Penile biothesiometry - This test uses electromagnetic vibration to evaluate sensitivity and nerve function in the glans and shaft of the penis. A psychosocial examination using an interview and questionnaire may reveal psychological factors contributing to erectile dysfunction. The sexual partner also may be interviewed to determine expectations and perceptions encountered during sexual intercourse. What are intraurethral suppositories? Prostaglandin E1 (intraurethral alprostadil or MUSE) can be inserted in a pellet (suppository) form into the urethra to attain erections. This technique also is not popular because of occasional side effects of pain in the penis and sometimes in the testicles, mild urethral bleeding, dizziness, and vaginal itching in the sex partner. Men also need to remain standing after inserting the pellet in order to increase blood flow to the penis, and it may take 15-30 minutes to attain an erection. Prostaglandin can cause uterine contractions and should not be used by men having intercourse with pregnant women unless condoms or other barrier devices are used. This drug is now rarely used since the introduction of oral medications, however, it may play a role in management of erectile dysfunction in those who are not a candidate for oral PDE5 medications. buy levitra for sale online buy levitra for sale online Erectile Dysfunction Basics: Erectile dysfunction, commonly referred to as ED, is the inability to achieve and sustain an erection suitable for sexual intercourse. This condition is not necessarily considered normal at any age and is different from other problems that interfere with sexual intercourse, such as lack of sexual desire and problems with ejaculation and orgasm. Duplex ultrasound is used to evaluate blood flow, venous leak, signs of atherosclerosis, and scarring or calcification of erectile tissue. Injecting prostaglandin, a hormone-like stimulator produced in the body, induces erection. Ultrasound is then used to see vascular dilation and measure penile blood pressure.
