The main objective of this study is to compare clinical pregnancy rates between two groups of women who have progesterone levels below 10 ng/mL on the day of frozen embryo transfer: group 1 (vaginal micronized progesterone supplemented with progesterone intramuscular 50 mg per day) and group 2 (vaginal micronized progesterone with no supplementation)
Prospective, open, randomized, parallel, two-arm trial to compare the clinical pregnancy rate between most commonly used two embryo transfer techniques: trial followed by transfer technique and afterloading technique
In assisted reproductive technology, adenomyosis patients are characterized by lower clinical pregnancy rate, lower implantation rate and higher abortion rate. The purpose of this study is to explore whether low molecular weight heparin can reduce the abortion rate of adenomyosis patients in frozen thawed embryo transfer cycles.
For this project, 4 groups of 38 infants have been created so as to evaluate the impact of Assisted-Reproduction Technology (ART) and more particularly the two procedures classically used in ART: the freezing/thawing of embryos and prolonged embryo culture (five days of culture in appropriate in vitro conditions to allow development of the embryo) in contrast with shorter culture of only two days. Participation consists in accepting samples to be taken at the birth of the infant: from the umbilical cord. from the placenta.
