Treatment and safety
Are compounded semaglutide and tirzepatide FDA approved?
No. Compounded semaglutide and tirzepatide products are not FDA-approved, and FDA does not review them for safety, effectiveness or quality before they are marketed.

Are generic sildenafil and tadalafil as effective as Viagra and Cialis?
FDA-approved generics contain the same active ingredient and must meet the same standards for strength, quality and performance as the brand-name medicines.
Treatment and safety
Can erectile dysfunction be a sign of heart or blood vessel problems?
Sometimes. ED shares risk factors with heart disease, such as diabetes, high blood pressure and smoking, so guidelines recommend looking at overall cardiovascular health.
Treatment and safety
Can I take testosterone if I am planning to have children in the next few years?
Standard testosterone replacement therapy is generally not recommended if you are planning to have children soon, as it significantly suppresses sperm production.

Can I take testosterone if I've had blood clots?
Tell your clinician first. Testosterone labeling warns about blood clots, and TRAVERSE found more pulmonary embolism with testosterone, so a past clot needs careful review.
Treatment and safety
Can testosterone therapy affect blood pressure?
Some testosterone products can raise blood pressure, and the FDA's 2025 labeling update addresses blood pressure across testosterone products. Blood pressure is checked as part of follow-up.
Treatment and safety
Can testosterone therapy affect sleep apnea?
The Endocrine Society guideline recommends against starting testosterone in men with untreated severe obstructive sleep apnea. If you snore heavily or stop breathing at night, mention it before treatment.
Treatment and safety
Does alcohol affect how ED medicines work?
Heavy drinking can make erections harder and, combined with sildenafil or tadalafil, can increase the chance of dizziness or a drop in blood pressure. Moderation is the safer approach.
Treatment and safety
Does testosterone therapy affect fertility?
Yes. Testosterone therapy typically suppresses the body's own hormone signaling and can substantially reduce sperm production, so it should not be started casually by a man who hopes to father children in the near term.

Does testosterone therapy treat erectile dysfunction?
Not usually on its own. In men with confirmed low testosterone it may modestly help erectile function, but PDE5 medicines remain the usual first treatment for ED.

How do daily low-dose tadalafil and as-needed ED medications compare?

How do sildenafil and tadalafil work?
Both are PDE5 inhibitors. They help relax blood vessels in the penis so an erection can happen with sexual stimulation. They do not cause an erection on their own.
Treatment and safety
How do testosterone injections, creams and pellets differ?
They differ in how often they are used, how steady the resulting levels are, how easily therapy can be adjusted or stopped, and in practical issues such as transfer risk with topical products. Topical products can transfer to others through skin-to-skin contact; approved gels carry a boxed warning about secondary exposure. Pellets cannot be adjusted quickly and require a minor procedure to place. All routes share the class risks and monitoring requirements of testosterone therapy. Compounded creams are not FDA-approved, and absorption cannot be assumed to match an approved gel. Availability and insurance coverage vary and may limit practical options. This page does not provide dosing or administration instructions.

How often will I need blood work once my testosterone dose is stabilized?
After initiating therapy, MMi will check your bloodwork around 9-12 weeks and then consider adjustments. Once your testosterone levels, hematocrit, and PSA are stable on therapy, blood work is typically performed every 6 to 12 months.

Treatment and safety
Is erectile dysfunction the same as low desire?
No. Erectile dysfunction is difficulty getting or keeping an erection; low desire is reduced interest in sex. They can happen together but have different causes and treatments.
Treatment and safety
Should I think about sperm banking before starting testosterone?
If you may want children later, ask about it before treatment starts. Because testosterone can reduce sperm production, some men choose to discuss banking or other options first.
Treatment and safety
What are the important risks and limits of testosterone therapy?
Testosterone therapy can raise red blood cell counts and blood pressure, suppress fertility, worsen sleep apnea in some men, and cause local or skin-related effects — and it is not a treatment for symptoms that have another cause.

What can cause erectile dysfunction?
Erectile dysfunction usually has more than one contributor — vascular disease, diabetes, blood pressure, medications, hormonal factors, neurologic conditions, sleep, alcohol, and psychological or relationship stress all play a role.

What did the TRAVERSE trial find about testosterone and heart risk?
In TRAVERSE, men with low testosterone and higher cardiovascular risk who received testosterone did not have more major heart events than those on placebo over the study period. Some other risks were higher.
Treatment and safety
What happens if I decide to stop testosterone replacement therapy?
Stopping TRT causes circulating testosterone to decline to pre-treatment levels or temporarily lower, often accompanied by a transient return of fatigue and low mood while natural production restarts. Many of the issues that brought patients to seek replacement will return.

What if the first ED medicine I try doesn't work?
That is common and worth reporting. Timing, food, dose adjustments by your clinician or switching medicines can help, and other options exist if pills are not enough.
Treatment and safety
What is gonadorelin and what is its role?
Gonadorelin is a form of gonadotropin-releasing hormone, the hypothalamic signal that prompts the pituitary to release LH and FSH. These hormones drive testicular testosterone production and sperm production. Gonadorelin is indicated for men seeking to maintain and preserve fertility, and to reduce testicular shrinkage—an uncommon side effect of TRT.

HCG is a hormone product with specific FDA-labeled uses, including prepubertal cryptorchidism, selected cases of hypogonadotropic hypogonadism in males, and ovulation induction in women. Its role for any individual man depends on diagnosis, fertility goals, labs and clinical judgment.

Why can't erectile dysfunction medicines be taken with nitrates?
