| 설명 | 남성의 성숙된 생식 세포. 고환에서 생성되며 정관을 통해 배출된다. 고환내의 정세관에서 생성되며 정자 발생과 정자 형성의 두 과정으로 이루어짐. ① 정자 발생은 사춘기가 되면 뇌하수체 전엽에서 분비되는 난포 자극 호르몬에 의해 정자가 만들어지기 시작함. 정조세포(spermatogonia, 23쌍 염색체)→일차정모세포(primary spermatocyte, 23쌍, 4N DNA)→이차정모세포(23, 2N DNA)→정자세포(23, 1N DNA)→정자(23, 1N DNA)  |

| invasion | A term that should be used with caution, although most cell biologists would follow Abercrombie in meaning the movement of one cell type into a territory normally occupied by a different cell type, some pathologists might not agree. (18 Nov 1997) |
| invasion index | An index devised by Abercrombie & Heaysman as a means to estimate the invasiveness of cells in vitro. The index is derived from measurements on confronted explants of the cells and embryonic chick heart fibroblasts growing in tissue culture: it is the ratio of the estimated movement, had the cells not been hindered and the actual movement in the zone in which collision occurs. (18 Nov 1997) |
| sperm | A reproductive cell produced by the male of an animal species which, when united with an egg (of the same species), results in conception and the development of an embryo. (09 Oct 1997) |
| sperm agglutination | Agglutination of spermatozoa. (05 Mar 2000) Previous: Spens, Thomas, spent, speract, sperling, sperm, spermaceti, spermacytic seminomaNext: sperm agglutination, spermalist, spermaphore, spermary, sperm-astersperm agglutination Agglutination of spermatozoa by antibodies or autoantibodies. (12 Dec 1998) |
| sperm-aster | Cytocentrum with astral rays in the cytoplasm of an inseminated ovum; it is brought in by the penetrating spermatozoon and evolves into the mitotic spindle of the first cleavage division. Origin: sperm + G. Aster, a star (aster) (05 Mar 2000) |
| sperm bank | A facility where sperm are kept frozen in liquid nitrogen for later use in artificial insemination. (09 Oct 1997) |
| sperm banking | <procedure> The freezing of sperm for future use. This procedure can allow men to father children after loss of fertility, as in the case following chemotherapy for cancer. (12 May 1997) |
| sperm banks | Centres for acquiring and storing semen. (12 Dec 1998) |
| sperm capacitation | The process by which a spermatozoon becomes capable of fertilizing an ovum after it reaches the ampullary portion of the uterine tube. (12 Dec 1998) |
| sperm cell | Mature sperm cell (male gamete). (18 Nov 1997) |
| sperm count | The number of sperm in the ejaculate (when given as the number of sperm per millileter it is more accurately known as the sperm concentration or sperm density). (09 Oct 1997) |
| sperm crystal | A crystal of spermin phosphate found in the semen; possibly identical to Bottcher's crystal's. (05 Mar 2000) |
| sperm head | The anterior, usually ovoid, nucleus-containing part of spermatozoa. (12 Dec 1998) |
| sperm immobilizing agents | Chemical substances with sperm immobilizing activity used as topically administered vaginal contraceptives. (12 Dec 1998) |
