Cryopreservation and fertility of ejaculated and epididymal stallion sperm.
The cryopreservation of epididymal sperm is important to preserve genetic material from valuable deceased males. This study evaluated the viability of sperm samples from eight stallions under three conditions: (1) collected using an artificial vagina (EJ-0h), (2) recovered from the epididymal cauda immediately after orchiectomy (EP-0h), and (3) recovered from the epididymal cauda after 24h of s...
متن کاملDioxin-Induced Changes in Epididymal Sperm Count and Spermatogenesis
A single in utero exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on gestation day 15 decreased epididymal sperm count in adult rats and thus was used to establish a tolerable daily intake for TCDD. However, several laboratories have been unable to replicate these findings. Moreover, conflicting reports of TCDD effects on daily sperm production suggest that spermatogenesis may not be as ...
متن کاملSperm Flagellum Volume Determines Freezability in Red Deer Spermatozoa
The factors affecting the inter-individual differences in sperm freezability is a major line of research in spermatology. Poor sperm freezability is mainly characterised by a low sperm velocity, which in turn is associated with low fertility rates in most animal species. Studies concerning the implications of sperm morphometry on freezability are quite limited, and most of them are based on spe...
متن کاملCryopreservation of Rat Sperm
The laboratory rat, Rattus norvegicus, was the first mammalian species domesticated for scientific research, which work dating back to before 1850. From this auspicious beginning, the rat has become the most widely studied experimental animal model for biomedical research (Jacob, 1999). Since the development of the first inbred rat strain by King 1909, over 500 inbred rat strains have been deve...
متن کاملHuman Sperm Cryopreservation
As the demand for assisted reproductive techniques in humans increases, so does the demand for the oocytes and sperm that are essential for these techniques. Human sperm banks play a key role in assisted human reproduction, as a reservoir of sperm from the semen of donors and as an option for genetic preservation for some patients. There are different techniques that can be used to store human ...
