Collection and freezing of equine epididymal spermatozoa
The first report of a foal born after artificial insemination (AI) with frozen/thawed semen, more than fifty years ago, was the result of insemination with epididymal spermatozoa (Barker en Gandier, 1957). Ever since, reports have confirmed pregnancies and/ or births after AI with epididymal semen, which proves the fertilizing capacity of epididymal semen (Morris, 2002; Monteiro et al., 2011). ...
متن کاملEffects of storage duration at 5 ºC and type of cryoprotectant on cooled and frozen-thawed ram epididymal spermatozoa
Freezing of ejaculated and epididymal spermatozoa is currently a subject of interest with the purpose of establishing an efficient gene banking model for valuable animals or endangered species. Therefore, the present study evaluated the influence of different storage duration )0, 1.5 and 5 h) at 5 ºC and type of cryoprotectant on freezability of ram epididymal spermatozoa. With increasing the s...
متن کاملImmunogenicity of Testicular and Epididymal Spermatozoa
Problem: The sequential changes in the immunogenicity of spermatozoa in male reproductive tract and the effect of seminal vesicle secretions are long thought to act as central players in influencing immunological equilibrium in the male reproductive tract. Method of Study: Popliteal lymph nodes of mice were collected on the 8th day after sensitizing them with the testicular and epididymal sperm...
متن کاملRefrigerated storage of red deer epididymal spermatozoa in the epididymis, diluted and with vitamin C supplementation.
We have approached the problem of refrigerated storage of epididymal sperm samples from red deer by comparing three options: storing the genital (testicles within the scrotum), diluting the semen in extender or diluting the semen in extender supplemented with an anti-oxidant. Twenty-nine pairs of testes were collected. Spermatozoa from one of each of the pairs were immediately recovered, and di...
متن کاملDetrimental Effects of Non-Functional Spermatozoa on the Freezability of Functional Spermatozoa from Boar Ejaculate
In the present study, the impact of non-functional spermatozoa on the cryopreservation success of functional boar spermatozoa was evaluated. Fifteen sperm-rich ejaculate fractions collected from five fertile boars were frozen with different proportions of induced non-functional sperm (0--native semen sample-, 25, 50 and 75% non-functional spermatozoa). After thawing, the recovery of motile and ...
