The aim of this study was to evaluate whether women's ages at conception and the ratio of male to female infants are associated with various ovulation patterns.An observational clinical study was conducted in private OB/GYN clinics. Infertile women w

The purpose of this study was to determine which morphokinetic variables are related to embryo gender in a cohort of consecutive live births obtained through single blastocyst transfer following mild ovarian stimulation. Eighty-one live births (49 %

Objective To ascertain the rate of blastocyst collapse observed by time-lapse monitoring in a retrospective cohort of unselected infertile patients undergoing single blastocyst transfer and to determine its association with live birth. Design Blastoc

Publikováno v: Fertility and sterility. 101(4)

Objective To determine the efficiency of oocyte retrieval (OR) timing based on the occurrence of spontaneous LH surge during natural cycle IVF (ncIVF) treatment. Design Retrospective cohort study. The cohort was divided into five subgroups according

Publikováno v: Fertility and Sterility. 104:1175-1181.e2

Objective To determine how standard IVF vs. intracytoplasmic sperm injection (ICSI) fertilization influences early and late morphokinetic parameters during prolonged embryo culture. Design Five-hundred expanded blastocysts that were monitored in a ti
