Excess of sperm

Chris - This is a very good question; healthy testes make sperm at the rate of between and sperm cells per second. These collect in a long coil of tubes above and behind each testicle called the epididymis, where they are stored until needed. The testes hang external to the body within the scrotum to achieve an optimal temperature for sperm production. This is because sperm are made most efficiently at a slightly lower temperature than body temperature. In the epididymis the sperm are nourished and make their way to the vas deferens, which is a muscular tube connecting the testis to the urethra up inside the male body.

What happens to sperm that isn't ejaculated? | Questions | Naked Scientists

In medicine , hyperspermia is a condition in which a male has an abnormally large ejaculate or semen volume , [1] and is generally defined in humans when the ejaculate is above 5. It is the opposite of hypospermia. From Wikipedia, the free encyclopedia. Shaw's Textbook of Gynaecology, 15e.

What You Should Know About Hyperspermia

Redundancy—the excess of supply over necessity—has recently been proposed for human sperm cells. However, the apparent superfluity of cell numbers may be necessary in order to circumvent the hazards, many of which can be quantified, that can occur during the transition from gametogenesis within the testes to zygosis within the female reproductive tract. Sperm cell numbers are directly related to testicular volume, and it is owing to a redundancy, and the possible exaptation, of this latter parameter that a putative excess of sperm cells is perceived. Related to this parameter, however, is concern over the recent world-wide decline of sperm cell numbers and semen quality, a trend which also takes into account possible increases and decreases in these parameters due to circannual and seasonal variations, 8,9 particularly in temperate zones. The initial problem—that of the apparent redundancy of sperm numbers—reduces to the observation that the fertilization of one single egg liberated by the ovary of a female appears to require the deposition of an ejaculate from the male of many tens of millions of sperm cells.
