The hormone responsible for maturation of mammary gland tissue is:
progesterone.
testosterone.
prolactin.
estrogen.
The Correct Answer is A
Choice A reason: Progesterone is the hormone that stimulates the development of the alveoli and lobules of the mammary glands during pregnancy. It prepares the breasts for lactation by increasing the number and size of the milk-producing cells.
Choice B reason: Testosterone is the main male sex hormone that is responsible for the development of male reproductive organs and secondary sex characteristics. It has no direct role in the maturation of mammary gland tissue.
Choice C reason: Prolactin is the hormone that initiates and maintains milk production after childbirth. It is secreted by the anterior pituitary gland in response to suckling or nipple stimulation. It does not affect the maturation of mammary gland tissue.
Choice D reason: Estrogen is the hormone that stimulates the growth of the duct system of the mammary glands during puberty and pregnancy. It also promotes the development of female reproductive organs and secondary sex characteristics. It does not affect the maturation of mammary gland tissue.

Correct Answer is A
Explanation
Choice A reason: A miscarriage is defined as a spontaneous abortion of a fetus before the 20th week of gestation. It is a natural pregnancy loss that occurs before labor begins and is usually caused by chromosomal abnormalities, infections, or maternal health problems.
Choice B reason: A miscarriage is not often attributed to careless maternal behavior such as poor nutrition or excessive exercise. These factors may affect the quality of life of the mother and the fetus, but they are not the main causes of miscarriage. Most miscarriages are not preventable and are not the fault of the mother.
Choice C reason: A miscarriage that occurs before the 12th week of pregnancy may manifest only as moderate discomfort and blood loss, but this is not always the case. Some women may experience severe cramping, bleeding, and tissue passing from the vagina. Others may have no symptoms at all and only discover the miscarriage during a routine ultrasound.
Choice D reason: A miscarriage occurs in more than 5% of all clinically recognized pregnancies. The actual rate of miscarriage is estimated to be 10% to 20%, but many women may not realize they are pregnant or may not report the loss to their health care provider.
