AI Article Synopsis
- The study investigates whether certain genetic variants linked to family size and birth rates in healthy men also affect sperm morphology in men facing infertility.
- Researchers analyzed sperm morphology in 126 ethnically diverse men and found two specific genetic variants (SNPs) associated with lower percentages of normal sperm morphology and increased sperm head defects.
- The findings suggest that these SNPs may point to important biological pathways affecting sperm production and male reproductive health, potentially helping identify new genetic factors involved in fertility.
Article Abstract
Purpose: Abnormalities in semen parameters are often associated with reduced fertility in males, and may, in part, be attributed to genetic variation. Aim of this study is to determine if genetic variants that were previously shown to be predictors of family size and birth rate in healthy men are also associated with sperm morphology in men recruited from an infertility laboratory.
Methods: Genetic associations with sperm morphology phenotypes in 126 ethnically diverse men from Chicago at 41 independent loci, previously shown to be predictors of family size and birth rate in healthy men, were tested.
Results: Two intronic SNPs, rs680730 (in DSCAML1) and rs10129954 (in DPF3), were associated with the percent of normal sperm morphology in Chicago men (P = 0.017 and 0.023, respectively). Furthermore, both loci were associated with increased occurrence of sperm head defects.
Conclusions: SNPs in two genes, both of which have roles in nervous system development, were associated with poor sperm morphology. These results may be helpful in identification of other novel genes and biological pathways whose proper functioning is crucial for sperm production and male reproductive processes.

Background: Herpes simplex virus type 2 (HSV-2) is a common sexually transmitted infection (STI) primarily acquired through sexual contact. In 2000, the World Health Organization (WHO) for the first time reported the association of STIs with male infertility. Infertility is described as the inability to achieve a clinical pregnancy after engaging in regular, unprotected sexual intercourse for a year or more.

Background: Tramadol, an opioid analgesic, is known to induce testicular damage and impair reproductive parameters. Vitamin D3, recognized for its antioxidant and protective properties, might offer a potential protective effect against tramadol-induced testicular damage. This study observed the effects of co-administration of vitamin D3 and tramadol on serum kisspeptin levels, testicular histology, semen parameters, testosterone levels, and oxidative stress markers in male rats.

Background: The massive harmful effects of cigarette (tobacco) smoking on reproduction and fecundity are apparent. Even smoking cessation is often suggested for infertility patients by clinic doctors, while the impact of smoking cessation on semen quality in patients with oligoasthenospermia is uncovered.
Methods: Ninety oligoasthenospermia patients with long tobacco smoking history were directed by andrology doctors to cease smoking, and their cessation was followed up for 3 to 6 months.

Background And Objectives: Epididymal transit renders key competence to mammalian spermatozoa for fertilizing eggs. Generally, the two paralogs of glycogen synthase kinase 3, GSK3α and GSK3β, functionally overlap except in testis and sperm. We showed that GSK3α is essential for epididymal sperm maturation and fertilization.

Background: In mammals, sperm fertilization potential relies on efficient progression within the female genital tract to reach and fertilize the oocyte. This fundamental property is supported by the flagellum, an evolutionarily conserved organelle, which contains dynein motor proteins that provide the mechanical force for sperm propulsion and motility. Primary motility of the sperm cells is acquired during their transit through the epididymis and hyperactivated motility is acquired throughout the journey in the female genital tract by a process called capacitation.
