Question

Which of the following is the component of oral pills?
(a) Progesterone
(b) Oxytocin
(c) Relaxin
(d) None of these.

Answer 1

Hint: This hormone makes the endometrium for the potential of pregnancy after ovulation. It triggers the lining to thicken for accepting an embryo. It also prohibits the muscle contractions within the uterus that might cause the body to reject an egg.

Complete step by step answer:
Oral pills contain either progesterone alone or a mixture of progesterone and estrogen. The most commonly used progesterone is Levonorgestrel. Progesterone inhibits LH production. An example of progesterone pills is i-Pills and Unwanted-72.
So, the correct answer is, ‘Progesterone.’

Additional Information: Any approach used to prevent the conception of unwanted pregnancy refers to contraception. Major contraceptive methods are categorized as barrier methods, surgical and chemical methods.
Barrier methods are the physical devices that prevent contraception by inhibiting the entry of sperms in the female genital tract. Example: condoms, diaphragms, cervical caps, etc.
Surgical methods include vasectomy (blocks vas deferens to prevent sperms from coming out) and tubectomy (blocks fallopian tubes to prevent the entry of eggs in it) in males and females respectively.
Chemical methods of contraception include any hormonal preparation that serves to alter the hormonal balance of the body to prevent egg maturation or fertilization. For example, oral and vaginal pills.
Other methods include intrauterine devices (inserted by a physician into the uterus to prevent implantation), medical termination of pregnancy, coitus interruptus, etc.

Note: The main action of the oral contraceptive pill is the inhibition of ovulation by suppressing the discharge of FSH and LH from the anterior pituitary gland.
There are other actions also, like, progesterone thickens the cervical mucus and makes sperm penetration difficult, it even has an effect on the uterine lining and makes implantation difficult. Estrogen increases the speed of ovum transport and reduces fertilization time.
