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.

USF study: HHV-6 causes permanent infection by inserting its DNA into human chromosomes

Human herpesvirus 6 (HHV-6) infects nearly 100 percent of humans in early childhood, and the infection then lasts for the rest of a person's life. Now, a team led by Peter Medveczky, MD, a professor in the Department of Molecular Medicine at the University of South Florida, has discovered that in some individuals, HHV-6 causes such a permanent infection by inserting or "integrating" its DNA into human chromosomes.

Usage of gonadotropins in assisted reproductive technologies significantly improves outcomes

The U.S. infertility specialty has empirically incorporated greater amounts of human menopausal gonadotropin (hMG) into stimulation protocols, according to a new review article, "Gonadotropins in the Treatment of Infertility" by George T. Koulianos, MD, published in a recent issue of US Obstetrics & Gynecology, supported by an educational grant from Ferring Pharmaceuticals. The article reviews the wealth of clinical evidence supporting this trend, and demonstrates how the use of gonadotropins in the treatment of infertility, especially in assisted reproductive technologies, has significantly improved outcomes.

'Fertility chip' to accurately count spermatozoa in sperm

A new 'fertility chip', developed by researchers at the University of Twente's MESA+ Institute for Nanotechnology, can accurately count spermatozoa in sperm.

Mouse sperm can discriminate between its brethren and competing sperm, says study

Some mouse sperm can discriminate between its brethren and competing sperm from other males, clustering with its closest relatives to swim faster in the race to the egg. But this sort of cooperation appears to be present only in certain promiscuous species, where it affords an individual's sperm a competitive advantage over that of other males.
