If ovaries from a pregnant woman are removed in 4th month of pregnency then :-a)Development of embryo becomes abnormalb)Abortion occurs after some timec)Embryo develops normally till birthd)NoneCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Ya,C is correct because after 6 weeks enough secretion of projestron, estrogens is started from placenta, so during this time if we cut the overt then it will be no effect on embryo.

Answer

By the first trimester the Placenta is fully developed and is able to secrete hormones like progesterone that are essential for the maintenance of pregnancy. During the development of placenta ovaries produce these hormones.

Answer

Answer:

Removing the ovaries from a pregnant woman in the fourth month of pregnancy will not result in abnormal development of the embryo or abortion. The correct answer is option 'C', where the embryo develops normally until birth.

Here is an explanation of why this is the correct answer:

1. Ovaries and Pregnancy:
The ovaries in a woman's reproductive system play a crucial role in pregnancy. They produce and release eggs, as well as hormones such as estrogen and progesterone. These hormones are necessary for the development and maintenance of the pregnancy.

2. Hormonal Support:
During the first trimester of pregnancy, the hormones necessary for maintaining the pregnancy are mainly produced by the corpus luteum, a temporary structure formed in the ovary after ovulation. By the fourth month of pregnancy, the placenta takes over the production of hormones, including estrogen and progesterone, which are necessary for the normal development of the embryo.

3. Placental Hormone Production:
The placenta is a temporary organ that develops during pregnancy. It is responsible for providing oxygen and nutrients to the growing embryo and fetus, as well as removing waste products. Additionally, the placenta produces hormones that are essential for maintaining the pregnancy, such as human chorionic gonadotropin (hCG), estrogen, and progesterone.

4. Hormone Transfer:
Even if the ovaries are removed, the placenta continues to produce the necessary hormones for maintaining the pregnancy. These hormones are transported through the bloodstream to the uterus, where they support the growth and development of the embryo.

5. Embryo Development:
The development of the embryo is not solely dependent on the ovaries. After the fourth month of pregnancy, the major organ systems of the embryo have already formed, and the placenta takes over the role of hormone production and nutrient exchange. As a result, the embryo can continue to develop normally until birth, even if the ovaries are removed.

In conclusion, removing the ovaries from a pregnant woman in the fourth month of pregnancy will not result in abnormal development of the embryo or abortion. The placenta takes over the role of hormone production, ensuring the normal development of the embryo until birth.
