Varicocelectomy May Improve Results for Sperm Retrieval and Pregnancy Rate in Non-Obstructive Azoospermic Men
Objective Improvement in sperm density and motility after varicocelectomy have been widely reported for men with oligoasthenoteratospermia (OAT),However the value of varicocelectomy in azoospermic men remain controversial.In this study we have evaluated the outcome of microsurgical varicocelectomy in nonobstructive azoospermic (NOA) men with clinical varicocele in five years in royan institute....

متن کاملAssociation between JMJD1A Expression and Sperm Retrieval in Non-Obstructive Azoospermic Patients
Identification of molecular markers which can predict the outcome of sperm retrieval non-invasively in patients with non-obstructive azoospermia (NOA) are valuable in clinical andrology. Jumonji domain-containing 1a (JMJD1A) is a significant epigenetic regulator during spermatogenesis, which plays an important role in the differentiation of post-meiotic germ cells into mature spermatozoa. We th...
متن کاملOocyte cryopreservation.
OBJECTIVE To review historical and contemporary advances in oocyte-cryopreservation techniques and outcomes. DESIGN Publications related to oocyte cryopreservation were identified through MEDLINE and other bibliographic databases. CONCLUSION(S) Oocyte cryopreservation can be used as an adjunct to conventional IVF and as an option for fertile women to electively cryopreserve their gametes. R...
