Abstract
An ovum collection device (20) includes a handle (4) and a collection needle (3) extending from the handle. The collection needle has a sharpened tip (44) for insertion into a follicle of an ovary. A collection duct (5) in fluid communication with the collection needle extends from the handle to a collection bottle (6). A heating arrangement (14) is used to maintain the collection needle at a selected temperature to prevent damage to an oocyte. The heating arrangement may be associated with a needle guide (72) on an ultrasonic probe such as a transvaginal ultrasonic probe (70).
