Comprehensive investigation in patients affected by globozoospermia [PDF]

open access: yesAndrology, 2015
SummaryThe aim of this study was to provide a comprehensive genetic/phenotypic characterization of subjects suffering infertility owing to sperm macrocephaly (n = 3) or globozoospermia (n = 9) and to investigate whether the patients’ genetic status was correlated with the alteration of various sperm parameters.

Oxidative Stress-Related Programmed Cell Death in Male Infertility: Focussing on Ferroptosis. [PDF]

open access: yesJ Cell Mol Med
ABSTRACT Oxidative stress is a common occurrence in testicular cells of infertile men and is considered a significant cause of male reproductive dysfunction. The increase in reactive oxygen species (ROS) leads to impaired spermatogenesis by activating caspases and generating free radicals from mitochondria, resulting in DNA damage and cell death ...

Advancing ASMS with LC‐MS/MS for the discovery of novel PDCL2 ligands from DNA‐encoded chemical library selections

open access: yesAndrology, Volume 11, Issue 5, Page 808-815, July 2023., 2023
Abstract Background A safe, effective, and reversible nonhormonal male contraceptive drug is greatly needed for male contraception as well as for circumventing the side effects of female hormonal contraceptives. Phosducin‐like 2 (PDCL2) is a testis‐specific phosphoprotein in mice and humans.

Loss of Profilin3 Impairs Spermiogenesis by Affecting Acrosome Biogenesis, Autophagy, Manchette Development and Mitochondrial Organization

open access: yesFrontiers in Cell and Developmental Biology, 2021
Profilins (PFNs) are key regulatory proteins for the actin polymerization in cells and are encoded in mouse and humans by four Pfn genes. PFNs are involved in cell mobility, cell growth, neurogenesis, and metastasis of tumor cells.

Compound Heterozygous Mutations in FSIP2 Cause Morphological Abnormalities in Sperm Flagella Leading to Male Infertility

open access: yesAndrologia, Volume 2023, Issue 1, 2023., 2023
Multiple morphological abnormalities of sperm flagella (MMAF) indicate severe teratozoospermia. The fibrous sheath interacting protein 2 (FSIP2) plays an important role in the normal construction of the flagella. In this study, a novel compound heterozygous mutation site of FSIP2, involving c.272_275delinsAGGTTTTTATA (p.L92Vfster74) and c ...

Influence of ejaculatory abstinence period on semen quality of 5165 normozoospermic and oligozoospermic Nigerian men: A retrospective study

open access: yesHealth Science Reports, Volume 5, Issue 5, September 2022., 2022
Abstract Background and Aims Several studies have shown that the length of ejaculatory abstinence alters sperm quality. However, the available data are conflicting and none seems to exist in a Nigerian population. The present study aims to compare the semen quality in normozoospermic and oligozoospermic semen samples of a homogenous Nigerian population,

Intracytoplasmic sperm injection with assisted oocyte activation resulting in successful pregnancies and live birth in couples with globozoospermia: A report of two cases

open access: yesJournal of Human Reproductive Sciences, 2018
Globozoospermia, characterized by round-headed acrosomeless sperm, is a rare and severe form of teratozoospermia. We report a successful pregnancy in two cases of total globozoospermia after intracytoplasmic sperm injection (ICSI) with oocyte activation ...

A recurrent ZP1 variant is responsible for oocyte maturation defect with degenerated oocytes in infertile females

open access: yesClinical Genetics, Volume 102, Issue 1, Page 22-29, July 2022., 2022
Several genes are responsible for ovulatory disorders, especially for oocyte maturation defect with TUBB8 related to oocyte meiotic arrest, PATL2 associated to the retrieval of oocytes blocked at the germinal vesicle stage and ZP1 for which patients present no oocytes or atretic oocytes.
