3. 高潮期-無射精的性高潮
逆行性射精
在此介紹一種稱作逆行性射精的現象。在少數男性，他們的生殖管道平滑肌以這樣的一種方式運作：精液不是被射到體外，而是射進了膀胱，然後再從膀胱隨著尿液一起排出體外。從所有的外在證據看來，這種男性似乎根本就沒有射精。這種症狀可能是前列腺外科手術的併發症。但是，也有一些男性，他們宣稱能夠自主地操作肌肉達到這種特殊的射精，並用它作為一種避孕的手段。 |

左：在常規射精，平滑肌A關閉，平滑肌B打開，使精液可以通過尿道排出體外。右：在逆行性射精，平滑肌A打開，平滑肌B關閉，使精液不能通過尿道排出體外，而是使精液射進了膀胱。
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. | | |

3.
Orgasm - Orgasm without
Ejaculation Retrograde
Ejaculation
A special case is presented by a phenomenon
known as retrograde ejaculation. In a few men, certain
internal muscles operate in such a way that the semen is not
ejaculated to the outside, but instead into the bladder from
where it then later is passed off with the urine. From all
external evidence these men do not seem to ejaculate at all.
This condition can result from prostate surgery, but there are
also some men who claim to be able to achieve this particular
muscular reaction voluntarily and use it as a means of
contraception. | |
