Metformin sexual side effects

It can reduce testosterone levels in males

Testosterone is a hormone produced in the testicles for males and ovaries for females.

It is the main androgen in the male body, meaning it is responsible for stimulating the development of male characteristics on the body.

Research suggests that metformin will likely reduce testosterone levels in the body of male diabetics.

Some tell-tale symptoms of  low testosterone include loss of body hair, difficulty with focusing and depressed mood.

You may experience erectile dysfunction

One of metformin sexual side effects is that it increases the likelihood of developing erectile dysfunction.

Erectile dysfunction occurs when a man is unable to get and maintain a firm erection during sex.

You may be lucky not to have developed erectile dysfunction from diabetes, but you should know that this drug also puts you at risk of developing it.

Most times, the erectile dysfunction is caused by a lower level of testosterone in the body, which is also one of metformin sexual side effects.

It may reduce sex drive in men

As a man, you run the risk of getting a lower sex drive if you take metformin regularly.

Lower sex drive will have you losing the desire to engage in sexual activity permanently or occasionally.

If you are particularly worried about this side effect, then you need to communicate those concerns to your doctor.

It can help normalize sexual desire in diabetic women

Premenopausal women with diabetes tend to experience low sex drive frequently.

This drug has been discovered to help improve sex drive in women, which is ironically the exact opposite of what it does in men.

Many diabetic women on metformin report improved sexual desire after a few months of using the drug.

It may get rid of pain during sex for diabetic women

Pain during sex, also known as dyspareunia, is a symptom commonly associated with diabetes and endometriosis.

Dyspareunia makes it difficult for women with these conditions to engage in sexual activity because it makes sex uncomfortable and unenjoyable.

Fortunately, research has found that metformin can help reduce this particular symptom and restore optimum sexual function in women.

It can get rid of vaginal dryness

Vaginal dryness is a problem is that a lot of diabetic women experience.

It varies in severity from one person to another, but it is generally uncomfortable for these women.

Additionally, it can make sex painful and difficult to enjoy.

Taking metformin to help manage diabetes can help get rid of this symptom, thankfully.

You can use any other available options for improving lubrication during sex, but when it comes to drugs like metformin, you need to ask your doctor first.

It can improve fertility in male patients with obesity

Interestingly, research shows that metformin can improve fertility in obese male patients who have metabolic syndrome.

Metabolic syndrome and obesity often lead to low levels of sex hormone-binding globulin (SHBG) and reduced testosterone levels.

When you use metformin to treat these two conditions, there is a high likelihood that the levels of SHBG will rise, which then causes a rise in testosterone levels as well.

Higher testosterone levels in turn improve fertility.

It may treat anorgasmia in diabetic women

Anorgasmia is a condition that delays or reduces the occurrence of orgasms during sex.

It is also characterized by absent or less-intense orgasms.

Anorgasmia is one of the most common forms of sexual dysfunction in women who have diabetes.

It can be treated in various ways including cognitive-behavioral therapy and sexual enhancement devices.

However, if you are already taking metformin you will probably not need any further treatment for the dysfunction.

This is because metformin can help optimize your sexual function, hence getting rid of anorgasmia while also normalizing your blood sugar levels.

Two birds with one stone, yeah?

It may improve fertility in women  with Polycystic Ovarian Syndrome (PCOS)

Women taking metformin for PCOS have a high chance of getting pregnant while on the drug.

One of metformin sexual side effects is that it can reduce testosterone levels in women with PCOS and normalize their menstrual cycle.

This may improve fertility and increase their chances of getting pregnant.

It can normalize sexual satisfaction in diabetic women

Normalizing sexual satisfaction is one of the ways through which metformin restores sexual function in diabetic women.

The more your insulin resistance reduces, the more likely it is for your sexual function to get back to normal.

How quickly does metformin lower testosterone?

Metformin takes about a month to normalize the levels of glucose in the body.

Within this period, it may reduce the levels of testosterone significantly.

The amount of time this drug may take to lower testosterone levels may vary from person to person.

However, the standard time is four or five weeks.

How can a diabetic overcome erectile dysfunction?

Erectile dysfunction is a pretty common symptom of advanced diabetes.

Fortunately, there are several options for managing it in diabetics – from oral drugs and injection therapy to penile pumps.

Oral medications work for most diabetics, but it is advisable that you seek your doctor’s opinion on what’s best for you.
