Contraception during medical studies: A French study of 2,323 residents.

OBJECTIVE: The main objective of this work was to establish the contraceptive profile of French female medical residents and to assess the impact of workload on their choice of contraception method as well as difficulties encountered. STUDY DESIGN: We conducted a descriptive, cross-sectional, prospective national study over six months, between May and October 2019, using an anonymous online survey sent to all female medical residents in France. We formed two study groups according to reported working hours: W+ and W-. Grouping was based on three criteria: weekly workload, weekly night duty, and weekend duty per month. RESULTS: Of the 17,120 active female residents, the response rate was 15.42%. Oral contraception was the most commonly used method. The contraceptive profile of female residents was similar to that of the general French population. The W+ group of residents experienced more frequent contraceptive difficulties that had no impact on their choice of contraception. Despite the difficulties of using contraception, the W+ group used effective corrective methods, allowing them to prevent unplanned pregnancies. Residents in the W+ group reported more irregular gynecological follow-up. CONCLUSION: Better gynecological monitoring during medical studies would optimize contraceptive choices made by female medical residents in France.

Follicular GH and IGF1 Levels Are Associated With Oocyte Cohort Quality: A Pilot Study.

Introduction: Oocyte quality contributes to the development of an optimal embryo and thus a successful pregnancy. The objective of this study was to analyse the association between oocyte cohort quality and the follicular levels of growth hormone (GH), insulin-like growth factor 1 (IGF1), 25-hydroxy vitamin D (25OHD), thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4) and antithyroid antibodies, as a function of intracytoplasmic sperm injection (ICSI) outcomes. Material and methods: We conducted a prospective comparative pilot study from January 2013 to December 2017. 59 ICSI cycles constituted an abnormal oocyte cohort (n=34 cycles, in which more than 50% of oocytes presented at least one morphological abnormality) and a normal oocyte cohort (n=25 cycles, in which 50% or less of the oocytes presented at least one morphological abnormality). GH, IGF1, 25OHD, TSH, fT3, fT4 and antithyroid antibodies were measured in follicular fluid. Results: The fertilisation rate was lower in the abnormal oocyte cohort (65.5% vs. 80%, respectively, p=0.012). Oocytes' proportion with at least one abnormality was 79.4% in the abnormal oocyte cohort and 29.0% in the normal oocyte cohort. The mean number of morphological abnormalities per oocyte was significantly higher in the abnormal oocyte cohort. The follicular levels of GH (4.98 vs. 2.75 mIU/L, respectively; p <0.01) and IGF1 (72.1 vs. 54.2 ng/mL, respectively; p=0.05) were higher in the normal oocyte cohort. There was no association with follicular levels of TSH, fT3, fT4, antithyroid antibodies, or 25OHD. Conclusion: Oocyte cohort quality appears to be associated with follicular levels of GH and IGF1.
