Can Cold or Heat Boost Testosterone Levels?

With ground-hog day approaching, and a longing for spring, seems apt to throw some light on how temperature affects testosterone levels right?

Cold Showers Boost Testosterone?

A cold shower might invigorate, improve blood circulation, give a glowing skin but it does not boost testosterone levels.

If it is a hot day or you had a vigorous workout, a cold shower will soothe sore muscles, cool down body temperature, including the testicles which is good for sperm quality. The testicles always are at a slightly lower temperature than the body.

In fact scrotal descent, and the way arteries that supply blood to the scrotum are right next to the veins taking blood away from the scrotum is a mechanism to regulate temperature. This evolutionary adaptation along with the thin scrotal skin, has led to scrotal temperature in humans 2.5 to 3 degrees Celsius lower than body temperature. Sperm generation works well at 34 degrees Celsius.

Taking a cold shower before bed will improve sleep quality which in turn might boost testosterone. Testosterone levels peak early in the morning and a bit in the afternoon.

Stress at work or in life is weighing you down? Working out followed by a cold shower or alternating cold and hot shower should help sleep quality which is a casualty of stress. A sound sleep in turn boosts testosterone.

Cold Stimulation or Exercise for a Testosterone Boost?

A study that compared serum testosterone level between cold stimulation and physical exercise clearly showed that exercise boosted serum T-levels, by increasing luteinizing hormone and Noradrenaline levels.

Finasteride restores Male Pattern Baldness hair loss by boosting the growth phase of the hair cycle called the anagen phase. Many studies demonstrate the efficacy of finasteride to regrow hair lost from Male Pattern Baldness (MPB). In one such study: Treatment with finasteride 1 mg day−1 for 48 weeks increased both total and anagen hair counts, and improved the anagen to telogen ratio. “Conclusions These data provide direc t  evidence that finasteride 1 mg daily promotes the conversion of hairs into the anagen phase. These data support that finasteride treatment results in favorable effects on hair quality that contribute to the visible improvements in hair growth observed in treated patients.” ​ So What are the Anagen & Telogen Phases? The growth of scalp hair is a cyclical process of successive phases of growth (anagen) and rest (telogen). The growth rate varies individually and other factors — genetics, age, environmental, level of abuse using chemicals etc play a part. Hair can

Finasteride is both Pill and topical application, and works only on androgenic alopecia (male pattern baldness.) ​ Minoxidil is a vasodilator.

Finasteride is an enzyme blocker which reduces a potent form of testosterone — DHT which causes MPB, the most common cause of hair loss in men and women. ​ Minoxidil thic k ens the hair shaft, and can increase density, whereas finasteride stops miniaturization of the hair shaft due to DHT and stabilizes hair loss. ​ Minoxidil elongates growth phase, finasteride stops hair going into rest phase due to miniaturization or shrinking of hair shaft. ​ Minoxidil least effective to treat  frontal baldness . Finasteride can effectively treat receding front line.​ Minoxidil will result in increased hair everywhere. In fa
