Let us know about conception-
Conception is the iniciation of pregnancy or union/fusion of Spermatozoon ( male gamet) & ovum (female gamet) at the ampulary part of uterine /fallopian tube to form a Zygot,(single cell) ..Zygot contains both the paternal& maternal genetic materials Zygot rapidly starts dividing, growing & ultimately become new baby. So,life starts from the Zygot.
We have to know the sources of spermatozoon & ovum. Testicles & ovaries are the source of male & female gamet respectively.Testiclec are two glands lying within the male scrotum( Normal site) On the other hand,Ovaries are 2 small oval shaped female organs attached to either side of uterus
The Gender of a baby depends on which type of sperm fertilise (meet /unite/fuse) the egg.Sperm with Y chromosome will make a boy baby.& Sperm with a X chromosome will make a girl baby.So, it is the male partner of a couple is responsible for boy or girl baby. We should bear this concept in mind & give up blaming female for girl baby.It is also helpful to avoid remarry many womens or divorce the existing female by males.
