• B. They are not relevant.
• C. They replace medical treatment.
• D. They only affect female partners.

Answer: (A)

Lifestyle factors are considered because they can directly affect how easily conception occurs and how successful infertility treatments are. They influence the hormonal balance that drives ovulation, the quality of eggs and sperm, and the receptivity of the uterus to implantation. For example, smoking is known to reduce ovarian reserve and lower the chances of success with treatments like IVF. Obesity or being underweight can disrupt menstrual cycles and ovulation, and can also blunt response to medications used for ovulation induction or assisted reproduction. Alcohol use, poor nutrition, sleep disturbances, high stress, and excessive caffeine or exertion can all disturb hormonal regulation and gamete quality. In men, lifestyle factors such as smoking, obesity, and heat exposure can impair sperm count and function. By addressing these factors—weight management, smoking cessation, moderated alcohol intake, balanced nutrition, regular moderate exercise, and reducing environmental exposures—fertility can improve and treatments can work more effectively. Importantly, lifestyle changes complement medical therapy; they do not replace it and they apply to both partners.
