Menopause, the period in a woman’s life during which the menstrual cycle
ceases, is likely to occur between ages 45 and 55.
The ovaries are no longer responsive to the gonadotropic hormones produced
by the anterior pituitary, and the ovaries no longer secrete estrogen or
physical symptoms, such as “hot flashes” (caused by circulatory
irregularities), dizziness, headaches, insomnia, sleepiness, and depression.
Milk production by the breasts, called lactation, is regulated by the
interactions of four hormones :-
Estrogen and progesterone are produced by the ovaries and placenta; they
stimulate proliferation of breast tissue .
- Prolactin and oxytocin are produced by the pituitary :-
•Prolactin causes milk secretion after the breasts have been stimulated by
estrogen and progesterone
•Oxytocin causes contraction of specialized cells, which help relasing milk
Breast-feeding stimulates Prolactin secretion; the resulting high prolactin level
causes changes in the mother's menstrual cycle .
The prevention of pregnancy is termed contraception ('against conception')
and can be accomplished by 3 number of means, such as intrauterine
devices_(UIDs), spermicidal agents, birth control pills, or shields such as a
Sterilisation of the male can be accomplished through a vasectomy. The
vas deferens are the tubes that carry the sperm into the urethra, and tying
off these tubes prevents the sperm from travelling out of the penis during
sexual intercourse. Females may be sterilised via tubal ligation. The
Fallopian tubes are cut or tied shut preventing the egg from travelling from
the ovary to the uterus.

5- Breast cancer :- is one of the leading causes of death in woman between
the ages of 32 and 52 , Men can also get breast cancer but at a lower rate,
and it was estimated that there were about 1000 cases of male breast cancer
