High‐Resolution Imaging Reveals Mitochondrial Protein Imbalance in Sperm of Oligoasthenospermic Men

Molecular Reproduction and Development, Volume 93, Issue 5, May 2026.
ABSTRACT Male infertility accounts for nearly half of global infertility cases and is often linked to poor sperm quality, such as oligospermia, asthenospermia, and teratospermia. Although the exact mechanisms remain unclear, mitochondria, which are critical for ATP production and reactive oxygen species generation during fertilization, are increasingly

Relationship of morphology and chromatin integrity of sperm in aneuploid blastocyst development: embryos fertilized with sperm diagnosed with teratozoospermia

Obstetrics & Gynecology International Journal, 2023
Objective: Evaluate whether the presence of aneuploid blastocysts is associated with sperm morphology and fragmentation. Methods: Retrospective, observational and cross-sectional study, which included 352 embryos in blastocyst stage, obtained by ...

Lack of testicular seipin causes teratozoospermia syndrome in men [PDF]

Proceedings of the National Academy of Sciences, 2014
Significance The relationship between body fat and male reproduction is clearly seen when excess fat compromises fertility; however, potential consequences of adipose tissue paucity on fertility are unclear. We report that lack of seipin, a transmembrane protein localizing to the endoplasmic reticulum, causes both paucity of adipose tissue ...

Pharmacogenetics of follicle‐stimulating hormone action in the male

Andrology, Volume 14, Issue 4, Page 1064-1072, May 2026.
Abstract Male factor infertility (MFI) is involved in half of the cases of couple infertility. The follicle‐stimulating hormone (FSH) therapy is considered efficient to improve semen parameters and pregnancy rate in patients with idiopathic MFI, following the lesson learned from hypogonadotropic hypogonadism.

Teratozoospermia Classification Based on the Shape of Sperm Head Using OTSU Threshold and Decision Tree [PDF]

, 2016
Teratozoospermia is one of the results of expert analysis of male infertility, by conducting lab tests microscopically to determine the morphology of spermatozoa, one of which is the normal and abnormal form of the head of spermatozoa.

Teratozoospermia influences fertilization rate in vitro but not embryo quality [PDF]

Human Reproduction, 1997
The purpose of this study was to retrospectively compare the overall results and embryo quality in 102 cycles of in-vitro fertilization (IVF)-embryo transfer using normal frozen donor semen (group D) and 94 cycles of IVF-embryo transfer using husbands' teratozoospermic sperm (group T). Donor semen was purchased from men with proven fertility and normal

Addition of Multi‐Level Technologies to Evaluate Eggs and Embryos and Improve Endometrial Quality Applied for In Vitro Fertilization to Achieve Pregnancy: A Case Study

Clinical Case Reports, Volume 14, Issue 3, March 2026.
This integrated clinical approach optimizes the reproductive cycle in several steps, starting with nutrition (A): restricting carbohydrates and inducing ketosis to reduce inflammation and improve insulin sensitivity, which benefits follicular development.

DNA fragmentation and chromatin denaturation in various sperm categories: A prospective cohort study

Asian Pacific Journal of Reproduction
Objective: To evaluate how DNA fragmentation index (DFT) and chromatin denaturation index (CDI) relate to semen parameters across different types of male infertility, thereby improving the understanding and assessment of sperm quality.

Associations Between Reproductive Disorders and Specific Physical, Mental, Personality, and Social Characteristics: A Narrative Review

Health Science Reports, Volume 9, Issue 3, March 2026.
ABSTRACT Background and Aims The present review aims to ascertain whether reproductive disorders are associated with specific physical, mental, personality, and social traits. This information may be used to support or reject the hypothesis on the origin of infecundity, which proposes that women/men with preferred characteristics, including high ...

High incidence of oligozoospermia and teratozoospermia in human semen infected with the aerobic bacterium Streptococcus faecalis [PDF]

, 2002
Bacterial culture of semen samples from 100 male partners in infertile couples revealed the presence of aerobic bacteria in 49 cases. Streptococcus faecalis (Enterococcus) was isolated from 53%, micrococci species from 20% and α-haemolytic ...
