The hypothalamus secretes a small peptide, gonadotropin-releasing hormone (GnRH), also known as luteinizing hormone–releasing hormone. GnRH regulates release of the gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from specialized cells (gonadotropes) in the anterior pituitary gland (see figure The CNS-hypothalamic-pituitary-gonadal target organ axis ).

The follicular phasemarks the beginning of a new cycle as follicles (oocytes surrounded by stromal cells) begin to mature and prepare to release an oocyte. At the start of a new cycle (menses), there is little ovarian hormone production and the follicle begins to develop independently of gonadotropins or ovarian steroids. Due to the low steroid and...
In response to the LH surge, the follicle ruptures and the mature oocyte is assisted to the fallopian tube by fimbria. Here it remains viable for fertilisation for around 24 hours. Following ovulation, the follicle remains luteinised, secreting oestrogen and now also progesterone, reverting back to negative feedback on the HPG axis. This, together ...
The corpus luteumis the tissue in the ovary that forms at the site of a ruptured follicle following ovulation. It produces oestrogens, progesterone and inhibin to maintain conditions for fertilisation and implantation. At the end of the cycle, in the absence of fertilisation, the corpus luteum spontaneously regressesafter 14 days. There is a signif...

The menstrual cycle requires precise coordination between several processes in the body. 1, 2 The major components of this control system include the hypothalamic gonadotropin-releasing hormone (GnRH) pulse generator, the pituitary gonadotropes, the ovaries, and the uterus. The gonadotropes respond to GnRH pulses by releasing the gonadotropins, follicle-stimulating hormone (FSH), and ...
Jan 17, 2023 · Key Terms. estrogen: A hormone responsible for the appearance of secondary sex characteristics of human females at puberty and the maturation and maintenance of the reproductive organs in their functional state. cumulus: A cluster of cells that surround the oocyte both in the ovarian follicle and after ovulation. These cells.
Jul 30, 2022 · Hormone therapy (HT), which employs medication (synthetic estrogens and progestins) to increase estrogen and progestin levels, can alleviate some of the symptoms of menopause. In 2002, the Women’s Health Initiative began a study to observe women for the long-term outcomes of hormone replacement therapy over 8.5 years.

Aug 22, 2024 · Female anatomy includes the internal and external structures, including those responsible for hormones, reproduction, and sexual activity. The female reproductive system is essential for hormone regulation, sexual pleasure, pregnancy, breastfeeding, and more. The main parts of the female anatomy can be broken up into external and internal parts.
