Question

'Safe period', a means of birth control is based on:
A) Ovulation which occurs on the 14th day of menstrual cycle.
B) Ovum which survives for about 2 days.
C) Sperms which remain alive for about 3 days.
D) All of the above

Answer 1

Hint: Subtract 18 days from the length of your shortest cycle to determine the first day of your reproductive window. For instance, if your shortest cycle was 27 days, take 18 off of that number, then note day 9. By taking 11 off the duration of the longest cycle, you may determine the final day of your reproductive window.

Complete Step by Step Answer:
The day your menstrual flow starts, your menstrual cycle resets. The follicular phase, during which the egg develops and is later released during ovulation, begins at this time.
Follicle-stimulating hormone (FSH), which is released by your body during the follicular phase, aids in the maturation and preparation of the egg in your ovary for release.
When the egg is fully developed, your body produces a large amount of luteinizing hormone (LH), which causes the egg to be released. Around day 14, between 28 and 36 hours after the LH spike, ovulation typically takes place.
Luteinization occurs after ovulation. In the event of pregnancy, hormones will prevent the lining from shedding. If not, bleeding will begin on or around day 28 of the cycle, starting the following cycle.

Hence, option D is the correct answer.





Note: In order to prevent ovulation, couples who utilise the practise of periodic abstinence refrain from sexual activity from days 10 to 17 of the menstrual cycle. During this time, fertilisation chances are very high. Ovums can live for more than a day and a half, whereas sperm can last for roughly three days.
An egg cell can only survive after ovulation for 12 to 24 hours. The fertile window lasts a total of six days because sperm can survive in the female body for up to five days.
