逆行射精
最後,需要提及的是,某些男子會達到沒有看得見射精的性高潮。顯然,這不會有性高潮問題,然而,嚴格地說,這個議題不屬於本講的範疇。不過,為了完整起見,在此作一簡要概述:
極有可能男性會發生沒有看得見射精的性高潮,因為精液被射入了膀胱。這種所謂的“逆行射精” 會在前列腺外科手術或服用某些藥物後發生,不過仍有某些男性宣稱能夠訓練自己按照意願達到逆行射精,以作為避孕的手段。不管怎樣,精液隨後會隨著尿液排出體外。
左圖:常規射精,括約肌A關閉,而括約肌B打開,使精液有可能被壓力推進到尿道而射出體外。  
右圖:逆行射精,括約肌A打開,而括約肌B關閉,使精液不可能被壓力推進到尿道而排出體外。精液而是被射進了膀胱。

Left: For a regular ejaculation, muscle A closes and muscle B opens, making it possible for the semen to be propelled through the urethra to the outside.
Right: In a retrograde ejaculation, muscle A opens and muscle B closes, making it impossible for the semen to be propelled through the urethra to the outside. Instead, it is ejaculated into the urinary bladder.

Retrograde Ejaculation
Finally, it needs to be mentioned that some men reach orgasm without visible ejaculation. This is obviously not a problem of orgasm and thus, strictly speaking, its discussion does not belong here. Nevertheless, for the sake of completeness, here is a brief description:
It is possible that a man's orgasm produces no visible ejaculation, because the semen is ejaculated into the urinary bladder. This so-called "retrograde ejaculation" can occur as a result of prostatic surgery or of taking certain medications, but there also some men who claim to be able to train themselves to achieve voluntary retrograde ejaculations as a means of contraception. In any case, the semen is later simply discharged with the urine.
