It was shown that the factors that can have the biggest impact on the quality of sperm cells are smog, smoking, varicocele, diabetes, testicular tumours, and ageing. Scientists have determined the main risk factors that can lower sperm quality and increase infertility. Researchers from Semmelweis University in Budapest, Hungary, have pinpointed the most perilous elements […]
One form of fertility treatment may raise long-term cancer risk in offspring
Prior studies have suggested that children born after frozen-thawed transfer may have higher short-term health risks, but long-term risks have been less clear. Children born as a result of a common fertility procedure involving frozen embryos may have higher risk of cancer, Swedish researchers report. In frozen-thawed embryo transfer, an embryo is created in a laboratory from […]
Bypassing the requirement for sperm, eggs, and fertilisation, Israeli scientists create the first “synthetic embryos” in history
The ability to induce mouse stem cells to self-assemble into structures resembling early embryos with a digestive tract, a developing brain, and a beating heart was found by scientists at the Weizmann Institute in Israel. Some cells underwent chemical pretreatment to activate genetic programmes that would drive them to develop into the yolk sac or […]
Continuous sperm production is made possible by a newly discovered stem cell self-renewal factor
The discovery was documented in the publication Genes and Development. Men can continue to generate sperm throughout their adult life, in contrast to women who are born with all the eggs they will ever have. They must continually replenish the spermatogonial stem cells that give rise to sperm in order to do this. According to […]
