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.

Researchers unmask functioning of protein involved in DNA repair during spermatogenesis

Researchers from the Department of Cell Biology, Physiology and Immunology and the Institute for Biotechnology and Biomedicine of the Universitat Autònoma de Barcelona have unmasked the functioning of a protein involved in DNA repair, ATR, in the meiotic recombination process which takes place during the development of spermatocytes - sperm precursor cells- and how inhibiting this protein causes anomalies which block spermatogenesis.
