Low testosterone, diagnosed before it's treated.
A low number is a signal, not a diagnosis. Dr. Hasan finds the cause, protects your fertility, and monitors therapy safely, in Wexford or by secure video.
One symptom is easy to dismiss. Several tell a story.
One low number. Many possible reasons.
The cause decides the treatment. Sometimes fixing it restores testosterone without lifelong therapy. Sometimes it reveals a problem that needs attention on its own, such as a pituitary tumor.
Dr. Hasan is a former co-director of a pituitary clinic in Pittsburgh. When the labs point to the pituitary gland, the evaluation goes straight to the right tests, including MRI when needed.
Weight & insulin resistance
Lowers testosterone, and low testosterone makes weight harder to lose.
Sleep apnea
Common, often missed, and treatable.
Medications
Opioids, steroids, and some others suppress production.
High prolactin
A pituitary hormone that shuts testosterone down.
Pituitary problems
The gland that signals the testes to make testosterone.
Testicular causes
Injury, genetics such as Klinefelter syndrome, or past treatment.
Timing matters as much as the number.
Early-morning tests, repeated
Testosterone peaks in the morning and varies day to day. Diagnosis needs two properly timed morning blood tests, not one random result.
Read with the right partners
LH, FSH, and prolactin show whether the problem starts in the testes or the pituitary. Free testosterone is checked when binding proteins are abnormal.
A clear answer first
You know why it's low, and whether treatment will help, before anything is prescribed.
The right treatment depends on the cause and your plans.
Testosterone therapy
Injections, gels, or oral capsules, dosed to your labs and adjusted over time. Restores energy, libido, and mood when low testosterone is confirmed.
Fertility-sparing therapy
Standard testosterone can lower sperm production. Medicines such as clomiphene or hCG raise your own testosterone instead. This is discussed before you start, not after.
Treat what's driving it
Weight loss, sleep apnea treatment, or a medication change can raise levels on their own. See medical weight loss.
What we check once you're on testosterone
Labs are checked a few months after starting, then at least yearly, following Endocrine Society guidance.

Many men start testosterone from a single lab result. Dr. Hasan reviews whether therapy was needed, checks your dose, red blood cell count, and fertility plans, and then fine-tunes treatment or helps you come off it safely.
