Sperm retrieval techniques for assisted reproduction.
Different surgical methods such as PESA, MESA, TESA, TESE and micro-TESE have been developed to retrieve spermatozoa from either the epididymis or the testis according to the type of azoospermia, i.e., obstructive or non-obstructive. Laboratory techniques are used to remove contaminants, cellular debris, and red blood cells following collection of the epididymal fluid or testicular tissue. Surg...
متن کاملSperm DNA integrity assessment in prediction of assisted reproduction technology outcome.
BACKGROUND The sperm chromatin structure assay (SCSA) has been suggested as a predictor of fertility in vivo as well as in vitro. The available data however, have been based on limited numbers of treatments. We aimed to define the clinical role of SCSA in assisted reproduction. METHODS A total of 998 cycles [387 intrauterine insemination (IUI), 388 IVF and 223 ICSI] from 637 couples were incl...
متن کاملEffect of polyvinylpyrrolidone on sperm function and early embryonic development following intracytoplasmic sperm injection in human assisted reproduction
The objective here was to review the effects of polyvinylpyrrolidone (PVP) upon sperm function and embryonic development in humans. PVP has been used successfully in intracytoplasmic sperm injection (ICSI) to facilitate the handling and immobilization of sperm for both domestic animals and humans. In our previous reports, PVP solution exists locally in embryos injected during the early developm...
متن کاملSperm capacitation: effect of assisted reproductive technology
The past several decades witnessed great advances in the Andrology Sciences in humans. This certainly increased our knowledge in understanding the process of spermatogenesis, capacitation, and fertilization. Much of this work has been acquired from animal experimentation (1, 2, 3). However, the introduction of assisted reproductive technology improved our understanding of the process of fertili...
