1) Oocyte collection with the technique of ultrasound guided transvaginal follicular content aspiration (Ovum Pick Up) in cattle and horse followed by in vitro embryo production with in vitro fertilization. After the successful adaptation of the technique we would like to offer/provide the procedure to farmers as a service.

2) Dog semen cryopreservation. We investigate the different factors (speed of cooling and thawing, cryoprotectants, etc.) that may have influence the outcome/result of dog semen freezing.

3) We have a research program studying the possibility of in vitro culture and cryopreservation of pre-antral follicles. The effect of the in vitro culture and supplementation of the culture medium with different chemicals/materials (e.g. PACAP), and cryopreservation in follicular development, in vitro ovulation and survival of the follicles are investigated.

4) The effect of PACAP (pituitary adenylate cyclase activating polipeptide) onto the reproduction is investigated. The aim of the research is also to study the cell-protective effect of PACAP in the different stages of reproduction (early embryo development, survival of frozen embryos, implantation etc.).

5) Importance of assisted reproductive techniques (ART) in sheep breeding. The aim of the investigations is to learn how the ART can be built into the sheep breeding technology applied in Hungary (estrous synchronization, artificial insemination, embryo transfer).

6) The use of ART in the protection of Hungarian native pig breeds.
