Hormones are powerful messengers that influence everything from mood and sleep to metabolism and cognitive performance. When hormone levels shift, whether from aging, stress, or underlying health conditions, the effects can be profound.
If you regularly struggle with fatigue, high stress, low libido, or uncontrollable weight gain, you may have a hormonal imbalance. At Avita MD, we provide personalized bioidentical hormone replacement therapy (BHRT). This process begins with a comprehensive health assessment and a detailed blood panel. Our team will review your results to evaluate your candidacy for BHRT, helping you restore your vitality and enhance your overall well-being.
Treatments tailored to you, including pellets, creams, gels, or injectables.
Every plan is built on advanced diagnostics such as DUTCH and blood hormone panels.
Pellet therapy is completed in minutes with lasting results for months.
Bioidentical hormones are plant-derived and match human hormones exactly.
Improved energy, mood, cognition, and sexual health with ongoing care.

Hormones play a crucial role in regulating numerous essential bodily functions, acting as a communication network among cells throughout the body. They influence various processes, including digestion, growth, appetite, immune response, mood, libido, physical strength, and cognitive function. Even minor hormonal imbalances can significantly affect overall health and well-being.
Bioidentical hormones are hormones that closely match those produced naturally by the body and can be infused for therapeutic purposes. In contrast, synthetic hormones, which differ in structure, may lead to undesirable side effects. The hormones utilized in bioidentical hormone replacement therapies are sourced from plants.
Hormone replacement therapies aim to restore balance within the body and alleviate symptoms that can disrupt daily life and personal relationships. The goal of Avita MD bioidentical hormone treatments is to focus on addressing various physical and mental issues, such as weight gain, fatigue, depression, and heart disease.
Unlike synthetic hormones, bioidentical hormones are plant-derived and are identical to human hormones. In turn, they are more effective and less likely to cause side effects like synthetic hormones. There is really no comparison.
Our precision approach begins with comprehensive testing. By looking beyond symptoms, we identify the exact hormonal imbalances driving your concerns.
Our data-driven approach ensures your therapy is personalized and effective.

Pellet therapy offers a steady, consistent release of bioidentical hormones. Tiny pellets are inserted just under the skin in a quick, in-office procedure, providing continuous hormone support for 3–4 months. This option avoids the ups and downs of pills or creams and is especially effective for testosterone replacement.
For patients preferring topical or oral absorption, compounded bioidentical hormones can be delivered as customized formulations.
In some cases, injectable hormones may be used to achieve optimal balance, particularly for testosterone replacement in men.

BHRT may be right for you if you’re experiencing:

Estrogen can also address vaginal dryness, itching, and discomfort during intercourse, giving you the power to reignite your flame.

For many women, BHRT can increase sex drive, ease mood changes, reduce irritability, and improve sleep.
After age 30, most men experience a gradual but continual drop in testosterone. That frequently leads to low energy, trouble concentrating, loss of muscle mass, weight gain, sleep disorders, high cholesterol, hypertension, depression, and declining sexual desire and performance. BHRT can be used to address these issues. For both women and men, clinical studies indicate BHRT increases the elasticity of blood vessels, allowing blood to flow more freely throughout the body. Bone density increases, and energy and alertness improve.
At Avita MD, Dr. Patricia Sitnitsky, MD, understands that while many individuals can benefit from bioidentical hormone pellets, not everyone is a suitable candidate. This determination is made following a comprehensive analysis. Before initiating bioidentical hormone therapy, Dr. Sitnitsky will conduct a thorough evaluation, including laboratory work and an EKG. For her female patients, she also requires that a PAP smear and mammogram be completed within the past year. Once it’s established that you are a good candidate for bioidentical hormone replacement, Dr. Sitnitsky will create and implement your personalized treatment plan.
