The Impact of Lifestyle on Sperm Function, Telomere Length, and IVF Outcomes. | LitMetric

AI Article Synopsis

  • Many factors can affect sperm quality, including telomere length, which is linked to aging, cancer, and lifestyle choices.
  • The study analyzed how lifestyle habits (like diet, smoking, and physical activity) influence sperm telomere length and subsequently pregnancy outcomes in IVF patients.
  • Results showed that a healthy diet and more physical activity were associated with longer telomeres, while smoking negatively impacted sperm motility, emphasizing the importance of a healthy lifestyle for fertility.

Article Abstract

Many risk factors can potentially influence sperm quality. Telomeres confer stability on the chromosome and their dysfunction has been implicated in conditions such as cancer, aging, and lifestyle. The impact of lifestyle on sperm cell telomeres is unclear. The objectives of this study were to evaluate the impact of lifestyle behaviors on telomere length in sperm and to follow the correlation with pregnancy outcomes in patients undergoing in vitro fertilization (IVF). In this prospective observational study, sperm was analyzed for telomere length (TL). Men were asked to report lifestyle behaviors including occupation (physical or sedentary), smoking duration and amount, physical activity, dietary habits, and where they keep their cellular phone (bag, pants, or shirt pocket). Correlations among semen analysis, TL, men's habits, and embryo quality and pregnancy outcomes were evaluated. Among 34 patients recruited, 12 had longer TL and 13 shorter TL. Sperm motility was negatively correlated with TL (Pearson correlation = -.588, = .002). Smoking adversely affected native sperm motility (53% motility in nonsmokers vs. 37% in smokers; = .006). However, there was no significant impact on TL. The group with longer telomeres demonstrated significant association with healthy diet (10/12 vs. 6/13; = .05) and a trend toward more sports activity, weekly (16/84 vs. 7/91; = .04) compared with the shorter telomeres group. This study suggests that lifestyle, healthy diet, and sports activity are associated with long telomeres in sperm. Sperm quality is also influenced by patients' habits. The study strongly recommends maintaining a healthy lifestyle to preserve general health and fertility.
