International Journal of Molecular Sciences, 2021 Azoospermia affects 1% of men, and it can be due to: (i) hypothalamic-pituitary dysfunction, (ii) primary quantitative spermatogenic disturbances, (iii) urogenital duct obstruction. Known genetic factors contribute to all these categories, and genetic testing is part of the routine diagnostic workup of azoospermic men.

Spermatogenesis, 2014 Azoospermia is classified as obstructive azoospermia (OA) or non-obstructive azoospermia (NOA), each having very different etiologies and treatments. The etiology, diagnosis, and management of azoospermia were reviewed and relevant literature summarized.

Bilharziasis and Azoospermia [PDF]
Archives of Andrology, 1980 Two patients in their twenties were investigated for a complaint of primary sterility. Semen analysis, showed azoospermia and testicular biopsy showed inhibited spermatogenesis in association with bilharzia ova in the interstitium in both cases. No similar cases were reported previously in the literature.

Panhypopituatarism and Azoospermia [PDF]
Open Journal of Thyroid Research, 2017 Hypopituitarism may involve the loss of one, several or all hormones of the pituitary gland. It is therefore necessary to complete to determine which hormone (s) are defi cient and need to be replaced. Hormone replacement is possible for all hormones pituitary glands except for prolactin and oxytocin.

The epidemiology and etiology of azoospermia
Clinics, 2013 The misconception that infertility is typically associated with the female is commonly faced in the management of infertile men. It is uncommon for a patient to present for an infertility evaluation with an abnormal semen analysis report before an extensive female partner workup has been performed.

Secretory azoospermia or non-obstructive azoospermia?
Folia Histochemica et Cytobiologica, 2010 In the non-obstructive azoospermia versus the secretory azoospermia it is first necessary to have a clear assessment and definition and then takes care of the patient before the surgical sampling taking into account the age of the woman and in fine try to optimize the residual spermatogenesis.

Genetic defects in human azoospermia [PDF]
Basic and Clinical Andrology, 2019 As with many other diseases, genetic testing in human azoospermia was initially restricted to karyotype analyses (leading to diagnostic chromosome rearrangement tests for Klinefelter and other syndromes). With the advent of molecular biology in the 1980s, genetic screening was broadened to analyses of Y chromosome microdeletions and the gene coding for

International Journal of Gynecology &Obstetrics, EarlyView.Abstract Background Hormone pre‐treatment is still used before assisted reproductive technique (ART) in endometriotic women, but evidence supporting this recommendation is conflicting. Objectives To evaluate whether hormone pre‐treatment with gonadotropin‐releasing hormone (GnRH) agonists or progestogens could improve fertility in women with ...

IJU Case Reports, EarlyView.ABSTRACT Introduction Spermatogenic dysfunction is a side effect of valganciclovir, which is commonly used to treat cytomegalovirus infections. Here, we report the case of a reproductive man who underwent kidney transplantation and was diagnosed with azoospermia after valganciclovir treatment for cytomegalovirus infection.
