Using this vitrification technique for freezing, we can preserve eggs as well as embryos and sperm. This allows us to preserve the fertility of young women for the future in egg banks if they wish to delay childbearing. In St. Louis, we have demonstrated for the first time that an entire...
trophoblast- the membrane that forms the wall of the blastocyst in early development; aids implantation in the uterine wall; "after implantation of the blastocyst in the uterine wall the trophoblast divides into two layers, the chorion and the placenta" ...
In males, gentle abdominal pressure was applied, in order to check for the presence of sperm. After that, all the fish were weighed. In 2015, after the sex ratio sampling, 4 large females (mean weight ± S.D. of 2.20 ± 0.52 kg) were removed and 4 younger males (3 years old, ...
How long does sperm production continue in males? In the process of meiosis, how many viable eggs are produced by the female each time meiotic cell division occurs? Describe the similarities and differences between sperm and egg. Discuss male reproduction. Where does meiosis occur? How is s...

However, sperm production, morphology and motility were unaffected by treatment. In a more recent study (Murphy et al., 2017), boars fed 75 g MA (All-G-Rich, Alltech) per day on top of a basal diet increased semen volume and sperm numbers per ejaculate compared to pigs fed control ...
