RESUMO

The protocols commonly used in assisted reproductive technology (ART) consist of long-term embryo culture up to the blastocyst stage after the insemination of all mature oocytes, the freezing of all the embryos produced, and their subsequent transfer one by one. These practices, along with preimplantation genetic testing, although developed to improve the live birth rate (LBR) and reduce the risk of multiple pregnancies, are drawing attention to the possible increase in obstetric and perinatal risks, and adverse epigenetic consequences in offspring. Furthermore, ethical-legal concerns are growing regarding the increase in cryopreservation and storage of frozen embryos. In an attempt to reduce the risk associated with prolonged embryo culture and avoid embryo storage, we have chosen to inseminate a limited number of oocytes not exceeding the number of embryos to be transferred, after two days or less of culture. We retrospectively analyzed 245 ICSI cycles performed in 184 infertile couples with a female partner aged ≥40 from January 2016 to July 2021. The results showed a fertilization rate of 95.7%, a miscarriage rate of 48.9%, and a LBR of 10% with twin pregnancies of 16.7%. The cumulative LBR in our group of couples was 13%. No embryos were frozen. In conclusion, these results suggest that oocyte selection and embryo transfer at the cleaving stage constitute a practice that has a LBR comparable to that of the more commonly used protocols in older women who have reduced ovarian reserve.

RESUMO

OBJECTIVE: To develop and validate a specific simple measure of insulin sensitivity using oral glucose tolerance test (OGTT) values for lean polycystic ovary syndrome (PCOS) women. DESIGN: Retrospective study. SETTING: Gynecologic Outpatient Clinic of University Hospital, affiliated with Unit of Gynecologic Endocrinology. PATIENT(S): Totals of 201 lean and 198 overweight/obese (ov-ob) nondiabetic PCOS patients were retrospectively selected. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): All patients underwent OGTT, euglycemic-hyperinsulinemic clamp, and androgenic and biochemical assays. The predictive performance of each insulin resistance (IR) index was analyzed with the use of receiver operating characteristic (ROC) curves. RESULT(S): Higher correlation coefficients with clamp studies were obtained with the Belfiore Area (RS=0.579) and the homeostasis-model assessment (HOMA)-M120 (RS=-0.576) in lean PCOS patients and with the Sib (RS=0.697) in ov-ob PCOS patients. The best predictive index of IR in lean PCOS was a HOMA-M120 value of ≥12.8 or more (area under the ROC curve [AUC] 92.4%). In the ov-ob PCOS population, the best predictive performance was obtained by a Sib of ≤10.2 or less (AUC 85.7%). CONCLUSION(S): IR should be assessed in all PCOS women, both lean and ov-ob subjects. The HOMA-M120 resulted as a very simple tool, validated specifically for the lean PCOS woman whose cardiometabolic impairment is more frequently misunderstood.

RESUMO

OBJECTIVE: To evaluate the long-term effects of drospirenone (DRSP)/ethinylestradiol (EE) alone, metformin alone, and DRSP/EE-metformin on CD4(+)CD28(null) T lymphocytes frequency, a cardiovascular risk marker, in patients with hyperinsulinemic polycystic ovary syndrome (PCOS). DESIGN: Randomized clinical trial. INTERVENTIONS: Ninety three patients with hyperinsulinemic PCOS were age matched and body mass index matched and randomized to receive a 6 months daily treatment with DRSP (3 mg)/EE (0.03 mg), or metformin (1500 mg), or DRSP/EE combined with metformin. MAIN OUTCOME MEASURES: CD4(+)CD28(null) T-cell frequencies. RESULTS: The DRSP/EE and metformin groups did not show any significant change in the CD4(+)CD28(null) frequency compared to the baseline. Interestingly, a statistically significant decrease in CD4(+)CD28(null) frequency occurred after 6 months of DRSP/EE-metformin (median 3-1.5; P < .01). Of note, this statistically significant association was confirmed after adjusting for baseline values in DRSP/EE-metformin group by analysis of covariance (P < .05). CONCLUSIONS: In women with hyperinsulinemic PCOS, combined therapy with DRSP/EE and metformin may reduce cardiovascular risk.

RESUMO

OBJECTIVE: To evaluate the role of mean ovarian volume (MOV) in the diagnosis of polycystic ovary syndrome (PCOS) during adolescence, and its relationship with metabolic and endocrine parameters. DESIGN: Observational study. PATIENTS: A total of 134 young girls, including 86 adolescents with PCOS and 48 controls, were studied. MEASUREMENTS: During the early follicular phase, a pelvic ultrasound examination was performed to measure the ovarian volume of both ovaries and to calculate the MOV. All subjects underwent hormonal assessment and an ultrasound examination. PCOS subjects were submitted to an oral glucose tolerance test. The homeostasis model assessment for insulin resistance (HOMA-IR) and several insulin resistance indexes were also determined. RESULTS: Androgens, free androgen index (FAI), LH and insulin resistance indexes were higher in the PCOS group. MOV was significantly different between the two groups: control group 4·6 ± 1·9 cm(3) , adolescent PCOS group 9·6 ± 4·4 cm(3) . The MOV threshold of 5·596 cm(3) offered the best compromise between sensitivity and specificity based on the characteristics of the operating receiver curve analysis. Therefore, an ovarian volume higher than 5·6 increased the risk of PCOS by about 15 times (OR 16·25 IC 95% 6·3-41·3). In adolescent PCOS girls, the ovarian volume was significantly associated with circulating testosterone and insulin, and indices of insulin resistance. CONCLUSIONS: During early adolescence MOV evaluation may offer an effective means to screen and follow up young girls with irregular cycles in order to prevent the long-term metabolic disturbances of the polycystic ovary syndrome.

RESUMO

OBJECTIVE: To define the prevalence and the features of polycystic ovary syndrome (PCOS) in patients with psoriasis. To our knowledge, the association between PCOS and psoriasis has not been explored in previous studies. Psoriasis is linked with metabolic syndrome, insulin resistance, and non-alcoholic fatty liver disease, which are features often associated with PCOS. DESIGN: A cross-sectional analysis was performed between January 2010 and April 2012. SETTING: Unit of human reproductive pathophysiology, Catholic University Hospital. PATIENT(S): We prospectively analyzed 51 patients with psoriasis and 102 healthy age- and body mass index (BMI)-matched controls. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): The prevalence and characteristics of PCOS women of reproductive age with chronic plaque psoriasis. RESULT(S): The prevalence of PCOS was greater in patients with psoriasis than in matched control subjects (47.05% and 11.76%, respectively; odds ratio, 6.66; 95% confidence interval 2.95-15.07). Among the women with psoriasis, the prevalence of Psoriasis Area and Severity Index ≥10 was higher in patients with PCOS than in subjects without PCOS (odds ratio, 3.5; 95% confidence interval 1.04-11.72). CONCLUSION(S): The prevalence of PCOS in women with psoriasis is remarkably greater than in age- and BMI-matched control women.

RESUMO

OBJECTIVE: To study the frequency of CD4(+)CD28(null) T cells, which are aggressive T lymphocytes associated with recurrent coronary instability and type 2 diabetes mellitus, in different polycystic ovary syndrome (PCOS) phenotypes and in age- and body mass index-matched healthy women. DESIGN: Retrospective cohort observational study. SETTING: Unit of human reproductive pathophysiology, university hospital. PATIENT(S): A total of 167 PCOS patients and 102 control subjects. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): CD4(+)CD28(null) T cell frequency, high-sensitive C-reactive protein levels, and other glucose-metabolic parameters. RESULT(S): CD4(+)CD28(null) frequency was significantly higher in all PCOS groups than in control subjects. CD4(+)CD28(null) frequency was significantly higher in nonhyperandrogenic phenotype (5.7%, range 3.2-7.1) than in phenotypes with hyperandrogenism (H) + oligoamenorrhea (O) + polycystic ovary (PCO) (3.5%, range 1-5.8), H + O (3%, range 1.8-4.7), and H + PCO (2.63%, range 1.2-4.1). The relative risk of non-H phenotype for PCOS women in the highest quartile for CD4(+)CD28(null) frequency compared with PCOS women with the lowest quartile was 3.2 (95% confidence interval 1.9-5.8). CONCLUSION(S): Cardiovascular risk evaluation should be performed in all PCOS phenotypes. In particular, we demonstrated that the non-H phenotype has potentially increased cardiovascular risk in terms of CD4(+)CD28(null) frequency.

RESUMO

OBJECTIVE: The objective of this study is to determine the ability of metformin treatment in reducing the prevalence of metabolic syndrome (MS) and its hepatic involvement in young hyperinsulinaemic overweight patients with polycystic ovarian syndrome (PCOS). DESIGN: Clinical Trial. PATIENTS: We recruited 140 hyperinsulinaemic overweight women with PCOS in their reproductive age. Metformin treatment (500 mg × 3/die) was prescribed to each patient for twelve months. MEASUREMENTS: The primary outcome was to evaluate the prevalence of nonalcoholic fatty liver disease (NAFLD) and MS in hyperinsulinaemic overweight patients with PCOS. The secondary outcome was to evaluate, in the same patients, the effects of metformin therapy on endocrine, metabolic and hepatic parameters. RESULTS: At basal evaluation, NAFLD was diagnosed in 81 of 140 patients with PCOS (57·85%); MS was present only in the NAFLD group (32·09%vs 0%; P < 0·001). After twelve months, metformin is able to significantly reduce, in the same group, the prevalence of MS (28·9%vs 13·5%; P < 0·01). An improvement of hepatic parameters and a significant decrease in oligomenorrhea (85·7%vs 19%, P < 0·001) were also observed. CONCLUSIONS: Treatment with metformin is indicated in all hyperinsulinaemic overweight patients with PCOS, especially in those with NAFLD. These data appear even more interesting considering their increased risk to develop metabolic and hepatic complications.

RESUMO

Women affected by polycystic ovary syndrome (PCOS) have an increased risk of cardiovascular disease. We demonstrated that women with PCOS showed an expansion of CD4(+)CD28(null) T cells, an aggressive population of T lymphocytes that has been recently associated with recurrent coronary instability and type 2 diabetes mellitus. This sheds new light on possible mechanisms responsible for the higher rate of cardiovascular disease among women with PCOS.

RESUMO

OBJECTIVE: To demonstrate the noninferiority of highly purified menotropin (HP-hMG) compared with recombinant FSH (rFSH) regarding clinical pregnancy rate (PR) in intrauterine insemination (IUI) cycles. DESIGN: Prospective randomized noninferiority trial. SETTING: Unit of physiopathology of human reproduction, university hospital. PATIENT(S): Five hundred twenty-three patients with unexplained infertility or mild male infertility undergoing controlled ovarian hyperstimulation for IUI. INTERVENTION(S): Patients were randomized for treatment with rFSH (262 patients) or HP-hMG (261 patients). Insemination was performed 34-36 hours after hCG injection. MAIN OUTCOME MEASURE(S): The primary outcome was clinical pregnancy rate (PR). The secondary outcome was the number of interrupted cycles for high risk of ovarian hyperstimulation syndrome (OHSS) and multiple pregnancy. RESULT(S): The clinical PR was 19.7% (95% confidence interval [CI] 15.3%-25.1%) in the HP-hMG group and 21.4% (95% CI 16.9%-26.8%) in the rFSH group [absolute difference -1.7% (95% CI -8.6%-5.2%)]; therefore, the noninferiority was demonstrated. The number of interrupted cycles for OHSS risk and multiple pregnancy was significantLy higher in the rFSH group, 8.4% (95% CI 5.6%-12.4%) than in the HP-hMG group 1.2% (95% CI 0.4%-3.3%) [absolute difference -7.27% (95% CI -11.3 to -3.7)]. CONCLUSION(S): HP-hMG is not inferior compared with rFSH regarding clinical PR.

RESUMO

OBJECTIVE: To evaluate the effects of the GnRH antagonist cetrorelix on the gonadal axis in patients with polycystic ovary syndrome (PCOS). DESIGN: Observational clinical study. SETTING: Academic research center. PATIENT(S): Ten patients with PCOS and 10 controls with normal ovulation. INTERVENTION(S): Patients received a daily cetrorelix injection (0.25 mg SC at 9:00 am) for 6 days, starting from day 3 of the menstrual cycle. MAIN OUTCOME MEASURE(S): Serum gonadotropin, E(2), T, 17-OH-P, and androstenedione plasma levels were evaluated at baseline and at 12 and 24 hours after each daily injection. These hormones were also assayed at days 10, 12, and 14 of the menstrual cycle. RESULT(S): We observed in patients with PCOS a significantly higher suppression of FSH and LH for the entire length of therapy; LH recovery secretion was significantly higher in the PCOS group. Regarding androgens, we found a greater suppression of T. Androstenedione and 17-OH-P showed a trend toward a higher suppression in PCOS. CONCLUSION(S): Gonadotropin and androgen suppression by GnRH antagonist is more effective in PCOS than in controls, suggesting a higher sensitivity of GnRH receptors in PCOS to this drug.

RESUMO

We investigated the effect of nicotine and its methylated metabolite, N-methyl-nicotine (M-nicotine), on human luteal cells by measuring release of progesterone and prostaglandins (PGs) from cultured cells and by testing gene expression of vascular endothelial growth factor (VEGF), an angiogenic factor strictly involved in luteal pathophysiology. Primary cultures of human luteal cells were treated for 24 h with nicotine and M-nicotine (from 10(-6) to 10(-11) M) either alone or combined with hCG (25 ng/ml); progesterone and PGs were assayed in the culture medium. In another group of experiments, luteal cells were treated for 24 h with nicotine and M-nicotine (10(-7) M) to perform reverse transcriptase-polymerase chain reaction on VEGF mRNA. Nicotine and M-nicotine negatively affected basal luteal steroidogenesis at all tested concentrations, but neither was able to affect hCG-induced progesterone release. Both substances were able to significantly increase PGF2alpha release from luteal cells, with a dose-related efficacy for M-nicotine. On the contrary, PGE2 release was significantly inhibited by both nicotine and its metabolite. Finally, nicotine was able to increase VEGF mRNA expression significantly, whereas M-nicotine was not. In conclusion, nicotine and M-nicotine can induce a sort of luteal insufficiency by inhibiting progesterone release, probably through modulation of the PG system.
