Pregnancy rates in donors versus recipients according to the serum progesterone level at the time of human chorionic gonadotropin in a shared oocyte program.
Previous data suggested a subtle increase in serum P at the time of hCG injection without LH surge reduces the PR of women having oocyte retrievals for IVF; this study compared PRs of recipients in aExpand

Embryo transfer technique as a cause of ectopic pregnancy in in vitro fertilization.
A randomized prospective study was performed to compare the effects of a midfundal versus a deep fundal transfer technique on subsequent intrauterine and ectopic PRs after IVF. The clinicalExpand

The effect on IVF outcome of small intramural fibroids not compressing the uterine cavity as determined by a prospective matched control study.
BACKGROUND Several studies have reported that the presence of intramural fibroids affects conception following IVF. We attempted to corroborate or refute the conclusions relating to IVF andExpand

A guanine nucleotide‐binding regulatory protein in human sperm mediates acrosomal exocytosis induced by the human zona pellucida
Guanine nucleotide‐binding regulatory proteins play key intermediary roles in regulating zona pellucida‐mediated acrosomal exocytosis in mouse and bull sperm. Since human sperm possess a Gi‐likeExpand

Increased endometrial thickness on the day of human chorionic gonadotropin injection does not adversely affect pregnancy or implantation rates following in vitro fertilization-embryo transfer.
OBJECTIVES To investigate the controversy whether an increased endometrial thickness has an effect on pregnancy, implantation, or abortion rates in in vitro fertilization-embryo transfer (IVF-ET)Expand

Two methods of achieving pregnancies despite subnormal hypo-osmotic swelling test scores.
OBJECTIVE To determine whether either the use of intracytoplasmic sperm injection (ICSI) or chymotrypsin-galactose pretreatment of sperm before IUI can improve pregnancy results in female partners ofExpand
