Outcomes of microdissection testicular sperm extraction in men with nonobstructive azoospermia due to maturation arrest
Tuesday, September 1, 2015The sperm retrieval rate using microdissection testicular sperm extraction in men with maturation arrest is 52%; men with late maturation arrest and higher follicle-stimulating hormone levels have the highest rates.
Is ex vivo microdissection testicular sperm extraction indicated for infertile men undergoing radical orchiectomy for testicular cancer Case report and literature review
Monday, March 31, 2014Areas of spermatogenesis may be missed with conventional testicular sperm extraction (TESE) in azoospermic men with testicular cancer. Microdissection TESE should be offered at orchiectomy to maximize sperm retrieval.
Using contemporary microdissection testicular sperm extraction techniques older men with nonobstructive azoospermia should not be deterred from becoming fathers
Thursday, February 20, 2014Reflections on "Age does not adversely affect sperm retrieval in men undergoing microdissection testicular sperm extraction," by Ramasamy et al.
Impact of fresh versus cryopreserved testicular sperm upon intracytoplasmic sperm injection pregnancy outcomes in men with azoospermia due to spermatogenic dysfunction a meta analysis
Friday, January 31, 2014After review and meta-analysis of the use of fresh versus cryopreserved sperm for intracytoplasmic sperm injection in azoospermic men with spermatogenic dysfunction, we found no difference in pregnancy or fertilization rates.
Controversy over the use of fresh versus frozen thawed sperm for in vitro fertilization intracytoplasmic sperm injection
Friday, January 31, 2014Reflections on "Impact of fresh versus cryopreserved testicular sperm upon intracytoplasmic sperm injection pregnancy outcomes in men with azoospermia due to spermatogenic dysfunction: a meta-analysis" by Ohlander et al.
Genetic variants in the ETV5 gene in fertile and infertile men with nonobstructive azoospermia associated with Sertoli cell-only syndrome
Thursday, September 27, 2012We showed that the homozygous +48845 G>T (TT allele) variant in the ETV5 gene is associated with Sertoli cell–only (SCO) syndrome and nonobstructive azoospermia (NOA) in Australian men.
Studying nonobstructive azoospermia in cystinosis: histologic examination of testes and epididymis and sperm analysis in a Ctns−/− mouse model
Thursday, June 28, 2012Male cystinosis patients are infertile. Male Ctns-/- mice (cystinosis mouse model) showed normal fertility compared with wild-type mice (measured by litter size). Also, histology of testes and epididymis as well as sperm analysis were similar in both groups.
