| sex hormone | <endocrinology> Hormone that is secreted by gonads or that influences gonadal development. Examples are oestrogen, testosterone, gonadotrophins. (18 Nov 1997) |
|---|---|
| sex hormone-binding globulin | A glycoprotein migrating as a beta-globulin. Its molecular weight, 52,000 or 95,000-115,000, indicates that it exists as a dimer. The protein binds testosterone, dihydrotestosterone, and estradiol in the plasma. Changes in its concentration significantly affect the ratio of unbound (biologically active) testosterone to estradiol in plasma. (12 Dec 1998) |
| sex hormones | Hormones having oestrogenic (female sex hormones) or androgenic (male sex hormones) activity. (12 Dec 1998) |
| sex-influenced | Denoting a class of genetic disorders in which the same genotype has differing manifestations in the two sexes; the variation may be rational (e.g., breast cancer occurs less frequently in males) or have only empirical support (e.g., pattern baldness behaves as a dominant trait in the male and as a recessive trait in the female). See: sex-influenced inheritance. (05 Mar 2000) |
| sex-influenced esterase | <enzyme> Sex hormone-dependent enzyme; liver enzyme may be a precursor of sex-influenced esterase Registry number: EC 3.1.1.- Synonym: es-si esterase, liver sex-influenced esterase (26 Jun 1999) |
| sex-influenced inheritance | Inheritance that is autosomal but has a different intensity of xpression in the two sexes, e.g., male pattern baldness. (05 Mar 2000) |
| sex-limited | Occurring in one sex only. See: sex-limited inheritance. (05 Mar 2000) |
| sex-limited inheritance | Inheritance of a trait that can be expressed in one sex only, e.g., testicular feminization. (05 Mar 2000) |
| sex-linked | <genetics> A genetic disorder where the genetic defect is linked to one of the chromosomes that determines sex (x or y). This is usually due to a gene on the unpaired portion of the X chromosome. Recessive X linked alleles are fully expressed in the heterogametic sex because they can have only one copy of the gene. Thus X linked mutant disorders are more common in human males than in females. An example is haemophilia, which is autosomal recessive and linked to the X chromosome, so only males (XY) actually manifest the disease. (06 Oct 1997) |
| sex-linked character | An inherited character determined by a gene on a gonosome. See: gene. (05 Mar 2000) |
| sex-linked inheritance | The pattern of inheritance that may result from a mutant gene located on either the X or Y chromosome. (05 Mar 2000) |
| sex-linked locus | Any locus that in normal karyotypes is borne on a heterosome; commonly but incorrectly applied to an X-linked locus. (05 Mar 2000) |
| sex manuals | Books used for sex education and procedural instruction. (12 Dec 1998) |
| sex maturation | Achievement of full sexual capacity. Applies to animals and humans. (12 Dec 1998) |
| sex offenses | Any violation of established legal or moral codes in respect to sexual behaviour. (12 Dec 1998) |
