What is the ejaculatory reflex?

The ejaculatory reflex starts in the urethra and consists of a series of involuntary contractions that force the sperm out of the seminal vesicle and out of the penis. This reflex is controlled by the Pubococcygeus (PC) muscle.

 Is it possible to regain control over the ejaculatory reflex?

The control over the ejaculatory reflex can be completely regained in a simple manner and just as easy as any treatment to recover muscles. A precise exercise chronogram must be followed in order to achieve the correct operation of the PC muscle.

Even if my problem is caused by the imbalance between the serotonin and dopamine receptors, I also have to do these exercises?
