The role of the molecular chaperone heat shock protein A2 (HSPA2) in regulating human sperm-egg recognition

open access: yesAsian Journal of Andrology, 2015
One of the most common lesions present in the spermatozoa of human infertility patients is an idiopathic failure of sperm-egg recognition. Although this unique cellular interaction can now be readily by-passed by assisted reproductive strategies such as ...

Cytofluorometric analysis of spermatocytic seminoma [PDF]

open access: yesCancer, 1993
Whether spermatocytic seminoma (SS) develops during meiosis or not is still controversial. To determine that, the DNA content of large, small, and intermediate cells of SS was measured by cytofluorometry to obtain DNA histograms for each cell type. The large cells were aneuploid and showed cell cycles with G0/G1 DNA values from 3C to 18C. The ploidy of

Hormonal control and signaling of the testis of the bat Molossus molossus during the processes of testicular maturation, regression, and recrudescence

open access: yesThe Anatomical Record, EarlyView.
Abstract Molossus molossus, a species of neotropical bat belonging to the Molossidae family, has an annual reproductive cycle that includes two peaks of spermatogenic activity, one in April and another in September, and a period of total testicular regression in December.

Disappearance of UNO-EGFP during M I in Cap-D3EY00456/ Df spermatocyte.

open access: yes, 2021
Cap-D3EY00456/ Df spermatocytes expressing UNO-EGFP, Cenp-A/Cid-EGFP and His2Av-mRFP were analyzed by time-lapse imaging at 45 sec intervals. Progression through M I, as observed in the spermatocyte presented in Fig 5B, is shown in a maximum intensity ...

A comparative evaluation of semen parameters in pre- and post-Hurricane Katrina human population

open access: yesAsian Journal of Andrology, 2015
A natural disaster leading to accumulation of environmental contaminants may have substantial effects on the male reproductive system. Our aim was to compare and assess semen parameters in a normospermic population residing in the Southern Louisiana, USA

Ursolic Acid Alleviates Orchitis via Modulating Ferroptosis in Peritubular Myoid Cells of Testis

open access: yesAnimal Research and One Health, EarlyView.
Ursolic acid modulates key ferroptosis‐related pathways in the peritubular myoid cells of the testis in forest musk deer. ABSTRACT Chronic stress adversely affects reproductive health, increasing susceptibility to pathologies such as orchitis. Additionally, the maintenance of iron homeostasis is essential for preserving the function of the testicles ...

PUF-8 and MPK-1: Genetic and Chemical Control of Spermatocyte Dedifferentiation in Caenorhabditis elegans

open access: yes, 2023
Stem cells face a number of major fate decision during their development: the decision to self-renew or differentiate, and then whether to remain differentiated or dedifferentiate, as occurs in some oncogenesis.

Varicocele and testicular function

open access: yesAsian Journal of Andrology, 2015
Testicular varicocele, a dilation of the veins of the pampiniform plexus thought to increase testicular temperature via venous congestion, is commonly associated with male infertility.

Functional Analysis of Hydrolethalus Syndrome Protein HYLS1 in Ciliogenesis and Spermatogenesis in Drosophila

open access: yesFrontiers in Cell and Developmental Biology, 2020
Cilia and flagella are conserved subcellular organelles, which arise from centrioles and play critical roles in development and reproduction of eukaryotes. Dysfunction of cilia leads to life-threatening ciliopathies.
