Question

On which of the following facts does the method of periodic abstinence is based?

• A. Ovulation occurs on about the $14^{th}$ day of menstruation
• B. Ovum remains alive for about $1-2$ days
• C. Sperms survive for about $3$ days
• D. All of these

Answer 1

Answer: (D)

Periodic abstinence is a method of contraception in which the couples avoid intercourse from day $10$ to $17$ of the menstrual cycle because ovulation can occur during this period. The chances of fertilisation are high during this period. Ovum remains alive for above $1-2$ days and sperm survives for about $3$ days.
