Write down the name of hormones secreted by the ovary in the later phase of pregnancy.

Answer 1

Progesterone is the hormone thickening of the uterine lining for implantation of a fertilized egg, and made by the ovaries and placenta during the pregnancy. Progesterone belongs to a group of steroids and secreted with the help of corpus luteum in the second half of the menstrual cycle and also helps to maintain the early stage of the pregnancy.

Complete answer:
The primary sex organ present in the females are ovary that produces two main steroid hormones such as progesterone and estrogen.

Progesterone: -The progesterone synthesized from cholesterol and produced by the main source placenta, testes and adrenal glands. Luteal cells of the corpus luteum and adrenal cortex and placenta is the main source of the production progesterone. The endometrial glands (uterine milk) for the nutrition of the ovum and attachment of the embryo cause growth of the glandular system that’s present in the progesterone. And also help to maintain the pregnancy and provide a favorable environment for survival of the embryo.
Estrogen: - The function of the estrogen is development of the reproductive organs and maturation growth of the uterine muscle. And increase the vascularity of the uterus and development of the endometrial lining of the uterus. With the help of estrogen uterus is less susceptible to infection because of the dilation cervix, and liquefaction of mucous plug.

Note: The continued production of the progesterone by the human chorionic gonadotropin embryonic hormone that is present in the corpus luteum wall of the uterus. Progesterone and relaxing hormones only found in the female reproductive system. These hormones exert their actions on the female mammary gland and genital tract.
