Establishment of a practical sperm penetration test for bovine semen.
OBJECTIVE Several methods for evaluating semen quality have been developed in addition to traditional semen analysis. Most of these methods are very complex and require expensive technical equipment as well as special knowledge to be performed. The aim of this study was to establish an easy and cost-effective sperm penetration test for bovine semen using artificial media. Additionally a standar...
متن کاملMacaque sperm coating protein DEFB126 facilitates sperm penetration of cervical mucus.
BACKGROUND Sperm coating protein beta-defensin 126 (DEFB126) is adsorbed onto the entire surface of macaque sperm in the caudal epididymis and is retained on viable sperm collected from the cervix and the uterine lumen of mated female macaques. We investigated the role of sperm coating protein DEFB126 in cervical mucus penetration (CMP). METHODS Cervical mucus (CM) was collected from peri-ovu...
متن کاملQuantitative sperm mucus penetration: modified formulae for calculating penetration efficiency.
In 1980 Katz et al. derived a formula for the percentage of successful collisions (PSC) as a quantitative measure of sperm-cervical mucus penetration efficiency. The use of PSC waned after its validity was questioned by reports of values >100% and the observation that PSC varied with the cross-sectional area of the mucus column. The aim of the present study was to develop a more accurate measur...
متن کاملContraception Cervical Mucus Sperm Penetration in Women on Oral Contraception or with an Iud in Situ
Penetration of cervical mucus by spermatozoa was observed in cycling and infertile women, in women on sequential or combination oral contraceptive medication, and in women with an IUD in situ. _Sperm penetration of cervical mucus varied from women not using contraceptives and from infertile women, to patients taking sequential conception control pills. In cycling women penetration was low in th...
متن کاملValidation and application of empirical shear wave velocity models based on standard penetration test
Shear wave velocity is a basic engineering tool required to define dynamic properties of soils. In many instances it may be preferable to determine Vs indirectly by common in-situ tests, such as the Standard Penetration Test. Many empirical correlations based on the Standard Penetration Test are broadly classified as regression techniques. However, no rigorous procedure has been published for c...
