Testis, plural testes, also called testicle, in animals, the organ that produces sperm, the male reproductive cell, and androgens, the male hormonesin humans the testes occur as a pair of oval-shaped organs they are contained within the scrotal sac, which is located directly behind the penis and in front of the anus. Androgen insensitivity syndrome (ais) is an intersex condition that results in the partial or complete inability of the cell to respond to androgens the unresponsiveness of the cell to the presence of androgenic hormones can impair or prevent the masculinization of male genitalia in the developing fetus, as well as the development of male secondary sexual characteristics at puberty, but does.
