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.

Study finds microplastics in semen and urine, linking PTFE exposure to lower sperm count

Researchers in China found multiple types of microplastics in human semen and urine, with exposure to PTFE significantly linked to reduced sperm quality, highlighting potential reproductive health risks.

AI model predicts male infertility risk using blood hormone levels

According to a World Health Organization (WHO) study (2017), about half of all infertility is due to men. Semen analysis is considered essential for diagnosis of male infertility, but is not readily available at medical institutions other than those specializing in infertility treatment, and there is a high threshold for receiving it.
