One hundred thirteen embryo transfers (ETs) were performed in an in vitro fertilization and ET program of which residual or extruded embryos were found in 17 transfers (15%). Residual or extruded embryos are those embryos found outside the uterine cavity, either at the cervical os, on the vaginal speculum, or remaining in the catheter after an ET. Patients(More)
A study compared the in vitro fertilization results in women with one or two ovaries. Eighteen percent (23/125) of in vitro fertilization/embryo transfer cycles were in patients with one ovary. One-ovary patients averaged 4.2 follicles (greater than or equal to 10 mm) as compared to 7.9 in two-ovary patients, and significantly fewer ova were recovered from(More)
Our laboratory has recently detected the presence of platelet-activating factor (PAF)-like activity in human spermatozoa. To gain further insight into the role of PAF on the male reproductive system, this study, using videomicroscopy, evaluated the effects of synthetic PAF on the motility of human spermatozoa. Treatment of 20 human semen samples with 3.69 x(More)
Platelet activating factor is rapidly gaining acceptance as a potent mediator in many reproductive processes. This study presents data that indicate a direct role of platelet activating factor in fertilization. Platelet activating factor was shown to significantly increase (p less than 0.001) the fertilization rate of mouse oocytes in vitro. Furthermore,(More)
Implants or tiny circumscribed nodules of endometrial tissue were found in all female mice given intraperitoneal injections of fragments of human normal (proliferative and secretory) or ectopic (endometrioma) endometrium. Half of these animals received estrogen supplementation and the other half received none. The endometriosis tissue present in these(More)
Our concept of the pathogenesis of acute salpingitis and advanced pelvic infection, such as tuboovarian abscess, is evolving. Although Neisseria gonorrhoeae and Chlamydia trachomatis are thought to play a significant role in acute pelvic inflammatory disease, other microorganisms, such as aerobes and anaerobes, have repeatedly been reported to play a(More)
