In the procedure described, demembranated ram sperm models were treated to decondense their nuclei, and the movement of their sperm tails was then reactivated. The duration of movement was sustained for more than 30 min, with a tail-wave frequency of up to 14 Hz. Decondensed sperm models adhered to each other and to the slide; but adherence was prevented by addition of an anti-agglutination fac...

The axolotl has extraordinary regeneration capacity compared to other vertebrates. This remarkable potential been attributed its life-long neoteny, characterized by the exhibition of embryonic characteristics at adult stage. A recent study provided a detailed morphological analysis sperm morphology Ambystoma mexicanum using routine and histological techniques. primary purpose present is describ...

BACKGROUND Antibodies to human sperm are useful diagnostic reagents for detection of changes in sperm protein expression and their relationship with sperm defects and male infertility. The specificity of Hs-16 monoclonal antibody (mAb) and the localization and frequency of the occurrence of Hs-16-recognized protein on human spermatozoa were investigated. METHODS Samples from 30 fertile men wi...

Increasing production of goats takes their reproductive potential and fertility, into consideration. Gastrointestinal obstructive lesions can set up an intestinal ischaemia-reperfusion. Testicular torsion is an established cause of testicular damage and infertility and is a form of ischaemia-reperfusion injury. This study investigates the effect of intestinal ischaemia-reperfusion (IIR) injury ...

AIM To test the hypothesis that season affects the semen quality of swamp buffalo (Bubalus bubalis) bulls used for artificial insemination (AI) under tropical conditions in Thailand, as it does in Bos taurus and Bos indicus. METHODS Clinical and andrological examinations, and monitoring of semen production and quality were carried out on five mature, healthy swamp buffalo AI bulls in Thailand...

Background ISTS defect in which sperm tail is short and fibrous sheath and axoneme are disorganized, is one of the syndromes that cause male infertility. Although a few studies have been done in this regard, its exact etiology in human is unclear yet. Four candidate genes causing ISTS are SPEF2, RABL2B, and A-kinas anchoring proteins genes (AKAP3 and AKAP4). Proteins which coded by SPEF2 and RA...
