Correlation between motility of testicular spermatozoa, testicular histology and the outcome of intracytoplasmic sperm injection.
The objective of the present study was to analyse the influence of motility on the results of intracytoplasmic sperm injection (ICSI) when testicular spermatozoa are used for microinjection and to correlate this with testicular histology. A total of 197 ICSI treatment cycles (167 couples) was analysed retrospectively in which testicular spermatozoa were used, because of complete azoospermia, fo...
متن کاملTesticular and para-testicular tumors in south western Nigeria.
BACKGROUND Tumors of the testis and paratesticular tissues are rare, especially in men of African descent. In recent reviews however, the incidence is rising among the Caucasians and black Americans. We set out to determine the incidence in South-Western Nigeria and to examine the histopathologic variants. METHODS A retrospective study of patients who had histopathologically confirmed testicu...
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 کاملImprovement of motility after culture of testicular spermatozoa: the effects of incubation timing and temperature
BACKGROUND Sperm motility is the reliable parameter that roles in success of intracytoplasmic sperm injection (ICSI), especially in azoospermia. Selection of appropriate culture duration, temperature and media for enhancing the sperm motility is an important issue in assisted reproduction program. The aim was to evaluate the sperm motion characteristics after culturing of testicular sperm extra...
متن کاملLipid composition and metabolism in testicular and ejaculated ram spermatozoa.
1. Spermatozoa collected directly from the testis of the conscious ram contain 25% more phospholipid than ejaculated spermatozoa. The concentration of lecithin, phosphatidylethanolamine and ethanolamine plasmalogen was greater in testicular spermatozoa; little difference was observed in choline plasmalogen. Both types of spermatozoa had significant amounts of cardiolipin and alkyl ether phospho...
