What If I Use Two Sperm Sources?

How Does Using Two Sperm Sources Work?

Dr. Mark Leondires, Reproductive Medicine Associates of Connecticut discusses the common questions surrounding using two sperm sources during surrogacy and what options are available.

Is it common to use two sperm sources?

It is very common. In fact, the majority of the couples that I see, do want to move forward with two sperm sources with the goal of having two kids at least, from both of their biologies and that would mean that the children are half-siblings and there's one donor shared in between them. So taking that into account then we have to consider how you navigate that as a family to be.

How does this change the IVF process?

So first things first, you know you may understand that the IVF process involves using an egg donor and then fertilizing those donated eggs with your sperm. But, you might not be aware of the natural attrition rate from eggs retrieved to high-grade embryos to chromosomally normal embryos, since embryos that actually make pregnancies and babies. With that being said if you're a dad-to-be couple, you really need a lot of eggs. This means we're going to help you find an egg donor who has a high potential to giving us at least 15 if not 20 to 30 eggs. That will help us navigate the natural attrition rate that we see in the lab.

Does this impact the choosing & screening process?

The truth is that not every egg donor has the potential to give us that many eggs. So the screening process is a little bit more in-depth. You might find an egg donor that you really like and want to move forward with and it's going to be the clinic's responsibility to evaluate her ovaries through a process called a transvaginal ultrasound to look at her base antral follicle count to see how many resting follicles that we see. Which is a predictive value of how many eggs we can get and also to get a hormone level called anti-mullerian hormone. We like that hormone level to actually be greater than 4 as a predictive value that we can get more than 15 eggs maybe 20-30. As we look at first-time donors we're going to use that metric. But, we may also look at previous donors who have a proven outcome or a proven egg yield. We might have more confidence in recommending this type of donor for you because she has proven performance.
