A vasectomy is a fairly minor surgical procedure that involves severing of the sperm duct in order to cause male sterility. In the event that the patient wants to regain fertility, this procedure can be reversed. The vasectomy reversal can be done...
The most common method of sperm collection for semen analysis or insemination is self-collection by masturbation and ejaculation into a sterile collection cup. Typically, the patient is given a clean private area that is stocked with erotic...
The reproductive organs of humans, while ostensibly quite different from males to females, actually share most of their developmental roots. Early fetuses have identical reproductive systems, despite the fact that a baby's gender is determined...
Bacterial infections in men are a common cause of infertility. Scarring at the site of Infection can cause infertility if scarring blocks the tubes within the testis, epididymis or ejaculatory ducts. The immune response itself can cause the...
Although the reproductive systems of men and women are anatomically different, they develop from similar embryological origins, have a similar general function of passing on genetic material from one generation to the next, and are under the...
The male and female gonads--the testes and ovaries, respectively--arise out of a common embryonic tissue called the primordial gonad. Likewise, the male penis and female clitoris arise from a common precursor called the genital tubercle. For the...
Sperm are created in the testes, also called testicles, the male sex glands found in the scrotum, the sac-like bags of skin on either side of the penis. Testicles hang outside the body because sperm need to be kept 1.5 to 2.5 degrees Celsius...
The male and female reproductive organs have evolved over millions of years to propagate the species. Both male and female organs arose from common embryonic origins. In the presence of active male-determining genes on the Y-chromosome, the...
