Normozoospermic men in infertile couples: Potential benefit of early medical diagnostic procedures

Andrology, EarlyView.
Abstract Introduction Infertility, defined as the inability to achieve pregnancy despite regular, unprotected sexual intercourse for 1 year, affects approximately 15% of couples. Male factors contribute to 50% of these cases. The necessity of andrological evaluations for male partners of infertile couples with normozoospermia is currently under ...

Gut‐Derived Exosomes Mediate the Microbiota Dysbiosis‐Induced Spermatogenesis Impairment by Targeting Meioc in Mice

Advanced Science
Diseases like obesity and intestinal inflammation diseases are accompanied by dysbiosis of the gut microbiota (DSGM), which leads to various complications, including systemic metabolic disorders.

BRD9 inhibition as potential treatment option for testicular germ cell tumors

Andrology, EarlyView.
Abstract Background Testicular germ cell tumors (TGCT) are the predominant tumor in younger males. Usually, 5‐year survival rates are quite high, but 15–20% of patients with metastatic non‐seminomas are resistant to standard cisplatin‐based therapy.

The absence of both RIBC1 and RIBC2 induces decreased sperm motility and litter size in male mice

Andrology, EarlyView.
Abstract Background RIBC1 (RIB43A domain with coiled‐coils 1) and RIBC2 (RIB43A domain with coiled‐coils 2) are homolog proteins of RIB43a which is localized to microtubules in the cilia and flagella of unicellular organisms. Cryo‐electron microscopy and artificial intelligence studies showed that RIBC1 and RIBC2 are microtubule inner proteins (MIPs ...

Semen quality in patients with testicular cancer is associated with age and with greatly elevated levels of beta human chorionic gonadotropin

Andrology, EarlyView.
Abstract Background Poor semen quality is a well‐known feature in patients with testicular germ cell tumours (GCTs) at the time of diagnosis but the underlying biological reasons are incompletely understood. Objectives This study aimed to identify GCT‐specific clinical factors that are involved with poor semen quality in GCT patients.

Spermatogenesis in Equisetum

Botanical Gazette, 1912
1. In the early mitoses in the spermatogenous tissue of Equisetum there are no centrosomes, centrospheres, or asters. 2. A minute granule, surrounded by a weakly developed aster, appears in the cytoplasm near the nucleus in each of the cells of the penultimate generation. This granule divides to two, which become the blepharoplasts. 3.
