HCG: Is it the Best Choice for Ovulation Triggering?
With the increasing use of gonadotropin releasing hormone antagonist protocols, it has become an option to trigger ovulation with gonadotropin releasing hormone agonist which has several advantages over human chorionic gonadotropin triggering; among those an elimination or reduction in ovarian hyperstimulation syndrome, and a reduction in luteal phase discomfort.

متن کاملThe Repeatability of Ovulation Rate in Merino Ewes
The ovaries of 3 groups of Merino ewes were examined for corpora lutea by laparoscopy every 17 days between 28.3.74 and 16.6.75. During the 1974 breeding season the mean body weight of the ewes was maintained at 37 kg. Between the 1974 and -1975 breeding seasons the nutrition of the ewes was varied to give groups of ewes with mean body weights of 37, 41 and 46 kg; groups of ewes of low, medium ...

15 صفحه اولOxytocin-induced cervical dilation and cervical manipulation in sheep: effects on laparoscopic artificial insemination.
The difficulty of cervical penetration severely limits the use of transcervical AI (TAI) in sheep, and trauma from cervical manipulation (CM) may reduce fertility after TAI. We investigated the effects of cervical dilation using exogenous oxytocin (OT) to facilitate TAI and its effects on reproductive variables after laparoscopic AI (LAI). Estrus was synchronized by inserting pessaries impregna...
