Abstract

A short-type aspirator of follicular fluid was developed for collecting simultaneously follicular fluid and granulosa cells from mature follicules of live estrous cows.
It was designed so as to provide the following advantages.(1) It can be handled without an assistant.(2) It can be operated with one hand by making length minimal (135mm) and thus needle point movement least.(3) The volume of the internal syringe is about 2ml, thus making it possible to completely aspirate the mature follicular fluid.(4) The syringe needle is 1.2×34mm and does not bend easily when puncturing a follicle through the vaginal wall. It may be used not only for the aspiration of folliclar fluid but also for direct drug injection into the ovarian parencyma and follicular cysts.
