Where is our IVF lab located?
Our IVF Laboratory is located in our main office in Greenbrae, Marin County, California.
What hormone tests do I need as part of an infertility evaluation?
Helping to characterize ovarian reserve through bloodwork is the single most time-sensitive test to pursue when struggling to conceive. Most often this consists of measuring anti-müllerian hormone (AMH) but sometimes a basal follicle stimulating hormone (FSH) level can provide additional insight (ultrasound can also be informative). Besides ovarian reserve testing, endocrine (hormone) problems that can interfere with fertility include PCOS (elevated androgens), underactive (or overactive) thyroid function and inappropriately elevated prolactin (the hormone responsible for breast milk production which can be raised outside of pregnancy). These tests are traditionally ordered as indicated.
What information does a semen analysis provide?
The main parameters that are examined during a semen analysis include the volume, concentration, motility and morphology (shapes) of sperm. These numbers are then used to formulate the clinically-significant parameter called the total motile count which is the quantification of “how many moving sperm are in the ejaculate” (normally only a percentage of sperm are moving). Even more insight can be gained in measuring how many sperm are progressively motile (physically propelling forward vs swimming in place). Reference ranges for a semen analysis are based upon men from around the world who have successfully sired a child. It is important to understand that a single semen analysis does not necessarily provide the complete picture about fertility potential. Semen quality can fluctuate from day to day and the main parameters listed above do not fully represent the true potential of sperm to fulfill their required contribution to healthy embryo creation.
Can my partner do double collections for IUIs?
Yes, your partner can do double collections for intrauterine inseminations (IUIs). Double collection refers to collecting two semen samples, typically within a short time frame, to potentially increase the number of motile sperm available for the IUI procedure. Issues to consider in this strategy are fluctuations in output (the quantity of the second sample can sometimes be lower or it can sometimes be higher!), timing,logistics and patient experience (the process can be physically and emotionally demanding).
How do you process sperm for use with IUI or IVF?
We are proud to offer the
Zymot device for sperm processing, a novel approach that promotes the selection of sperm with the highest capacity for healthy embryo creation.
What fertilization techniques do you use, ICSI or conventional insemination?
ICSI (intracytoplasmic sperm injection) is a laboratory procedure where a single sperm cell is chosen from the provided semen sample and injected directly into one egg cell under a microscope. Conventional insemination is a laboratory procedure where an egg is exposed to a significant quantity of sperm (~100,000) with the goal of a single sperm successfully fertilizing the egg through its own effort. Both methods most often produce equally good outcomes but for some individuals and couples there may be a method that is most optimal (most successful) for them. As in all of our operations at MFC, we individualize treatment recommendations. Factors to consider include current and past semen analysis indicators, past proven fertility, general statistical probabilities, theoretical associated risks and patient values.
What kind of embryo culture system do you use?
We are so proud of our embryo culture system which employs the latest technology and principles to create the best possible embryos for you. Our advanced
incubators (called “Geri’s”) allow culture to proceed with zero exposure to the external environment for the whole duration of their development (~ 1 week). As an individual embryo has its own developmental trajectory, timelapse technology (a picture of the individual embryos is taken every 5 minutes) allows us to pick the optimal timing for interventions (such as embryo biopsy or embryo freezing). Each patient gets their own individual chamber and our beloved Geri’s also provide humidity which allows us to avoid compensatory interventions that are necessary with “dry” incubators.
In addition to helping me to become pregnant, what else can I learn from going through IVF?
Going through the laboratory phase of IVF can provide a deeper level of understanding than you can ever achieve from any pre-IVF tests. Metrics you will acquire include egg yield (do my individual follicles yield eggs at the expected 1:1 ratio?), egg maturation rate (do the eggs that are collected match the maturity stage that was predicted by ultrasound?), fertilization rates (do my eggs and sperm come together at the expected rate of 80-85% of the time?), embryo development rates (do 50% of my early stage embryos develop into advanced stage blastocysts?) and euploidy rates (does my cohort of embryos match the predicted rate of euploidy based upon my age?). Any deviations from averages may provide subtle clues that can inform use of your true reproductive potential.
Should I choose preimplantation genetic testing for aneuploidy (PGT-A) as part of my IVF lab plan?
PGT-A is a laboratory test that provides information about whole chromosomes (large pieces of DNA) in individual embryos. Abnormal chromosome copy numbers (there should be two and only two copies of each of the 23 chromosomes in a human cell) are a major contributor to impaired reproductive capability and the incidence of abnormal chromosome content is strongly related to age. The goal of PGT-A is to “screen out” embryos with chromosome problems. In practice, current clinical research supports the use of this technology (especially in patients of advanced reproductive age) however it is important to understand testing limitations. From a scientific perspective the testing methods are extremely complex and validity and reproducibility capabilities are continuously evolving. For example, our field’s current best estimates regarding false positive or false negative results is somewhere around 2-4%. Ultimately the use of PGT-A by patients is an individual choice made after careful consideration, ranking values such as cost, past reproductive experiences (going through a miscarriage), general reproductive viewpoints and long term family building goals.
What other genetic technologies do you offer besides PGT-A?
We work with an array of genetics reference labs to provide you with a platform that best fits your reproductive goals. Several labs offer parental verification, confirming the parental origins of the embryo. PGT-P tests embryos for disease risk for medical conditions that might be a part of your family history (diabetes, asthma, cancer, mental health). The latest form of genetic testing, whole genome sequencing (WGS), holds the promise of detecting de novo (new) conditions that arise spontaneously during egg, sperm or embryo development.

What is your policy on working with abnormally fertilized eggs?
There is an increasing recognition in our field that a proportion of embryos once thought to have no potential (based on their fertilization appearance) can actually lead to a normal liveborn baby. In line with our “nothing left behind” policy, all fertilizations with initial abnormal appearance are kept in culture and watched for development along with all of the other embryos. Many times abnormal fertilizations do not result in a fully developed embryo. However, if one does make it to full development, our lab will freeze and store it along with your other embryos.
How do you ensure no mix ups in the lab?
At MFC, safety is our priority. Our clinic staff and embryologists are constantly performing redundant name checks, verifications, cross-checking paperwork, lab orders, and information in the patient’s chart. Our lab workstations only house one patient sample at a time and our moderate lab volume mitigates against errors associated with high throughput.
How long can embryos be frozen?
Embryos can be stored indefinitely once they are frozen. Current studies and practice indicate that embryos can remain viable for decades after freezing. No “expiration” point has yet to be identified.
What makes your lab different?
In our lab, our laboratory director, Dr. Uzelac, holds his High-complexity Clinical Laboratory Director (HCLD) license is onsite and able to advise whenever needed, unlike many labs where the lab director does not often work onsite and can even live out-of-state, only coming by their lab for routine check-ins. Both of our embryologists hold technical supervisor (TS) licensure, and have many years of experience in the field.
Is the lab accredited by any professional bodies?
Yes, our laboratory is accredited by the College of American Pathologists (CAP), which is the gold standard for IVF laboratories across the country. We also hold all current state and federal licenses (California Tissue Bank, CMS, CLIA) required to operate.
What certifications and experience do your embryologists have?
Our embryologists hold college degrees in scientific fields, as well as certification by the American Board of Bioanalysis and American Association of Bioanalysts as Technical Supervisors (TS). Both are considered “senior” in the field and have been working together for 10 years. This elevated background and seamless team translates into better outcomes for you.
