Sex cells – eggs and sperm – are produced through meiosis, a form of cell division. During meiosis, a chromosome pair from the father and another from the mother swap sections of their DNA. This recombination, which requires double-strand breaks in the chromosomal DNA, creates a new combina...

A transplantation assay demonstrated that the in vitro-expanded GSCs exhibited stem cell activity and potency to produce functional eggs, sperm, and eventually healthy offspring. In vitro expansion of GSCs can aid in rescuing fishes that are on the verge of extinction....
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...
Many people will need sperm, embryo, or egg donation to help them start their family. Donors give people the chance to experience the joy of children and share in the gift of life.
It is possible that eggs are more attracted to genetically compatible sperm, which may increase the chance that they are fertilised, says Fitzpatrick. The chemical interactions between eggs and sperm after sex may also play a role in why some people have difficulty conceiving. In around ...

who were attempting to become pregnant via in vitro fertilisation, and who had been given hormonal drugs to cause them to ‘superovulate’ or produce several mature eggs at once. The finding that the attractiveness of follicular fluid to sperm varied ...
They mated the birds that had the highest levels of the beta-lactamase gene in their own egg and sperm cells and produced birds that reliably carried working copies of the gene. Several generations of these chickens laid eggs that carried the gene, Harvey's team reported. ...
