The number of eggs released at ovulation may be greater than the number of offspring born, if some of these ovulated eggs and/or embryos disappear during gestation. Although this process can potentially exert significant effects on reproductive output, logistical problems have discouraged studies on ...
says Michael Eisenbach at the Weizmann Institute of Science in Rehovot, Israel. Future studies should test whether these results also occur in chemicals produced by mature eggs released after ovulation, since follicular fluid contains chemicals that are produced before an egg has fully matured...
A double-yolked egg occurs when two egg yolks are released into a hen's oviduct too close together and end up encased within the same shell. ... Sometimes your double yolkers will have half-size yolks, so two would count as one. But if they are full-size,you'd count them as two ...
Professor Nakagata and his colleagues came up with the idea of adding inhibin antiserum to the superovulation process. The hormone inhibin is released from the gonads during development and is a secretion regulator of FSH. FSH is secreted from the pituitary gland and limits the number of eggs p...

Approximately every 25 hours, one yolk is mature enough to be released into the funnel of the oviduct, a process called ovulation, which usually occurs within an hour after the previous egg was laid. During a yolk’s journey through the two-foot long oviduct, it is fertilized (if sperm ar...
In salmonids, eggs are released into the body cavity at the time of ovulation and are bathed in a liquid called “coelomic” or “ovarian” fluid. The eggs can be held in the abdomen in this fluid for at least a week without loss of fertility (Springate et al., 1984). Several studie...

It is supposed that the process of egg fusion may be caused either by a similar mechanism to sperm-egg fusion, or by products released during the sperm acrosome reaction.doi:10.1002/mrd.1120060302Antonin PavlokPavel TrávníkVáclav Kopeny
