This is an accepted version of this page Epididymal hypertension (EH), informally referred to as blue balls for males or blue vulva for females, is a harmless but uncomfortable sensation in the genital regions during a prolonged state of sexual arousal.

[5] It most often describes a temporary fluid congestion in the testicles or vulva, caused by prolonged sexual arousal without orgasm.

Professor Caroline Pukall, who co-wrote the first in-depth study on EH, has suggested using the term throbbing crotch syndrome.

The treatment is to achieve orgasm, or alternatively strain to move a very heavy object—in essence doing a Valsalva maneuver.

[14] The cause of epididymal hypertension is a large amount of blood circulation to the genital area, specifically the penis and testicles, without the release of tension associated with orgasm and ejaculation.
