Sperm storage by males causes changes in sperm phenotype and influences the reproductive fitness of males and their sons [PDF]

, 2017
Recent studies suggest that environmentally induced effects on sperm phenotype can influence offspring phenotype beyond the classic Mendelian inheritance mechanism.

Birth defects associated with paternal firefighting in the National Birth Defects Prevention Study

American Journal of Industrial Medicine, Volume 66, Issue 1, Page 30-40, January 2023., 2023
Abstract Background Few studies have evaluated birth defects among children of firefighters. We investigated associations between birth defects and paternal work as a firefighter compared to work in non‐firefighting and police officer occupations. Methods We analyzed 1997–2011 data from the multi‐site case‐control National Birth Defects Prevention ...

Sperm mobility: mechanisms of fertilizing efficiency, genetic variation and phenotypic relationship with male status in the domestic fowl, Gallus gallus domesticus [PDF]

, 2002
When females are sexually promiscuous, sexual selection continues after insemination through sperm competition and cryptic female choice, and male traits conveying an advantage in competitive fertilization are selected for. Although individual male and

“Seminal testosterone”, rising viewpoint of local spermatogenesis in nonobstructive azoospermia: One center long-term bidirectional cohort study

Frontiers in Endocrinology, 2022
ObjectiveReproductive hormones are a traditional good method to evaluate spermatogenesis but might not accurately represent local spermatogenesis. To find a more accurate method, seminal reproductive hormones were studied.MethodsA bidirectional cohort ...

Sperm design and variation in the New World blackbirds (Icteridae) [PDF]

, 2009
Post-copulatory sexual selection (PCSS) is thought to be one of the evolutionary forces responsible for the rapid and divergent evolution of sperm design. However, whereas in some taxa particular sperm traits are positively associated with PCSS, in other

To unwind the biological knots: The DNA/RNA G‐quadruplex resolvase RHAU (DHX36) in development and disease

Animal Models and Experimental Medicine, Volume 5, Issue 6, Page 542-549, December 2022., 2022
Schematic diagram showing RHAU can bind and unwind the G4 “knots” to modulate embryonic development and post‐natal organ function. Deficiency of RHAU gives rise to embryonic lethality, impaired organogenesis and organ dysfunction. RHAU modulates Nkx2‐5 mRNA and Yap1 mRNA at the post‐transcriptional level and facilitates the transcription of c‐Kit and ...

Sperm Competition, Sperm Numbers and Sperm Quality in Muroid Rodents

PLoS ONE, 2011
Sperm competition favors increases in relative testes mass and production efficiency, and changes in sperm phenotype that result in faster swimming speeds. However, little is known about its effects on traits that contribute to determine the quality of a whole ejaculate (i.e., proportion of motile, viable, morphologically normal and acrosome intact ...
