Advanced Fertility & Endocrine in Encinitas operates from Suite C302 at 477 North El Camino Real, providing reproductive endocrinology and fertility services within the same medical complex that houses several North County specialty practices. The clinic focuses on hormonal evaluation and treatment for conditions affecting reproductive health, including polycystic ovary syndrome, thyroid-mediated ovulatory dysfunction, and endometriosis-related subfertility, collaborating with referring internists and family-practice physicians such as Elena Dolgonos, MD. Diagnostic workups include serial hormone panels, ovarian reserve testing via anti-Müllerian hormone and antral follicle count, hysterosalpingography, and semen analysis to identify male-factor contributions. The endocrine component of the practice also evaluates non-reproductive hormonal conditions, overlapping with the hormone-optimization services at Revive Med Spa – Encinitas. Highest-complexity cases involve controlled ovarian hyperstimulation protocols with gonadotropin titration guided by serial transvaginal ultrasonography and estradiol monitoring for patients preparing for in vitro fertilization transfer cycles.
