High-magnification ICSI overcomes paternal effect resistant to conventional ICSI

Reproductive BioMedicine Online, 2006
Previous studies have shown that repeated intracytoplasmic sperm injection (ICSI) failures can be caused by a paternal effect. Other studies have suggested that ICSI results are compromised if morphologically abnormal spermatozoa are injected into oocytes.

Integrated Reproductive and Cytogenetic Assessment of Infertility in a Captive Jaguar (Panthera onca)

Veterinary Medicine and Science, Volume 12, Issue 6, November 2026.
Integrated reproductive and cytogenetic assessment of infertility in a captive jaguar pair identified normal chromosomal status in both individuals, whereas impaired semen quality in the male likely represents a major limiting factor for reproductive success under the observed conditions.

Microbial and Metabolic Correlates of Endometrial Dysfunction in Polycystic Ovary Syndrome: A Translational Study

BJOG: An International Journal of Obstetrics &Gynaecology, Volume 133, Issue 12, Page 2092-2102, November 2026.
ABSTRACT Objective Women with polycystic ovary syndrome (PCOS) exhibit a substantially increased risk of miscarriage, yet the underlying mechanisms remain inadequately understood. This study aimed to investigate whether specific gut microbial dysbiosis and metabolic disturbance are associated with and may potentially contribute to endometrial ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, Volume 14, Issue 8, Page 2388-2400, November 2026.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

Biallelic Truncating Variant in LRGUK Is Associated With Severe Multiple Morphological Abnormalities of the Sperm Flagella and Sperm Nuclear Defects in Humans

Clinical Genetics, Volume 110, Issue 5, Page 538-548, November 2026.
A homozygous truncating variant in LRGUK results in loss of the LRGUK protein and causes multiple morphological abnormalities of the flagella (MMAF), disrupted axonemal architecture, central pair defects, abnormal chromatin organization, and severe male infertility, establishing LRGUK as a novel human infertility gene.

Scriptaid is a prospective agent for improving human asthenozoospermic sample quality and fertilization rate in vitro

Asian Journal of Andrology
Male infertility is a global issue caused by poor sperm quality, particularly motility. Enhancement of the sperm quality may improve the fertilization rate in assisted reproductive technology (ART) treatment.
