Abstract: A follicular growth inducing apparatus is suitable for a surgical procedure for inducing follicular growth and is less invasive and less likely to degrade the ovarian functions. The follicular growth inducing apparatus includes an ovarian puncture needle that forms a puncture hole by puncturing an ovary in a traveling direction of ultrasound emitted from a probe in a transvaginal ultrasound device toward the ovary, for inducing growth of follicles, and an optical fiber that guides a laser beam emitted from a laser generator. The ovarian puncture needle includes a needle tube including a basal end, a shaft supported on the basal end, and a needle tip continuous with the shaft. The needle tip punctures the ovary. The optical fiber is installable in the needle tube to have a distal end of the optical fiber adjacent to the needle tip.
