In this study, the authors investigated the genetic cause of spermatogenetic failure in a consanguineous Turkish family with four infertile and three fertile brothers by using whole exome sequencing (WES).
Six H-E stained testis sections for each rat were evaluated by two histologists in a blind manner for histopathological alterations in interstitial spaces (edema, vascular congestion, inflammation, and Leydig cell damage) and STs (tubular basal membrane damage, spermatogenetic and Sertoli cell damages, MNGC presence, and tubular lumen changes).
The decrease in CDC25A mRNA expression indicates an interruption in the spermatogenetic process.
In contrast, GSI values of testes showed that the mature stages are covered in the season of summer with increase in temperature and also raise the spermatogenetic activity whereas, the primary and secondary spermatocytes and spermatids were filled in the lumen of lobules.
Tdrd5 deficiency in mice leads to spermatogenetic arrest at the round spermatid stage through unregulated retrotransposon silencing (Yabuta et al., 2011).
Spermatogenetic failure, including azoospermia and oligospermia, is one of the important causes of male infertility [113].
The exclusion criteria were the following: abnormalities of the uterine cavity, the presence of an uncontrolled thyroid disease, surgically diagnosed endometrioses, submucosal myoma, ovarian cysts discovered on transvaginal ultrasound and the existence of severe spermatogenetic disturbances in the patients' partners that required ICSI technique.
Loss of Sohlh1, undifferentiated spermatogonia failed in differentiating to spermatocytes.Sohlh1 directly stimulates Kit transcription in postnatal spermatogonia, thus activates the signalling involved in spermatogonia differentiation and spermatogenetic progression(Barrios et al., 2012).
Progestin is an essential factor for the initiation of the meiosis in spermatogenetic cells of the eel.
