Our purpose was to utilize current reproductive technologies to treat an infertile female lowland gorilla.Following pituitary down-regulation with a gonadotropin releasing hormone agonist and follicular stimulation with human menopausal gonadotropins

The hemizona assay is a diagnostic test used to evaluate the binding potential of spermatozoa to zonae pellucida and has been used to predict fertilization potential in the human. In this study, frozen-thawed gorilla spermatozoa were coincubated with

To determine whether ejaculates consist of various populations of sperm with varying degrees of fertilizing capacity, semen was filtered through a glass-wool column and the filtrate aliquoted sequentially into three portions. The ejaculate and its re

To investigate the effect of preincubation of human sperm in milk on their ability to penetrate zona-free hamster oocytes, 27 ejaculates were studied. Each ejaculate was divided into two portions and incubated in either milk or TEST yolk (TESTY) for

Enhanced penetration of zona-free hamster oocytes occurs after spermatozoa have either been treated with TEST--yolk buffer or processed by glass wool filtration. The present study was conducted to determine if a synergistic effect on fertilizing abil

Our purpose was to test whether treatment of zona pellucida with egg yolk enhances its receptiveness to sperm binding. Hams F-10 supplemented with 0.06 g% freeze-dried egg yolk (TM) was evaluated using the hemizona assay. Ham's F-10 supplemented with

To evaluate, using the hemizona assay (HZA), whether egg yolk treatment of human sperm enhances binding to the human zona pellucida in vitro and to determine whether such a treatment is as efficient as the standard swim-up procedure for promoting spe

In at least 4 of 7 cases, fertilization of intact human oocytes was more successful when spermatozoa were pretreated with TEST yolk medium at 5 degrees C for 2 hours as compared with the standard treatment with Ham's F-10 only. Both pregnancies that
