Question

Which hormone is responsible for the maintenance of pregnancy?
(a)HCG
(b)Progesterone
(c)Estrogen
(d)Prostaglandin

Answer 1

It is secreted by the feminine genital system that functions mainly to manage the condition of the inner lining (endometrium) of the uterus. During pregnancy, it also stimulates the development of the glands in the breasts that are responsible for milk production.

Complete answer:
Progesterone is produced from the corpus luteum, which is the small gland that forms in the ovary after ovulation has occurred. This hormone is important for the upkeep of pregnancy and also for the event of the many symptoms during early pregnancy.

Additional Information: It also inhibits muscular contractions of the uterus that might probably cause the wall to reject the adhering egg. An embryo that becomes implanted within the uterus will form a placenta. The placenta then produces progesterone during the amount of pregnancy. If the egg isn't fertilized, progesterone is secreted by the ovaries until a couple of days before menstruation, at which era the extent of progesterone drops sufficiently to prevent the development of the uterine divider and to make it begin to separate, and monthly cycle results.
So the correct answer is ‘Progesterone’.

Note: Progesterone is known to have effects on other female organs. In the ovaries, progesterone and estrogens are thought liable for the discharge of an egg during ovulation. It is accepted that if the egg is fertilized, these hormones are persuasive inside the avoidance of additional egg discharge until the pregnancy has ended. This dual-action ordinarily prevents the discharge and fertilization of quiet one egg at just one occasion, although two or more eggs are occasionally released. In the fallopian tubes, progesterone is assumed to prevent the muscular contractions within the tube once the egg has been transported.
