when a man is unable to sustain an erection, it is generally because the valves in the veins draining from the penis have become incompetent. This may be due to a deficiency in the vascular system but is more frequently because the male is taking some medication to open the vessels and reduce blood pressure. If a man suffers from premature ejaculation the penis usually undergoes a ‘collapse’ as the blood drains out of the penis, but the sperm is still viable and a woman may still be impregnated. Age plays a role in all the above problems for men but all of these situations can be managed by an andrologist, a urologist or occasionally a psychologist who deals with sexual dysfunction.
