The WFI Laboratory

Find Cutting-Edge Technology at Our Fertility Center in Los Angeles

Science holds the key to addressing cases of infertility. Technology helped pioneer treatments such as in vitro fertilization and artificial insemination, and a state-of-the-art laboratory can be the difference between success and failure in your journey to conception. You want to choose the California fertility clinic with the most up-to-date tools to maximize your chances of getting pregnant or getting a surrogate pregnant.

The better the technology your clinic uses, the better your shot at achieving your dream. Western Fertility Institute knows this, and that’s why we employ the most advanced techniques with our patients based on the most current research and theories. Does this approach work? Yes, it does — the proof is in our outstanding, higher-than-industry-standard success rates.

What Treatment Options Does Your Encino Fertility Clinic Handle?

We provide a range of third-party reproductive treatment options for couples and individuals trying to conceive, including:

  • Artificial insemination: Donor sperm is used to fertilize an egg.
  • In vitro fertilization and frozen egg transfer: We can fertilize an egg or donor egg with sperm or donor sperm outside of the uterus, then implant the fertilized egg in the uterus of the intended mother or surrogate. We can also freeze embryos for future use. We have a FET Cycle success rate of over 80 percent.
  • Surrogacy: A surrogate carries a fertilized egg to term for a couple. It may be the product of their own egg and sperm or some combination of donor eggs and sperm. We have a surrogacy success rate of above 80 percent.

Why Are We the Best California Fertility Clinic?

We are the best because we get the best results, and we hold your hand while we do it. Our lab is not cold or impersonal. We get to know our patients, donors and surrogates, and we treat them as real people. This is the difference between our clinic and many others you may find around the state.

While we rely on technology, and it’s a huge part of our success, we also recognize that ultimately, fertility treatment is about human connection and the desire to have a child. You cannot measure these emotional aspects in the lab, and we put the highest priority on them throughout the process.

What is Sex Selection?

It is common for many patients to be curious about the ability to choose the sex of their baby. This is known as Sex Selection (also commonly referred to as Gender Selection). Through genetic testing, this is possible for our patients undergoing IVF at Western Fertility Institute. A  By-product of the genetic testing performed on the embryos called PGT-A allows for differentiation between male and female embryos since the sex of each embryo is identifiable by their chromosomes.


How does Sex Selection Work?

Sex selection through Preimplantation Genetic Testing for Aneuploidy (PGT_A) testing allows patients to select the sex of their embryos with almost 100% accuracy. Our highly skilled embryologists will biopsy a single cell from the embryo and send it to a third-party laboratory for PGT-A testing. The PGT-A results will show if each embryo has the proper number of chromosomes as well as the prospective of sex. Embryos containing two X chromosomes are female, while male embryos will contain one X and one Y chromosome. This allows the patient to choose a PGT-A embryo of a desired sex for transfer.


Why Do People Use Sex Selection?

Patients choose to use sex selection as an option for multiple reasons.  In some cases, it can be used for medical reasons.  Sex selection allows for the prevention of sex-linked genetic diseases and chromosomal disorders. For instance, there are certain disorders, linked to the X or Y chromosomes, that have the potential to be passed on to only a son or only a daughter. In other cases, sex selection can be used for what is known as "family balancing". Family balancing is when the patient chooses a specific sex in order to fulfill their desire of a balanced family.  This can include choosing a sex based on a previously lost child, because they feel better equipped to raise a specific sex, or they want representation of both sexes in their family.
