Pharmacogenetics of follicle‐stimulating hormone action in the male

open access: yesAndrology, EarlyView.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

White guava (Psidium guajava L.) fruit juice ameliorated the number of spermatogenic cells in rats (Rattus Novergicus) exposed to lead acetate

open access: yesOvozoa: Journal of Animal Reproduction
This study aims to determine the effect of oral administration of white guava fruit juice (Psidium guajava L.) on the spermatogenic cells of rats (Rattus norvegicus) exposed orally to lead acetate.

MOF influences meiotic expansion of H2AX phosphorylation and spermatogenesis in mice.

open access: yesPLoS Genetics, 2018
Three waves of H2AX phosphorylation (γH2AX) have been observed in male meiotic prophase I: the first is ATM-dependent and occurs at leptonema, while the second and third are ATR-dependent, occuring at zygonema and pachynema, respectively.

The role of iron in normal and impaired testicular function

open access: yesAndrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Presence and localization of a 30-kDa basic fibroblast growth factor-like protein in rodent testes [PDF]

open access: yes, 1991
We have used a recently characterized rabbit antiserum against basic fibroblast growth factor (bFGF), which recognizes various forms of bFGF, to examine the presence and localization of bFGF in the testes of adult rats and mice and the 5-day-old rat.

Cryptorchidism: Novel genetic insights into CCDC149 mutations

open access: yesAndrology, EarlyView.
Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

open access: yesAndrology, EarlyView.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

Developmental regulation of expression of the lactate dehydrogenase (LDH) multigene family during mouse spermatogenesis [PDF]

open access: yes, 1990
Expression of the Lactate Dehydrogenase (LDH) genes during various stages of spermatogenesis was studied by using a combination of Northern blot analyses and in situ hybridization techniques.
