Is varicocoelectomy indicated in infertile men with isolated teratozoospermia? a systematic review and meta‐analysis

Andrology
Clinical palpable varicocoeles in conjunction with isolated teratozoospermia are rarely observed. Therefore, the effects of varicocoelectomy on sperm morphology are not clear.

The relationship between DNA fragmentation and the intensity of morphologically abnormal human spermatozoa

Asian Pacific Journal of Reproduction
Objective: To determine the relationship between teratozoospermia and sperm DNA fragmentation (SDF) in the human ejaculate. Methods: This retrospective study included 100 normozoospermic men as a control cohort (abnormal forms >14%), 210 patients with a ...

Long‐Read Sequencing of CAH and ADPKD Provides Novel Insights Into the Genetic Diagnosis of Male Infertility

Reproductive Medicine and Biology, Volume 25, Issue 1, January/December 2026.
ABSTRACT Purpose This study aimed to evaluate the utility of long‐read sequencing (LRS) in identifying variants of congenital adrenal hyperplasia (CAH) and autosomal dominant polycystic kidney disease (ADPKD) in infertile men, which may help further clarify genetic diagnosis and support genetic counseling and reproductive management. Methods A total of

Severe teratozoospermia and its influence on pronuclear morphology, embryonic cleavage and compaction [PDF]

, 2011
Background Fertilization, cell division and embryo development depend on genomic contributions from male and female gametes. We hypothesize that teratozoospermic sperm influences early embryo development and embryo compaction.

Advances in the Diagnosis of Reproductive Disorders in Male Camelids

Animals
Male fertility is important to ensure herd health and productivity. The camelid male breeding soundness examination (BSE) is strongly recommended because natural mating remains the primary breeding method due to the challenges in semen cryopreservation ...

Therapeutic Potential of Myo-Inositol in Male Infertility: Correction of Spermatogenesis Parameters and Oxidative Stress (Review)

Безопасность и риск фармакотерапии
INTRODUCTION. Male infertility, in particular reproductive system deficiency, is often associated with oxidative stress. Myo-inositol antioxidant properties are essential for various biochemical and cellular processes in spermatozoa; for example, they ...

Exploratory Multiomics Profiling Reveals ACTN4‐Centric Cytoskeletal Failure and Environmental Arsenic Association in Morphologically Defined Oligoasthenoteratospermia Subtypes

Andrologia, Volume 2026, Issue 1, 2026.
Background Oligoasthenoteratospermia (OAT) represents a major cause of male infertility. The molecular mechanisms underlying sperm morphological defects, particularly their potential interplay with environmental exposure‐associated molecular alterations, remain poorly understood and warrant exploratory investigation.

P-111 Artificial Oocyte Activation (AOA) through piezoelectric stimulation post-Intracytoplasmic Sperm Injection (ICSI) for teratozoospermia patients

Human Reproduction
Does employing piezoelectric stimulation on oocytes post-ICSI in teratozoospermia cases affect early embryonic development rates? In a retrospective study, piezoelectric stimulation after ICSI showed increased fertilization rates and ...

Implications of Advanced Sperm Selection Techniques in Assisted Reproductive Program: A Systematic Review

Andrologia, Volume 2026, Issue 1, 2026.
The quality of the spermatozoa likely influences embryo development and subsequent pregnancy outcomes. Advanced sperm selection techniques choose viable, mature, and structurally intact sperm with high DNA integrity for fertilization. This review study aimed to determine whether there is evidence on the overall benefit of these techniques on the ...
