What issues may arise for males if body fat drops below essential values?

When body fat levels in males drop below essential values, one significant issue that can arise is thermoregulatory issues. Essential body fat is crucial for maintaining normal physiological functions, including regulating body temperature. Low levels of body fat can impair the body's ability to retain and dissipate heat, leading to increased risk of overheating or hypothermia.

Essential body fat acts as insulation and provides necessary cushioning for organs, which plays a role in heat retention. Without adequate body fat, males may struggle to maintain their core temperature during physical activity or in varying environmental conditions. This can result in complications such as heat exhaustion or an inability to maintain performance levels in extreme weather conditions.

The other options do not directly address the physiological complications linked to very low body fat levels. Instead, they refer to effects that might be seen with moderate or optimal body fat levels, rather than the detrimental impacts associated with going below essential fat thresholds.
