First Let’s begin by women who are still waiting for a child, who have waited for a long period of time, suffered several child miscarriages, still births and are trying to find every alternative medium of having a child at all cost
In my culture (Ukuwani) it is really difficult to talk about this as people are ashamed or don't know who to trust and are just generally confused, and longed to be a mother someday. The issues of child birth in most region of the world especially Nigeria, it is termed as witchcraft if after 2 to 3 years of marriage no child.
It is believed in Nigeria after 2 years and no child birth you have major issues especially from your village, or from your family members. but i know that is not always true, only in rare cases its true, with an aggregate of 10%.
Many factors might as well affect the issues of child birth, scientifically if a male and female are physically fit, they have 75% chance of child birth. Most action such as intimate sex, low sperm count, high rate of virgina discharge and rare cases according to a common man witchcraft, might as well be responsible for child birth.
This writing all boils down to, Child birth is way beyond just having sex and producing babies, it’s mystery, science only state that child comes from sexual intercourse, but has no prove for the birth of the savior. and it comes when it’s the appropriate time, I think its high time women are not called barren, flowerless, they are blessing, they bleed for us to live.
