At Reproductive Partners San Diego (RPSD), our team of fertility specialists in San Diego includes highly trained reproductive endocrinologists who guide individuals and couples through every stage of their fertility treatment journey. Here’s what you need to know.

What Does a Reproductive Endocrinologist Do?

A reproductive endocrinologist (RE) is a physician who specializes in the complex hormonal systems that control reproduction. After completing medical school and a residency in obstetrics and gynecology (OB/GYN), reproductive endocrinologists undergo additional fellowship training focused on infertility, hormone-related conditions, and advanced fertility treatments.

They are experts in diagnosing and treating:
  • Female infertility (e.g., ovulation disorders, diminished ovarian reserve, endometriosis, PCOS)
  • Male infertility (e.g., low sperm count, sperm motility issues, hormonal imbalances)
  • Recurrent miscarriage
  • Fertility preservation (e.g., egg and sperm freezing)
  • LGBTQ+ family building needs
  • Hormonal conditions affecting reproduction

Whether you’re just beginning to explore your fertility or need a more advanced approach like IVF in San Diego, a reproductive endocrinologist is your go-to expert.
