The Johns Hopkins Division of Reproductive Endocrinology and Infertility (REI) is dedicated to providing comprehensive and innovative care for individuals facing infertility. Patients benefit from access to nationally and internationally renowned fertility specialists who employ the latest testing and treatment options. Led by Valerie Baker, M.D., the division also offers fertility preservation services and participation in cutting-edge clinical trials, ensuring that patients receive the most advanced care available.

The establishment of the Johns Hopkins Fertility Center represents a pivotal moment in the evolution of reproductive medicine at Johns Hopkins. Seamlessly integrating academic excellence with patient-focused care, the center translates decades of REI research, innovation and clinical expertise into a dedicated space designed to support patients at every stage of their fertility journey — including individuals who have experienced treatment failures at other centers.

In addition to addressing infertility, the REI division provides specialized care for recurrent pregnancy loss and reproductive endocrine disorders, including absent or irregular menses, premature ovarian insufficiency and polycystic ovary syndrome.

Clinical Initiatives

New Green Spring Station Facility

In 2023, the Johns Hopkins Fertility Center expanded its capabilities with the opening of a state-of-the-art facility at Green Spring Station in Lutherville, Maryland. Designed to enhance patient experience, care coordination and treatment efficiency, the center features:

• 17,000 square feet of clinic space
• In vitro fertilization (IVF) laboratory
• Dedicated surgery center
• Andrology laboratory for sperm testing
• Endocrinology laboratory for hormone analysis

In a single location, patients can access consultations, saline infusion sonograms, blood hormone level tests, hysteroscopies, intrauterine inseminations and IVF procedures.

Specialized Patient Care

For patients with complex health issues who cannot have oocyte retrieval in an outpatient setting, the team can perform egg retrievals at The Johns Hopkins Hospital with safe transport of eggs to the IVF laboratory. Telemedicine consultations are available to better serve people without requiring travel to Lutherville.

Services Offered

The division provides a wide range of services, including:

• Ovulation induction
• Intrauterine insemination (IUI)
• IVF and preimplantation genetic testing
• Oocyte and sperm donation
• Gestational carrier services
• Fertility preservation (cryopreservation of oocytes, embryos and ovarian tissue)

Our specialists work with experts in related conditions, such as fibroids, endometriosis, high-risk pregnancies, cancer and sickle cell disease, to ensure that patients receive multidisciplinary care tailored to their needs.

Research Initiatives

Johns Hopkins Fertility Center Research

Research in the Johns Hopkins REI division has focused on perimenopause and menopause and risks for hot flashes, fertility preservation and assisted reproductive technologies. Additional research focused on hormonal contraception, prolactin disorders and polycystic ovarian syndrome.

Several REI faculty members are leading National Institutes of Health (NIH)-funded clinical trials to improve the success and safety of IVF and to investigate novel treatments to improve the fertility of individuals with conditions such as uterine fibroids or endometriosis. Funding from the Jones Foundation is supporting national studies led by REI faculty examining the health of children conceived following specific techniques used during IVF to optimize safety. Other NIH-funded studies led by REI faculty members are examining the effect of uterine fibroids on long-term cardiovascular health.
