Associations Between Reproductive Disorders and Specific Physical, Mental, Personality, and Social Characteristics: A Narrative Review

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims The present review aims to ascertain whether reproductive disorders are associated with specific physical, mental, personality, and social traits. This information may be used to support or reject the hypothesis on the origin of infecundity, which proposes that women/men with preferred characteristics, including high ...

Y chromosome microdeletions: are they implicated in teratozoospermia? [PDF]

Human Reproduction, 2005
Y chromosome microdeletions are known to impair spermatogenesis. Screenings for these microdeletions are performed mostly in patients with sperm count abnormalities.We have screened the Y chromosome of 80 infertile patients with sperm morphological abnormalities.

Mapping the Non‐Canonical Splicing Variants: Decrypting the Hidden Genetic Architecture of Idiopathic Male Infertility

Advanced Science, Volume 13, Issue 9, 13 February 2026.
This study highlights the significance of non‐canonical splicing variants in male infertility, a factor often overlooked during the analysis of high‐throughput sequencing data. Incorporating the non‐canonical splicing variants prioritization in the genetic analysis pipeline will increase the genetic diagnosis of patients with male infertility ...

Efficacy and Safety of Hirudotherapy for Improving Sperm Quality Parameters in Male Infertility: A Randomized Controlled Trial

Health Science Reports, Volume 9, Issue 2, February 2026.
ABSTRACT Background and Aims Male infertility, often characterized by impaired sperm parameters, remains a significant clinical challenge. This study aimed to evaluate the efficacy and safety of hirudotherapy (medicinal leech therapy) in improving sperm quality parameters in men with idiopathic infertility.

Sperm defects in primary ciliary dyskinesia and related causes of male infertility [PDF]

, 2020
The core axoneme structure of both the motile cilium and sperm tail has the same ultrastructural 9 + 2 microtubular arrangement. Thus, it can be expected that genetic defects in motile cilia also have an effect on sperm tail formation.
