  2. Luteinizing hormone - Wikipedia

    en.wikipedia.org/wiki/Luteinizing_hormone

    The increase in LH production only lasts for 24 to 48 hours. This "LH surge" triggers ovulation, thereby not only releasing the egg from the follicle, but also initiating the conversion of the residual follicle into a corpus luteum that, in turn, produces progesterone to prepare the endometrium for a possible implantation. LH is necessary to ...

  3. Corpus luteum - Wikipedia

    en.wikipedia.org/wiki/Corpus_luteum

    The corpus luteum is colored as a result of concentrating carotenoids (including lutein) from the diet and secretes a moderate amount of estrogen that inhibits further release of gonadotropin-releasing hormone (GnRH) and thus secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

  4. Hypothalamic–pituitary–gonadal axis - Wikipedia

    en.wikipedia.org/wiki/Hypothalamic–pituitary...

    The corpus luteum's lifespan is influenced by LH pulse frequency and amplitude, gonadotropin levels, and luteotropic factors like prolactin, oxytocin, and prostaglandins. Luteolysis involves factors such as endothelin-1 and TNFα, which inhibit steroidogenesis and induce apoptosis.

  6. Activin and inhibin - Wikipedia

    en.wikipedia.org/wiki/Activin_and_inhibin

    Inhibin is produced in the gonads, pituitary gland, placenta, corpus luteum and other organs. FSH stimulates the secretion of inhibin from the granulosa cells of the ovarian follicles in the ovaries. In turn, inhibin suppresses FSH. Inhibin B reaches a peak in the early- to mid-follicular phase, and a second peak at ovulation.

  8. Folliculogenesis - Wikipedia

    en.wikipedia.org/wiki/Folliculogenesis

    Inhibin, which is also secreted by the corpus luteum, contributes to FSH inhibition. Progesterone, secreted by the corpus luteum, inhibits the follicular growth and maintains the pregnancy. The endocrine system coincides with the menstrual cycle and goes through thirteen cycles (and thus thirteen LH spikes) during the course of normal ...

  9. Menstrual cycle - Wikipedia

    en.wikipedia.org/wiki/Menstrual_cycle

    Menstrual cycle The menstrual cycle is a series of natural changes in hormone production and the structures of the uterus and ovaries of the female reproductive system that makes pregnancy possible. The ovarian cycle controls the production and release of eggs and the cyclic release of estrogen and progesterone. The uterine cycle governs the preparation and maintenance of the lining of the ...
