Luteinising hormone (LH) stimulating the release of the egg.
Oestrogen and progesterone are involved in maintaining the uterus lining.
Follicle stimulating hormone (FSH), causing maturation of an egg in the ovary.
Sex hormones are responsible for driving sexual development (puberty). The main reproductive hormones are oestrogen and testosterone.
Events of the female hormonal cycles
the follicular phase
The follicular phase starts on the first day of menstruation and ends with ovulation. Prompted by the hypothalamus, the pituitary gland releases follicle stimulating hormone (FSH).
Ovulation is the release of a mature egg from the surface of the ovary. This usually occurs mid-cycle, around two weeks or so before menstruation starts.
Menstruation is the elimination of the thickened lining of the uterus (endometrium) from the body through the vagina. Menstrual fluid contains blood, cells from the lining of the uterus (endometrial cells) and mucus.
If a fertilised egg implants in the lining of the uterus, it produces the hormones that are necessary to maintain the corpus luteum. This includes human chorionic gonadotrophin (HCG), the hormone that is detected in a urine test for pregnancy
Anatomy of male and female reproductive structures;
This is the male organ used in sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped part at the end of the penis.
These are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes.
This is the loose pouch-like sac of skin that hangs behind and below the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels.
The uterus is a hollow, pear-shaped organ that is the home to a developing fetus
The ovaries are small, oval-shaped glands that are located on either side of the uterus. The ovaries produce eggs and hormones
The vagina is a canal that joins the cervix (the lower part of uterus) to the outside of the body.
These are narrow tubes that are attached to the upper part of the uterus and serve as tunnels for the ova (egg cells) to travel from the ovaries to the uterus.
