Spermatogenesis and Cryptorchidism [PDF]
Frontiers in Endocrinology, 2014 Cryptorchidism represents the most common endocrine disease in boys, with infertility more frequently observed in bilateral forms. It is also known that undescended testes, if untreated, lead to an increased risk of testicular tumors, usually seminomas, arising from mutant germ cells.

Transcriptome profiling of developing testes and spermatogenesis in the Mongolian horse
BMC Genetics, 2020 Background Horse testis development and spermatogenesis are complex physiological processes. Methods To study these processes, three immature and three mature testes were collected from the Mongolian horse, and six libraries were established using high ...

Three-Dimensional Analysis of Busulfan-Induced Spermatogenesis Disorder in Mice
Frontiers in Cell and Developmental Biology, 2020 We examined if the distribution of impaired or normal spermatogenesis differs along the length of seminiferous tubules in disorders of spermatogenesis. For this purpose, three-dimensional (3D) reconstruction of seminiferous tubules was performed in mice ...

In vitro mouse spermatogenesis with an organ culture method in chemically defined medium. [PDF]
PLoS ONE, 2018 We previously reported the successful induction and completion of mouse spermatogenesis by culturing neonatal testis tissues. The culture medium consisted of α-minimum essential medium (α-MEM), supplemented with Knockout serum replacement (KSR) or ...

Cells, 2022 Spermatogenesis is a complex and continuous process of germ-cell differentiation. This complex process is regulated by many factors, of which gene regulation in spermatogenic cells plays a decisive role.

Estrogen and Spermatogenesis* [PDF]
Endocrine Reviews, 2001 AbstractAlthough it has been known for many years that estrogen administration has deleterious effects on male fertility, data from transgenic mice deficient in estrogen receptors or aromatase point to an essential physiological role for estrogen in male fertility.

Kinesins in spermatogenesis† [PDF]
Biology of Reproduction, 2017 Kinesins are essential for the proper function of many types of polar cells, including epithelial cells, neurons, and sperm. Spermatogenesis is closely associated with many different kinesins. These kinesins participate in several fundamental processes, including mitotic and meiotic division, essential organelle transport, and the biogenesis of ...

WormBook, 2006 Spermatogenesis creates functional sperm from an initially undifferentiated germ cell. In the nematode Caenorhabditis elegans, both males and hermaphrodites engage in spermatogenesis. The hermaphrodite germ line, like that of the male, initiates spermatogenesis during the L4 larval stage.

The cytoskeleton in spermatogenesis [PDF]
Reproduction, 2019 Abstract As germ cells progress through spermatogenesis, they undergo a dramatic transformation, wherein a single, diploid spermatogonial stem cell ultimately produces thousands of highly specialised, haploid spermatozoa. The cytoskeleton is an integral aspect of all eukaryotic cells.

Spermatogenesis in the Microminipig [PDF]
Toxicologic Pathology, 2016 The microminipig has considerable potential as an animal model to evaluate general toxicity; however, there are few studies on the male reproductive system, particularly regarding spermatogenesis. The objectives of the present study were to clarify the stages of the seminiferous epithelium cycle on the basis of spermiogenesis and to determine the ...
