Limited Utility of a Test‐Yolk Buffer Semen Extender for Preserving Human Semen Parameters for Use in a Diagnostic Setting

open access: yesAndrology, EarlyView.
ABSTRACT Background Identification of a preservation medium that accurately retains semen parameters would be advantageous for men requiring semen analysis by allowing them to produce sperm samples at home rather than on site or even facilitate ‘mail order’ semen analysis.

Assessment of Sperm DNA Fragmentation in Patients with Partial

open access: yesمجله دانشکده پزشکی اصفهان, 2015
Background: Infertility is estimated to affect up to 15% of couples of reproductive age. Globozoospermia is a rare (incidence < 0.1%) but severe disorder in male infertility.

Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

open access: yesAndrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Limited Clinical Impact of Androgen Receptor Repeat Length (CAG and GGC) in Klinefelter Syndrome: A Multivariable Analysis

open access: yesAndrology, EarlyView.
ABSTRACT Background Klinefelter syndrome (KS) is characterized by marked phenotypic heterogeneity that might be influenced by genetic modifiers, including androgen receptor (AR) repeat length (CAGn and GGCn). The clinical relevance of these repeat lengths in patients with KS before testosterone replacement therapy (TRT) remains unclear.

Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

open access: yesAndrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

open access: yesAndrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Effect of chromatin condensation on frozen-thawed sperm DNA integrity in normozoospermic men

open access: yesمجله علمی دانشگاه علوم پزشکی کردستان, 2019
Background and Aim: Sperm cryopreservation is a common technique used for management of male infertility. But this method has detrimental effects on sperm DNA and chromatin quality.

Intrauterine Growth and Male Reproductive Health: A Follow‐up Study From the Danish National Birth Cohort

open access: yesAndrology, EarlyView.
ABSTRACT Background Reduced intrauterine growth might affect male reproductive health later in life, however, existing research remain inconclusive. Objectives To investigate the association between placental weight and birthweight Z‐scores and semen characteristics, testes volume, and reproductive hormone levels in young men.
