Question

In the ovarian cycle what role does Luteinizing Hormone (LH) play?

Answer 1

ROLE OF LUTEINIZING HORMONE (LH)

1. In ovarian cycle, various stages are observed for the ovum development.
2. The whole process is controlled b two hormones: FSH (follicle stimulating hormone) and LH (luteinizing hormone).
3. LH hormone stimulated the development of corpus luteum, which secretes progesterone hormone.
4. Progesterone hormone is essential for the preparation of uterus wall for implantation.
5. LH hormone is controlled by the feedback mechanism: as the level of progesterone increases in the blood, it gives negative feedback to the anterior pituitary that stops the secretion of LH.
6. Due to this corpus luteum disintegrates. The whole process is called Luteal phase.
