成人期的閹割
在成年期，閹割的後果與青春期是不同的：儘管被閹割者不能生育，但是他的性能力、性動機和性行為實施能力並不會必然地喪失。最後，他將在相當程度上經歷逐漸喪失這些能力的過程；但是，在性心理和性的社會交往方面，他可能仍然能夠將他早期的性體驗（sexual scripts）付諸於行動之中。因為患睾丸癌和其他疾病，在成年期切除睾丸則是必要的。

對性侵犯者進行的閹割
經由法律授權，閹割有時也是合法的，它被用來對付那些性侵犯者。最近幾年裏，對付性侵犯者的外科閹割日益被稱之為化學或激素閹割所替代。像去乙醯環丙氯地孕酮醋酸鹽的物質被用來抑制性腺激素的分泌。當然，停止使用這種抑制劑，這種類型的“閹割”則會逆轉。

Castration in adulthood 
In an adult, castration has a different effect: He also becomes infertile, but his sexual capacity, motivation, and performance do not necessarily come to an immediate end. In the long run, he will experience a considerable reduction in all of these areas, but on the psychosocial level he may still be able to act out some of his earlier sexual scripts. A castration in adults can become necessary because of testicular cancer and other diseases.

Castration of sex offenders
Castration has sometimes also been authorized by the legal authorities to be applied to violant sex offenders. In recent years, the surgical castration of sex offenders has increasingly been replaced by the so-called chemical or hormonal castration. Substances like cyproterone acetate are used to suppress the gonadal hormone production. This kind of 'castration' is, of course, reversible by discontinuing the treatment.
