Return of feility is delayed after cessation of oral contraception by : 
Select and explain. 
A. 2 weeks, B. 3 weeks, C. 4 weeks, D. 6 weeks
D: 6 weeks
Answer: D: 6 weeks 
Explanation: Ans. is d i.e. 6 weeks Friends, no where it is exactly mentioned when feility returns after cessation of OCP's I am quoting what various books say Dutta : ovulation returns within 3 months of the drug stoppage in 90% cases. Shaw : 90% of women will have normal menstrual cycles within 6 months of stopping OCP, but return of feility may be slightly delayed on account of delayed return of ovulation. Since 6 weeks is the maximum time given in the options, I am going for it.
