Q: How important is sleep?

A: Sleep is incredibly important, and can be considered crucial alongside diet and exercise. Proper sleep habits help sustain many biological processes, and bad sleep can cause these processes to be suboptimal or even malfunction.

Q: Does creatine cause baldness?

A: It is plausible. Creatine increases DHT and DHT is implicated in the pathology and a receding hair line. No direct studies have been conducted assessing the connection

Q: What is 'roid rage'?

A: Mostly a myth; testosterone (including injections) can increase impulsivity in some but this does not appear to be reliable (does not affect every person tested), impulsivity might lead to aggression but this is drawing at straws now with the connections

Q: How can I increase testosterone naturally?

A: Most 'testosterone boosters' you find simply boost your libido without actually boosting your testosterone levels. You can boost testosterone if you are below baseline.

Q: Do herbal aphrodisiacs work?

A: It depends on the product touted to be an aprhodisiac, but some of them do apparently increase sexual desire; it is a relatively underresearched topic though, and we don't know why they increase sexuality

Q: Does ashwagandha increase testosterone?

A: Ashwagandha, an herb from traditional Indian medicine, has a bit of evidence for increasing testosterone but it is not overly convincing at this time.

Q: Does ejaculation affect testosterone levels?

A: Ejaculation results in changes in prolactin (increase) and dopamine (temporary decrease), but does not result in changes in testosterone. Although prolactin and dopamine are both involved with testosterone, they do not appear to influence testosterone levels acutely.

Q: Is semen high in protein?

A: Yes. Semen is 50% protein by weight and contains a variety of nutrients to protect the sperm cells from damages.
