Final answer:
Uncontrolled stress can indeed affect reproductive health, leading to menstrual irregularities, impotence, and pregnancy complications due to its impact on hormone balance.
Step-by-step explanation:
True, uncontrolled stress may lead to menstrual irregularities, impotence, and pregnancy complications. This is because stress can influence the body's hormone levels, which is crucial for reproductive functions. For females, short-term stress can impact hormone balance, while long-term stress can delay puberty and lead to less frequent menstrual cycles. These changes in hormone levels may contribute to menstrual irregularities and potentially affect fertility. For males, stress can also affect sexual function and lead to impotence. In terms of pregnancy complications, stress can increase the risk of certain health issues such as preterm labor or low birth weight.
