There is almost no man who has never thought of achieving an erection. What is it that “raises pride” and that makes the male reproductive organ large and strong? If you are one of those who want to know what happens when it “starts to grow”, stay with us and read what we have prepared for you.

How does an erection occur?

Any irresistible sexual stimulus ignites the nerve signalling that quickly reaches the penis through the spinal cord, and then the nerve roots in the lower vertebrae. Nitric oxide is released there, stimulating the rush of blood needed for healthy erections. If erections occur in the brain and are born in the penis, orgasms go in the opposite direction. Sensory stimuli of the erect penis and surrounding tissue cause the sensory nerves to fire signals that travel through the spinal cord to the brain.

And to orgasm?

The more and more nerve stimuli come from the genitals to the thalamus, the more dopamine neurotransmitters gradually accumulate, as if a little gas is leaking from the stove. When enough fuel accumulates, the thalamus explodes. This sudden effect spreads to the rest of the brain.

Part of that wave are signals to the nerves that travel to the pelvis. They coordinate the contraction of the muscles of the bottom of the pelvis, prostate, seminal vesicles and vas deferens in the process of ejaculation by which the semen and semen fluid is expelled through the urethra out of the body.

The other part of the explosion happened at the same time. When the regions of the brain that feel pleasure are activated, an orgasmic response occurs.

Are Ejaculation And Orgasm The Same?

Most times ejaculation and orgasm happen so well synchronized that most men think it’s one and the same. It’s not. Depending on the problem of nerve signal conduction and chemical conduction, men can have an orgasm without ejaculation and ejaculation without orgasm. Or neither.

Because the brain is an inseparable part of the complex system that makes reproduction possible and full of enjoyment, anything that changes the chemistry in our brain — whether it’s a bad mood or medication — can affect erections, ejaculation and orgasm. For example, as we already know, the compounds in charge of choosing “fight or flight” prepare us for action in life, not in bed. Fear activates our nervous system to produce a chemical called norepinephrine, and it immediately stops erecting. Only when your stress level drops and allows sedative chemicals, such as acetylcholine, to prevail, can smooth muscles relax enough to allow an erection. Being “in the mood” means, in other words, more than a phrase: it is a necessary part of our physiology.

Don’t be depressed

For reasons never fully explained, men with chronic mood disorders, such as clinical depression, often suffer from erectile dysfunction. Depression medications, antidepressants that target the mood neurotransmitter, serotonin, have helped many men get out of a bad mood, but it has cost them masculinity. Side effects of drugs that selectively inhibit serotonin reuptake include erectile dysfunction or decreased libido or delayed ejaculation or anorgasmia.

Concomitant effects of antidepressants on the genital system are very common. In men who treat depression, these side effects are the main reason why they stop drinking them.

It is a depressing choice: one’s own sex life or desire for life. Fortunately, there is a promising alternative: bupropion, an effective antidepressant that acts on the composition of dopamine, not serotonin. Doctors who deal with this problem state that they have never seen sexual dysfunctions in patients treated with bupropion. On the contrary, they mentioned stories that could sometimes mean that he improved their libido. These patients are often very satisfied.
