Hormones in Human Reproduction Flashcards

All 6 cards in this deck

What is the main female reproductive hormone, and where is it produced?: Oestrogen, produced in the ovary.
What is the main male reproductive hormone, where is it produced, and what does it do?: Testosterone, produced by the testes; it stimulates sperm production and the male secondary sex characteristics at puberty.
What is the role of FSH (follicle stimulating hormone) in the menstrual cycle, and where is it produced?: It causes maturation of an egg in the ovary; it is produced by the pituitary gland.
What is the role of LH (luteinising hormone) in the menstrual cycle, and where is it produced?: It stimulates the release of the egg (ovulation); it is produced by the pituitary gland.
Which two hormones, both produced in the ovary, are involved in maintaining the lining of the uterus?: Oestrogen and progesterone.
True or false? On a graph of hormone levels in the menstrual cycle, the peak in LH at about day 14 is caused by a high level of oestrogen.: True. A high oestrogen level stimulates LH release, which triggers ovulation; oestrogen also inhibits FSH.
