and is advised for poor responder patients.

Abstract
BACKGROUND Advancements in the treatments for cancer and autoimmune and other hematologic conditions continue to improve survival and cure rates. Despite those changes, various gonadotoxic agents and other treatments can still compromise the future fertility of many women. Progress in medical and surgical reproductive technologies has helped to offset the reproductive consequences of the use of gonadotoxic therapies, and allows for future fertility and normal pregnancy. METHODS A review of the literature was performed to outline the pathophysiology of gonadotoxicity from various treatments. The success of fertility preservation, fertility sparing, and cryopreservation options are reviewed. Barriers and facilitators to referral and oncofertility treatment in Canada are also outlined. RESULTS According to the quality of the evidence, recommendations are made for fertility assessment, patient referral, cryopreservation, and other assisted reproductive technologies. CONCLUSIONS To ensure ongoing fertility in women undergoing gonadotoxic treatments, assisted reproductive technologies can be combined with a multidisciplinary approach to patient assessment and referral.

Abstract
OBJECTIVE To compare the new delayed start protocol against the conventional gonadotropin (Gn)-releasing hormone antagonist protocol in poor responders (PORs). STUDY DESIGN A total of 160 women with poor response to previous in vitro fertilization (IVF) cycle were randomized either to start Gn then Cetrotide 0.25 subcutaneously (sc) added when leading follicle (DF) reach >12 mm or Cetrotide 0.25 mg sc started first from day 2 to day 8 then Gn therapy was added and Cetrotide restarted when DF reach >12 mm. RESULTS There was a statistically significant difference between conventional and delayed start protocols regarding the needed dose of Gn for stimulation (4368 ± 643 and 3798 ± 515), level of estradiol (E2; 778 ± 371 and 1076 ± 453), and endometrial thickness at human chorionic gonadotropin triggering (8.6 ± 1.8 and 9.8 ± 1.9), the number of DF (3.4 ± 1.5 and 4.9 ± 2.1), the number of retrieved follicles (2.4 ± 2.1 and 4.3 ± 2.5), and successful embryo transfer (13 vs 16), respectively (P < .05). There was a highly statistically significant difference between the 2 study groups regarding the number of oocytes fertilized (1.2 ± 2.0 vs 3.3 ± 1.4), metaphase II oocytes (0.9 ± 1.0 vs 2.7 + 1.6), and grade I embryos (0.7 ± 0.9 vs 2.1 + 1.1; P < .001). The chemical pregnancy, clinical pregnancy, and abortion rate showed a statistically significant difference between the 2 study groups (P value .003 and .006, respectively). CONCLUSION Delayed start protocol significantly improved clinical pregnancy rate and IVF cycle parameters in PORs.

Abstract
BACKGROUND To compare the effect of the GnRH antagonist/letrozole/gonadotropin protocol with the microdose GnRH agonist flare-up protocol in poor ovarian responders for intracytoplasmic sperm injection. MATERIALS AND METHODS One hundred twenty-one consecutive patients suspected of having or with a history of poor ovarian response between January 2009 and June 2010, who were undergoing ICSI were enrolled. The microdose flareup (MF) protocol was used in 79 patients and the estradiol + progesterone/letrozole + gonadotropin and GnRH antagonist (EP/ALG) protocol was used in 42 patients. RESULTS Age of the patients, duration of infertility, basal FSH, the total gonadotropin consumption, duration of stimulation, E2 level on the day of hCG administration, the number of embryo transferred, the fertilization rate, implantation rate, clinical pregnancy rate and the live birth rate were not statistically different (p > 0.05). Only the number of oocytes retrieved was significantly higher in the EP/LGA group (1.7 ± 0.7 versus 2.6 ± 0.6). CONCLUSION The EP/LGA protocol has no significant improvement against the microdose flare-up protocol in poor responder patients.

Abstract
PURPOSE To compare the effects of microdose GnRH-a flare-up, GnRH antagonist/aromatase inhibitor letrozole and GnRH antagonist/clomiphene citrate protocols on IVF outcomes in poor responder patients. METHODS Of 225 patients, 83 patients were in microdose flare-up group (Group 1), 70 patients were in GnRH antagonist/letrozole group (Group 2) and 72 patients were in GnRH antagonist/clomiphene citrate group (Group 3). Demographic and endocrine characteristics, the total number of oocytes retrieved, cancellation rate and clinical pregnancy rate were collected Results: Total dosage of gonadotropins (p=0.002) and serum E2 levels on the day of hCG administration (p=0.010) were significantly higher and duration of stimulations (p=0.03) was significantly longer in group 1. The number of oocytes retrieved was significantly greater in group 1 and 2 when compare to those of group 3 (p=0,000). There was a trend towards increasing cycle cancellation rates with GnRH antagonist/clomiphene citrate and GnRH antagonist/letrozole. CONCLUSION Our finding suggest that the results of microdose flare-up protocol are better than other two used treatment protocols, in terms of maximum estradiol levels, number of mature oocytes retrieved, and cancellation rate and it still seems to be superior the ovarian stimulation regime for the poor responder patients.

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
One of the most vexing challenges in the practice of reproductive medicine is the management of the "poor responder," specifically the patient manifesting an inadequate follicular response to ovarian stimulation. Poor response predicts a reduction in the number of mature oocytes retrieved, with the consequences of fewer embryos available for selection and transfer, reduced pregnancy rates, and a markedly decreased likelihood of residual embryos for cryopreservation. This chapter reviews the definition and prediction of poor response and discusses strategies that have been developed and incorporated into the reproductive endocrinologist's clinical armamentarium in an effort to optimize outcomes for these women. It should be stated at the outset that no single approach is successful for all patients, and that there is currently no firm clinical consensus regarding the relative efficacy of the different stimulation protocols. This arises in part due to inconsistency regarding the definition of what constitutes a poor response and a paucity of well-designed, randomized controlled trials.

Abstract
Assisted reproductive technologies (ART) encompass fertility treatments, which involve manipulations of both oocyte and sperm in vitro. This chapter provides a brief overview of ART, including indications for treatment, ovarian reserve testing, selection of controlled ovarian hyperstimulation (COH) protocols, laboratory techniques of ART including in vitro fertilization (IVF), and intracytoplasmic sperm injection (ICSI), embryo transfer techniques, and luteal phase support. This chapter also discusses potential complications of ART, namely ovarian hyperstimulation syndrome (OHSS) and multiple gestations, and the perinatal outcomes of ART.

Abstract
BACKGROUND To compare the IVF outcomes of letrozole/antagonist and microdose GnRH agonist flare up protocols in poor ovarian responders undergoing intracytoplasmic sperm injection. MATERIALS AND METHODS A randomized controlled trial was performed in patients with one or more previous failed IVF cycles in which four or less oocytes were retrieved when the gonadotrophin starting dose was at least 300 IU/day. Sixty patients were randomized by computer-generated list to receive either letrozole/antagonist (mild stimulation) n = 30 or GnRH-a protocol (microdose flare) n = 30. RESULTS Both groups were similar with respect to background and hormonal characteristics (age, duration of infertility, BMI, FSH, LH and E2). The clinical pregnancy rate per cycle was similar in both groups (13.3 vs. 16.6%; OR = 0.769; 95% CI = 0.185, 3.198). The doses of used gonadotropins and the number of stimulation days were significantly lower in the letrozole/antagonist protocol. The peak E2 level on the day of hCG, the endometrial thickness, the retrieved oocytes, the number of fertilized oocytes, the number of transferred embryos and the cancellation rate were statistically similar in both groups. CONCLUSIONS The letrozole/antagonist protocol is a cost-effective and patient-friendly protocol that may be used in poor ovarian responders for IVF/ICSI.

DHEA supplementation may improve IVF outcome in poor responders: a proposed mechanism. Eur J Obstet Gynecol Reprod Biol 2013; 168:49-53.

Abstract
OBJECTIVE Dehydroepiandrosterone (DHEA) supplementation for poor responders may improve ovarian response and IVF treatment outcome. This study aimed to determine the mechanism of action of DHEA, and specifically, the stage of folliculogenesis influenced by DHEA. STUDY DESIGN This is a prospective, self-controlled study of poor responders to IVF treatment, comparing day 3 biochemical (anti-Mullerian hormone (AMH), inhibin B and FSH) and ultrasound (antral follicle count (AFC)) ovarian reserve markers and IVF treatment outcome before and after DHEA supplementation of at least 3 months duration. RESULTS Thirty-two women were included. Following DHEA, there was a significant increase in AFC (P=0.0003) without significant changes in the baseline biochemical parameters AMH, inhibin B, or FSH. The enhanced response comprised increased peak estradiol levels (P=0.0005), number of follicles >15 mm, oocytes, MII oocytes and embryos (P=0.004, P=0.00001, P=0.0004 and P=0.0006, respectively) and oocytes number/total FSH dose (P=0.0009). The proportion of cancelled cycles due to very poor response decreased significantly (P=0.02). CONCLUSIONS DHEA does not appear to exert influence via recruitment of pre-antral or very small antral follicles (no change in AMH and inhibin B) but rather by rescue from atresia of small antral follicles (increased AFC).

Abstract
OBJECTIVE To determine the effect of inhibiting aromatase activity on endometrial lesion growth and aromatase expression in a baboon model of induced endometriosis. DESIGN Prospective study. SETTING Primate research institute. ANIMAL(S) Sixteen olive baboons. INTERVENTION(S) Sixteen olive baboons with induced endometriosis were examined with laparoscopy 10 months after disease inoculation. Animals in group 1 (n = 10) were treated with 1.25 mg/d of the aromatase inhibitor (AI) letrozole, and animals in group 2 (n = 6) were given a placebo for a total of 6 months. MAIN OUTCOME MEASURE(S) Total number of endometriotic lesions, morphology, and volume of lesions, as well as semiquantitative reverse transcription-polymerase chain reaction and quantitative polymerase chain reaction for levels of aromatase cytochrome messenger RNA were measured. Ovarian volumes were evaluated before treatment initiation and every 2 months during the study. RESULT(S) Treatment of group 1 animals with an AI significantly decreased lesion volume from baseline measurements, whereas the placebo-treated animals showed an increase in lesion volume. Aromatase messenger RNA levels in lesions in the AI-treated animals were significantly lower compared with the placebo-treated animals. Ovarian volumes were significantly increased at 6 months of AI treatment compared with pretreatment volumes. CONCLUSION(S) These findings suggest that suppression of aromatase cytochrome P450 may inhibit the in vivo growth of endometriotic lesions in baboons.

Abstract
The use of aromatase inhibitors (AIs) in IVF patients remains controversial. AIs can be considered for ovulation induction for IVF in women who are normal and poor responders, are at risk of ovarian hyperstimulation syndrome or thrombosis, who have endometriosis, and/or are undergoing fertility preservation procedures as a result of estrogen-dependent cancers, primarily breast and endometrial cancers. Although the biologic plausibility of the capacity of AIs in IVF patients is promising, results should be interpreted with caution, because the efficacy of AIs needs to be proven in randomized trials.

Abstract
The efficacy of assisted reproductive technologies has improved significantly over the past decades. The main indications for in vitro fertilisation include tubal obstruction, severe male-factor infertility, severe endometriosis, ovulatory dysfunction, diminished ovarian reserve, and infertility of unexplained cause. In vitro fertilisation has also become an effective treatment option for couples wishing to undergo pre-implantation genetic diagnosis or screening, and for those wishing to cryopreserve their oocytes or embryos for preservation of fertility. The management of women in late reproductive age poses a major challenge; the optimum in vitro fertilisation treatment for poor responders remains elusive. The success of in vitro fertilisation treatment can be optimised by taking an individualised, patient-centered approach to controlled ovarian hyperstimulation. Key components involve selection of an appropriate controlled ovarian protocol, close-cycle monitoring, adjustment of gonadotropin dosage to avoid hyper-response, and individualised timing of human chorionic gonadotropin injection. Future directions of assisted reproductive technologies include development of non-invasive embryo selection methods, use of transcriptomics, proteomics, metabolomics, and time-lapse imaging technologies.

Abstract
BACKGROUND Our aim was to study ways to improve IVF success rates in women with suspected endometrial receptivity defects. METHODS We conducted a retrospective cohort study examining the effect of letrozole (aromatase inhibitor) on integrin expression as a marker of endometrial receptivity. We compared IVF outcomes in 97 infertile women who had undergone ανβ3 integrin assessment by immunohistochemistry in mid-luteal endometrial biopsies. Of 79 women undergoing standard IVF, 29 (36.7%) lacked normal integrin expression. Eighteen other women with low integrin were studied after receiving letrozole during early IVF stimulation. An independent set of ανβ3 integrin-negative patients (n = 15) who had undergone repeat endometrial biopsy for integrin testing while taking letrozole were re-evaluated. RESULTS Clinical pregnancy and delivery rates were higher in women with normal ανβ3 integrin expression compared with those who were integrin negative [20/50 (40%) versus 4/29 (13.8%); P = 0.02 and 19/50 (38%) versus 2/29 (7%); P < 0.01, respectively]. In 18 women who received letrozole early in IVF, 11 conceived (61.1%; P < 0.001) compared with integrin-negative patients who did not receive letrozole. In integrin-negative women who were rebiopsied on letrozole, 66.7% reverted to normal integrin expression. Positive endometrial aromatase immunostaining using a polyclonal antibody was a common finding in infertile patients compared with controls. CONCLUSIONS Lack of endometrial ανβ3 integrin expression is associated with a poor prognosis for IVF that might be improved with letrozole co-treatment. Prospective studies are needed to confirm and extend these findings but the data suggest that aromatase expression may contribute to implantation failure in some women.

Abstract
PURPOSE To compare the efficacy of different stimulation protocols on pregnancy outcomes in poor responders undergoing in vitro fertilization (IVF). MATERIALS AND METHODS This was a retrospective study to compare the efficacy of four different protocols including gonadotropin-releasing hormone (GnRH) agonist (long, short and miniflare) and GnRH antagonist on pregnancy outcomes in poor responders. This investigation was performed on 566 poor respond patients who were candidates for IVF. Main outcome measures included the total number of oocytes and mature oocytes retrieved, pregnancy rates, implantation and overall cancellation rates which were compared between four mentioned groups. RESULTS Number of follicles >18 mm on hCG day were significantly higher in GnRH-a long versus GnRH antagonist, GnRH-a short and GnRH-a miniflare protocols. The mean number of oocytes and mature oocytes retrieved were significantly higher in GnRH-a long versus miniflare (4.7 ± 3.05 versus 3.26 ± 2.9 and 3.69 ± 3.1 versus 2.65 ± 2.2, respectively). There were no significant differences in implantation, pregnancy and overall cancellation rates between four groups. CONCLUSION The present study suggests that the application of four different protocols in poor respond patients seem to have similar efficacy in improving clinical outcomes such as implantation, pregnancy rates and cancellation rate even though GnRH-a long protocol yielded more retrieved oocytes and mature oocytes compared to GnRH-a miniflare protocol.

Abstract
Objective To investigate the effectiveness of GnRH antagonist multiple-dose protocol (MDP) with oral contraceptive pill (OCP) pretreatment in poor responders undergoing IVF/ICSI, compared with GnRH antagonist MDP without OCP pretreatment and GnRH agonist low-dose long protocol (LP). Methods A total of 120 poor responders were randomized into three groups according to controlled ovarian stimulation (COS) options; GnRH antagonist MDP after OCP pretreatment (group 1), GnRH antagonist MDP without OCP pretreatment (group 2) or GnRH agonist luteal low-dose LP without OCP pretreatment (group 3). Patients allocated in group 1 were pretreated with OCP for 21days in the cycle preceding COS, and ovarian stimulation using recombinant human FSH (rhFSH) was started 5 days after discontinuation of OCP. Results There were no differences in patients' characteristics among three groups. Total dose and days of rhFSH used for COS were significantly higher in group 3 than in group 1 or 2. The numbers of mature oocytes, fertilized oocytes and grade I, II embryos were significantly lower in group 2 than in group 1 or 3. There were no significant differences in the clinical pregnancy rate and implantation rate among three groups. Conclusion GnRH antagonist MDP with OCP pretreatment is at least as effective as GnRH agonist low-dose LP in poor responders and can benefit the poor responders by reducing the amount and duration of FSH required for follicular maturation.

Abstract
OBJECTIVE To review and summarize data from the scientific literature on the use of androgens to improve ovarian function. DESIGN Review of pertinent literature. SETTING University hospital. PATIENT(S) Women exposed to androgens. INTERVENTION(S) None. MAIN OUTCOME MEASURE(S) Critical review of the literature. RESULT(S) The artificial increase of intra-ovarian androgen concentrations constitutes an attractive concept for improving the deficient ovarian function of poor responders. Data from studies conducted in animals treated with high-dose androgens, together with observations made in hyperandrogenic women or female-to-male transsexuals receiving virilizing androgen doses, indicate that androgens may increase follicle responsiveness to FSH and/or the number of growing follicles in the ovary. Yet, definite clinical demonstration of such a concept still is not available. CONCLUSION(S) Current clinical approaches aiming at increasing androgen availability in the ovary showed conflicting results. Therefore, additional studies using proper strategies to achieving higher intra-ovarian androgen concentrations for longer intervals are required to define the clinical efficiency of androgens in poor responders.

Abstract
OBJECTIVE To compare the efficacy on the cycle performance of 375 versus 450 IU/day gonadotrophin on the microdose flare-up protocol in poor responders. STUDY DESIGN A total of 91 poor responder patients who were treated with the microdose flare-up protocol were enrolled in this study. Group 1 (n = 40) was stimulated with 375 IU/day gonadotrophin. Group 2 (n = 51) was stimulated with 450 IU/day gonadotrophin. Main outcome measurements were accepted as the results of controlled ovarian hyperstimulation, implantation, clinical pregnancy, and live birth rates. RESULTS Baseline characteristics are similar between the two groups. Higher number of oocyte cumulus complexes and lower total gonadotrophin requirement were noted in Group 1 compared with Group 2. Number of metaphase II oocytes and implantation rates were similar between the groups. A trend toward higher clinical pregnancy and live birth rate was observed in Group 1 but these results did not reach statistical significance. CONCLUSIONS Total gonadotrophin costs are lower using the 375 IU/day gonadotrophin compared to the 450 IU/day in poor responders. Additional 75 IU/day does not give any improvement neither embryology nor pregnancy outcomes.

Abstract
PURPOSE To evaluate the effect of adjunctive letrazole or clomiphene in IVF stimulation protocols. METHODS A retrospective analysis of high dose GnRH antagonist IVF cycles (450-600 IU of gonadotropins) that have met poor responder criteria. Selected consecutive cycles in same patients differed solely in presence or absence of adjunctive clomiphene or letrazole. RESULTS Supplementation with clomiphene citrate in poor responders showed significant improvements (p < 0.05) in estradiol levels (1506 vs. 1044 pg/ml), number of dominant follicles (5.6 vs. 3.9), oocytes retrieved (5.2 vs. 3.4) and number of transferred embryos (1.7 vs. 1.1). It significantly improved biochemical pregnancy rates (18.1% vs. 5.9%) while reducing cycle cancellations (11.7% vs. 32.6%). Letrozole supplementation showed similar effects. CONCLUSION Both Clomiphene and Letrazole performed similarly and showed significant effects. However, despite increasing oocyte yield and embryo transfer rates, the overall clinical and live birth rate in this population remained low and showed no measurable increase.

Abstract
INTRODUCTION This retrospective study aimed at analyzing IVF-ET management and outcome after cancellation of a first cycle for poor response. PATIENTS AND METHOD One hundred and forty-two infertile patients were included in this observational study. After an overall analysis on the outcome of the second IVF-ET attempt, a sub-analysis was performed according to the presence or the absence of poor prognostic criteria defined as mentioned: patient age superior to 38 years old, antral follicle count (3-9 mm in diameter) inferior to 10 on cycle day 3 and day 3 serum AMH and FSH levels less than 1 ng/mL and more than 10 IU/mL, respectively. Main outcome measures were the cancellation rates, pregnancy and live birth rates. RESULTS When a controlled ovarian stimulation was performed, patients with poor prognosis had higher cancellation rates (37.8% vs. 13.3%, P<0.004) and lower pregnancy and live birth rates (22.2% vs. 35.0%, P<0.05 and 11.1% vs. 26.1%, P<0.05, respectively) as compared to good prognosis women. CONCLUSION The relatively high cancellation rate in patients with poor prognosis raises the question of the use of IVF modified natural cycle in this group.

Abstract
Aromatase inhibitors have been introduced as a new treatment modality that could challenge clomiphene citrate as an ovulation induction regiment in patients with PCOS. Although several randomized trials have been conducted regarding their use as ovulation induction agents, only few trials are available regarding their efficacy in IVF stimulated cycles. Current available evidence support that letrozole may have a promising role in stimulated IVF cycles, either when administered during the follicular phase for ovarian stimulation. Especially for women with poor ovarian response, letrozole appears to have the potential to increase clinical pregnancy rates when combined with gonadotropins, whereas at the same time reduces the total gonadotropin dose required for ovarian stimulation. However, given that in all of the trials letrozole has been administered in GnRH antagonist cycles, it is intriguing to test in the future how it may perform when used in GnRH agonist cycles. Finally administration of letrozole during luteal phase in IVF cycles offers another treatment modality for patients at high risk for OHSS taking into account that it drastically reduces estradiol levels.

Abstract
Background: There is a trend to cancel intrauterine insemination (IUI) in women with a high response. The aim of this study was to evaluate the efficacy of low-cost in vitro fertilization (IVF) in high-response IUI cycles in comparison with conventional IVF. Methods and materials: A total of 46 women were included in the study. Group A (study group) included 23 women with hyper-response to IUI cycles who were converted to IVF. They received oral letrozole 2.5 mg twice daily from days 3–7 of the menstrual cycle, along with 75 International Units (IU) of recombinant follicle-stimulating hormone on days 3 and 8. Group B (control group) underwent conventional IVF, and received downregulation with a gonadotrophin-releasing hormone agonist followed by stimulation with recombinant follicle-stimulating hormone 150–300 IU/day. Ovulation was triggered by 10,000 IU of human chorionic gonadotrophin, followed by IVF and embryo transfer. The primary outcome measure analyzed was pregnancy rates in both groups. Results: The study group received a significantly lower (P = 0.001) total dose of follicle-stimulating hormone and had significantly (P = 0.002) decreased levels of terminal estradiol. Although the pregnancy rate (30.43% in the study group versus 39.13% in the conventional group) per stimulated cycle was higher in the conventional IVF group, the miscarriage rate (study group 4.34% versus conventional group 13.04%) was also higher, and hence the take-home baby rate (study group 26.08% versus conventional group 30.43%) was more or less similar in both the groups. Conclusion: IVF can be offered to women having a high response to IUI cycles with good pregnancy rates and at low cost compared with use of a conventional protocol, and therefore can be considered more patient-friendly in selected cases.

Abstract
Aromatase inhibitors (AIs) were originally developed for the treatment of advanced breast cancer in postmenopausal women. Their use in reproductive medicine has been extensively studied in the past decade. We reviewed the current strategies for ovulation induction for anovulatory women, mostly women with polycystic ovarian syndrome (PCOS), and the scientific basis for use of AIs in reproductive medicine. The AI, letrozole, is effective in ovulation induction in women with PCOS resistant to clomifene citrate and ovarian stimulation for intrauterine insemination and in vitro fertilization (IVF). Letrozole is an attractive option with its oral route of administration, cost, safety profile and effectiveness in ovulation induction and ovarian stimulation. Letrozole has the potential to be the first-line treatment option for ovulation induction in PCOS women, while its use in ovarian stimulation for IVF deserves further study.

Abstract
The definition presented here represents the first realistic attempt by the scientific community to standardize the definition of poor ovarian response (POR) in a simple and reproducible manner. POR to ovarian stimulation usually indicates a reduction in follicular response, resulting in a reduced number of retrieved oocytes. It has been recognized that, in order to define the poor response in IVF, at least two of the following three features must be present: (i) advanced maternal age or any other risk factor for POR; (ii) a previous POR; and (iii) an abnormal ovarian reserve test (ORT). Two episodes of POR after maximal stimulation are sufficient to define a patient as poor responder in the absence of advanced maternal age or abnormal ORT. By definition, the term POR refers to the ovarian response, and therefore, one stimulated cycle is considered essential for the diagnosis of POR. However, patients of advanced age with an abnormal ORT may be classified as poor responders since both advanced age and an abnormal ORT may indicate reduced ovarian reserve and act as a surrogate of ovarian stimulation cycle outcome. In this case, the patients should be more properly defined as 'expected poor responder'. If this definition of POR is uniformly adapted as the 'minimal' criteria needed to select patients for future clinical trials, more homogeneous populations will be tested for any new protocols. Finally, by reducing bias caused by spurious POR definitions, it will be possible to compare results and to draw reliable conclusions.

Abstract
Many trials have evaluated the use of androgen supplements and androgen-modulating agents to improve outcome of poor responders undergoing IVF treatment. This study conducted a systematic review and meta-analysis of controlled trials of androgen adjuvants (testosterone, dehydroepiandrostereone) and the androgen-modulating agent (letrozole) in poor responders undergoing IVF treatment. Searches were conducted on MEDLINE, EMBASE, Cochrane Library, ISRCTN Register and ISI proceedings. All randomized and non-randomized controlled trials were included. Study selection, quality appraisal and data extraction were performed independently and in duplicate. The main outcome measure was clinical pregnancy rate. The secondary outcome measures were dose and duration of gonadotrophin use, cycles cancelled before oocyte retrieval, oocytes retrieved and ongoing pregnancy rates. A total of 2481 cycles in women considered as poor responders undergoing IVF/intracytoplasmic sperm injection (ICSI) treatment were included in nine controlled trials. Meta-analyses of these studies did not show any significant difference in the number of oocytes retrieved and ongoing pregnancy/live-birth rates with androgen supplementation or modulation compared with the control groups. There is currently insufficient evidence from the few randomized controlled trials to support the use of androgen supplementation or modulation to improve live birth outcome in poor responders undergoing IVF/ICSI treatment.

Abstract
Though a widely utilized term and clinical concept, ovarian reserve (OR) has been only inadequately defined. Based on Medline and PubMed searches we here define OR in its various components, review genetic control of OR, with special emphasis on the FMR1 gene, and discuss whether diminished OR (DOR) is treatable. What is generally referred to as OR reflects only a small portion of total OR (TOR), a pool of growing (recruited) follicles (GFs) at different stages of maturation. Functional OR (FOR) depends on size of the follicle pool at menarche and the follicle recruitment rate. Both vary between individuals and, at least partially, are under genetic control. The FMR1 gene plays a role in defining FOR at all ages. Infertility treatments have in the past almost exclusively only centered on the last two weeks of folliculogenesis, the gonadotropin-sensitive phase. Expansions of treatments into earlier stages of maturation will offer opportunity to significantly improve ovarian stimulation protocols, especially in women with DOR. Dehydroepiandrosterone (DHEA) may represent a first such intervention. Data generated in DHEA-supplemented women, indeed, suggest a new ovarian aging concept, based on aging of ovarian environments and not, as currently is believed, aging oocytes.
