The Influence of Kebar Grass Infuse to Mice (Mus musculus) Spermatogenesis

Jurnal Sain Veteriner, 2014
This study was aim to examine the effect of grass infusion kebar (Biophytum petersianum) to increase the activity of spermatogenesis in male mice. This research was conducted at the Laboratory of Botany University Discourse Kristen Duta Yogyakarta ...

Mitochondrial fission regulates germ cell differentiation by suppressing ROS-mediated activation of Epidermal Growth Factor Signaling in the Drosophila larval testis. [PDF]

, 2019
Mitochondria are essential organelles that have recently emerged as hubs for several metabolic and signaling pathways in the cell. Mitochondrial morphology is regulated by constant fusion and fission events to maintain a functional mitochondrial network ...

Constitutively active follicle-stimulating hormone receptor enables androgen-independent spermatogenesis

Journal of Clinical Investigation, 2018
Spermatogenesis is regulated by the 2 pituitary gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone (FSH). This process is considered impossible without the absolute requirement of LH-stimulated testicular testosterone (T) production.

Reproductive Traits of Zoo‐Bred and Wild‐Bred Eastern Massasaugas (Sistrurus catenatus) at Species Survival Plan® Conservation Breeding Centres and Other Facilities

Zoo Biology, EarlyView.
Based on 94 Massasauga litters born in human care, mean litter size and number of live young per litter were higher in wild‐bred than in zoo‐bred litters. Wild‐bred litters more often contained live young than did zoo‐bred litters. In zoo‐bred litters, dam mass was positively associated with above‐average reproductive output.

Critical roles of long noncoding RNAs in Drosophila spermatogenesis

Genome Research, 2016
Long noncoding RNAs (lncRNAs), a recently discovered class of cellular RNAs, play important roles in the regulation of many cellular developmental processes.

Rapid detection of mouse spermatogenic defects by testicular cellular composition analysis via enhanced deep learning model

Andrology, EarlyView.
Abstract Background Histological analysis of the testicular sections is paramount in infertility research but tedious and often requires months of training and practice. Objectives Establish an expeditious histopathological analysis of mutant mice testicular sections stained with commonly available hematoxylin and eosin (H&E) via enhanced deep learning

Growth hormone in male infertility

Indian Journal of Endocrinology and Metabolism, 2011
Growth hormone (GH) is expressed in a variety of tissues, including the testes, and has autocrine and paracrine functions as well. This, along with other factors, exerts autocrine and paracrine control over spermatogenesis.

Selenoproteins in mammalian spermatogenesis:role of the nuclear GPx4 [PDF]

, 2011
The selenoprotein Phospholipid Hydroperoxide Glutathione Peroxidase (PHGPx/GPx4) is an enzyme unique among the various GPxs, because it is able to use protein thiols, beside glutathione, The GPx4 gene encodes for three isoforms having different ...

Imatinib decreases germ cell survival and germline stem cell proliferation in rodent testis ex vivo and in vitro

Andrology, EarlyView.
Abstract Background Imatinib and dasatinib are tyrosine kinase inhibitors (TKIs) increasingly used to treat several diseases in both children and adults at fertile age. We have previously shown that imatinib has adverse effects on developing testis, and imatinib‐treated male patients have been reported to have reduced sperm counts.
