The term sperm refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

Participation project calls for relaxing research ban on germline interventions

Are genetic defects allowed to be repaired by intervening with sperm or egg cells, or even human embryos? Thanks to genetic scissors such as CRISPR/Cas, such interventions in the germline could soon become a medical reality.

Study finds undiagnosed prediabetes in many infertile men

In a study of 744 infertile men, prediabetes was found in 114 (15.4 percent) of participants. Certain factors were linked with prediabetes in the BJU International study, and they might be useful markers for identifying men who could benefit from early preventive interventions to safeguard against the development of diabetes.

Study investigates prevalence and causes of multiple pregnancies after single embryo transfer

It has been known for some time that it is better to transfer a single embryo to a woman's womb during assisted reproduction treatment (ART) rather than several embryos in order to avoid a multiple pregnancy and the risks associated with it such as fetal deaths, miscarriage, premature delivery and low birthweight.
