Homozygous mutation in the prokineticin-receptor2 gene (Val274Asp) presenting as reversible Kallmann syndrome and persistent oligozoospermia: case report. [PDF]

open access: yes, 2008
Prokineticin 2 (Prok2) or prokineticin-receptor2 (Prok-R2) gene mutations are associated with Kallmann syndrome (KS). We describe a new homozygous mutation of Prok-R2 gene in a man displaying KS with an apparent reversal of hypogonadism.

Perturbation of genomic imprinting in oligozoospermia [PDF]

open access: yesEpigenetics, 2009
The role of epigenetic modifications in oligozoospermia and other disorders of spermatogenesis remains poorly understood. While a variety of environmental, nutritional and genetic abnormalities can cause oligozoospermia, a condition associated with infertility, it is unclear whether chromatin modifications might be also involved in impaired ...

Tissue specific age acceleration patterns in the sperm of oligozoospermic men

open access: yesFrontiers in Reproductive Health, 2022
To determine if disease can modify aging patterns in an affected tissue without altering the aging patterns of other tissues, blood and semen of individuals with oligozoospermia (n = 10) were compared to the blood and semen of individuals with ...

Sperm transcriptome profiling in oligozoospermia [PDF]

open access: yesJournal of Assisted Reproduction and Genetics, 2011
Investigate in what extent sperm transcriptome of infertile men is different from that of fertile individuals.Semen samples were collected for determination of sperm parameters as well as for RNA isolation. Gene expression profile was investigated in spermatozoa of 8 infertile and 3 fertile men by microarray analysis using the Affymetrix Chip HG-U133 ...

Seminal Fluid Metabolomic Markers of Oligozoospermic Infertility in Humans

open access: yesMetabolites, 2020
Infertility affects 12−15% of couples worldwide, and male factors are the cause of nearly half of all cases. Studying seminal fluid composition could lead to additional diagnostic accuracy and a better understanding of the pathophysiology of male ...

The Effect of Recombinant Human Follicle-Stimulating Hormone on Sperm Quality, Chromatin Status and Clinical Outcomes of Infertile Oligozoospermic Men Candidate for Intracytoplasmic Sperm Injection: A Randomized Clinical Trial [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2021
Background: Follicle-stimulating hormone (FSH) plays a crucial role in spermatogenesis; in this study, we assessed the effect of recombinant human FSH (rhFSH) on sperm parameters, chromatin status and clinical outcomes of infertile oligozoospermic men ...
