How Likely Is ED Caused by MK677 and Increased Prolactin?

MK-677 is a drug that appears to be effective at increasing levels of prolactin, the hormone responsible for milk production in females.

Research into the effects of MK677 on humans indicates that taking it increases serum prolactin by 27%, although this decrease back to baseline occurs shortly after ceasing treatment.

Although MK677 may have positive uses in terms of milk production and bone health, it can have negative side effects in males such as gynecomastia, low sex drive and erectile dysfunction if too much is taken due to its effect on prolactin.

It is important to consider all potential outcomes when contemplating using MK677.

Despite the exceedingly rare nature of MK 677 causing erectile dysfunction, some men may have an increased likelihood of experiencing this side effect depending on their baselines.

Men with lower testosterone levels and higher prolactin levels or histories of erectile issues should conduct bloodwork to check and make sure their baselines are within the recommended ranges.

Fortunately, for men whose hormone levels remain within a healthy scope, peril from any prolactin-related side effects due to MK 677 is minimal, if any at all.

To safeguard against any potential risks or issues as associated with taking MK 677, there are a few preventive measures in place that should be explored thoroughly.

The Real Reason for Erectile Dysfunction
