What is OPU?

In OPU, immature oocytes are aspirated from the ovaries using a transvaginal probe, and subsequently located and evaluated for quality.

OPU/IVP

Since September 2012, Hurkmans ET offers the OPU/IVP technique. This technique is an alternative to superovulation, and its advantages include:

Procedure
OPU (Ovum Pick-up): In OPU, immature oocytes are aspirated from the ovaries using a transvaginal probe, and subsequently located and evaluated for quality. IVP (In Vitro Production): The retrieved oocytes are matured overnight in an incubator. After maturation, fertilization takes place and the fertilized eggs are cultured for a week in the incubator. After seven days, the produced embryos can be transplanted fresh. Or if desired, they can be frozen and thawed to be transplanted at a later time. The result of this technique is highly dependent on the donor cow and bull, and can range from 1-4 embryos per session (week).

In addition to OPU/IVP, we offer the option of Cull-cow/IVP for slaughter cows.

Advantages of cull-cow IVP:

Procedure
Cull-Cow/IVP: With Cull-cow IVP, the ovaries of cull cows are delivered to our laboratory. We collect the usable oocytes out of them. These are then fertilized and placed in culture, and after one week the produced embryos can be transferred or frozen. The result of Cull-cow/IVP varies depending on the number and quality of the oocytes and the sperm used between 0-28 in the past 9 months. (Average of 10 embryos per cull-cow.)
