Smoking impacts male and female fertility

A scientific study from two British universities has found that smoking affects reproductive function through molecular changes in reproductive tissues. The study showed that exposing mice to cigarette smoke for 12 weeks led to genetic changes similar to those associated with reproductive aging and decreased ovarian function in females, with no significant changes observed in ovarian structure. In males, high exposure to cigarette smoke caused testicular swelling and genetic alterations related to sperm production and immune response, indicating an impact on testicular function. The results highlight that smoking causes molecular biological changes that may explain the link between smoking and infertility, emphasizing the need for further research to understand its effects on human fertility.
