If you're male, your body uses meiosis to create sperm cells; if you're female, it uses meiosis to create egg cells. Others cells in your body contain 46 chromosomes: 23 from your father and 23 ...

In the United States, more than 11% of men under the age of 49 are infertile. While the causes are varied and range from ...

The four gametes produced in meiosis are genetically different ... During fertilisation the haploid nucleus of a sperm cell and the haploid nucleus of an egg cell fuse together to form a diploid ...

Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid ... through a type of cell division called meiosis. During meiosis, a diploid parent cell ...

Meiosis is the generation of germ cells (eggs and sperm). In meiosis, DNA replication is followed by two division cycles: meiosis I, which segregates homologous chromosomes and meiosis II ...

They are formed in a woman's body before birth and have to be on standby for decades to possibly be fertilized one day. But ...

A genetic mutation in mice affects cells required for sexual reproduction and holds clues about male infertility that could ...

Katanin plays other roles. When a sperm fertilizes an egg, the maternal cell has not yet finished meiosis. It still has two of each chromosome and must separate those chromosome pairs and discard ...

However, they are also essential for meiosis—the process of forming sperm and egg cells. In the latter situation, DSBs are intentionally introduced to allow genetic recombination by mixing ...

In a potential breakthrough for infertility and genetic disease treatments, scientists at Kyoto University have succeeded in mass-generating precursors to sperm and eggs from human iPS cells. Two ...

While the causes are varied and range from infections to hormonal imbalances, deformities during meiosis – a specialized cell division process that creates sperm and eggs – is a leading cause.
