Aiyukai Nakano Ladies Clinic is a gynecology clinic located in Oji, Kita Ward, Tokyo. Since opening in 2000, the clinic has been involved in infertility treatment for over 20 years as a registered assisted reproductive technology facility, but since April 2022, the treatment system has been changed to focus on general infertility treatment up to artificial insemination. While striving for rapid elucidation of infertility causes, the clinic has established a system to refer patients requiring advanced assisted reproductive technology to specialized facilities at an early stage, and participates in subsidy programs for infertility testing. For male infertility, the clinic collaborates with Ebisu Tsuji Clinic; for in vitro fertilization, with Kato Ladies Clinic and Matsumoto Ladies Clinic; and for obstetrics, with Tokyo North Medical Center and other medical institutions. The clinic participates in the semi-open obstetrics system of Juntendo Hospital, and provides medical services including online eligibility verification, electronic prescription issuance, and generic drug prescribing. Preconception care testing and catch-up HPV vaccination are also offered, with 3D/4D ultrasound examinations available for Saturday afternoon prenatal checkups. With English-speaking services, credit card/electronic payment options, and barrier-free accessibility, the clinic continues to contribute to community healthcare.
