Cold showers increase blood flow to your brain, delivering a bumper hit of oxygen and nutrients that improve your concentration, alertness and mental clarity.
Cold showers have been shown to help improve male fertility, particularly so when taken regularly in the morning. The cold water helps to trigger testosterone, and research has proven that even a week's worth of cold morning showers can greatly maximize male sperm production.
Take it slow: Start with 30 seconds of cold water. Work up to a minute and progress until you take a cold shower for two to three minutes.
Cold showers and exposure to cold temperatures have been shown to increase testosterone levels, which can indirectly impact sperm count. Higher levels of testosterone can stimulate sperm production and increase the motility of sperm, which can improve overall sperm count.
“Testosterone hormone is secreted at night and rises in certain stages of sleep,” Dr Brewer explains. “If a man feels too hot and his sleep is disturbed as a result, his testosterone production may be reduced. Sleeping naked helps to promote a healthier sleep pattern, so normal testosterone production occurs.”
The short answer is there isn't a proven link between orgasms and testosterone levels, so we don't know how it affects you in the short term. However, you can take comfort in knowing that masturbating will not negatively affect your testosterone levels—or other aspects of your life—long-term.
Cold showers increase circulation and decrease inflammation, improving skin and hair health and appearance. Cold water also tightens skin pores. 4 Although there is plenty of anecdotal evidence on the benefits of cold showers for skin and hair, more research is needed.

The excitement and warm, fuzzy feeling of a new relationship may give your testosterone a boost. A 2015 study found that single men and men in new relationships had higher testosterone levels than men in long-term relationships.
This is because after the rush of orgasm, dopamine levels drop below baseline, similar to what happens during withdrawal from drugs of abuse. Low dopamine levels are associated with depression, low energy, lack of ambition, social anxiety, among others (Dailly et al., 2004).
According to some research, retaining sperm can boost testosterone levels by up to 45 percent in just a week. However, it returned to normal within a few days. Higher testosterone levels are associated with increased energy.
Currently, there's no proven link between orgasms — whether they're accomplished through sex or masturbation — and testosterone levels.

A vast number of pumps, pills, weights, exercises and surgeries claim to increase the length and width of your penis. However, there's little scientific support for nonsurgical methods to enlarge the penis. And no trusted medical organization endorses penis surgery for purely cosmetic reasons.
Results: Animal and preliminary human studies suggest that testosterone may facilitate erection by acting as vasodilator of the penile arterioles and cavernous sinusoids. Following castration, most, but not all, men had partial or complete loss of erection.
