A) 9th to 11th days
B) 11th to 18th days
C) 16th to 24th days
D) 18th to 35th days

Answer 1

Hint:The monthly series of changes a woman's body undergoes in preparation for the likelihood of pregnancy. Every month the ovary releases an egg. This process is called ovulation.

Complete answer:
To answer this question, we must know about the risk period in the menstrual cycle.

The danger period refers to the time duration during which there are maximum chances of fertilization and consequent pregnancy. In a normal cycle of 28 days, both LH and FSH attain a peak level within the middle of the cycle that's the 14th day. Secretion of LH ends up during the mid-cycle called LH surge. This induces the rupture of Graffian follicle resulting in the discharge of ovum or ovulation.

If the cycle is of 35 days, the LH and FSH will attain peak level within the middle of cycle around 16th or 17th day and hence ovulation should occur on 16th or 17th day after which egg will be available in oviduct for fertilization for twenty-four hours. The chance of conception is highest around the middle of the cycle.

So the correct answer is option (C). If the menstrual cycle is 35 days then the risk period is 16th to 24th days.

Note:The menstrual cycle varies from female to female. The normal cycle ranges from 21 days to 35 days. The Luteinizing hormone and the follicle stimulating hormones are produced by the pituitary regulates the menstrual cycle. They stimulate ovaries to produce estrogen and progesterone.
