RESUMO
Many risk factors can potentially influence sperm quality. Telomeres confer stability on the chromosome and their dysfunction has been implicated in conditions such as cancer, aging, and lifestyle. The impact of lifestyle on sperm cell telomeres is unclear. The objectives of this study were to evaluate the impact of lifestyle behaviors on telomere length in sperm and to follow the correlation with pregnancy outcomes in patients undergoing in vitro fertilization (IVF). In this prospective observational study, sperm was analyzed for telomere length (TL). Men were asked to report lifestyle behaviors including occupation (physical or sedentary), smoking duration and amount, physical activity, dietary habits, and where they keep their cellular phone (bag, pants, or shirt pocket). Correlations among semen analysis, TL, men's habits, and embryo quality and pregnancy outcomes were evaluated. Among 34 patients recruited, 12 had longer TL and 13 shorter TL. Sperm motility was negatively correlated with TL (Pearson correlation = -.588, p = .002). Smoking adversely affected native sperm motility (53% motility in nonsmokers vs. 37% in smokers; p = .006). However, there was no significant impact on TL. The group with longer telomeres demonstrated significant association with healthy diet (10/12 vs. 6/13; p = .05) and a trend toward more sports activity, weekly (16/84 vs. 7/91; p = .04) compared with the shorter telomeres group. This study suggests that lifestyle, healthy diet, and sports activity are associated with long telomeres in sperm. Sperm quality is also influenced by patients' habits. The study strongly recommends maintaining a healthy lifestyle to preserve general health and fertility.

This paper aims to study the efficacy and safety of diode laser hysteroscopic metroplasty for dysmorphic uterus and the impact on reproductive outcomes. This is a retrospective, single-center pilot study with prospective follow-up. The study was performed at a university-affiliated, tertiary hospital. From February 2018 to February 2020, all nulliparous women with a 3D ultrasound diagnosis of T-shaped or Y-shaped dysmorphic uterus and diagnosis of infertility, recurrent implantation failure, or recurrent pregnancy losses were referred for hysteroscopic metroplasty. Diode laser hysteroscopic metroplasty was performed under general anesthesia in an ambulatory setting. Main outcome measures included operative time, complications, hysteroscopic appearance of the cavity in a follow-up hysteroscopy, and reproductive outcomes in terms of pregnancy and live birth. A total of 25 infertile women with mean duration of infertility of 56.6 ± 36.1 months underwent hysteroscopic metroplasty. No complications were reported, and subsequent 3D ultrasound and follow-up hysteroscopic appearance were satisfactory in all cases. Maximum follow-up was 32 months (mean ± standard deviation 11.5 ± 9.2 months). Fifteen nulliparous women returned for fertility treatments in our institute, among whom nine conceived (60% pregnancy rate). The rate of deliveries and ongoing pregnancies (pregnancies beyond 24 weeks of gestation) was 78% (7/9), with six successful liveborn deliveries at 36-38 weeks and one ongoing pregnancy. One had spontaneous abortion at week 19 and one had a spontaneous abortion at week 7. Hysteroscopic metroplasty in an ambulatory setting, using diode laser, is a safe and effective procedure, improving reproductive outcomes in cases of T-shaped or Y-shaped uterus.

This retrospective study was conducted to determine whether using oral dydrogesterone (DYD) instead of micronized vaginal progesterone (MVP) in frozen embryo transfer (FET) cycles affects pregnancy outcomes. Women undergoing autologous FET in an academic fertility center were evaluated. Uses of 10 mg TID oral DYD or MVP for patients treated in FET cycles (artificial and ovulatory cycle, separately) were compared. The main outcome measure was live birth rates in each group. The study analyzed 599 cycles that occurred from January 2018 through December 2019. Chemical and clinical pregnancy rates were comparable between DYD vs. MVP groups (41.6% vs. 38.1%; P = 0.44 and 36.7% vs. 31.4%; P = 0.18, respectively). The ongoing pregnancy and delivery rates (29% vs. 22%, P = 0.06), as well as abortion rate (12.3% vs. 15.8%, P = 0.2), were comparable between the two groups. In a case-control sub-analysis of artificial FET cycles, we found comparable results between the two modes of luteal support. Similarly, results were comparable in ovulatory cycles using these medications for luteal support. Chemical and clinical pregnancy rates were comparable with DYD vs. MVP, in artificial FET (33.7% vs. 34.8%; P = 0.89 and 27.7% vs. 27.5%; P = 1), and in ovulatory FET (46.5% vs. 43.9%; P = 0.71 and 42.3% vs. 38.2%; P = 0.53), respectively. Our results indicate that in FET, pregnancy outcomes with oral DYD were not inferior to those with MVP.

OBJECTIVE: To evaluate the relationship between endometrial thickness measured before embryo transfer, and pregnancy outcomes in frozen-thawed embryo transfer (FET). METHODS: We retrospectively analyzed outcomes of all consecutive FET cycles, from January 2012 to August 2018. Based on ROC analysis for endometrial thickness, we found 8 mm was a reliable cutoff point to predict pregnancy prior to embryo transfer. Accordingly, the cycles were divided into Group A: cycles with endometrial thickness ≤ 8 mm and Group B: > 8 mm. RESULTS: Group A included 485 FET cycles and group B included 626 cycles. Compared with group A, Group B had significantly higher chemical and clinical pregnancy rates (30.3 vs. 24.6%; p = .046, and 24.0 vs. 18.6%; p = .036), respectively. In multivariate analysis, endometrial thickness and the protocols used were the only parameters influencing the chance to achieve pregnancy, with odds ratio 1.54 (95%CI 1.07-2.22, p = .019) for the endometrium and odds ratio 1.95 (95%CI 1.31-2.9; p = .001) to the protocol used. Endometrial thickness might predict crown-rump length (CRL) discordancy with odds ratio 4.61 (p = .001; 95% CI 1.42-14.92). Compared with group B, Group A had more cases of overt discordancy (13.3 vs. 4%; p = .016). CONCLUSIONS: For patients undergoing FET cycles, endometrial thickness and treatment protocol may predict the chemical and clinical pregnancy rates, as well as CRL discordancy. SUMMARY: Endometrial thickness and preparation improved pregnancy rate in FET cycles and significantly greater crown-rump length discordancy was observed with thinner endometria.

The presence of Degenerated Oocyte (DEG) was mostly described after intracytoplasmic sperm injection (ICSI), with fewer reports on DEG at the time of ovum pick-up (OPU). This study aims to assess morphokinetics of embryos cultured in a time-lapse incubator and compare cohorts with and without DEG at OPU. In a retrospective cohort study from January 1, 2016 until September 31, 2017 a total of 399 IVF/ICSI cycles and 2980 embryos were evaluated. In 81 of 399 cycles at least one DEG oocyte was observed at the time of OPU. The remaining 318 cycles with no DEG oocyte were compared as a control group. In the DEG group, significantly more oocytes were collected per patient (12.9 ± 7.2 vs. 10.1 ± 6.1. P < 0.001). Fertilization rate, pregnancy and clinical pregnancy rates were comparable between the two groups, however, the morphokinetics and developmental scores of the embryos were significantly worse in the DEG group, (KID 3.4 ± 1.6 vs. 3.2 ± 1.6 P = 0.002 and ESHRE 1.5 ± 1.1 vs. 1.4 ± 1.0 P = 0.046). Significantly more patients achieved top-quality embryos in the NON DEG group (58.8% vs. 53.0%, P = 0.03), however, comparable delivery rate was achieved in both groups. In the DEG group, the frequency of DEG oocyte per cycle was negatively correlated with pregnancy rate. GnRH agonist protocol and the 17-20G needle used for OPU were significant predictors for the presence of DEG oocyte at OPU. In conclusions DEG oocyte may negatively affect IVF outcome, however, younger patients, and significantly more oocytes collected in the DEG group compensate for the IVF results.

To examine the effect of serum follicle-stimulating hormone (sFSH) level, body-mass index (BMI) and smoking on Testicular Sperm Extraction-Intracytoplasmic Sperm Injection (TESE-ICSI), and pregnancy outcomes.In this retrospective study, data were extracted from files of 52 azoospermic men who underwent TESE and in-vitro fertilization (IVF)-ICSI in our IVF unit. Demographic information, treatment cycle follow-up and pregnancy outcomes were collected.Fifty-two patients underwent 79 TESE due to azoospermia in 143 IVF cycles. Smoking was found to significantly affect sperm motility in TESE specimens before freezing (45.5% vs 14.8%; Pâ<.001); however, this finding did not influence the pregnancy rate. Male FSH was inversely correlated with testicle volume (r = -0.595, Pâ<.0001). Body weight did not affect semen parameters after TESE or ICSI outcomes.Among azoospermic patients with extremely poor sperm quality, male BMI, male FSH or smoking did not have an adverse effect sperm parameters or pregnancy and delivery rates.

Our study aimed to determine whether mid-luteal serum P concentrations can serve as a predictive factor for in vitro fertilization (IVF) outcomes and whether increasing P dosage for patients with low levels at mid-luteal phase may improve pregnancy rates. It was a prospective, randomized controlled study. A total of 146 patients undergoing IVF treatment were prospectively enrolled and received routine luteal phase support (LPS) regimen of Endometrin® (progesterone) 200 mg/day. Serum P levels were measured 7 days after embryo transfer (ET). Considering a cutoff level of 15 ng/ml on this day, patients with higher levels continued the same dosage until pregnancy test (control group). Patients with lower levels were randomly allocated to continue Endometrin® 200 mg/day (Group A) or to increase Endometrin® dosage to 300 mg/day (Group B). The Main Outcome Measures were pregnancy rates. Both biochemical and clinical pregnancy and live birth rates were comparable between all groups regardless of P level on day 7 of luteal phase and regardless of dose adjustment. ROC analysis determined that mid-luteal P levels of 17 ng/ml can be a better predictor of cycle outcome. In conclusion raising the P dose at mid-luteal phase to 300 mg daily did not improve cycle outcomes.

PURPOSE: Highly purified Human Menopausal Gonadotropins (hp-hMG) and recombinant FSH (rFSH) are widely used in assisted reproductive technology (ART). The aim of this study was to compare ART results of the two preparations in GnRH antagonist cycles. METHODS: In this retrospective cohort study, IVF antagonist cycles performed from 2011 through 2013 were reviewed. There were 508 antagonist cycles: 320 stimulated with rFSH and 188 with hp-hMG. For every hp-hMG, two rFSH were matched for patient's age and infertility diagnosis. Subgroup analysis of patients younger and older than 35 was done as well. RESULTS: Both treatments were resulted in comparable pregnancy and live birth rates. However, cumulative pregnancy rates were higher for the rFSH group. In the matching analysis, the rFSH group had more mature oocytes and more embryos while using lower doses of gonadotropins. Pregnancy, cumulative pregnancy rates, and live birth rates were comparable. In the subgroup analysis, young patients in the rFSH group had better cycle outcomes compared with those in the hp-hMG group. CONCLUSION: In antagonist protocol, different gonadotropin products are equally effective. The choice of one or the other should depend on the availability, convenience of use, and cost.

Antral follicle count (AFC) has been shown to be a reliable marker for ovarian reserve. The aims of this study were to create an age-related normogram for AFC in infertile women with polycystic ovary syndrome (PCOS) and to compare age-related decline in AFC between infertile women with and without PCOS. A retrospective cohort study was conducted. Of a total of 4956 women, 619 women fit criteria for PCOS. In those with PCOS, there were large variations in the AFC between the 10th and 90th percentiles in all age groups. The rate of decline in AFC among women with PCOS was linear, while in those with non-PCOS, it was exponential until 30 years of age, and then became similar to that of PCOS. The rate of follicle loss per year was significantly slower in PCOS women compared with that in non-PCOS women. In both groups, the fastest period of follicle loss was between the ages of 18 and 30. The average follicle loss was 0.8 follicles/year in PCOS women and 1.7 follicles/year in those without PCOS (P<0.001). This study concludes that age-related decline in AFC among women with PCOS is slower than in those without PCOS. Antral follicle count (AFC) has been shown to be a reliable marker for ovarian reserve. The aims of this study were to create an age-related normogram for AFC in women with polycystic ovary syndrome (PCOS), and to compare age-related decline in AFC between women with and without PCOS. A retrospective cohort study was conducted. All patients underwent a baseline transvaginal ultrasound that was performed on day 2-4 of the menstrual cycle. The total number of antral follicles of 2-9mm in diameter was recorded. Of total 4956 women, 619 women fit criteria for PCOS. In those with PCOS, there were large variations in the AFC between the 10th 90th percentiles in all age groups. The rate of decline in AFC among women with PCOS was linear; while in those with non-PCOS, it was exponential until 30 years of age, and then became similar to that of PCOS. The rate of follicle loss per year was significantly slower in PCOS women compared with that in non-PCOS women. In both groups, the fastest period of follicle loss was between the ages 18-30 years. The average follicle loss was 0.8 follicles/year in PCOS women and 1.7 follicles/year in those without PCOS (P<0.001). We have concluded that age-related decline in AFC among women with PCOS is slower than in those without PCOS. Further studies are needed to determine if the AFC normogram in women with PCOS could be clinically relevant to select the optimal gonadotrophin dose for ovulation induction.

OBJECTIVE: To determine whether high luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratios have a clinical impact on women with polycystic ovary syndrome (PCOS) undergoing in vitro maturation (IVM) treatment. STUDY DESIGN: Women with PCOS who underwent IVM treatment were divided into those with LH/FSH ratio > 1.5 and LH/FSH 0.5-1.5. We analyzed baseline characteristics of the patients, number of oocytes retrieved, number of mature oocytes, and pregnancy rates. RESULTS: Women with LH/FSH ratio of > 1.5 had higher basal serum testosterone (2.2 vs. 1.4, p < 0.005, CI 0.1-1.0) and estradiol (188.7 +/- 16.2 vs. 143.7 +/- 6.9, p < 0.01, CI 23-96). The antral follicle count (AFC) was also higher in the patients with high LH/FSH (46.2 +/- 3.5 vs. 32.9 +/- 1.3, p < 0.001, CI 7-21). The total number of retrieved oocytes and number of mature oocytes was also significantly higher in women with LH/FSH ratio of > 1.5 than in those with a lower ratio. However, the pregnancy rate in women with LH/FSH ratio of > 1.5 (16.7%) was significantly lower than in those with a ratio of 0.5-1.5 (40.4%), p < 0.05, odds ratio 0.32. CONCLUSION: PCOS patients with LH/FSH ratio of > 1.5 had higher basal testosterone, E2, and AFC but decreased pregnancy rate. This could be due to the deleterious effect of LH on folliculogenesis and endometrial receptivity.

OBJECTIVE: Our aim was to compare treatment outcome following in vitro maturation (IVM) compared with IVF in patients with polycystic ovarian syndrome (PCOS). STUDY DESIGN: Retrospective evaluation of treatment in women with PCOS who underwent IVM (108) and IVF (108). RESULTS: We found a significant difference in outcome between IVM and IVF, with an increase in the number of mature oocytes derived (10.5 ± 6.5 vs. 15.3 ± 8.8, p<0.0001) and the cleavage rate (92.4 ± 13.0 vs. 95.2 ± 11.7, p=0.03) in IVM cycles. Due to the lower implantation rate (16.1% vs. 21.6%, p=0.07) we tend to transfer more embryos in the IVM group (3.4 ± 0.8 vs. 2.8 ± 1.0, p<0.0001), but the multiple pregnancy rate in that group was not higher. Importantly, the delivery rate was similar in both groups (26.8% vs. 25%). We also report a yearly change in the success rate of IVM during this period. CONCLUSIONS: IVM treatment for PCOS patients may be a valid alternative treatment to IVF with the advantage of eliminating the risk of OHSS and reducing the cost of medication, whilst maintaining high clinical pregnancy rate.

OBJECTIVE: To evaluate the value of intrauterine insemination (IUI) in controlled ovarian hyperstimulation (COH) among couples with polycystic ovary syndrome (PCOS) and normal semen analysis. DESIGN: Retrospective cohort study. SETTING: University teaching center. PATIENTS: PCOS couples with normal semen analysis that underwent COH with IUI or timed intercourse (TIC). INTERVENTION: COH with clomiphene citrate, letrozole or gonadotropins with or without IUI. MAIN OUTCOME MEASURES: Clinical pregnancy rates. RESULTS: Of a total 265 cycles, 151 cycles were with IUI and 114 others with TIC. No significant difference was found in the overall pregnancy rates between the TIC group (17.5%) and the IUI group (16.6%). Analysis of pregnancy rates according to the type of COH treatments did not demonstrate the advantages of IUI over TIC. CONCLUSION: Compared to timed intercourse, IUI does not increase the pregnancy rate in couples with PCOS and normal semen analysis treated with COH.

OBJECTIVE: To compare the treatment outcomes in in vitro maturation (IVM) cycles primed with human menopausal gonadotropin with those for pure IVM cycles in patients with polycystic ovary syndrome. DESIGN: Prospective observational. SETTING: University-based tertiary medical center. PATIENT(S): Patients undergoing IVM cycles (primed IVM, 47; pure IVM, 118). INTERVENTION(S): IVM treatment with and without human menopausal gonadotropin stimulation. MAIN OUTCOME MEASURE(S): Pregnancy rates. RESULT(S): The clinical pregnancy rate demonstrated a tendency toward improvement in the primed IVM group (53.1% vs. 43.6%, 20.1% vs. 14.0% and 40.4% vs. 30.8%, [corrected] respectively) with better implantation and delivery rates (20.1% versus 14.4%; 95% confidence intervals 1.0-3.06 and 40.4% versus 24.6%; 95% confidence intervals 0.1-0.8, respectively). We found no significant difference in pure IVM compared with primed IVM in the number of eggs collected, size of leading follicle, fertility rate, cleavage rate, and the number of embryos transferred. Total mature eggs and maturation rate were significantly higher in the group of pure IVM (11 ± 2.1 versus 8.7 ± 0.5 and 68.5% ± 17.5% versus 60.9% ± 0.4%, respectively). Importantly, the endometrial thickness was significantly improved in primed IVM cycles (7.9 ± 1.9 mm versus 7.1 ± 0.8 mm), possibly leading to better implantation and pregnancy rates. CONCLUSION(S): Patients who fail to demonstrate endometrial or follicular growth during IVM cycles may benefit from gonadotropin priming during the same cycle.

OBJECTIVE: To evaluate the effect of body mass index (BMI) on in vitro maturation (IVM) outcomes in women with polycystic ovaries. DESIGN: Retrospective, cohort study. SETTING: Tertiary IVF unit. PATIENT(S): One hundred thirteen women with polycystic ovaries. INTERVENTION(S): One hundred sixteen cycles of IVM. Patients were divided into subgroups according to their BMI: underweight, normal weight, overweight, obese, and morbidly obese. We evaluated the effects of BMI on the number of oocytes matured in vivo, maturation rate in vitro, fertilization and cleavage rates, number of embryos transferred, implantation rates, pregnancy rates, and delivery rates. MAIN OUTCOME MEASURE(S): Pregnancy rate and delivery rate. RESULT(S): The number and quality of oocytes among women with different BMIs were similar. There was no significant difference in the endometrial thickness and rates of implantation, pregnancy, and delivery among women with different BMIs. The pregnancy rate in underweight women was 50%, normal weight 47.9%, overweight 29.1%, obese 27.2%, and in morbidly obese women was 30.7%. The miscarriage and delivery rates were also similar. CONCLUSION(S): The results of IVM are independent of BMI.

PURPOSE: To explore four areas of controversy: the benefits of gonadotropin priming, benefits and timing of hCG trigger as well as the ideal protocols for endometrial preparation and luteal support. METHODS: A literature review was performed to explore the current evidence RESULTS: Current evidence suggests that Gonadotropin priming in combination with hCG prior to collection benefits patients with normal ovaries. In PCOS patients 10,000 IU hCG 38 h before retrieval increases the total number and rate of oocyte maturation. Gonadotropin priming may also benefit PCOS patients. The ideal timing of hCG trigger appears to be when the leading follicle is 10-12 mm. Sparse data exists regarding luteal support protocols. CONCLUSIONS: There is still a need for well-designed studies to establish ideal methods for oocyte priming, timing of retrieval, endometrial preparation and luteal support. Further studies must incorporate both clinical and basic science principles of ovarian, follicular and endometrial physiology.

PURPOSE: To investigate whether there is additional value for saline instillation sonohysterography (SIS) as a routine screening tool when baseline transvaginal sonography (TVS) is normal. METHODS: Two-hundred ninety four infertility patients underwent baseline TVS and were categorised according to the results. TVS findings were negative in study group (n = 124) and positive (any abnormalities) in control group (n = 170). All the patients were further investigated by SIS. Hysteroscopy was performed whenever SIS results were suspicious. Our main outcome measure was accuracy of SIS in detecting intracavitary lesions using pathology reports as gold standard. RESULTS: In the study group, out of 124 SIS tests, 13 (10.4%) showed positive findings and were further investigated by hysteroscopy. Three out of the 13 (23.0%) had subsequent positive hysteroscopy findings, however, no (0.0%) abnormality was found on pathologic examination. In the control group, out of 170 SIS tests, 62 (36.4%) showed positive findings, and were further investigated by hysteroscopy. Forty-two cases out of the 62 (67.7%) had subsequent positive hysteroscopic findings. Pathological examination was positive in 35 out of the 42 (83.3%) positive hysteroscopies. CONCLUSION: Routine SIS for patients with normal TVS did not contribute additional findings. However, in patients with any suspicious findings on TVS (including extracavitary lesions), SIS was beneficial.

OBJECTIVE: To produce age-related normograms for antral follicle count in an infertile population without polycystic ovaries. DESIGN: Retrospective cohort analysis. SETTING: University teaching center. PATIENT(S): Eighteen hundred sixty-six infertile patients. INTERVENTION(S): Baseline transvaginal ultrasound examination between days 2 and 4 of the menstrual cycle. MAIN OUTCOME MEASURE(S): Correlation between age and different percentiles of antral follicle count. RESULT(S): The age-related normogram for the 3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentile of antral follicle count showed a biphasic mode of antral follicle count decline with two different rates of antral follicle count loss: a steep-slope phase (high rate of antral follicle count loss) and a moderate-slope phase (restrained rate of antral follicle count losses). In the low antral follicle count percentiles (3rd, 10th, 25th), the phase of high loss rate of follicles preceded the phase of slow loss rate, whereas in the high antral follicle count percentiles (75th, 90th, 97th) the opposite was found. CONCLUSION(S): Age-related normograms in infertile women without polycystic ovaries demonstrate a biphasic pattern of decreased antral follicles. These normograms could provide a reference guide for the clinician in consulting with women with infertility. However, future validation with longitudinal data is still needed.

In vitro fertilization and embryo cryopreservation are regarded as the only established method for the preservation of fertility in female cancer patients. However, a possible delay in the treatment of cancer and exposure to supraphysiologic estrogen levels caused by ovarian stimulation raise concerns for patients and physicians. In vitro maturation avoids treatment delay or exposure to increased estradiol levels associated with in vitro fertilization. In vitro maturation combined with embryo or oocyte vitrification provides options that have been unavailable earlier, such as immature oocyte collection in the luteal phase, for some patients and improves the services provided by a fertility preservation program.

Unstimulated in-vitro maturation (IVM) cycles are considered for fertility preservation in breast cancer due to avoidance of ovarian stimulation and shortened time to oocyte retrieval. This study evaluated the efficacy of this approach in a retrospective cohort analysis of 66 patients with breast cancer. Immature oocytes were collected and matured in vitro and then either vitrified or fertilized and preserved as vitrified embryos. In group 1 (vitrified oocytes, n=35), the average number of oocytes retrieved was 11.4 ± 8.8, the maturation rate was 64.2% and an average of 7.9 ± 6.6 oocytes were vitrified per patient treated. The median duration from the first evaluation to oocyte retrieval was 8 days. In group 2 (vitrified embryos, n=31) the average number of oocytes retrieved was 9.7 ± 6.4, the maturation rate was 53.2% and an average of 5.8 ± 2.7 mature oocytes were available for fertilization/patient. The fertilization rate was 77.8%, resulting in 4.5 ± 2.7 vitrified embryos/patient. The median duration from the first evaluation to oocyte retrieval was 13 days. Calculated pregnancy rates per vitrified oocyte and embryo were 3.8% and 8.1%, respectively. IVM can be considered a useful option for fertility preservation in breast-cancer patients.

We compared the response of operated and nonoperated ovaries to gonadotropin stimulation in 38 women who had had excision of ovarian endometrioma. The antral follicle count, numbers of dominant follicles, and number of oocytes collected in the operated ovaries were significantly lower than in the nonoperated ovaries suggesting reduced ovarian reserve after excision of ovarian endometrioma.
