Coloured SEM of human spermatozoa
Bildnummer 11874124
| Sperm cells. Coloured scanning electron micrograph (SEM) of human sperm cells (spermatozoa). These tiny male sex cells are produced in the testes,and are responsible for fertilisation of the female's ovum (egg). Each sperm has a rounded head which contains the male hereditary material (DNA or deoxyribonucleic acid) and a long,whip-like tail that propels it along. Sperm production commences at puberty and is dependent on the male sex hormone testosterone. Some 300 million sperm are released by the male during ejaculation,while the human female usually produces one large egg at a time. Only one sperm cell can fertilise the egg.
