Capacitation is a physiological process that sperm must undergo to gain the ability to penetrate and fertilize an egg. It involves biochemical changes in the sperm membrane and an increase in motility, occurring after ejaculation in the female reproductive tract or artificially in vitro.

Capacitation

Physiological process

Sperm are the male reproductive cells responsible for fertilizing the female egg, initiating the process of conception. They are produced in the testes and carry half of the genetic material required to form a new individual.

Biochemical changes refer to the alterations in the chemical processes and substances within living organisms, often in response to environmental stimuli, disease, or developmental processes. These changes can affect metabolic pathways, enzyme activities, and cellular communication, ultimately influencing an organism's physiology and behavior.

Increase in motility

Ejaculation is a physiological process involving the expulsion of semen from the male reproductive system, typically occurring as a result of sexual stimulation. It is a complex reflex action that involves coordination between the nervous system and various muscles, playing a crucial role in reproduction and sexual health.

Ejaculation

The female reproductive tract is a complex system responsible for the production of gametes, fertilization, and the nurturing of a developing fetus. It includes structures such as the ovaries, fallopian tubes, uterus, and vagina, each playing a crucial role in reproductive health and function.
