The infertility of many cows could be treated by in vitro fertilisation. In the present study laparoscopy was utilised to recover the in vivo matured oocytes from the ovary of a standing donor. After the capacitation of fresh semen with high ionic strength medium and in vitro fertilisation, a rabbit oviduct was employed as an incubator for four to five days, in order to obtain sufficiently aged embryos to be transferred to the uterus of a recipient. Using surgical or non-surgical transfer six calves were obtained.
