BACKGROUND The global obesity epidemic has paralleled a decrease in semen quality. Yet, the association between obesity and sperm parameters remains controversial. The purpose of this report was to update the evidence on the association between BMI and sperm count through a systematic review with meta-analysis. METHODS A systematic review of available(More)
BACKGROUND Changes in the endometrium are not regulated exclusively by ovarian hormones; the immune system has also been implicated in normal endometrial function, similar to processes taking place during inflammatory and reparative path. Many cytokines are crucially important for reproductive processes, and the role of cytokines in the female reproductive(More)
OBJECTIVE To evaluate advanced maternal age as a rationale for performing intracytoplasmic morphologically selected sperm injection (IMSI). STUDY DESIGN This study included couples undergoing intracytoplasmic sperm injection (ICSI) as a result of advanced maternal age (≥37 years old). Sample size calculations were based on the assumption that a 15%(More)
The objective of this study was to compare (i) the intracytoplasmic sperm injection outcomes among groups with different total motile sperm count ranges, (ii) the intracytoplasmic sperm injection outcomes between groups with normal and abnormal total motile sperm count, and (iii) the predictive values of WHO 2010 cut-off values and pre-wash total motile(More)
The present case-control study aimed to identify the effect of sperm cryopreservation on the quality of the embryo and on the probability of blastocyst formation when oocytes free of dimorphisms are injected and when at least one dymorphism is present. The study included 22 186 zygotes, obtained from 2802 patients undergoing intracytoplasmic sperm injection(More)
This study evaluated the influence of sperm origin and basic sperm parameters on blastocyst implantation competence. The study included 2912 embryos obtained from 370 patients undergoing intracytoplasmic sperm injection cycles, with embryo transfer on day 5 of development. The embryos were divided into experimental groups according to their origin: (i)(More)
A polysyloxane vaginal ring containing 1g of natural progesterone was developed as luteal supplementation for women treated with IVF-embryo transfer and for agonadal women participating in an oocyte donation programme. The ring provides continuous release of progesterone (10-20 nmol/l) for 90 days. The efficacy of this form of progesterone supplementation(More)
