RESUMEN

Circulating anti-müllerian hormone (AMH) and antral follicle count (AFC) are the best predictors of IVF outcomes. However, in extreme low AMH range especially for young patients, AMH prediction power loose its specificity to give real idea of pregnancy chance with IVF treatments and good prognosis of an extremely reduced ovarian reserve and expected poor response. Indeed, this retrospective study was conducted to evaluate IVF outcomes in patients following IVF-ICSI program with extremely low AMH levels (≤0.4 ng/ml; n = 390) compared to those presenting normal AMH range (1.3-2.6 ng/ml; n = 352) considered as control group. As expected, number of oocytes retrieved per patient, and embryological outcomes were significantly lower in the extremely low AMH levels group compared to control. Moreover, it was same trend concerning clinical outcomes but we have to note that even in extreme low AMH, patients could reach ineligible satisfying clinical pregnancy rate compared to control (17% vs 41%). For patients younger than 35 years, clinical pregnancy rate improved to 27%. Women with extreme low AMH values and especially younger ones, still have reasonable chances of achieving pregnancy, highlighting the default view of this category generally excluded from IVF program.

RESUMEN

Luteal estradiol pretreatment (LEP) to IVF protocols designed to improve follicle synchronization and retrieval of mature oocytes. We conducted a retrospective study including women undergoing IVF program who were given a course of 4 mg oral estradiol-17ß daily from day 20 of the same cycle until day 1 of their next cycle before starting an antagonist protocol, forming LEP-group but control-group started on day 3 a stimulation without pretreatment. A total is divided into 2 groups (poor (group 1, n = 148) and normal responders (group 2, n = 244)). Our findings show for group 1 a significant decrease in cancelation rate (3% vs 14%) and a significant improvement in clinical outcomes (clinical pregnancy per transfer and live birth rate respectively: 47% and 44% vs 12% and 11%). For group 2, this pretreatment could increase significantly the maturation rate (77% vs 68%). The rate of frozen embryos was improved in both groups: (group 1: 11% vs 2% and group 2: 53% vs 41%). LEP increases the frozen embryos rate whatever the nature of the ovarian response, but especially for normal responders it coordinates follicular recruitment increasing the maturation rate. In the case of poor responders, it affects positively clinical outcomes decreasing the canceled cycles.

RESUMEN

This study assessed sperm quality declining on relation to paternal age and its impact on in vitro fertilization (IVF) outcomes in order to estimate the APA (Advanced Paternal Age) cutoff. For this, 83 couples undergoing IVF treatment for male factor infertility were enrolled. The women age was ≤39 years, whereas the men were divided in two groups: APA (n = 41; age ≥ 40 years) and young (Y) (n = 42; age < 40 years). Conventional semen parameters (volume, concentration, motility, vitality, and morphology) were analyzed in the collected sperm samples. Furthermore, sperm genome decays (SGD) was assessed by TUNEL assay (DNA fragmentation), aniline blue staining (chromatin decondensation), and fluorescent in situ hybridization (aneuploidy). No significant difference was found concerning the conventional semen parameters between APA and Y groups. Conversely, SGD analysis showed increased DNA fragmentation; chromatin decondensation and sperm aneuploidy rates in the APA group (respectively, 41%, 43%, and 14% vs. 25%, 23%, and 4% in Y group). IVF outcomes also were affected by paternal age as indicated by the rates of cancelled embryo transfers, clinical pregnancy and miscarriage in the two groups APA and Y (29%, 17%, and 60% vs. 10%, 32%, and 42%). Finally, statistical analysis of the results suggests that the age of 40 should be considered as the APA cutoff during ART attempts.

RESUMEN

Implantation failure is a major limiting factor in assisted reproduction improvement. Dysfunction of embryo-maternal immuno-tolerance pathways may be responsible for repeated implantation failures. This fact is supported by immunotropic theory stipulating that maternal immune cells, essentially uterine CD56+ natural killer cells, are determinants of implantation success. In order to test this hypothesis, we applied endometrium immuno-modulation prior to fresh embryo transfer for patients with repeated implantation failures. Peripheral blood mononuclear cells were isolated from repeated implantation failure patients undergoing assisted reproductive technology cycles. On the day of ovulation induction, cells were isolated and then cultured for 3 days and transferred into the endometrium cavity prior to fresh embryo transfer. This immunotherapy was performed on 27 patients with repeated implantation failures and compared with another 27 patients who served as controls. Implantation and clinical pregnancy were increased significantly in the peripheral blood mononuclear cell test versus control (21.54, 44.44 vs. 8.62, 14.81%). This finding suggests a clear role for endometrium immuno-modulation and the inflammation process in implantation success. Our study showed the feasibility of intrauterine administration of autologous peripheral blood mononuclear cells as an effective therapy to improve clinical outcomes for patients with repeated implantation failures and who are undergoing in vitro fertilization cycles.

RESUMEN

The development of in vitro fertilization (IVF) techniques for infertility management has led to the investigation of the proteome of follicular fluid and oocyte. In addition, different markers contributing to oocyte maturation and embryo development potential have been reported in the literature. Different techniques were utilized to analyze whole proteome or single protein markers in follicular fluid and oocytes, particularly in animal models. Data from several studies have generated large amounts of information, however, an ideal profile to predict the best oocytes and embryos suitable for implantation are still to be uncovered. The identification of such profiles and markers from follicular fluid, oocytes and endometrium should help scientists and clinicians develop better strategies to improving clinical outcome of IVF cycles.

RESUMEN

Infertile male patients often exhibit unconventional semen parameters, including DNA fragmentation, chromatin dispersion, and aneuploidy-collectively referred to as sperm genome decay (SGD). We investigated the correlation of SGD to embryo chromosomal abnormalities and its effect on clinical pregnancy rates in patients with advanced maternal age (AMA) (>40 years) who were undergoing intracytoplasmic sperm injection-preimplantation genetic screening (ICSI-PGS). Three groups were assessed: patients with AMA and male partners with normal sperm (AMA-N); AMA patients and male partners presenting with SGD (AMA-SGD); and young fertile female patients and male partners with SGD (Y-SGD). We found a significant increase in embryonic chromosomal abnormalities-polyploidy, nullisomy, mosaicism, and chaotic anomaly rates-when semen parameters are altered (76% vs. 67% and 66% in AMA-SGD vs. AMA-N and Y-SGD groups, respectively). Statistical analysis showed a correlation between SGD and aneuploidies of embryonic chromosomes 13, 16, 21, X, and Y, as well as negative clinical outcomes. Incorporation of molecular sperm analyses should therefore significantly minimize the risk of transmission of chromosomal anomalies from spermatozoa to embryos, and may provide better predictors of pregnancy than conventional sperm analyses. We also demonstrated that an ICSI-PGS program should be implemented for SGD patients in order to limit transmission of chromosomal paternal anomalies and to improve clinical outcome.

RESUMEN

PURPOSE: The use of antioxidants is common practice in the management of infertile patients. However, there are no established guidelines by professional societies on antioxidant use for male infertility. MATERIALS AND METHODS: Using an online survey, this study aimed to evaluate the practice pattern of reproductive specialists to determine the clinical utility of oxidative stress (OS) testing and antioxidant prescriptions to treat male infertility. RESULTS: Responses from 1,327 participants representing 6 continents, showed the largest participant representation being from Asia (46.8%). The majority of participants were attending physicians (59.6%), with 61.3% having more than 10 years of experience in the field of male infertility. Approximately two-thirds of clinicians (65.7%) participated in this survey did not order any diagnostic tests for OS. Sperm DNA fragmentation was the most common infertility test beyond a semen analysis that was prescribed to study oxidative stress-related dysfunctions (53.4%). OS was mainly tested in the presence of lifestyle risk factors (24.6%) or sperm abnormalities (16.3%). Interestingly, antioxidants were prescribed by 85.6% of clinicians, for a duration of 3 (43.7%) or 3-6 months (38.6%). A large variety of antioxidants and dietary supplements were prescribed, and scientific evidence were mostly considered to be modest to support their clinical use. Results were not influenced by the physician's age, geographic origin, experience or training in male infertility. CONCLUSIONS: This study is the largest online survey performed to date on this topic and demonstrates 1) a worldwide understanding of the importance of this therapeutic option, and 2) a widely prevalent use of antioxidants to treat male infertility. Finally, the necessity of evidence-based clinical practice guidelines from professional societies is highlighted.

RESUMEN

OBJECTIVE: To study the effectiveness of a new in vitro maturation (IVM) approach based on heterologous follicular fluid (HFF) and supernatant of cumulus-granulosa cells (CGCs) mimicking the intact follicular microenvironment to rescue immature denuded oocytes (IDOs) of patients with polycystic ovary syndrome (PCOS) whose IVM or IVF outcomes remain poor. DESIGN: Randomized controlled trial. SETTING: University-affiliated private center. PATIENT(S): One hundred fifty-nine IDOs were obtained from 47 patients with PCOS. First, a simple IVM system (S-IVM; 40 IDOs; control group) was compared with different protocols based on the addition of autologous follicular fluid (AFF-IVM; 44 IDOs), HFF (HFF-IVM; 42 IDO), or HFF with CGC isolated from seven women without PCOS and presenting 100% in vivo oocyte maturation (HFF/CGC-IVM; 33 IDOs). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): IVM outcomes were compared among the four groups (S-IVM, AFF-IVM, HFF-IVM, HFF/CGC-IVM); then the vitro and in vivo maturation results (from controlled ovarian stimulation of PCOS patients) were compared for each group. RESULT(S): The HFF/CGC-IVM method gave the best yield of developed blastocysts per IDO compared with S-IVM, AFF-IVM, and HFF-IVM (27% vs. 2%, 2%, and 12%, respectively). The IVM rate with the HFF/CGC-IVM method was even higher than that compared with the in vivo maturation rate (79% vs. 42%), with significant improvement in the cleavage rate (71% vs. 61%). CONCLUSION(S): This adapted IVM system could be used to reach an acceptable result in meiotic competence and competent metaphase II oocytes capable of developing into intact embryos after fertilization and before transfer.
