BACKGROUND: 17-Hydroxylase deficiency is the rarest form of congenital adrenal hyperplasia, a disorder that affects steroidogenesis, causing abnormal hormone levels. Studies have shown a clear association between 17-hydroxylase deficiency and primary infertility, but a definite protocol to treat the disorder has not been determined yet.
CASE PRESENTATION: Case I presents a 24-year-old Caucasian Israeli-Arab female who experienced 6 years of infertility. Before her initial visit to our clinic, she underwent three laparoscopic ovarian cystectomies, had an unsuccessful in vitro fertilization cycle, and was treated with combined oral contraceptives. Her hormonal profile was tested, and the results led to genetic counseling and the diagnosis of non-classical congenital adrenal hyperplasia. She was treated with estradiol, glucocorticoids, and transdermal testosterone. After hormonal levels were lowered, in vitro fertilization cycles were initiated, and the patient had a spontaneous ovulation. In case II, a 20-year-old Caucasian Israeli-Arab female presented for infertility evaluation owing to her oligomenorrhea. Her vitals and physical examination had normal results. The investigation of her abnormal hormonal profile led her to be referred to genetic testing, where the results showed the same genetic mutation as seen in case I.
CONCLUSION: Both cases highlight the distinctiveness of the condition, where an identical mutation in the gene responsible for the same enzyme can bring about diverse phenotypes. Case I offers a potential treatment protocol for this rare disorder.
