Azoospermia: a Genomic Review [PDF]
, 2017 Azoospermia or the absence of sperm in semen is one of the sperm disorders that results in male infertility. There are two types of azoospermia, the first one isazoospermia caused by obstruction of the vas deferens (obstructive azoospermia) and the ...

Frontiers in Endocrinology, 2023 Background Many circular RNAs (circRNAs) are specifically expressed in the testes and seminal plasma of patients with non-obstructive azoospermia (NOA), highlighting them as potential predictors of microdissection testicular sperm extraction (micro-TESE)

The use of deidentified organ donor testes for research
Andrology, EarlyView.Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...

Distribution and number of Cajal-like cells in testis tissue with azoospermia
Kaohsiung Journal of Medical Sciences, 2017 We investigated the number and distribution of Cajal-like cells in patients with azoospermia. A total of 99 patients with non-obstructive azoospermia were divided into subgroups [19 patientsin hypospermatogenesis group (S1), 40 patients in maturation ...

Ooplasmic injections of secondary spermatocytes for non-obstructive azoospermia
The Lancet, 1998 THE LANCET • Vol 351 • April 18, 1998 1177 difference in frequency of IOL, instrumental vaginal delivery, or Caesarean section between the groups. There was a trend towards a greater number of elective Caesareans among doctors (6/10 of the doctors elective Caesareans were by maternal request compared to 2/7 of the matched controls). Although the number

Whole Exome Sequencing Identifies Genes Associated With Non-Obstructive Azoospermia
Frontiers in Genetics, 2022 Background: Non-obstructive azoospermia (NOA) affects nearly 1% of men; however, the landscape of the causative genes is largely unknown. Objective: To explore the genetic etiology which is the fundamental cause of NOA, a prospective ...

Andrology, EarlyView.Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

STAG3 is a strong candidate gene for male infertility [PDF]
, 2014 Oligo- and azoospermia are severe forms of male infertility. However, known genetic factors account only for a small fraction of the cases. Recently, whole-exome sequencing in a large consanguineous family with inherited premature ovarian failure (POF ...
