Seventy-two couples, including 15 with antispermatozoal antibodies in the male partner's semen, were studied in a program of in vitro fertilization and embryo transfer. Cases were further subclassified as normospermic or oligospermic and antispermatozoal antibodies were assessed with categorization into the respective human immunoglobulin classes as(More)
Two groups of women were studied in whom a proportion of follicles had either ovulated spontaneously (7 women) or ruptured during manipulation at laparoscopy (30 women), and oocytes were recovered from the pouch of Douglas. There were no significant differences in the fertilization rates of oocytes collected in the pouch of Douglas from ovulated follicles,(More)
Our purpose was to evaluate the efficacy of direct insemination (IVF), micromanipulation by partial zona dissection (PZD), and subzonal sperm insemination (SUZI) using spermtreated with pentoxifylline (PF) ± 2-deoxyadenosine (2DA). The overall fertilization rate achieved was similar for all three fertilization techniques (33.1, 30.2, and 26.9% for IVF,(More)
Gamete intrafallopian transfer (GIFT) was performed on a series of 42 couples in whom four oocytes were replaced into the fallopian tubes and the remaining oocytes were inseminated with 100,000 motile spermatozoa. Fertilization in vitro was assessed 16 to 20 hours later. An overall pregnancy rate after GIFT of 40.0% (12/30) in normospermic couples and 16.7%(More)
