Human Reproductive Hormones
Posterior Pituitary
LH
Surge causes ovulation
Growth of corpus luteum
Stimulates theca cells to release androgenic hormones
Growth and development of ovaries
Posterior Pituitary
FSH
Growth of spermatogonia
Maturation of primary follicles into secondary follicles
Maturation of graafian follicle
Promotes maturation of primary oocytes
Growth and development of ovaries
Internal Theca of Graafian Follicle/Placenta
Oestrogen
Regulates menstrual cycle
Development of the primary follicle into graafian follicle
Corpus Luteum/Placenta
Progesterone
Maintains pregnancy
Prepares uterus for pregnancy
Secondary sexual characters
Anterior Pituitary
ICSH
Promotes growth of interstitial cells
Interstitial Cells
Testosterone
Crucial for spermatogenesis
Promotes secondary sexual characteristics in males
Anterior Pituitary
Prolactin
Synthesis of milk from alveolar epithelium
Posterior Pituitary
Oxytocin
Increases sperm motility
Contraction of smooth muscles of myometrium during the first stage of parturition
Causes uterus to contract during parturition and initiates labour pain
Stimulates the release of milk from the mother's breast
Placenta
hCG
Promotes the growth of corpus luteum during pregnancy and prevents its degeneration
Corpus Luteum/Placenta
Relaxin
Relaxes the pubic symphysis during expulsion of foetus, thus widening the opening of the cervix
