Male obesity: Associated effects on fertility and the outcomes of offspring

Andrology, Volume 13, Issue 1, Page 64-71, January 2025.
Abstract Obesity rates are increasing globally, making it imperative to comprehend the effects of parental obesity on human reproduction. This review aims to highlight the impact of male obesity on reproductive and offspring outcomes. Male obesity has been shown to affect fertility through various mechanisms, including changes in semen quality ...

Clinical outcomes of round spermatid injection vs intracytoplasmic sperm injection: The role of hormonal pretreatment for nonobstructive azoospermia

Journal of the Chinese Medical Association
Background: Round spermatid injection (ROSI) into oocytes offers men with nonobstructive azoospermia (NOA) the opportunity to have biological offspring in cases where mature spermatozoa are not detected. However, the clinical outcomes of ROSI remain poor.

Male factor infertility with Azoospermia: our experience in a tertiary care centre [PDF]

Azoospermia is the absence of spermatozoa in two separate centrifuged semen samples. It is one of the major contributors of male factor infertility. Usually detected in the course of infertility evaluation.

CITED2 Binding to EP300 Regulates Human Spermatogonial Stem Cell Proliferation and Survival Through HSPA6

Stem Cells International, Volume 2025, Issue 1, 2025.
Spermatogonial stem cells (SSCs) are essential for the initiation and continuation of spermatogenesis, a process fundamental to male fertility. Despite extensive studies on mouse SSCs, the mechanisms governing self‐renewal and differentiation in human SSCs remain to be elucidated.

HSF5 Deficiency Causes Male Infertility Involving Spermatogenic Arrest at Meiotic Prophase I in Humans and Mice

Advanced Science, Volume 11, Issue 33, September 4, 2024.
The findings identify HSF5 as a novel genetic cause for human male infertility associated with meiotic arrest. Moreover, the molecular mechanism of HSF5 is first unambiguously elucidated as a transcriptional regulator orchestrating the transcriptome to ensure meiotic progression in humans and mice.

Intracytoplasmic sperm injection outcome using ejaculated sperm and retrieved sperm in azoospermic men. [PDF]

, 2008
Introduction:We aimed to determine pregnancy and miscarriage rates following intracytoplasmic sperm injection (ICSI) cycles using retrieved epididymal and testicular sperm in azoospermic men and ejaculated sperm in oligospermic and normospermic men ...
