This is Gen 5 Fertility

There really is no other place quite like it.

It’s a place of peace. A place of hope. A place where the “impossible” becomes possible. It's a place where your dreams become our dreams. And together we work to make them happen.

It is a place directed by one of the leading fertility specialists in the world. It's a place offering a group of fertility procedures offered by no other center.

A place where every member of the staff is dedicated to you.

A place where the best equipment, the best protocols, the best staff come together to create something amazing.

Gen 5 Fertility is where so many babies have come from. And if we work together, it's quite likely where your baby will begin her or his precious life.

Because we believe that everyone should live a fertile life.


The Beginning

The day Gen 5 Fertility opened everything in the field of infertility changed. On that day, everything that had been done in the past was just that – in the past. Done. Tired.

On that day Generation 4 IVF became available in the United States. Generation 4 IVF not only gives couples with a poor prognosis a better chance to become pregnant, it dramatically increases the effectiveness and usefulness of IVF for those with a good prognosis.

Did the old ways sometimes work? Sure. Did parents get the babies they wanted? Sometimes. Did all of the intended parents that wanted to have a baby get the chance that they deserved? Unfortunately not.

The Gen 5 Fertility Center’s focus in solely on one goal: Making sure that every patient, no matter the reason for their infertility, has the greatest possible chance to succeed.

The new Generations of IVF are a whole new way of looking at infertility and IVF. It's a new way of looking at why patients choose to do IVF and what they want to achieve as a result of doing IVF. It provides new ideas about the causes of "infertility" and about how to treat them.

With Generations 4 and 5 IVF, everything changes.

By the way, did all this really start in 2018? No. It's beginnings can be traced to a time over 25 years ago when what is now called Preimplantation Genetic Diagnosis (PGD) first became clinically useful. Initially, the results were available only for a few rare disorders that were found virtually always in males. Over time, PGD became useful for many disorders involving single genes (like sickle cell disease).

Eventually, what was (and for some, still is) called Preimplantation Genetic Screening (PGS, now PGT-A) began. It started by looking at a few and then all chromosomes. It was designed to answer the question: does this embryo (fertilized egg) have the correct number of chromosomes to lead to a healthy baby? Down Syndrome is an example of a situation when the chromosome number is wrong in which there are three rather than two copies, one from each genetic parent, of chromosome 21. The technologies we use to test whether an embryo is genetically normal are now much more accurate and comprehensive. At present, Next Generation Sequencing (NGS) using laser biopsied blastocysts is considered the state-of-the art way to answer questions such as these.

These techniques are considered Generation 3 of IVF. Unfortunately, many fertility centers around the world either legally can't or have chosen not to offer even this generation of IVF.

As time passes, we will give you more details about the present state of IVF and what we are doing to begin the long needed advance into Generation 5 IVF.


The Gen 5 Fertility Difference

We started Gen 5 Fertility because we wanted to fix all the problems we had seen in fertility care over many years. All the things that make the fertility process more difficult than it should be. All the things that reduce a patient's chance of becoming pregnant. The goal of the clinical and laboratory team at the Gyn 5 Fertility Center is simple: Treat each client the way they deserve to be treated, treat each client the way that we as experts in fertility would want to be treated.



Each patient is different. Each patient deserves care designed specifically for them. That is the only way you can do the best you can do. Our protocols are unique to each patient and change throughout the treatment cycle according to ever changing hormonal, ultrasound and other information. At no point are patients placed on a "standard protocol." At no point are patients told that their retrieval will be done on a given day. Each woman has her own way of responding. We listen. That's the way is should be.


Led by two of the leading fertility specialists in the world, Samuel Wood, M.D., Ph.D. and Benito Villanueva, M.D., the care patients receive involves the most advanced procedures and protocols available anywhere. Gen 5 Fertility's protocols are unique. Although the physicians at Gyn 5 Fertility have trained many in their techniques over the years, they continue to evolve and so only patients at Gen 5 Fertility receive the finest in care. The ultrasound monitoring of all patients is performed only by a fertility specialist. Never by an "assistant." Never. The reason non-physicians are used by far too many fertility centers is to increase their profits. That’s sad. Our primary goal is the patient not money. Never will we allow anyone except a trained physician perform ultrasounds for our IVF patients. Never.

All eligible patients are given the chance to select Generation 4 (and soon, Generation 5) procedures, and all patients receive the cumulative benefit of the knowledge that arises from the experience of treating thousands of patients over a quarter of a century. Gen 5 Fertility also maintains an ever expanding range of research endeavors. Among these is research into the potential rejuvenating effects of a groundbreaking new procedure that involves the infusion of platelet-rich plasma (PRP) into the ovaries. Dr. Villanueva was responsible for the first successful IVF in San Diego years ago. He brings his long experience and wide knowledge to every patient he sees.

There is no doubt in our minds that our clinical and laboratory staff are the best anywhere. Each staff member was painstakingly selected based on their intelligence, knowledge and their ability to care for their patients. Not only are they now highly experienced and competent, they share our dream of provided low-stress care so that patients can fully understand everything and are able to reach their full fertility potential. They understand and are available to their patients whenever their patients need them. All staff understand fertility deeply and have been trained specifically by Dr. Wood and Dr. Villanueva to insure they are not negatively affected by any suboptimal treatment protocols they may have learned in the past. Working with one of these outstanding professionals will not only reduce your stress, it will do the most important thing: increase your chance of success.

An important note about Directions to our Center. Even though we are easy to see from Interstate 5, we can be a little tricky to find the first time you visit us because the exit you need to take to get to our office is off of the I-5 Bypass not the I-5.

From the North: Take I-5 South. Take the I-5 Bypass just beyond the Carmel Valley Road exit and continue to the Carmel Mountain Road exit. Take a right on Carmel Mountain Road and then take the very first right into a drive that is marked “The Reserve.” Continue to the top of the hill and you’ll see our sign.

From the South: Take I-5 North. Take the I-5 Bypass just beyond the Sorrento Valley Road exit and continue to the Carmel Mountain Road exit.

Can You Become a Patient Now?

Yes! When we fist started Gen 5 Fertility, we limited the number of patients that we saw because we wanted to make sure that all of the patients that had waited became pregnant first. They had waited a very long time for the type of care we provide, care they believe they could receive no where else. We are pleased that virtually all of them have become pregnant, and now we are opening our Center to all fertility patients.

Although we would love to see each of you at our Center, we would also be happy to receive a note from you or to do a WeChat or Skype call with you. You can send us a message using the form to the right and you can contact us to arrange a video call.

Now all patients will be able to become part of the Gen 5 Fertility family. We hope to see you soon. Do not give up hope!

Our Outstanding Staff

Our staff is unique. Each of them is exceptional. Each of them is highly experienced. Each has worked with at least one other fertility center. But each knew things could be done better, so much better. And each had many ideas about how to make things better. Each has the freedom to explore their ideas. Each is valued as they should be. Each has the knowledge required to make each client's journey easier, less stressful and more successful.

Apart from these things, why are they unique? Because in each case, they left another fertility center and came to us asking if they could become a part of what they believe will soon be known as the finest, most advanced fertility center in the world. Below we will introduce you to the Medical Director, the Director of Research, and the Laboratory Director aof Gen 5 Fertility. If we work together with you in the future, you will meet the other outstanding members of our staff.



Samuel Wood, m.d, ph.d., m.a.,m.b.a., hclD/CC(AAB), FACOG

Dr. Wood is a one of the leading fertility specialists in the world. He has helped patients from all continents (except Antartica) have the babies they desired.

As can be seen below, it is highly unlikely that any other fertility specialist in the world can match his array of credentials. 

Dr. Wood is a board-certified Reproductive Endocrinologist and world-renowned fertility specialist as well as an expert in reproductive genetics with over 25 years of clinical experience. Dr. Wood is the only fertility specialist in the U.S. who has the honor of being a longtime listee in three Marquis’ publications: “Who’s Who in America,” “Who’s Who in the World,” and “Who’s Who in Science & Technology.” His clinical skills have won him many accolades including being named a "Top Doctor" by U.S. News and World Report, a "Super Doctor" by and has earned ratings of "Superb" (9.8) by the Avvo physician rating service and 4 out 4 stars on the patient-based rating site He was named one of the “50 People to Watch” by San Diego Magazine and one of the 20 "Men who Impact San Diego" by San Diego Metropolitan Magazine. He is also a past member of the Board of Directors of the San Diego County Medical Society.

Dr. Wood’s distinguished academic background also includes an M.A. in Psychology, a Ph.D. in Biochemistry and Molecular Biophysics, as well as an M.B.A. After a residency in Obstetrics and Gynecology at the University of North Carolina, he completed a fellowship in Reproductive Endocrinology and Infertility at UCSD and is Board Certified in both Obstetrics and Gynecology and Reproductive Endocrinology and Infertility achieving both in the quickest possible time. He has also earned the honor of being a certified High Complexity Laboratory Director (HCLD) by the American Board of Bioanalysts (AAB) in two separate areas. He has published numerous scientific papers in multiple areas of study. His academic credentials are not surprising given that he is also a longtime member of Mensa, the society for individuals with a documented high IQ.

Dr. Wood also has extensive media experience having been featured on numerous local and national print, radio and television news pieces including the “New York Times,” “Newsweek,” “Vogue,” “Cosmopolitan,” “Dr. Oz,” “The Doctors,” “World News Tonight,” “NBC Nightly News,” “Good Morning America,” “The Today Show,” “ABC’s World News Tonight,” PBS’ “Frontline,” and a BBC documentary seen worldwide, as well as all major television outlets in San Diego and many others across the country. Over the past few years, he has appeared on over 100 local and national radio, television and print shows. He is frequently featured on local and national morning television segments, which provides insights into the latest research in reproductive endocrinology/infertility, stem cell research, behavioral endocrinology, reproductive genetics and medical ethics.

Despite these many accomplishments, perhaps what is most exceptional about Dr. Wood is his gentle, caring nature. He is known by his many patients from around the world for providing each patient with highly personalized care. He especially specializes in the fine details of protocols for Chinese patients, whose responses are in many cases significantly different than those of American and European patients. There is perhaps no fertility specialist in the world who knows more about the optimal ways to treat Asian patients.

His current positions include being President and Medical Director of Gen 5 Fertility in San Diego, Laboratory Director of Progenesis, a leading PGS/PGD company, and CEO of Stemagen, a stem cell company renowned for having been the first research facility to therapeutically clone adult human cells.
