LUTEINZING HORMONE –LH
LUTEINIZING HORMONE (LH) IN FEMALES
- This hormone is also known as Interstitial Cells Stimulating Hormone (ICSH).
- It causes the final maturation of Graafian follicle and stimulates ovulation.
- Stimulates secretion of estrogen by the theca and granulosa cells.
- It helps in the formation and development of corpus luteum for luteinization of cells.
- In conjunction with luteotropic hormone (LTH), it is concerned with the production of estrogen & progesterone by the corpus luteum.
- In the ovary it can stimulate the non germinal elements, which contain the interstitial cells to produce the androgens, androstenedione, DHEA and testosterone

- It is necessary for final follicular growth and ovulation.
- Without this hormone, even though large quantities of FSH are available, the follicle will not progress to the stage of ovulation.
- LH acts synergistically with FSH to cause rapid swelling of the follicle shortly…
