Somatostatin, also known as growth hormone-inhibiting hormone (GHIH) or by several other names, is a peptide hormone that regulates the endocrine system and affects neurotransmission and cell proliferation via interaction with G protein-coupled somatostatin receptors and inhibition of the release of numerous secondary hormones.

In males, FSH stimulates sperm maturation, which is inhibited by the hormone inhibin. The placenta produces two steroid hormones – oestrogen and progesterone. Progesterone acts to maintain pregnancy by supporting the lining of the uterus (womb), which provides the environment for the fetus and the placenta to grow. Progesterone prevents the shedding of this lining , since this would result in pregnancy loss.
