Leptin Receptor in Ram Epididymal Spermatozoa
This experiment was designed to investigate leptin receptors (Ob-R and Ob-Rb) mRNA in ram epididymal spermatozoa by RT-PCR. Ten testes were obtained from abattoir and epididymal spermatozoa recovery was performed. To purify spermatozoa, motile sperm were isolated by the swim-up procedure. Total RNA was isolated from epididymal spermatozoa and placental cotyledon, as a positive control, and then...
متن کاملCollection 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 کاملPhosphopeptide Analysis of Rodent Epididymal Spermatozoa
Spermatozoa are quite unique amongst cell types. Although produced in the testis, both nuclear gene transcription and translation are switched off once the pre-cursor round cell begins to elongate and differentiate into what is morphologically recognized as a spermatozoon. However, the spermatozoon is very immature, having no ability for motility or egg recognition. Both of these events occur o...
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 کاملEfficacy of intracytoplasmic sperm injection using intentionally cryopreserved epididymal spermatozoa.
Microsurgical epididymal sperm aspiration was a great advance in the therapy of patients with non-reconstructable, obstructive azoospermia, most notably congenital bilateral absence of the vas deferens. Using conventional in-vitro fertilization, pregnancies were rarely achieved because the rate of oocyte fertilization was extremely poor. However, the use of retrieved spermatozoa in conjunction ...
