Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, EarlyView.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.

Associação entre proteínas do plasma seminal, motilidade e viabilidade espermática em coelhos submetidos a doping genético Association among seminal plasma proteins, sperm motility and sperm viability in rabbits submitted to gene doping

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2013
Neste trabalho foi estudada a correlação entre o perfil proteico do plasma seminal e a motilidade e viabilidade espermática em coelhos submetidos ao tratamento com vetores de expressão contendo o gene da eritropoetina (EPO) e com EPO recombinante humana.

Detection of germ cell neoplasia in situ and testicular cancer risk in men with testicular microlithiasis: Real world results through 10 years

Andrology, EarlyView.
Abstract Background Guidelines recommend biopsies for men <50 years with testicular microlithiasis and cancer risk factors to rule out germ cell neoplasia in situ. Limited data support this practice. Objectives To clarify the significance of testicular microlithiasis by examining pathological findings in men with testicular microlithiasis.

Cryptorchidism: Novel genetic insights into CCDC149 mutations

Andrology, EarlyView.
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...
