Impact of endometrial preparation on early pregnancy loss and live birth rate after frozen embryo transfer: a large multicenter cohort study (14 421 frozen cycles).

Study Question: Does the endometrial preparation protocol (artificial cycle (AC) vs natural cycle (NC) vs stimulated cycle (SC)) impact the risk of early pregnancy loss and live birth rate after frozen/thawed embryo transfer (FET)?

Summary Answer: In FET, ACs were significantly associated with a higher pregnancy loss rate and a lower live birth rate compared with SC or NC.

What Is Known Already: To date, there is no consensus on the optimal endometrial preparation in terms of outcomes. Although some studies have reported a higher pregnancy loss rate using AC compared with NC or SC, no significant difference was found concerning the pregnancy rate or live birth rate.

Results of scaphocapitate arthrodesis with lunate excision in advanced Kienböck disease at 10.7-year mean follow-up.

Unlabelled: Scaphocapitate arthrodesis with lunate excision was performed for treatment of advanced Kienböck disease in 17 patients (18 wrists). Ten were women and seven men. Five were Lichtmann Stage IIIA, 12 Stage IIIB, and one Stage IV.

Transvaginal ultrasound-guided embryo transfer in IVF.

Objectives: To determine whether transvaginal ultrasound-guided embryo transfer is a technique that can be used routinely, whether it improves IVF outcomes and whether it makes difficult transfers easier and more successful.

Material And Method: Non-randomized retrospective study conducted between 2012 and 2016 in the fertility center of the Diaconesses-Croix St-Simon hospital group. The outcomes of 3910 transfers, performed by 5 senior operators, under transabdominal ultrasound guidance are compared with those of 800 transfers, performed by 1 senior operator under transvaginal ultrasound guidance.

Anatomical causes of difficult embryo transfer during in vitro fertilization.

Objectives: Identify, define and validate through statistical analysis the anatomical causes of difficult embryo transfers (ET).

Materials And Methods: This observational study, carried out in 306 IVF candidates, compared the frequency of anatomical anomalies of the uterus and cervix in women who underwent an easy ET with that in women who underwent a difficult ET. Anatomical anomalies were detected during an assessment of the cervix and uterus including transvaginal ultrasound, hysteroscopy and a mock transfer.

[Assisted Reproductive Technologies in HIV patients: a comprehensive review of indications, techniques and results].

Assisted Reproductive Technologies (ART) are authorized in France in couples infected by the human immunodeficiency virus (HIV) since the French legislation of May 10th, 2001. The goals are to reduce the risk of viral transmission between partners and to treat an underlying infertility. The classical techniques are used: IUI, IVF or ICSI, but all of them must be done in specifically authorized laboratories.
