p. 343. The mysteries of reproductionlocked

  • Martin Luck

Abstract

‘The mysteries of reproduction’ begins with Pergonal (human menopausal gonadotrophin), a hormone preparation extracted from urine which contains pituitary hormones crucial to the reproductive cycle. Prolactin, another anterior pituitary hormone, affects fertility in women, but is also found in many different kinds of animal and has more than 300 different actions. Prolactin has the general effect of controlling the movement of salts and water across membranes, especially in tissues related to the skin. The important roles of hormones—progesterone, chorionic gonadotrophin, prostaglandin, oxytocin, oestrogen, and testosterone—in the reproductive cycle, human and gender development, the menopause, and the ageing process are also described.
