The production of gametes is a biological process occurring in organisms that sexually reproduce. Females make gametes called eggs, and males make gametes called sperm. Both egg and sperm cells begin as identical germ cells and are produced through a process of cell division called meiosis, which...

Today the company Krisiloff started, called Conception, is the largest commercial venture pursuing what’s called in vitro gametogenesis, which refers to turning adult cells into gametes—sperm or egg cells. It employs around 16 scientists and has raised $20 million from well-known tech figure...

A crucial part of meiosis occurs when both strands of DNAbreakin the same place and then are repaired by a process called recombination. About 300 of these double-strand breaks occur around the genome during the normal formation of egg and sperm cells. The breaks ensure that the parents' DNA...
Some cells are set up to become stem cells, which will then have the potential to develop into any type of cell in the body. And some cells in the fetus become primordial germ cells and eventually evolve into the cells of either sperm or eggs, which will allow this offspring to pass th...

Reproductive Technology(ART) began to be popular, freezing or cryopreservation, also known asslow freezing, was the only technique available. Since this method offered high success rates in the case ofsperm cryopreservation, today it continues to be the technique used for preserving sperm cells. ...
