If you thought everyone knew how babies are made: you will be surprised by the numbers who don’t really know. Making a baby, does require both a male and a female human being. Or to put it simply: a male sperm and a female oocyte
The female supplies the egg, one of which is released, every month, by the ovary (the organ that produces eggs). The egg is swept up by the fronds or fimbria at the end of the fallopian tube. The fallopian tube is a trumpet shaped tube with its wide mouth located near the ovary to pick up released eggs and it’s other narrow end opening into the upper corner of the uterus. There are two fallopian tubes, one on either side of the uterus, stretching out to the ovary of that side. The egg travels along the canal of the fallopian tube and reaches the middle part of the tube. Here it awaits the arrival of the sperm. The male supplies the sperms, generally released in millions, at each ejaculation. When ejaculation occurs inside the vagina, the semen which contains millions of motile or moving sperms is released into the vagina. The sperms can swim up from the vagina up the cervix and the uterus and finally reach the fallopian tube. If a sperm meets an egg in the tube and they unite, fertilization is said to have happened and an embryo or new human being is formed.
On the other hand, in assisted reproduction, or test tube baby formation, the egg and the sperm unite in the laboratory, under the watchful eye of the embryologist peering through the microscope.
