| 설명 | 암수의 성을 결정하는 데 중요한 구실을 하는 염색체. 이것에 대하여 보통의 염색체를 보통염색체라고 한다. 암수의 구별이 있는 생물에서는 암수에 따라 다른 형과 수를 나타내는 염색체이며, 보통염색체에 비해 염색성이나 행동에서 차이가 있다. 특히 동물의 성염색체는 그런 경향이 강하다. 휴지기 및 핵분열 전기에 뚜렷한 이상응축을 나타내며 감수분열 때는 다른 염색체보다 먼저 앞서거나 끌려가는 행동을 보여준다. |

| sex chromosomes | The homologous chromosomes that are dissimilar in the heterogametic sex. There are the x chromosome, the y chromosome, and the w, z chromosomes (in animals in which the female is the heterogametic sex (the silkworm moth bombyx mori, for example). In such cases the w chromosome is the female-determining and the male is zz. (12 Dec 1998) |

| sex cords | The gonadal cord's of the embryonic ovary or testis. Synonym: sex cords. (05 Mar 2000) |
| sex cord-stromal tumour | A malignant neoplasm of the ovary or testis. These tumours differentiate toward sex cords (in embryonic gonads) in the form of female (i.e., granulosa and theca) cells, male (i.e., sertoli and leydig) cells, or indifferent elements. In the ovary, sex cord-stromal tumours comprise 5% of all ovarian neoplasms. In the testes, leydig and sertoli cell tumours comprise about 5% of all testicular neoplasms, 10% of which behave in a malignant fashion. (12 Dec 1998) |
| sex counseling | Advice and support given to individuals to help them understand and resolve their sexual adjustment problems. It excludes treatment for psychosexual disorders or psychosexual dysfunction. (12 Dec 1998) |
| sex determination | Determination of the sex of a foetus in utero by identification of foetal chromosomes. (05 Mar 2000) |
| sex determination (analysis) | Validation of the sex of an individual by inspection of the gonads and/or by genetic tests. (12 Dec 1998) |
| sex determination (genetics) | Process in a given organism, by which the sex genotype is fixed. In humans, sex is established at the time of fertilization by the presence or absence of the y chromosome. (12 Dec 1998) |
| sex differentiation | Differentiation of male and female tissues and organs during embryogenesis, but after sex determination (sex determination (genetic)). (12 Dec 1998) |
| sex differentiation disorders | Disorders in the differentiation process of gonadal tissues and organs during embryogenesis. (12 Dec 1998) |
| sex disorders | Disturbances in normal sexual performance. (12 Dec 1998) |
| sex distribution | The number of males and females in a given population. The distribution may refer to how many men or women or what proportion of either in the group. The population is usually patients with a specific disease but the concept is not restricted to humans and is not restricted to medicine. (12 Dec 1998) |
| sex duction | f duction Previous: sex differentiation disorders, sexdigitate, sex disorders, sex distributionNext: sex duction, sexed, sex education, sex factor, sex factors, sex hormonesex duction <molecular biology> The transfer of genes from one bacterium to another by the process of conjugation. May involve one bacterium with an F' plasmid, in which case the process is called f duction. (14 Oct 1997) |
| sex education | Education which increases the knowledge of the functional, structural, and behavioural aspects of human reproduction. (12 Dec 1998) |
| sex factor | The prototype conjugative plasmid associated with conjugation in the K-12 strain of Escherichia coli. Synonym: F agent, F-factor, F genote, F-genote, fertility agent, fertility factor, sex factor. (05 Mar 2000) |
| sex factors | Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from sex characteristics, anatomical or physiological manifestations of sex, and from sex distribution, the number of males and females in given circumstances.
