Sexual dysfunction rates of SSRI antidepressants r very high, there was a comprehensive study done about 10 years ago, looking at 4 of these drugs, examining pre-drug sexual function, then what happened over a time period on-drug. sexual dysfunction rates ran from 54-65%. One doctor decided to question his patients on Prozac. & suddenly found that 75% of them had some form of drug-induced sexual dysfunction.
There r occasional reports where the sexual dysfunction has remitted with a little time, but I've only come across a handful of them. It is usual for the dysfunction to continue throughout the use of the medication. The effects can be dose related, and, for some, lowering the dose may bring an increase in sexual function. however for others there is no return of function until the drug has been withdrawn. Rarely, it does not return.
Since u r on a relatively low dose (compared to the 20mg that many r started on) & have already encountered severe sexual effects, u may find the relevant chapter in Joseph Glenmullen is book on these antidepressant side-effects to be of interest (the book won a medical award). The book is 'Prozac Backlash', Chapter 3 covers the sexual dysfunction effects, plus the background, scientific studies, & possible approaches. note the pros & cons of adding another medication to counter the effects of the first. It is well worth getting the book out of a library, because the chapter is about 28ish pages long & should be able to provide u with to ur questions. It allows an individual to make an informed choice on the matter.
If u r a lady (?) & have the lowered libido, & anorgasmia. u may/may not find that u have reduced lubrication (loss of arousal), & possibly reduced genital sensation/numbness.
