| seminiferous tubule dysgenesis | A disorder in which the seminiferous tubules exhibit an abnormal cytoarchitecture and extensive hyalinization; the testes are small, and few spermatozoa are formed; the body habitus may be eunuchoid, and gynaecomastia may be present; urinary gonadotropin output is usually high, and the incidence of mental deficiency and illness increased; sex chromatin may be male or female, and androgen secretion ranges from subnormal to normal. It is a constant feature of (and is often used synonymously with) Klinefelter's syndrome. Synonym: germinal aplasia. (05 Mar 2000) |

| convoluted seminiferous tubule | One of two or three twisted curved tubules in each lobule of the testis, in which spermatogenesis occurs. Synonym: tubulus seminifer contortus, tubulus contortus. (05 Mar 2000) |
|---|---|
| seminiferous tubule | <anatomy> In the testicles, the network of tubes where sperm cells are formed. (09 Oct 1997) |
| straight seminiferous tubule | The continuation of the tubulus seminifer contortus which becomes straight just before entering the mediastinum to form the rete testis. Synonym: tubulus renalis rectus, tubulus seminifer rectus, collecting tubule, straight tubule, tubulus rectus, tubulus rectus, vasa recta. (05 Mar 2000) |
| seminiferous | <biology> Seed-bearing; producing seed; pertaining to, or connected with, the formation of semen; as, seminiferous cells or vesicles. Origin: L. Semen, semenis, seed -ferous. Source: Websters Dictionary (01 Mar 1998) |
| seminiferous epithelium | Specialised epithelium lining the seminiferous tubules containing developing and mature spermatozoa and sertoli cells. (12 Dec 1998) |
| seminiferous tubules | The canals through which the testicular spermatozoa are conveyed to the rete testis. (12 Dec 1998) |
| gonadal dysgenesis | <embryology, genetics> A rare genetic disorder in women that is characterised by the absence of an X chromosome. This disorder inhibits normal sexual development and causes infertility. Features include webbing of the neck, short stature, retarded development of secondary sex characteristics, absence of menses, coarctation of the aorta, low hairline, eye abnormalities (drooping eyelids) and skeletal deformities. Treatment include oestrogen supplementation at puberty. Growth hormone replacement may be necessary in some cases. Cardiac surgery may be necessary to correct coarctation of the aorta. Incidence: 1 in 3,000 births. (10 Oct 1997) |
| gonadal dysgenesis, 46,xy | A syndrome characterised by "streak gonads" in a phenotypic female with a 46,xy karyotype. It is due to a mutation which inhibits the function of the y-borne determinant that would normally cause the indifferent embryonic gonad to differentiate into a testis. The streak gonad is incapable of ovulation or oestrogen secretion. The syndrome is sometimes called "pure gonadal dysgenesis," but this designation may also refer to the presence of streak gonads with a 46,xx karyotype. (12 Dec 1998) |
| gonadal dysgenesis, mixed | A syndrome of gonadal dysgenesis in which there is a testis on one side and a "streak gonad" on the other. The phenotype is generally male, but may be female since the individual is a mosaic. Various karyotypes have been identified, including 45,xo/47,xyy; 45,xo/46,xy; and 45,xo/46,xyo. (12 Dec 1998) |
| hybrid dysgenesis | The inability of certain strains of the fruit fly Drosophila melanogaster to interbreed with each other because they produce offspring that are all sterile or offspring which have a high number of harmful mutations. (09 Oct 1997) |
| dysgenesis | Defective development. (18 Nov 1997) |
| iridocorneal mesodermal dysgenesis | Mesodermal dysgenesis of cornea and iris, producing pupillary anomalies, posterior embryotoxon, and secondary glaucoma. Synonym: Rieger's anomaly. (05 Mar 2000) |
| testicular dysgenesis | A congenital derangement of seminiferous tubular structure and function, resulting in male infertility; the defect in spermatogenesis may be incomplete, as in maturational arrest or premature sloughing, or spermatogenesis may be completely absent, as in the Sertoli-cell-only syndrome. (05 Mar 2000) |
| renal tubule | <anatomy> Small structures in the kidney that filter the blood and produce the urine. (12 Dec 1998) |
| mesonephric tubule | An excretory tubule of the mesonephros. Synonym: segmental tubule. (05 Mar 2000) |
