luteinizing hormone (LH) from the pituitary gland
- gonadotropinreleasing hormone (GnRH) is firs produced in the brain by the hypothalamus.
- The pituitary gland is then triggered by this to release the follicle stimulating hormone (FSH).
- The FSH is transported to the ovaries, via the bloodstream where it starts the growth of a follicle.
- Upon the development of the follicle estrogen starts being produced.
- After approximately 10 days, the estrogen levels become high.
- Estrogens peak about a day before ovulation. This would be day 13 in a normal 28 day cycle.
- This peak bring about a surge of luteinizing hormone (LH) from the pituitary gland.
- This surge acts a cue for the ovarian follicle to release a mature ovum into the fallopian tube leaving behind corpus luteum or the empty follicle.
- The cells of the corpus luteum produce progesterone and estrogen
- The uterine lining is stimulated to thicken with blood by these two hormones to prepare them for the nurturing of the fertilised egg.
- The corpus luteum starts to diminish and leaves uterine lining with no hormonal support.
- The lining starts to shed off
- females monthly menstrual cycle starts again.
Low levels of estrogen and progesterone also signal the hypothalamus to start the process over again.
