Answer 1

Hormones primarily monitor fertility and menstruation, and progesterone is one of many hormones. Progesterone belongs to the family of hormones called progestogens and is a steroid hormone. The corpus luteum, a temporary endocrine gland developed by the female body after ovulation during the second half of the menstrual period, secretes it.

Complete step by step answer:
To prevent pregnancy, oral contraceptives are used. Women's sexual hormones are oestrogen and progestin. By suppressing ovulation (the release of eggs from the ovaries), combinations of oestrogen and progestin work. To prevent pregnancy from progressing, they also change the uterine lining (womb) and modify the mucus at the cervix (opening of the uterus) to stop sperm (male reproductive cells) from entering. Oral contraceptives are a really effective birth control tool. Progesterone-only pills primarily serve by preventing ovulation, thinning the endometrium and stiffening the mucus of the cervix, blocking the entry of sperm into the uterus. The progesterone-only pill requires two days to stiffen cervical mucus such that sperm can't get through or thrive.

So, correct answer is option (A).

Additional Information:
Two forms of progesterone-only pills prevail: (i) Progesterone-only 3-hour pill (traditional progesterone-only pill) must be taken every day within three hours of the same time. (ii) The 12-hour progesterone-only pill (desogestrel progesterone-only pill) should be given at the same time every day within 12 hours. Some allergic events include: Acne, tenderness of breasts and breast enlargement, an increased or reduced sex drive, mood changes and Illness or vomiting.

Note:
For some patients, certain types of oral contraceptives are often used to treat acne. By decreasing the amounts of certain natural substances that can cause acne, contraceptive pills treat acne. In women who have preferred to use an oral contraceptive to prevent pregnancy, some oral contraceptives are used to alleviate symptoms of premenstrual dysphoric disorder (physical and emotional symptoms that develop before the menstruation each month).
