Sexual dysfunction in Parkinson's disease.

Sexual dysfunction is common in Parkinson's disease (PD). We investigated the premorbid and present sexual functioning of 75 people with PD (32 women and 43 men). Women reported difficulties with arousal (87.5%), with reaching orgasm (75.0%), with low sexual desire (46.9%), and wih sexual dissatisfaction (37.5%). Men reported erectile dysfunction (68.4%), sexual dissatisfaction (65.1%), premature ejaculation (40.6%), and difficulties reaching orgasm (39.5%). Premorbid sexual dysfunction may contribute to cessation of sexual activity during the course of the disease (among 23.3% men and 21.9% women). Associated illnesses, use of medications, and advanced stage of PD contributed to sexual dysfunction.
