Question 3. Describe The Usage Of Estrogen.
Answer:

The following are the oral contraceptives:

• Combined pill
• Mini pill
• Postcoital pill.

Estrogen Combined Pill

• It is the combination of estrogen and progestin preparations.
• Ethinyl estradiol (30 to 50 mg) is the estrogen used. Progestins such as desogestrel and norgestimate are used.
• The combined pill should be started on the 5th day of the menstrual cycle and is taken daily for 21 days with a gap of 7 days during which bleeding occurs. This is a monophasic regimen.
• Mechanism of action: Estrogen and progestin act synergistically on hypothalamopitutary axis through a negative feedback mechanism and stop the release of follicular stimulating hormone and luteinizing hormone which makes inhibition of ovulation.
  This leads to tubal and uterine contractions which interfere with fertilization. This makes endometrium less suitable for implantation. The thick cervical mucus secretion prevents the penetration
  of sperm.

• This pill should be taken without any gaps.

• Its efficacy is low and the menstrual cycle can be irregular, so this pill is not popular in its use.
