This is 予定 the presence of androgen receptors, where testosterone 貯蔵所d, in areas of the brain that 過程 願望（する）. Without testosterone, there is nothing to signal arousal.?

Erectile dysfunction?

'You do need testosterone in order for a man to have an erection,' Dr Bernie said. 'If you have very low testosterone levels, it's very hard to get an erection.'?

While there has to be 増加するd 血 flow to the penis to 持続する an erection, testosterone is also necessary since there are receptors within erectile tissue, also known as the corpus cavernosum, inside the penis.

'Erectile tissue in someone who has low testosterone can atrophy or become いっそう少なく healthy,' Dr Bobby Najari, urologist at NYU Langone, told DailyMail.com.?

This leads 血 flow in the penis to become いっそう少なく responsive to 性の stimulation, he said. 欠如（する） of testosterone can also make 医薬s like Viagra いっそう少なく 効果的な.?

Low testosterone's 欠如（する） of libido can also 原因（となる） erectile dysfunction.?

不景気?

Low testosterone could 戦車／タンク your mood, Dr Najari said.

類似の to with sex 運動, androgen receptors are 設立する in several areas of the brain, 含むing the amygdala, which 過程s 恐れる.??

Memory 問題／発行するs

類似の to 不景気, androgen receptors could lead to poor memory. These receptors can be 設立する in the hippocampus, the part of the brain 責任がある learning and memory, 同様に as the cerebrum, which 支配（する）／統制するs thinking and 推論する／理由ing.

When there isn't enough of the hormone to 貯蔵所d to those receptors, it could lead to forgetfulness, Dr Bernie said.?

When there isn't enough of the hormone to 貯蔵所d to those receptors, it could lead to forgetfulness.

疲労，（軍の）雑役?

'Testosterone is our 最初の／主要な driver of 動機づけ and energy levels,' Dr Bernie said.

Testosterone is a diurnal hormone, meaning that it's highest in the morning and 徐々に 減少（する）s throughout the day.?

It's also a type of androgen hormone, a steroid, meaning that it keeps us energized.??

Since it 減少（する）s, men with low levels are going to be more tired throughout the day than those with normal levels.?

Testosterone 促進するs muscle growth and has been shown to 抑える fat 伸び（る）. When levels are low, muscle 集まり begins to dwindle, Dr Bernie said.??

In one 熟考する／考慮する from Japan, men with low levels of 解放する／自由な testosterone- the 量 of the hormone not bound to receptors- were two to three times more likely to have muscle loss with 高齢化 as those with normal levels.?

This is because lean muscle 集まり is 取って代わるd with fatty adipose tissue, also known as 団体／死体 fat.?

Having more fat tissue, 特に around the abdomen, can be a 調印する of low testosterone, Dr Najari said.?

This is 予定 to that fatty adipose tissue that 取って代わるs lean muscle 集まり.

One review in obese men 設立する that low testosterone 特に 増加するs fat deposits in the abdomen.

'One of the most ありふれた 推論する／理由s for lower testosterone, as men get older, is just 増加するing 量s of fat tissue that that break 負かす／撃墜する the testosterone,' Dr Najari said.?

Fat 独房s produce aromatase, an enzyme that 変えるs testosterone to estrogen. Estrogen then 原因（となる）s more fat to be deposited in the abdomen, 同様に as the chest, hips, and thighs.

'In men, testosterone is 変えるd into estrogen,' Dr Najari said. 'And we know, in both sexes, that estrogen is 伴う／関わるd in the 維持／整備 of bone health. So for men who have lower testosterone levels, they'll have lower estrogen levels.'

This 原因（となる）s the bones to thin or break 負かす／撃墜する. It can also lead to osteoporosis, a 条件 原因（となる）s by weak or brittle bones.?

'Insulin is testosterone 扶養家族, so you have to have some testosterone in your 団体／死体 in order for insulin to 機能（する）／行事 井戸／弁護士席,' Dr Bernie said.?

When insulin 機能（する）／行事 is impaired, it leads to poor 支配（する）／統制する of glucose, 主要な to high 血 sugar and 糖尿病.

A 2016 熟考する／考慮する in the 定期刊行物 糖尿病 Care 設立する that testosterone therapy could 減ずる insulin 抵抗 in diabetic men with low testosterone.?
