Advances in Assisted Reproductive Technologies pp Cite as. Microscopic examination of liquefied semen samples is the simplest, and must be the most common, investigation of infertility. The coagulation and liquefaction of human semen is that reproductive phenomenon most accessible to the reproductive biologist Nevertheless we still lack a convincingly physiological explanation. Comparative studies 1 have regarded it as a not-very-effective semen retention mechanism, comparing it with the vaginal plug of some rodents. Suggestions 5,6 that these first sperms escape the inhospitable vaginal milieu, into a cervical reservoir, have been rendered less plausible by the discovery 7 that the spermatozoa do not experience vaginal acidity, because of the immediate buffering effect of the semen.

Semen collection refers to the process of obtaining semen from human males or other animals with the use of various methods, for the purposes of artificial insemination , or medical study usually in fertility clinics. Semen can be collected via masturbation [1] e. The best specimen is produced when a short period of 3—5 days of abstinence is observed. More prolonged period does not yield better results. For semen collection from stallions, the most common method used is an artificial vagina; after collecting semen, it is tested, diluted, then stored according to the intended use. Semen can be either liquid or frozen.

A nice shot of semen allows a man to pass on a genetic code through the ages, offering the closest thing to eternal life humans are ever likely to achieve. But such wonders aren't straightforward.

Squirrels, like many other mammals, engage in a process of courtship and mating that involves female mate choice. Squirrels are polygynandrous, meaning that both males and females may mate with several partners. Once mated, the female takes on sole responsibility for parental care of the offspring. In some species, the female will rear two litters per year.
