Fertility is the capability to conceive or to capability to get pregnant through normal sexual activity.Fertility rate can be measured to find out the the number of children born in each couple, person, or a certain populace. Fecundity is not like fertility rate which means potential for reproduction. Infertility is deficient fertility.it is the inability to be with child.  Human fertility depends on factors of nutrition, sexual behavior, culture, instinct, endocrinology, timing, economics, lifestyle, and emotions.

The hormonal cycles of men and women would tell when the woman would more likely get pregnant and when the man would be virile enough. Women’s fertility cycle is estimated to go the whole 28 days while the male’s fertility cycle can be changeable. In any time of the month, a man can produce many sperms but the quality of it differs irregularly depending on his internal cycle.Age is also a significant factor especially for women.

A woman has to ovulate to be able to be with child.   A mature egg must be discharged from one of her ovaries and her male partner must ejaculate millions of mature, fertile sperm. As the sperm goes through the ovaries and goes to the uterus, it should be rich and able to penetrate the egg. The fertilized egg should be able to divide numerous times, implant in the uterus, and form the placenta that is its lifeline until birth.

Women can go pregnant at all times in their menstruation cycle but the peak of it is into a few days in the cycle.  Usually it’s two days before and two days after the ovulation date. Fertility varies in every woman same as the ovulation period varies from every cycle in each woman. It usually takes forty-eight hours for the ovule to fertilize after it is released from the ovary. Sperm continues to exist inside the uterus between the averages of forty eight to seventy two hours, with the maximum time being five days or one hundred twenty hours.
