Our findings were generally reassuring in not confirming a link between ovulation-inducing drugs and ovarian cancer; risk was increased, however, among women who, despite having used clomiphene citrate, remained nulligravid.
A home pregnancy test with weeks since ovulation results had 93% agreement with time since ovulation and 99% with ultrasound, which provides an estimate more accurate than last menstrual period and earlier than ultrasound.
We define the times associated with morphological changes that occur in embryo development based on time lapse. Subgroups of embryos were compared and related with blastocyst formation and implantation.
In this cross-sectional study of healthy young men, dietary intakes of the carotenoids b-carotene and lutein were associated with higher sperm motility, while lycopene intake was associated with better morphology.
We demonstrate the ability of prefreeze semen quality to predict cryosurvival in terms of sensitivity and precision. This information allows appropriate counseling about the future possibilities of fertility for the patient.
Testicular fibroblast growth factor 9 (FGF9) is expressed in adult Leydig cells, and its expression is significantly decreased in patients with Sertoli cell–only syndrome. A promoter polymorphism of FGF9 contributes to its aberrant expression.
Intracytoplasmic sperm injection (ICSI) with sperm from a man with Eagle-Barrett syndrome (EBS) resulted in the births of two normal healthy male infants, suggesting that EBS is not transmitted to male offspring.
