Spermatogonia: stem cells with a great perspective [PDF]

open access: yesReproduction, 2001
Interest in spermatogonia has grown in recent years as a result of exciting developments in stem cell research in general and the development of new research tools allowing the isolation, culture and transplantation of these cells. This review focuses on the methodological breakthroughs and highlights the recent findings that have substantially ...

Identification of fish spermatogenic cells through high-throughput immunofluorescence against testis with an antibody set

open access: yesFrontiers in Endocrinology, 2023
Image-based identification and quantification of different types of spermatogenic cells is of great importance, not only for reproductive studies but also for genetic breeding.

Methylation of the Gpat2 promoter regulates transient expression during mouse spermatogenesis [PDF]

open access: yes, 2015
Spermatogenesis is a highly regulated process that involves both mitotic and meiotic divisions, as well as cellular differentiation to yield mature spermatozoa from undifferentiated germinal stem cells.

Organotypic Rat Testicular Organoids for the Study of Testicular Maturation and Toxicology

open access: yesFrontiers in Endocrinology, 2022
An in vitro system to study testicular maturation in rats, an important model organism for reproductive toxicity, could serve as a platform for high-throughput drug and toxicity screening in a tissue specific context. In vitro maturation of somatic cells

Zika virus infection in semen: Effect on human reproduction [PDF]

open access: yes, 2017
Unique among vector-borne flaviviruses, Zika virus can infect testis and male genital tract, can persist in semen for months after symptoms onset, and be sexually transmitted.

BRCA1 preserves genome integrity during the formation of undifferentiated spermatogonia

open access: yesEMBO Reports

New perspectives on fertility in transwomen with regard to spermatogonial stem cells

open access: yesReproduction and Fertility, 2023
Objective: Germ cells of transwomen are affected by gender-affirming hormone therapy (GAHT). Fertility will be lost after surgical intervention; thereby, fertility preservation becomes an increasingly imortant topic.

Doxorubicin Affects Testicular Lipids with Long-Chain (C18-C22) and Very Long-Chain (C24-C32) Polyunsaturated Fatty Acids [PDF]

open access: yes, 2007
Doxorubicin disrupts spermatogenesis by causing apoptosis of spermatogonia and primary spermatocytes. The aim of this study was to examine the effect of this agent on adult rat testicular lipids and their fatty acids.

Comparative Single‐Cell Transcriptomic Atlas Reveals the Genetic Regulation of Reproductive Traits

open access: yesAdvanced Science, EarlyView.
A cross‐species single‐cell transcriptomic atlas of reproductive and central nervous system tissues from sheep and humans reveals conserved cellular programs and regulatory networks that regulated fertility. Integration with GWAS for sheep lifetime average litter size identifies UNC5–SLIT–BMP signaling as a core pathway coordinating neuroendocrine ...

Fraksi Heksan Ekstrak Biji Pepaya Muda Dapat Menghambat Proses Spermatogenesis Mencit Jantan Lebih Besar Daripada Fraksi Metanol Ekstrak Biji Papaya Muda [PDF]

open access: yes, 2008
Fraksi ekstrak heksan mengandung dua golongan zat aktif yang bersifat antifertilitas yaitu golongan steroid dan golongan triterpenoid yang diperkirakan bersifat antifertilitas, walupun mekanisme kerjanya belum jelas.
