RESUMEN
OBJECTIVE: To present a successful IVF frozen-embryo replacement cycle in a 44-year-old woman, using her own oocytes. DESIGN: Case report. SETTING: Assisted reproduction unit in a university hospital. PATIENT(S): A 44-year-old woman underwent IVF frozen-embryo replacement cycle after three unsuccessful IVF fresh cycles with her own oocytes. The couple were unable to achieve pregnancy for 4 years and were advised to have IVF because of the long duration of subfertility and woman's age. INTERVENTION(S): In vitro fertilization. MAIN OUTCOME MEASURE(S): Pregnancy, live birth, baseline FSH on day 3, and IVF outcome. RESULT(S): The woman achieved pregnancy through a frozen-embryo replacement cycle and gave birth to a healthy girl who weighed 3,330 g. CONCLUSION(S): Pregnancy is difficult to achieve for women >40 years of age and especially so for a woman at the age of 44 years. In vitro fertilization cycles may not lead to the desired result, but the availability of a frozen embryo replacement cycle is associated with better prognosis.
