Hi, this question would be for males castrated either surgically or chemically who have wife or girlfriend. Did any of your wife or girlfriend notice a change of body odor after being eunuch? Females are more sensitive about male body odor. Man can not tell if his own body odor change at all.

For meat animals, meat from intact males has distinct odor from castrated male or female animals, it must be related with high levels of T, that is related with body odor. In similar way, eunuchs may have different body odor, which can only be sensed by their closely lived female partners.

you can use trt,then your t level will not drop

My experience is that most male sweat has no odor when it is very fresh. But after puberty, male sweat aging smells much stronger than aging female or pre puberty male sweat. Male sweat definitely changes at puberty. Smelling male locker rooms used by pre puberty males vs male locker rooms used by after puberty males is very clear on how much more and stronger the smell of aging male sweat becomes during and after puberty. I suspect that locker rooms used by much older men with reduced levels of testosterone caused by old age would smell milder than the locker room sweat smells of teens and young men s locker rooms. Even though the smell of old sweat is caused by different kinds of bacteria growing in old sweat, male sweat after puberty definitely smells much stronger than old male sweat before puberty occurs.

A decrease in the smell and scent of eunuch sweat has been mentioned by eunuchs in past posts about various topics.

Male Body Odor Can Stink Like Urine Or Have A Pleasant Vanilla Smell, Depending On One Gene

Rockefeller University

Summary:

Why the same sweaty man smells sweet like vanilla to one person and repellent like urine to another comes down to the smeller's genes. Up to one-third of adult humans cannot perceive an odor in a component of male body odor that induces physiological responses in both men and women. To those who do, androstenone either takes on a pleasant sweet odor or a repulsive urine-like one. New research traces this variability to mutations in a single odorant receptor gene, a finding that raises questions of how people detect other people's body odor.

Scent of a Man: Women Can Sniff Out a Hot Guy

Women at their peak fertility prefer the smell of men oozing with testosterone, a new study finds.

Ovulation has been shown to impact a woman's mating preferences. For instance, women in the fertile phase of their menstrual cycle favor more masculine traits, such as a deep voice or manly face, characteristics associated with the hormone testosterone, studies have found. Other research suggests fertile women are attracted to men with high levels of the stress hormone cortisol, which may be involved in stronger immune systems.

In the new study, researchers tested how women's sexual scent preferences changed depending on men's levels of testosterone and cortisol. Male volunteers were given T-shirts to wear for two consecutive nights, during which time they were prohibited from using scented soaps or detergents; drinking or smoking; or eating garlic, onion, green chiles, strong cheeses and other pungent foods.

Then, female volunteers sniffed the men's shirts and rated the pleasantness, sexiness and intensity of the smells (on scales from 1 to 10). The women also completed a questionnaire about their stage in their menstrual cycles and whether they were using hormonal contraception.

The researchers took saliva samples from the men to measure hormone levels of testosterone and cortisol.

Women who were at the most fertile stage of their menstrual cycles preferred the smell of men with higher testosterone, rating these "manly" shirts as the most pleasant and sexiest, results showed. The women showed no preference for the smells of men with higher cortisol levels. Without taking the women's fertility into account, neither hormone had an influence on how attractive the men smelled.

The link found between testosterone and smell attractiveness contrasts with the findings of a previous study. That study sampled a smaller group of subjects (19 men versus the current study's 46 men), which could weaken the significance of the findings. However, that study tested for testosterone three times throughout the day, making it more sensitive to the hormone's frequent fluctuations.

"This is a controversial research area. Studies are highly inconsistent," psychologist Wendy Wood of the University of Southern California, who was not involved in the study, told LiveScience in an email. "Only a few studies have shown that women’s menstrual cycles influence their mate preferences — many more find no effects of menstrual cycles on preferences," Wood added.
