Answer 1

Hint: The natural way of preventing pregnancy is believed to be lactational amenorrhea. The lactational amenorrhea method (LAM) was created as a temporary birth control strategy to aid in both family planning and breastfeeding.

Complete Step by Step Answer:
Breastfeeding is generally referred to as a birth control strategy when discussing the lactational amenorrhea method. Even though it is occasionally ineffective, it nevertheless contributes to a decline in the fertility ratio. After giving birth, the women do not experience their menstrual cycle, which significantly lowers their chances of becoming pregnant and causes lactational amenorrhea. There are no adverse effects because it is a natural way of birth control that doesn't include tablets or other medications. However, that does not imply that it is entirely secure. The hormone flow can fluctuate at times, making this approach somewhat ineffective. Menstruation returns at different times for different women, but generally speaking, it takes about six months.
The menstrual or ovarian cycles halt when breastfeeding is initiated. This is brought on by the gonadotropin-releasing hormone's pulsatile release. The hypothalamus releases it, while the pituitary gland releases luteinizing hormone. When the reduced signals of LH lead to the diminished amount of estradiol, the plasma concentration of follicle-stimulating hormone is sufficient to initiate the growth of follicles during the breastfeeding phase. Lactation stops the LH surge once the level of estradiol reaches normal levels. Only when the body's capacity for lactation is reduced does ovulation occur. Thus, the delay in the start of regular ovarian cycles is caused by this lactation. Lactational amenorrhea is a disorder that is frequently linked to hyperprolactinemia. The mechanical sensing of sucking raises the levels of prolactin. As a result, there is an increase in milk synthesis. Thus, an excess of prolactin blocks the menstrual cycle, which is why lactational amenorrhea is intimately related to it.
Looking at all the mechanism stated above. The correct answer to the question is B. All except (vii)

Note: Amenorrhea and hyperprolactinemia in women are frequently linked. The physiological status during lactation is similar to this scenario. As a result of mechanical suckling detection, the body produces more prolactin, which can directly suppress the menstrual cycle by having a suppressive effect on the ovary and indirectly by lowering GnRH release.
