Advanced Paternal Age Impacts Common Loci in the Sperm and Placenta DNA Methylomes

Andrology, Volume 14, Issue 2, Page 528-544, February 2026.
ABSTRACT Background Epidemiological studies have reported an association between advanced paternal age at conception and an increased risk of neurodevelopmental disorders in offspring, such as autism spectrum disorder. Evidence suggests that DNA methylation alterations in spermatozoa of older men may be transmitted to the feto‐placental unit and ...

hnRNPU Safeguards Oocyte Development and Female Fertility via Regulation of Alternative Splicing

The FASEB Journal, Volume 40, Issue 2, 31 January 2026.
Heterogeneous nuclear ribonucleoprotein U (hnRNPU) is essential for oocyte development and female fertility. Oocyte‐specific deletion of Hnrnpu leads to follicular arrest, impaired meiotic maturation, mitochondrial dysfunction, and infertility.

De novo methylation in male germ cells of the common marmoset monkey occurs during postnatal development and is maintained in vitro

Epigenetics, 2017
The timing of de novo DNA methylation in male germ cells during human testicular development is yet unsolved. Apart from that, the stability of established imprinting patterns in vitro is controversially discussed.

HAGE, a cancer/testis antigen expressed at the protein level in a variety of cancers [PDF]

, 2010
The search for novel tumour antigens that are either uniquely expressed or over-expressed in a wide variety of tumours is still ongoing. Because of their expression in a broad spectrum of cancers and limited expression in normal tissues, cancer/testis ...

The impact of hydroalcoholic extracts of Peganum harmala and Piper longum on pituitary- gonad axis hormone levels of male NMRI mice

یافته‌های نوین در علوم زیستی, 2017
Several therapeutic effects have been reported for Peganum harmala and Piper longum. These plants contain flavonoids that probably can affect reproductive endocrine system and reduce fertility.

Deletion of Mgat2 in spermatogonia blocks spermatogenesis

Frontiers in Cell and Developmental Biology
Identifying factors required for spermatogenesis is important for understanding mechanisms of male fertility. Inactivation of either the Mgat1 or Man2a2 gene leads to a block in spermatogenesis causing infertility in male mice. MGAT1 GlcNAc-transferase initiates complex N-glycan synthesis and MAN2A2 mannosidase generates the substrate for MGAT2 GlcNAc ...

Ultrastructure of the reproductive system of the black swamp snake (\u3ci\u3eSeminatrix pygaea\u3c/i\u3e). Part III. The sexual segment of the male kidney. [PDF]

, 2002
In mature male snakes and lizards, a distal portion of the nephron is hypertrophied in relation to its appearance in females and immature males. This sexual segment of the male kidney apparently provides seminal fluid that is mixed with sperm and ...
