Secretion of androgens by testes is regulated by:

  • LTH

  • FSH

  • ICSH

  • Oxytocin

Solution

C.

ICSH

Testosterone, and dihydrotestosterone are secreted by testes collectively known as androgens. Secretion of androgens by testes is regulated by interstitial cell stimulating hormone (ICSH). It is a luteinizing hormone (LH).

LTH stands for luteotropic hormone. It is a substance, usually a peptide or steroid, produced by one tissue and conveyed by the bloodstream to another to effect physiological activity. It is produced by the pituitary gland of mammals.

Follicle-stimulating hormone or FSH is a gonadotropin, a glycoprotein polypeptide hormone. It is synthesized and secreted by the gonadotropic cells of the anterior pituitary gland, and regulates the development, growth, pubertal maturation, and reproductive processes of the body.

Oxytocin or Oxt is a peptide hormone and neuropeptide. It is produced by the para- ventricular nucleus of the hypothalamus and released by the posterior pituitary. It plays a role in social bonding, sexual reproduction, childbirth, and the period after childbirth.
