Question

Answer

When the production of progesterone and estrogen hormone stops in blood this leads to shed off the lying of uterine endometrium.

Progestrone and estradiol continue the hypertrophy of endo metrial lining in the uterus and fallopian tubes and maintain it throughout pregnancy.

Progesterone is also necessary for the proper implanation of the foetus in the uterine wall. It stimulates the endometrial glands to secrete a nutrient fluid for the foetus, hence the term secretory phase.

Therefore, by supply of estrogen and progesterone the menstruation can be deferred.

Answer

Combination of Estrogen and Progesterone
In the human female body, menstruation can be deferred by the administration of a combination of estrogen and progesterone. This combination of hormones is commonly known as hormonal contraceptives or birth control pills.

Estrogen and Progesterone Role
- Estrogen and progesterone are the two main female sex hormones that play a crucial role in the menstrual cycle.
- Estrogen helps regulate the growth of the uterine lining during the first half of the menstrual cycle, while progesterone helps maintain the uterine lining in preparation for a potential pregnancy during the second half of the cycle.

Mechanism of Action
- When a woman takes hormonal contraceptives containing estrogen and progesterone, it mimics the natural hormonal levels in the body.
- These synthetic hormones prevent ovulation, thicken the cervical mucus to prevent sperm from reaching the egg, and thin the uterine lining to make it less receptive to implantation.

Effect on Menstruation
- By regulating the hormonal levels in the body, estrogen and progesterone in birth control pills can effectively defer menstruation.
- The hormones prevent the natural hormonal fluctuations that trigger menstruation, leading to lighter periods or even the absence of menstruation altogether.

Consultation
It is important for women to consult with a healthcare provider before starting hormonal contraceptives to determine the most suitable option based on their individual health needs and medical history.
