When can embryos be created from pregnant donors?

February 24, 2020

The general window for creating embryos from pregnant donors is 40 to 100 days of pregnancy. A large percentage of our IVF program is composed of pregnant donors that take advantage of this extended window for creating offspring. While the procedure is quite safe, clients should be aware that there is a slight risk of pregnancy loss from the manipulation of the reproductive organs.

What results can be expected with different semen types?

February 24, 2020

On a given sire, the development rate between conventional and reverse-sorted semen is generally very similar. However, we do see a significant decrease in development rate with pre-sexed frozen semen compared to reverse-sorted semen with many bulls. Thus, our recommendation for clients wanting to produce sexed embryos is to use reverse-sorted semen.

What results can be expected on each IVF cycle?

February 24, 2020

Results vary with each donor, but we typically expect to collect ~18 oocytes per aspiration. On average, 30% of these oocytes will develop into a viable embryo. Thus, we expect about 5 transferrable (Grade 1 & 2) embryos per IVF cycle on average. Donors that produce greater numbers of oocytes and oocytes of higher quality may see larger numbers of embryos produced, whereas donors with compromised reproductive conditions may have lower results. Development rate will also vary greatly depending on the sire used.

What results can be expected from reverse-sorted semen?

February 24, 2020

Based on fetal-sexing of pregnancies that result from reverse-sorted semen, we achieve greater than 95% accuracy of selecting for female calves (slightly less for male calves). Although most sires will sort accurately, the process can be affected by semen quality and concentration. There is often significant variation among sires in fertility and embryo development rates.
