Sexual sensation depends on a complex network of nerves that carry signals between the reproductive organs, spinal cord, and brain.

Some men notice that stimulation feels different as they age or that achieving an erection or orgasm takes longer.

These changes can have several causes.

Diabetes, for example, can damage peripheral nerves and affect sensation. Certain medications, neurological conditions, and previous pelvic surgery can also influence sexual response.

Normal aging may contribute to changes in responsiveness, but substantial numbness or a sudden loss of sensation should not be considered an ordinary part of growing older.

It is also important to remember that sexual satisfaction is not determined solely by physical sensitivity.

Emotional connection, communication, overall health, and psychological well-being can all influence sexual experiences.

7. The Testicles May Change as Well

Although attention often focuses on the penis, the testicles can also undergo age-related changes.

The testicles produce testosterone and sperm. Their function is regulated by a complex hormonal system involving the brain and reproductive organs.

As men age, sperm production and reproductive hormone levels may change.

Some men may also notice changes in testicular size or firmness.

However, a new lump, persistent pain, significant swelling, or a sudden change in one testicle should never be assumed to be a normal consequence of aging.

These symptoms require medical assessment because they may be associated with infections, fluid collections, other treatable conditions, or, less commonly, cancer.

8. Fertility Can Change Even When Sexual Function Remains Normal

Many people associate reproductive aging primarily with women, but male fertility can also change over time.

Men can continue producing sperm throughout much of their lives. Nevertheless, increasing paternal age has been associated with changes in certain measures of sperm quality and reproductive outcomes.

These changes do not mean that older men are necessarily infertile.

Many men become fathers later in life.

However, the ability to achieve an erection and the ability to conceive are not the same thing.

A man can have satisfactory sexual function while experiencing fertility difficulties, just as someone can experience erectile problems without necessarily having impaired sperm production.

Couples experiencing difficulty conceiving should seek appropriate medical advice rather than assuming age is the only explanation.

9. The Prostate Becomes Increasingly Important With Age

Another significant change in male reproductive and urinary health involves the prostate.

The prostate is a gland located below the bladder that surrounds part of the urethra.
