It's a well known fact that a man's sexual function declines with age, but there is no expiry date of Sex. As man's testosterone level falls, it takes more to arouse him. Once aroused, he takes longer to get an erection and to achieve orgasm and, following orgasm, to become aroused again. Age brings marked declines in semen volume and sperm quality. Erectile Dysfunction is clearly linked to advancing years; between the ages of 40 and 70, the percentage of potent men falls from 60% to roughly 30%. Men also experience a gradual decline in urinary function.
And that not at all. Recent research confirms what men have long suspected and in some cases, feared; that the penis itself undergoes significant changes as a man moves from his sexual prime-around age 30 for most guys-into middle age and onwards - these changes include.
There are two major changes. The head of the penis (glans) gradually loses its purplish color, the result of reduced blood flow and there is a slow loss of Pubic Hair. "As testosterone wanes, the penis gradually reverts to its Prepubertal, mostly hairless state.”
Weight gain is common as men grow older. As fat accumulates on the lower abdomen, the apparent size of the penis changes. Large prepubic fat pad makes the penile shaft look shorter, some cases, abdominal fat all but buries penis, one way I motivate my overweight patients is by telling them that they can appear to gain up to an inch is size simple by losing weight. Most of the men would do anything to increase size of penis!!!
In addition to this apparent shrinkage (which is reversible) the penis tends to undergo an actual (and irreversible) reduction in size. The reduction "in both length and thickness - typically is not dramatic but may be noticeable. If a man's erect penis is 6 inches long when he is in his 30, it might be 5 or 5.5 inches when he reaches his 60s or 70s.
What causes the penis to shrink? At least two mechanisms are involved. One is slow deposition of fatty substances inside tiny arteries in the penis, which impairs blood flow to the organ. This process known as Atherosclerosis is the same one that contributes to blockages inside the coronary arteries - a leading cause of heart attack. Second mechanism involves the gradual buildup of relatively inelastic collagen (scar tissue) within the stretchy fibrous sheath that surrounds the erection chambers. Erections occur when these chambers fill with blood. Blockages within the penile arteries - and increasingly inelastic chambers - mean smaller erections.
As penis size changes, so do the testicles. Starting around age 40, the testicles definitely begin to shrink. The testicles of 30 year old might measure 30 mms in diameter, those of a 60 year old-perhaps only 20 mms.
If penile scar tissue accumulates unevenly, the penis can become curved. This condition, known as Peyronie disease, occurs most commonly in middle age. It can cause painful erections and make intercourse difficult. The condition may require surgery.
Numerous studies have shown that the penis becomes less sensitive over time. This can make it hard to achieve an erection and to have an orgasm. Whether it renders orgasm less pleasurable remains an open question.
The most important ingredient for a satisfying sex life is the ability to satisfy your partner, and that doesn't require peak sexual performance or a big penis. As long as a man's partner enjoys sexual intercourse, he feels like a god!
