Development, Live Birth and Fertility in Mouse Oocytes Penetrated by Spermatids Exposed to the HDAC Inhibitor Scriptaid

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose In mouse embryos derived from round spermatid injection (ROSI), low developmental potential due to abnormal histone modification is improved by histone deacetylase (HDAC) inhibitors. However, some studies suggest that the use of such inhibitors leads to the birth of hypomorphic offspring.

A Comparative Analysis of Intratesticular Versus Intra‐Epididymal Injections of Clove Essential Oil on Male Dog Sterilization

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
This study evaluated clove essential oil as a non‐surgical sterilant in male dogs. Both intratesticular and intra‐epididymal injections significantly reduced sperm concentration, motility and viability, with histological and sonographic evidence of reproductive tissue damage.

Impact of age at first visit on glycolipid metabolism, bone metabolism, and fertility potential in patients with Klinefelter syndrome

Andrology, Volume 14, Issue 1, Page 122-131, January 2026.
Abstract Background Classic Klinefelter syndrome (KS) is characterized by one extra X chromosome (47, XXY), leading to hypergonadotropic hypogonadism and higher risk of alterations in glycolipid homeostasis, cardiovascular diseases, and low bone mineral density. Most frequently, KS is diagnosed in adulthood because of infertility.

The role and implication of platelet‐rich plasma in male factor infertility: A systematic review of human studies

Andrology, Volume 14, Issue 1, Page 284-293, January 2026.
Abstract Background Cryopreservation causes sperm injury and the success of surgical sperm retrieval (SSR) for azoospermic men is just over half depending on the cause of azoospermia. The role of autologous platelet‐rich plasma (PRP) in male factor infertility (MFI) is unclear. Objective To conduct a systematic review of the role of PRP in MFI focusing

Paternal ischemic heart disease and chance of successful pregnancy outcomes

Andrology, Volume 14, Issue 1, Page 132-139, January 2026.
Abstract Background Only approximately 30% of conceptions result in live births. Historically, research has predominantly focused on maternal factors impacting pregnancy success, despite the cause remaining unidentified in most cases. The influence of paternal factors on a couple's likelihood of achieving a successful pregnancy is still not well ...

Intact spermatogenesis in an azoospermic patient with AZFa (sY84 and sY86) microdeletion and a homozygous TG12-5T variant in CFTR

Basic and Clinical Andrology
Background Azoospermia, the most severe form of male infertility, is categorized into two types: non-obstructive azoospermia (NOA) and obstructive azoospermia (OA), which exhibit significant genetic heterogeneity.
