You want to create a family, and the thought of having a biological connection to your child is important to you both. As two hopeful dads navigating the in vitro fertilization (IVF) process, it's natural to wonder if you can mix sperm for IVF, giving both of you the chance to feel that bond. While mixing sperm for surrogacy and IVF may not be possible in the way you think, split-cycle IVF enables you both to be involved in the embryo creation. We understand how important it is for both partners to feel included in this journey, and we're here to walk you through what’s possible with IVF and how you can grow your family together. If you have questions about surrogacy or the embryo transfer process, don't hesitate to reach out for more information or call 1-800-875-BABY to speak with a surrogacy specialist.
Can You Mix Sperm for a Surrogate With IVF?
No, mixing sperm for surrogacy is currently not possible. Clinic guidelines and federal laws require that the sperm provider’s identity be known to establish legal parentage. While you might want to “randomize” whose sperm is used, each sample must be kept separate.
When you use your sperm, you'll need to sign consent forms and work with a reproductive attorney to establish parental rights. This is a legal safeguard to ensure clarity for all parties involved, including you, your partner, your surrogate and your future child.
Currently, mixing sperm from two different sources to fertilize a single egg is not possible. In IVF, only one sperm can fertilize an egg to create an embryo. However, research into primordial germ cells shows potential for creating functional sperm and eggs in the future. While this might one day allow for combining genetic material from two individuals, the concept is still in its early stages. For now, the only option is to keep the sperm samples separate.Can You Mix Sperm Together to Fertilize One Egg?
Split Cycle IVF for Gay Couples
While you and your partner can’t mix sperm for a randomized outcome or to create an embryo with both of your DNA, each half of the eggs can be fertilized with one partner’s sperm through what is known as split-cycle IVF.
Typically, the division of eggs is done as evenly as possible. If there are an odd number of eggs, the clinic will ask you both to decide whose sperm will be used for the remaining egg.
While the sperm samples remain separate, split-cycle IVF process offers a balanced way to give each partner an equal chance at creating embryos and potentially sharing a genetic connection with their child. This way, you both get to be involved in the journey, even if your sperm samples can’t be combined.
Once the embryos are created, the next step is choosing which one to transfer to the surrogate. In split-cycle IVF, most clinics will recommend transferring the best-quality embryo, regardless of whose sperm was used. Embryos are typically graded based on their development at days three or five. Typically, embryologists use grading scales to indicate an embryo’s progress and likelihood of success. An embryo with a higher grade may have a better chance of resulting in a healthy pregnancy, so doctors generally prioritize this over genetic considerations.How Do You Decide Which Embryo to Transfer?
Can You Transfer Two Embryos at Once?
Yes, you can transfer two embryos at once, but this comes with the risk of a twin pregnancy. Having twins can sound exciting, but it also increases the health risks for both the surrogate and the babies. Many surrogacy professionals advise against intentionally trying for twins because carrying multiples can lead to complications.
For this reason, it's often safer to transfer one embryo at a time. If you and your partner are set on transferring two embryos, you may need to wait longer to find a surrogate who is comfortable with potentially carrying twins. Not all surrogates are willing to take on that additional risk.
We understand how exciting it is for both of you as you look forward to becoming dads. Once your embryos are created, the next step is to match with a surrogate. Our average wait time for a match is typically one to six months. During this time, you can work with our agency to create your intended parent profile and fill out your surrogacy planning questionnaire. If you don't have embryos yet, that's okay. You can still get started! We can guide you through your first steps and help you find a reputable fertility clinic.
