Androgen Sensitivity in Male Lions during extended mating
The bolded was taken from AI overview:
No, sex does not lower androgen (testosterone) sensitivity in male lions. While frequent mating can temporarily exhaust a male lion's energy, biological sensitivity to androgens remains stable. In fact, androgens govern the size and darkness of a lion's mane, which helps females select mates
The Science of Lion Androgens
Testosterone and the Mane: A lion's mane is highly sensitive to testosterone. Higher androgen levels lead to darker, fuller manes, which signal a male's health, fighting ability, and genetic strength to females.
Receptor Sensitivity: There is no scientific evidence that mating down-regulates or lowers androgen receptors (sensitivity to testosterone) in male lions. Receptor sensitivity remains consistent throughout their prime.
The "Challenge Hypothesis": Rather than dropping after sex, a male lion's testosterone naturally surges during the mating season to help him compete with rival males and fend off challenges to his pride.
The Cost of Mating
While their hormonal sensitivity stays intact, the physical act of sex in lions is incredibly demanding. Lions mate continuously for several days—sometimes copulating up to 50 times in a 24-hour period. This marathon effort results in temporary physical exhaustion, weight loss, and a short-term dip in general stamina, but this is a matter of physical fatigue rather than a change in hormone sensitivity.
Key points here:
- androgen receptor sensitivity is genetic and tied to age and environmental factors (diet, sleep, etc);
- testosterone increases during the mating season due to both violent fights between males for dominance, and high testosterone being necessary to have sex with females up to 50 times in a single day for several days (very high testosterone lowers refractory period and increases sex drive);
- the lions do get tired: but they get tired from lack of sleep, lack of eating food and drink due to fucking so much, etc...kind of like how humans tend to not get as much sleep when they are having sex all night, and then blame the supposed "hangover" they have the next day on the sex instead of said lack of sleep.
The verdict: being around attractive girls and competitive social situations is beneficial for testosterone and energy levels. And androgen receptor activity is determined by genetics, good diet and good sleep, and keeping pollutants to a minimum.
