Our goal is to correct the hormonal imbalance, reduce breast tissue growth, and restore normal chest contour safely under medical supervision.
Gynaecomastia is the enlargement of male breast tissue caused by a hormonal imbalance between testosterone and oestrogen. It can occur naturally, after anabolic steroid use, or as a side effect of certain medications.
The most common causes include anabolic steroid use, testosterone therapy without proper monitoring, obesity, liver issues, or medication such as antidepressants or anti-ulcer drugs. Elevated oestrogen or suppressed testosterone often leads to glandular tissue growth under the nipples.
In mild cases related to puberty or short-term hormone changes, it may resolve naturally. However, persistent or steroid-induced gynaecomastia usually requires medical treatment to correct hormonal imbalance and reduce tissue growth.
Treatment focuses on balancing hormones and reducing glandular tissue. Options include prescription medication such as selective oestrogen receptor modulators (SERMs) or aromatase inhibitors. Post Cycle Therapy (PCT) may also be prescribed after anabolic steroid use.
Harley Street MD specialises in medical (non-surgical) management. If the glandular tissue does not respond to medication, your doctor may refer you to a trusted surgical partner for liposuction or excision.

Most patients notice improvement within 4–8 weeks of starting therapy. In long-standing cases, results may take several months as hormone levels stabilise.
Once hormonal balance is restored and glandular tissue reduced, results are generally long-term. However, recurrence may occur if anabolic steroid or testosterone misuse continues.
