RESUMO
Hormonal contraceptives remain among the most popular methods used by women. The purpose of this work is to review the effectiveness and use of these different methods. In addition, some side-effects are feared and/or frequently reported by users of hormonal contraceptives: unscheduled bleeding, acne, catamenial migraines, weight gain, libido and/or mood disorders. In this review of the literature, the accountability of hormonal contraceptives for the occurrence of some of these side-effects was discussed and a management strategy was proposed.

OBJECTIVE: Insulin resistance is known to worsen polycystic ovarian syndrome (PCOS). The management of insulin resistance is crucial in the treatment of PCOS and insulin-sensitizing molecule as myo-inositol (MYO) seems to have promising effects. The aim of our pilot study was to study whether supplementation with MYO can improve patients' sensitivity to clomiphene citrate (CC) in terms of ovulation and pregnancy rates. PATIENTS AND METHODS: This study included 26 patients with PCOS, eligible to ovulation induction with CC. All of them received MYO in combination with CC and folic acid, following the usual protocol. Results concerning ovulation and pregnancy rates were compared to those from our historical cohort of PCOS patients treated with CC alone. RESULTS: Ovulation rate was significantly higher with MYO+CC than with CC alone (65.5% vs. 42%, p=0.0001). The number of patients sensitive to 50 mg/d was 54% with MYO vs. 40% in our reference cohort (NS). The total resistance rate was 19% vs. 27% in the reference cohort (NS). Cumulative pregnancy rate with MYO+CC was 53.8% vs. 42.2% with CC alone (NS). Pregnancy rates per initiated cycle were 16.1% with MYO vs. 12.6% in the historical cohort (NS). DISCUSSION: Although the differences were not significant for most outcomes, probably due to the small number of patients, our pilot study seemed to show a benefit of supplementation with MYO during ovulation induction with CC in PCOS patients. CONCLUSIONS: This study proves the great interest of a RCT and re-opens the possibilities of insulin-sensitizing agents in the treatment of anovulatory patients with PCOS, such as natural products like MYO.

Patients with very low sperm count through direct sperm examination can exhibit extreme oligozoospermia or cryptozoospermia (after centrifugation). The management of these patients is a real challenge for both clinicians and biologists. In this retrospective and comparative cohort study, we compared the andrological phenotype of patients with extreme alterations of spermatogenesis and assessed whether the origin of spermatozoa (testicular or ejaculate) had any influence on intracytoplasmic sperm injection (ICSI) outcomes. A total of 161 ICSI cycles were performed using ejaculated spermatozoa from 75 patients with extreme oligozoospermia (EOS) or cryptozoospermia (CS) and 150 ICSI cycles using extracted testicular spermatozoa from 74 patients with non-obstructive azoospermia (NOA). Physical, hormonal, ultrasound assessments, and ICSI outcomes were performed in each group. Cryptorchidism was significantly more frequent in the NOA group (60.8% vs. 22.6%, p = 0.001). FSH levels were significantly higher [18.9 IU/L (5.9-27.0) vs. 15.3 IU/L (9.0-46.5), p = 0.001] and the majority of inhibin B levels measured were found mostly undetectable in the NOA group as compared to EOS/CS group (31.1% vs. 10.7%, p = 0.0004). Moreover, we found no significant differences in the respect to the fertilization rates (48.9% and 43.3%, p = 0.43), implantation rates (17.4% and 15.9%, p = 0.77), and percentage of top quality embryo (22.4% and 20.4%, p = 0.73) between the two groups. The clinical pregnancy rates per embryo transferred were comparable in both groups (28.3% and 27.4%, p = 0.89). In this study, we showed for the first time a different andrological phenotype between EOS/CS and NOA groups. Indeed, cryptorchidism was significantly more frequent with more severe endocrine parameters found in the NOA group. These results reflect a more profound alteration in spermatogenesis in NOA patients. However, there was no difference in ICSI outcomes between NOA and EOS/CS groups.

Many studies exist on the impact of female age on fertility, success of assisted reproductive technologies and on obstetric, fetal and neonatal adverse outcomes. Late paternity seems commonplace especially in the media But there are reliable scientific data which confirm decline of fertility related to male age but also an increased risk of genetic diseases for the offspring. The objective of this article is to make a synthesis of the literature on this subject.

The prognosis of metastatic malignant mesenchymal tumors (MMT) remains poor. Given the chemosensitivity of these neoplasms, a phase II study of high-dose thiotepa (HDT) was performed to evaluate the efficacy of this drug in this particular subset of pediatric tumors. Between 1986 and 1998, 18 patients, previously treated with conventional therapy for metastatic or refractory MMT, entered the study. Thiotepa was administered at a daily dose of 300 mg/m2 for 3 consecutive days. Hematopoietic stem cell rescue, consisting of bone marrow transplantation or peripheral stem cell transplantation, was performed 2 days after completion of HDT. A response exceeding 50% was observed in 6/18 patients (response rate 33%). Toxicity was severe but never led to death. HDT used at a dose of 900 mg/m2 yields measurable anti-tumor activity in previously treated patients. The next step in these particularly poor prognosis metastatic MMT will be to investigate HDT combined with other drugs, known to be efficient at high doses.
