Sperm sorting is a means of choosing what type of sperm cell is to fertilize an egg cell using several conventional techniques of centrifugation or swim-up.Newly applied methods such as flow cytometry expand the possibilities of sperm sorting and new techniques of sperm sorting are being developed.
The volume of the semen sample (must be more than 1.5 ml), approximate number of total sperm cells, sperm motility/forward progression, and % of sperm with normal morphology are measured. It is possible to have hyperspermia (high volume more than 6 ml) or Hypospermia (low volume less than 0.5 ml). This is the most common type of fertility testing.
The spermatids are transformed into spermatozoa (sperm) by the process of spermiogenesis. These develop into mature spermatozoa, also known as sperm cells. [2] Thus, the primary spermatocyte gives rise to two cells, the secondary spermatocytes, and the two secondary spermatocytes by their subdivision produce four spermatozoa and four haploid ...

Men, too, often avoid doctors' visits, missing opportunities to proactively identify issues. Treatments for male infertility include semen analysis, lifestyle changes, and sperm-freezing.
Sperm concentrations in the volunteers decreased so much so that they were considered infertile. She was the first scientist to popularize this alternative method of contraception for men. Thermal dependence of spermatogenesis was studied in 1941 with external heat such as hot baths or saunas with temperatures above 40 °C over short periods of ...

In vitro spermatogenesis is the process of creating male gametes (spermatozoa) outside of the body in a culture system.The process could be useful for fertility preservation, infertility treatment and may further develop the understanding of spermatogenesis at the cellular and molecular level.
