Ejaculation

Retrograde ejaculation and infertility

Retrograde ejaculation is sometimes referred to as a "dry orgasm." Retrograde ejaculation is one cause of male infertility
Male infertility
Male infertility refers to the inability of a male to achieve a pregnancy in a fertile female. In humans it accounts for 40-50% of infertility. Male infertility is commonly due to deficiencies in the semen, and semen quality is used as a surrogate measure of male fecundity.-Pre-testicular...

Retrograde ejaculation can also be a complication of diabetes, especially in cases of diabetics with long term poor blood sugar control. This is due to neuropathy of the bladder sphincter.

It is currently not known whether a congenital malformation of the Bulbar Urethra is responsible, or if pressure applied to the base of the penis or perineum immediately preceding ejaculatory inevitability may have inadvertently damaged the urethra.

Potential treatments

The treatment depends on the cause. Medications may work for retrograde ejaculation but only in a few cases. Surgery rarely is the first option for retrograde ejaculation and the results have proven to be non-consistent. Medications do not help retrograde ejaculation if there has been permanent damage to the prostate or the testes from radiation. Medications also do not help if prostate surgery has resulted in damage to the muscles or nerve

These medications tighten the bladder neck muscles and prevent semen from going backwards into the bladder. However, the medications do have many side effects and they have to be taken at least 1–2 hours prior to sexual intercourse. In many cases, the medications fail to work at the right time because most men are not able to predict when they will have an orgasm.

 during orgasm. It was believed that doing this caused the sperm to travel into the head and nourish the brain, or that energy is conserved physically by keeping the sperm (and thereby, the "intelligence" that created it) in the body. This approach has since been discredited by modern medicine, as the retrograde-ejaculated sperm actually go into the bladder and are simply lost at the next urination. However, there are other Taoist perspectives on the general subject of ejaculation and techniques that do not involve retrograde ejaculation (see Taoist sexual practices
