| 설명 | 1. 신체적 혹은 정신적으로 폭넓은 개념에서의 발달과정의 최종단계를 의미한다. 발달은 모든 사람에게 공통적인 현상이지만 그 발달속도에는 개인에 따라 차이가 있다. 2. 생물이 각각 종으로서의 특징을 충분히 발휘할 수 있게 되는 것. 식물의 성숙은 꽃이 피고 열매를 맺을 수 있는 상태가 되는 것을 말하고, 동물의 경우도 생식능력을 가진 상태로 여러 가지 형질이 완성되는 것을 말한다. 사람의 성숙은 정신적-육체적으로는 완전한 성숙을 이루지 않았는데도 성적으로 성숙하는 수가 있다. 이른바 사춘기가 되면 남자는 15~16세에 목소리가 변하기 시작하고 수염도 진하게 되며, 고환은 정자를 만들게 된다. 여자는 이 무렵이 되면 피하지방이 많아지고 몸매도 갖추어지며 유방도 커지고, 난소 내에는 많은 난자가 축적되어 한달에 한번씩 배란을 하게 된다. 사람의 육체적인 성숙은 남자는 24~25세, 여자는 이보다 조금 빠르다. |

| 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)  |

| sperm maturation | Posttesticular ripening of spermatozoa. (12 Dec 1998) |

| maturation | 1. Achievement of full development or growth. 2. Developmental changes that lead to maturity. 3. Processing of a macromolecule; e.g., posttranscriptional modification of RNA or posttranslational modification of proteins. Origin: L. Maturatio, a ripening, fr. Maturus, ripe (05 Mar 2000) |

| maturation arrest | Cessation of complete differentiation of cells at an immature stage; in spermatogenic maturation arrest, the seminiferous tubules contain spermatocytes, but no spermatozoa develop. (05 Mar 2000) |
| maturation factor | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 1997) |
| maturation index | An index indicating the degree of maturation attained by the vaginal epithelium as adjudged by the cell types being exfoliated; serves as an objective means of evaluating hormonal secretion or response; represents the percentage of parabasal cells/intermediate cells/superficials, in that order; "shift to the left" indicates more immature cells on the surface (atrophy), while "shift to the right" indicates more mature epithelium. (05 Mar 2000) |
| maturation-promoting factor | <enzyme> A protein kinase that drives both the mitotic and meiotic cycles in all eukaryotic organisms. In meiosis it induces immature oocytes to undergo meiotic maturation. In mitosis it has a role in the G2/M phase transition. Once activated by cyclins, maturation-promoting factor directly phosphorylates some of the proteins involved in nuclear envelope breakdown, chromosome condensation, spindle assembly, and the degradation of cyclins. The catalytic subunit of maturation-promoting factor is protein p34cdc2. Acronym: MPF (12 Dec 1998) |
| maturation value | An indicator of the level of maturation attained by vaginal epithelium and used as a factor in cytohormonal evaluation from the maturation index by valuing the parabasal cells at 0.0, the intermediate cells at 0.5, and the superficial cells at 1.0; for special investigations, subtypes of a major cell can be given different values's. (05 Mar 2000) |
| sex maturation | Achievement of full sexual capacity. Applies to animals and humans. (12 Dec 1998) |
| erythrocyte maturation factor | <biochemistry> Member of the water soluble B vitamin group, important in the proper function of the nervous system and important in proper carbohydrate, protein and fat metabolism. (27 Sep 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) |
