Abstract
Background Poor responders to ovarian stimulation are one of the most challenging populations to treat. As a failed cycle can cause a considerable emotional and economical loss, adequate fertility counseling addressing patients’ expectations are highly important when facing patients with poor ovarian response. The study aimed to evaluate reproductive outcomes and to identify factors associated with live birth (LB) after fresh autologous IVF/intracytoplasmic sperm injection (ICSI) cycles of patients fulfilling the Bologna criteria for poor ovarian response (POR).
Methods A retrospective study included 751 IVF/ICSI treatment cycles which yielded up to three retrieved oocytes, at a tertiary referral hospital between January 2016 and February 2020. A logistic regression analysis was used to adjust for confounders. Results Clinical pregnancy and LB rate per cycle were significantly higher among women younger versus older than 40 years (9.8% and 6.8% vs 4.5% and 2.1%, p < 0.01, respectively). Patients who achieved LB were significantly younger, had higher number of oocytes retrieved, fertilization rate and top-quality embryos (p < 0.05). Multivariable regression analysis identified patient’s age (OR 0.90; 95% CI 0.845–0.97; p = 0.005) and mean number retrieved oocytes (OR 1.95; 95% CI 1.20–3.16; p = 0.007) as factors significantly associated with the probability of a LB. Conclusions The woman’s age and the number of retrieved oocytes are both independent predicting factors of live birth in poor ovarian responders. Considering the risks, the high financial investment and poor reproductive outcomes involved in IVF treatments, raises questions regarding the adequacy of providing treatments in these patients' population. POR younger than 40 years may represent a possible exception due to acceptable probability for a LB.

Abstract
Objective: Follicular Output Rate (FORT) is an efficient quantitative and qualitative marker of ovarian responsiveness to gonadotropins. Transdermal testosterone (TT) has been used as adjuvant therapy to gonadotrophins in order to improve ovarian response in poor responders (PR). The aim of this study was to analyze whether TT can improve follicular sensitivity to gonadotropins using FORT. Methods: This retrospective study, held in a tertiary-care university hospital included 90 PR patients, according to the Bologna criteria. Patients in Group 1 (n = 46) received transdermal application of testosterone preceding gonadotrophin ovarian stimulation under pituitary suppression. In Group 2 (n = 44) ovarian stimulation was carried out with high-dose gonadotrophin in association with minidose GnRH agonist protocol. We analyzed ovarian stimulation parameters and IVF outcomes. We determined antral follicle count (AFC) (3-8 mm) before ovarian stimulation, pre-ovulatory follicle count (PFC) (16-22 mm) and the day of hCG administration. We calculated the FORT using the PFCx100/AFC ratio. Results: Baseline characteristics and ovarian reserve parameters were similar in both groups. FORT and oocytes retrieved were significantly higher in group 1 vs group 2. There were no significant differences in pregnancy rates. In group 1 there was a significant correlation between FORT and AFC. Conclusions: This study suggests that the potential beneficial mechanism of TT in poor responder patients may be based on increasing the antral follicle sensitivity to gonadotrophin. FORT is an excellent tool to demonstrate this.

Abstract
Usually poor ovarian response (POR) to gonadotropins reflects a diminished ovarian reserve (DOR) that gives place to few recruitable follicles despite aggressive stimulation. The reduction in the quantity and quality of the oocytes with advanced age is physiological. However, some women experience DOR much earlier and become prematurely infertile, producing an accelerated follicular depletion towards primary ovarian insufficiency (POI). Up to now, egg donation has been commonly used to treat their infertility. In the last thirty years, specialists in assisted reproduction have focused their attention on the final stages of folliculogenesis, those that depend on the action of gonadotrophins. Nevertheless, recently novel aspects have been known to act in the initial phases, with activating and inhibiting elements. In vitro activation (IVA) combining the in vitro stimulation of the ovarian Akt signaling pathway in ovarian cortex fragments with a method named Hippo-signaling disruption. Later, a simplification of the technique designated Drug-Free IVA have shown encouraging results in patients with POI. Another innovative therapeutic option in these patients is the infusion of bone marrow-derived stem cells (BMDSC) in order to supply an adequate ovarian niche to maintain and/or promote follicular rescue in patients with impaired or aged ovarian reserves. In this review, for the first time, both therapeutic options are addressed together in a common clinical setting. The aim of this review is to analyze the physiological aspects on which these innovative techniques are based; the preliminary results obtained up to now; and the possible therapeutic role that they may have in the future with DOR and POI patients.

Hum Reprod 2019; 33:1696-1704. [PMID: 30016431 DOI: 10.1093/humrep/dey244] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2018] [Accepted: 06/19/2018] [Indexed: 01/18/2023] Open
Abstract
STUDY QUESTION Is the length of the anogenital distance (AGD) a biomarker of ovarian reserve and response to controlled ovarian stimulation (COS)? SUMMARY ANSWER Shorter AGD is associated with presence of poor ovarian response. WHAT IS KNOWN ALREADY Organ development during prenatal life is influenced by the prevailing intrauterine environment, and it has been suggested that nutritional, environmental and toxic factors could affect ovarian reserve set prenatally. AGD is a biomarker of prenatal-hormonal environment and observational studies have shown an association between its length and reproductive parameters in both sexes. STUDY DESIGN, SIZE, DURATION This was a prospective cohort study of 437 women treated with IVF/ICSI conducted in a tertiary-care university hospital between January and December 2016. PARTICIPANTS/MATERIALS, SETTING, METHODS All women underwent their first COS for IVF/ICSI and reached criteria for oocyte retrieval. Based on the number of oocytes obtained, patients were divided into three groups: poor responders (≤3 oocytes) (n = 50), normoresponders (4-15 oocytes) (n = 332) and high responders (>15 oocytes) (n = 55). Before retrieval, the following patient data were recorded: age, body mass index (BMI), ovarian reserve markers (anti-Müllerian hormone [AMH], antral follicle count [AFC] and follicular stimulation hormone [FSH]), cause of infertility, total doses of gonadotropins used and ovarian sensitivity index (OSI). Patients with previous pregnancies, polycystic ovary syndrome (PCOS), endometriosis and previous ovarian or genital surgery were excluded. Anthropometric biomarkers of AGDAC (anus-clitoris) and AGDAF (anus-fourchette) were measured in all patients under sedation on the day of retrieval and before proceeding to oocyte pick-up. Multiple linear regression analyses were used to examine the association between both AGD and ovarian reserve markers, the total units of gonadotropins used, the number of oocytes obtained and the OSI. Logistic regression was used to predict poor response in COS for IVF/ICSI, while accounting for confounders such as age and BMI. MAIN RESULTS AND THE ROLE OF CHANCE Baseline FSH, AMH, AFC and age were significantly different among the three groups of ovarian response, as were the units of gonadotropin used, and the ovarian sensitivity index (OSI) (P < 0.001). Both AGDAC and AGDAF measurements were positively correlated with AMH levels (r = 0.38 and r = 0.21; P < 0.05), AFC (r = 0.41 and r = 0.20; P < 0.05), the OSI (r = 0.24 and r = 0.19; P < 0.05) and the number of oocytes retrieved (r = 0.29 and r = 0.28, respectively; P < 0.05). Conversely, there was a negative correlation between both AGD measurements and the doses of gonadotropins used (r= -0.19 and r= -0.15; P < 0.05). The area under the curve (AUC) for prediction of poor response of AGDAC was 0.70 (95% CI 0.66, 0.75), which was comparable to the classic ovarian reserve markers, such as AFC and AMH. AGDAF showed a significantly worse predictive capacity for poor ovarian response (AUC 0.60 [95% CI 0.55, 0.60]) than AMH and AFC. LIMITATIONS, REASONS FOR CAUTION The population used for the study was a highly selected group of infertile women who underwent COS for IVF, so the findings of this research may not be applicable for general population. Besides, measurement or selection biases might have been possible and must be considered. WIDER IMPLICATIONS OF THE FINDINGS The findings of this study suggest that in utero exposure to certain hormonal environments could affect the ovarian reserve set prenatally. STUDY FUNDING/COMPETING INTEREST(S) None. The authors have no competing interests to declare.

Abstract
Women of advanced age present a major challenge for fertility treatments. This study was designed to assess whether poor ovarian response (POR) according to the Bologna criteria is a significant predictor for live birth in women over 40. The outcomes of subsequent IVF cycles were also studied. The results of 1870 fresh IVF cycles in 1212 women were retrospectively analysed. The live birth per cycle was 3.3 times higher (11.61% versus 3.54%, P < 0.001) in good responders with more than three oocytes collected compared with women with less. Ovarian response defined by oocytes collected, but not by the number of follicles, was independently associated with live birth (odds ratio, 2.0; 95% confidence interval, 1.18 to 3.54; P = 0.009). The occurrence of POR in subsequent IVF cycles was only 55%. No differences in live births were found in persistent POR compared with women with at least one good response. A single episode of POR in a first IVF cycle in older women has a limited predictive value for the outcomes of subsequent cycles. POR in women aged 40-43 years, defined by the number of oocytes retrieved, is a predictor for live birth in IVF.

Abstract
Ovarian reserve reflects the quality and quantity of available oocytes. This reserve has become indispensable for the better understanding of reproductive potential. Measurement of the serum anti-Müllerian hormone (AMH) level allows quantitative evaluation of ovarian reserve. It has been applied to a wide range of clinical conditions, and it is well established that the measurement of serum AMH levels is more useful than qualitative evaluation based on the menstrual cycle. AMH levels are monitored during infertility treatments; in patients undergoing medically assisted reproductive technology; and in the diagnosis of ovarian failure, polycystic ovarian syndrome, and granulosa cell tumor. It is also useful in the evaluation of iatrogenic ovarian damage. Population-based studies have indicated a potential role for serum AMH in the planning of reproductive health management. While AMH is currently the best measure of ovarian reserve, its predictive value for future live births remains controversial. Furthermore, there is a serious practical issue in the interpretation of test results, as currently available assay kits use different assay ranges and coefficients of variation due to the absence of an international reference standard. The pros and cons of the serum AMH level as a definitive measure of ovarian reserve merits further review in order to guide future research.

Abstract
OBJECTIVES Oral contraceptive pills suppress the hypothalomo-pituitary axis, which can affect the ultrasound and endocrine markers used to examine ovarian reserve. The objective of this study was to quantify the ultrasound and endocrine markers of functional ovarian reserve in women using a combined oral contraceptive pill (COCP) for more than a year. METHODS This was a prospective case-control study involving healthy volunteers: 34 women using for more than a year a COCP with hormone-free interval (HFI) were compared to 36 normo-ovulatory, age-matched controls who had not used hormonal contraception within the last year. Volunteers using a COCP underwent a 3D ultrasound examination and had a blood sample taken within the first 4 days of active pill ingestion and those in the control group had the scan and blood test in the early follicular phase (days 2-5) of menstrual cycle. The main outcome measure was the difference in antral follicle counts stratified according to size and anti-Müllerian hormone (AMH), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and estradiol (E2) levels. RESULTS There were no significant differences in the number of small antral follicles measuring 2-6 mm. The COCP group had significantly fewer antral follicles measuring ≥ 6 mm (P < 0.001) and had significantly smaller ovaries (P < 0.001), which also had lower vascular indices than the control group (P < 0.05). While serum FSH, LH and E2 levels were significantly lower in the COCP group (P < 0.05), there was no significant difference in serum AMH levels between the two groups. CONCLUSIONS Prolonged use of COCP suppressed pituitary gonadotropins and antral follicle development beyond 6 mm, but had no effect on levels of serum AMH and number of small antral follicles.

Abstract
Purpose To investigate potential indicators of in vitro fertilization (IVF) treatment outcome for female infertility patients aged ≥ 40 years based on the clinical course. Methods We retrospectively examined results of 111 female infertility patients aged ≥ 40 years undergoing IVF treatment. We investigated the relationship between treatment cycle cancellation and the final outcome of IVF treatment in female infertility patients aged ≥ 40 years. Results A total of 44 pregnancies were achieved. Overall pregnancy rate per initiated treatment cycle was 12.1%, and 24 spontaneous abortions occurred (54.5%). No woman aged ≥ 45 years achieved pregnancy. No patients conceived after 10 treatment cycles while 42 (11.5%) oocyte pick-up cycles and 120 (33.0%) embryo transfer cycles were canceled. Investigation of correlation with treatment cycle cancellation revealed that patients who experienced embryo transfer cancellation had a high spontaneous abortion rate while only a few patients who experienced oocyte pick-up cancellation achieved pregnancy and even fewer achieved a successful outcome. Conclusions Our study suggests that, in addition to patient age and number of treatment cycles, cancellation of treatment cycle also provides another useful indicator for pregnancy outcome.

Abstract
BACKGROUND Studies in macaques have indicated that androgens have some synergistic effects with FSH on folliculogenesis. This study investigated the usefulness of pretreatment with transdermal testosterone in low-responder IVF patients. METHODS Randomized clinical trial including 62 infertile women who had a background of the first IVF treatment cycle cancelled because of poor follicular response. Patients were randomized in two treatment groups in their second IVF attempt. In patients in Group 1 (n = 31), transdermal application of testosterone preceding standard gonadotrophin ovarian stimulation under pituitary suppression was used. In Group 2 (n = 31 patients), ovarian stimulation was carried out with high-dose gonadotrophin in association with a minidose GnRH agonist protocol. The primary end-point was the incidence of low-responder patients. The main secondary outcome was the incidence of patients reaching ovum retrieval. RESULTS The percentage of cycles with low response was significantly lower in Group 1 than in Group 2 (32.2 versus 71% 95% confidence interval for the difference, 15.7-61.6; P < 0.05). The number of patients with ovum retrieval tended to be higher in Group 1 than in Group 2 (80.6 versus 58.1% P = 0.09), the difference reaching statistical significance (81.2 versus 41.1%; P < 0.05) when only patients having normal basal FSH levels (16 and 17 patients in Groups 1 and 2, respectively) were considered. CONCLUSIONS Pretreatment with transdermal testosterone may improve the ovarian sensitivity to FSH and follicular response to gonadotrophin treatment in previous low-responder IVF patients. This approach leads to an increased follicular response compared with a high-dose gonadotrophin and minidose GnRH agonist protocol.

Abstract
As a result of temporary social trends, many women elect to postpone their first pregnancy to a later stage in life. A large part of this population will be infertile by the time they opt to conceive, mainly because of a decreasing ovarian reserve and low oocyte quality resulting from age. Aging oocytes have been widely suggested to be the major cause for the decline in fertility. In a subfertile population, the availability of an accurate screening test of ovarian reserve would provide a valuable means of predicting the chances of pregnancy and live birth with or without treatment and selecting an optimal dose of ovarian stimulation where treatment using ovarian stimulation is planned. The following hormonal markers and ultrasound parameters have been used to attempt to estimate ovarian reserve and predict those with a poor chance of success in assisted reproductive techniques: age; concentrations of follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, inhibin, anti-Müllerian hormone; ovarian volume, ovarian antral follicle count; and ovarian biopsy. Further studies have introduced the use of dynamic tests-using gonadotropin-releasing hormone agonist, FSH, or clomiphene citrate-to assess ovarian function. The use of a wide range of tests suggests that no single test provides a sufficiently accurate result. But the simultaneous evaluation of a combination of tests could be used as a marker of diminished ovarian reserve and a sensitive predictor of response to ovarian stimulation in patients undergoing in vitro fertilization treatment.

Abstract
BACKGROUND To review the accuracy of multivariate models for the prediction of ovarian reserve and pregnancy in women undergoing IVF compared with the antral follicle count (AFC) as single test. METHODS We performed a computerized MEDLINE and EMBASE search to identify articles published on multivariate models for ovarian reserve testing in patients undergoing IVF. In order to be selected, articles had to contain data on the outcome of IVF in terms of either pregnancy and/or poor response and on the prediction of these events based on a multivariate model. For the selected studies, sensitivity and specificity of the test in the prediction of poor ovarian response and non-pregnancy were calculated. Overall performance was assessed by estimating a summary receiver operating characteristic (ROC) curve, which was compared with the ROC curve for the AFC as the current best single test. RESULTS We identified 11 studies reporting on the predictive capacity of multivariate models in ovarian reserve testing. All studies reported on the prediction of poor ovarian response, whereas none reported on the occurrence of pregnancy. The sensitivity for prediction of poor ovarian response varied between 39% and 97% and the specificity between 50% and 96%. Logistic regression analysis indicated that cohort studies provided a significantly better discriminative performance than case-control studies. As cohort studies are superior to case-control studies, further analysis was limited to the cohort studies. For the cohort studies, a summary ROC curve could be estimated, which had a shape similar to that previously made for the AFC. CONCLUSIONS The accuracy of multivariate models for the prediction of ovarian response in women undergoing IVF is similar to the accuracy of AFC. No data are available on the capacity of these models to predict pregnancy, let alone live birth. On the basis of these findings, the use of more than one single test for the assessment of ovarian reserve cannot currently be supported.

Abstract
BACKGROUND The presence of a wide range of tests of ovarian reserve suggests that no single test provides a sufficiently accurate result. Many tests are used without reference to an evidence base. So far, individual studies conducted on these tests are too small to give precise estimates of prognostic accuracy. OBJECTIVES To systematically assess the accuracy of the available tests of ovarian reserve in terms of prediction of fertility outcomes. SEARCH STRATEGY The search will be conducted using the name of the respective index test being studied (as listed on the MESH database), if more than 2000 citations are listed, 'ovary' and or 'ovarian', 'fertility' and or 'reserve' will be combined with the original search term as required. Studies of the accuracy of tests of ovarian reserve will be obtained without language restrictions from 1980 to 2005 using the following electronic databases and Ovid software: MEDLINE, EMBASE, PUBmed, Biological extracts, Pascal, Cochrane Library (CDSR, DARE, CCTR, HTA), Best Evidence databases, SCISEARCH, Conference Proceedings (ISI Proceedings, Healthstar, Current Contents, Science Citation Index, Cancerlit and Econlit and NHS Economic Evaluation database. The National Research Register, the Medical Research Council's Clinical Trials Register, MEDION, DARE, and the US Clinical Trials register. SELECTION CRITERIA Studies will be selected if accuracy of tests are compared with a reference standard and include data that can be abstracted into a two-by-two table to calculate sensitivity and specificity. The studies to be included in this review will examine one of the following index 'tests' within a study population of women undergoing assisted reproductive technology: * Clinical variables--age, history of cancelled cycles. * Basal blood tests--follicle-stimulating hormone (FSH), lutenising hormone (LH), FSH:LH ratios, estradiol (E(2)), inhibin A and B, progesterone (P(4)), P(4):E(2) ratios, antimullerian hormone, testosterone, vascular endothelial growth factor, insulin-like growth factor-1:insulin-like growth factor binding protein-1 ratios. * Dynamic tests--clomiphene citrate challenge test, gonadotropin analogue stimulating test, exogenous FSH ovarian reserve test. * Ultrasound tests-antral follicle count, ovarian volume, ovarian stromal peak systolic velocity, including waveform and pulsatility index, ovarian follicular vascularity. * Histology--ovarian biopsy. Data collection and analysis Two independent reviewers will perform quality assessment and data extraction. Prognostic accuracy will be determined by calculating positive and negative likelihood ratios for the following outcomes or reference standards: live birth, ongoing pregnancy, clinical pregnancy, biochemical pregnancy, embryos available for transfer, eggs obtained at oocyte retrieval, cycles cancelled prior to oocyte retrieval. Main results and conclusions N/A.

Abstract
The use of gonadotrophins for the treatment of infertility began in the 1930s following early work on the pituitary-ovarian axis and the discovery of FSH and LH. The technological development of pharmaceutical gonadotrophins over the last 60 years has shown improvements in specific activity, purity, degradation and detection of impurities. Throughout these pharmaceutical developments the gonadotrophin content of both urinary and recombinant preparations has been assessed using an animal in-vivo bioassay. This paper reviews the manufacturing history of recombinant human FSH (r-FSH) and follitropin-alfa filled-by-mass (FbM), and evaluates the impact of introducing a pharmaceutical product that is formulated and assayed by a physicochemical method for r-FSH protein content. This consistent gonadotrophin preparation offers the opportunity to reconsider protocols of induction in a new light, deciding the daily amount of r-FSH in relation to specific clinical parameters such as the mean ovarian volume (MOV), basal FSH concentration and body mass index (BMI). Preliminary data on the application of the formula 'basal FSH x BMI/MOV x (5.5/75)' gave interesting results as a new method to standardize the induction therapy. A formula is proposed for deciding the first 5 days of drug administration.

Abstract
BACKGROUND Treatment of poor-responder patients to controlled ovarian stimulation for assisted reproduction, who have normal basal FSH concentrations, is one of the most difficult challenges in reproductive medicine. This study investigated the usefulness of testosterone pretreatment in such patients. METHODS Prospective, therapeutic, self-controlled clinical trial including 25 consecutive infertile patients who had a background of the first and second IVF treatment cycle cancellations due to poor follicular response, in spite of vigorous gonadotrophin ovarian stimulation and having normal basal FSH levels. In the third IVF attempt, all patients received transdermal testosterone treatment (20 microg/kg per day) during the 5 days preceding gonadotrophin treatment. RESULTS Twenty patients (80%) showed an increase of over fivefold in the number of recruited follicles, produced 5.8+/-0.4 (mean+/-SEM) oocytes, received two or three embryos and achieved a clinical pregnancy rate of 30% per oocyte retrieval. There were 20% cancelled cycles. CONCLUSION Pretreatment with transdermal testosterone may be a useful approach for women known to be low responders on the basis of a poor response to controlled ovarian stimulation but having normal basal FSH concentrations.

Abstract
In vitro maturation of oocytes (IVM) has been developed as a treatment option for subjects with good prognosis in assisted reproduction. We present successful IVM treatment in connection with a woman from whom low numbers of embryos were obtained after repeated failed conventional IVF cycles. A 35 year old woman, after 5 years infertility and two intrauterine insemination and three conventional IVF cycles, underwent first an IVM cycle with low dose FSH stimulation, and after failure, another natural IVM cycle. Three oocytes were obtained. After 36 h of IVM the oocytes had reached metaphase II stage, and fertilization using ICSI resulted in one 4-cell stage embryo, which was transferred 2 days later. The result was an uneventful pregnancy and birth of a healthy female infant weighing 4150 g. IVM may be an option for women from whom only low numbers of oocytes are obtained after gonadotrophin stimulation.
