A little physiology
In order for the embryo to form, two sex cells are required - a female egg and a male sperm cell. Only in the presence of these two components comes pregnancy. Scientists have not yet found any artificial substitute for one or the other. Given this, one way or another, a woman needs a man, although in some cases you can do without traditional sexual intercourse.
How can you get pregnant without a man?
So, the answer to the question of whether a woman can become pregnant without a man in the 20th century has become positive. Back in the forties, scientists began to work on fertilizing the egg with sperm outside the female body. After this, numerous attempts were made to insert the embryo into the female womb and in 1978 they were crowned with the long-awaited success.
Thanks to the perseverance of scientists, now a woman, wishing to become pregnant, can not look for her child's father, if she is not married. To do this, there is a sperm bank, which will select a donor material that meets the requirements of the future mother.
But how to get pregnant without a man and without an IVF is a problem and unresolved, and it is unlikely ever that a woman, like the Virgin Mary, conceived from the Holy Spirit.
