The effect of cycle length on the outcome of in vitro fertilization
In order to study the effect of cycle length on the pregnancy rate in an in vitro fertilization and embryo transfer (IVF-ET) program, 173 consecutive patients were divided into short menstrual cycle (mode 26days or less) and normal cycle (mode 27days or more) groups. Patients were randomly allocated...

Zusammenfassung: | In order to study the effect of cycle length on the pregnancy rate in an in vitro fertilization and embryo transfer (IVF-ET) program, 173 consecutive patients were divided into short menstrual cycle (mode 26days or less) and normal cycle (mode 27days or more) groups. Patients were randomly allocated to one of two treatments, commencing ovarian stimulation with human menopausal gonadotropin (hMG) on either day 2 or day 4 of their cycle. The number of oocytes retrieved and embryos transferred did not differ significantly. The amount of hMG used and day of human chorionic gonadotrophin administration both differed significantly (P |
