In this, I'm not discussing any particular attainment, but: After 50 odd years practising Theravada, including some 20 odd years in a Forest environment, during which there was the endless fear of erection, I unwittingly developed techniques for reversing the energy flow back to the origin of sensation, based on [mis]conceptions of Kundalini. The upshot of which is that whilst recently having returned to lay status and thus permitted relationships in accord with the third precept - Kamesu micchacara - I am now permanently incapable of erection.

There is evidence that an arahant has undergone such transformation in body chemistry that he has gone beyond the dichotomy of masculinity and femininity. All normal physiological sexual functions seem to be atrophied in an arahant as it is said that seminal emission is impossible for an arahant even in sleep.32 We may also note the tradition maintaining that arahants never dream,33 maybe because they have attained such perfect mental health that there is no necessity to release tension through dreams.
The footnote is a reference to the Vinaya, in the section "allowance for a sitting-cloth (Vin 1.295)":
Thus it is, Ānanda, thus it is, Ānanda, that when they fell asleep, thoughtless, careless, impurity was emitted as the result of a dream. Ānanda, those monks who fall asleep calling up mindfulness, careful, by these impurity is not emitted; and, Ānanda, those who are ordinary people, passionless in regard to pleasures of the senses, by these impurity is not emitted. It is impossible, it cannot come to pass, Ānanda, that impurity should be emitted by one perfected.”
