Many of us have heard of oocyte cryopreservation (egg cell freezing) because of how popular it's become among famous personalities in recent years. Sofia Vergara from the hit TV show Modern Family, pop singer Rita Ora and Celine Dion have all undergone the procedure, certainly not because it was trendy, but because it assures that no matter what may happen to them in the meantime, they'll still have the opportunity to reproduce using their own eggs and have their own biological children sometime in the future.
Human oocyte cryopreservation is a process where a woman's eggs are extracted and preserved for potential future use. The treatment originated in the 1960s as an experiment concerning the eggs of various non-human mammals. It has since evolved to incorporate human eggs and grown in popularity as word of the procedure continues to spread.
Egg freezing didn't really start to become well-known until 2014, when some of the world's top tech companies, Apple, Facebook, and Google, began announcing they would be offering egg freezing for their female employees as part of their benefits package.
The success of oocyte cryopreservation is highly dependent on age, as the number and quality of eggs extracted are greatly influenced by the age of the woman involved. There is a fertility timeline with different rates of successful live births among females of the following age brackets:
Age 30 and under: At least 12 eggs are required to have a 65% to 85% chance of a successful pregnancy.
Age 31 - 35: : 12 to 24 eggs are required to have the same 65% to 85% chance of a successful conception.
Age 35 and older: 24 eggs or more are required to have the same 65% to 85% chance of a successful conception.
The bottom line is that the younger you are, the better the quality of your eggs and the higher the chance of success. In some ways it's also less expensive because of the lower number of eggs you need to produce.
Your doctor will first determine the quality and quantity of your eggs through Ovarian Reserve Testing. There will be a screening for any infectious diseases you might be carrying. Your doctor will monitor your progress during the preparation stages by conducting multiple blood testings and ultrasound procedures. You will be injected with hormones to stimulate your ovaries to produce more eggs, prevent premature ovulation and help the eggs mature.
Once the eggs are ready, there is a retrieval process where you will be sedated while your doctor retrieves your eggs from its follicles. Immediately following the retrieval of your eggs, they will be stored in a freezer at subzero temperatures along with certain cryoprotectant substances that help to preserve eggs over an extended period. At this point, you'll need to rest for an entire week before resuming your regular activities.
Advantages of Egg Freezing:
You can postpone becoming a mother until you feel you're ready.
You will have more freedom to focus on your career and other important life choices because of the significantly reduced pressure you'll face with respect to having children while you're still young. With oocyte cryopreservation you're eggs remain young and healthy even after several years in the freezer.
If you need to undergo certain medical procedures, such as chemotherapy, which can negatively affect fertility and the ability to reproduce naturally, freezing your eggs in advance of the treatment will enable you to have children regardless of the outcome.
You can donate your eggs should you never choose to use them, or simply have them discarded.
Egg freezing can function as a “pregnancy insurance" of sorts if other females in your bloodline have tended to enter into menopause prematurely.
Not 100% successful in every situation. In fact, the odds of a successful pregnancy resulting after egg freezing still remain relatively low, all things considered.
While rare, egg freezing can potentially present a few fairly serious health risks.
Time-consuming. Numerous visits to the doctor are required throughout the entire preparation period.
It's expensive. At best, the procedure will cost several thousands of dollars, and at worst, if multiple attempts are required, as they often are, the costs can easily climb upwards of $30,000.
Frozen eggs have a lower success rate than embryo freezing or eggs that are fresh from the womb.
Following are excerpts from "Unleash the Girls, The Untold Story of the Invention of the Sports Bra and How It Changed the World (And Me)" By Lisa Z. Lindahl
There is an idea that has popped up everywhere from Chaos Theory to Science Fiction and New Age memes known popularly as the "Butterfly Effect." Simply put, it is the notion that one very small thing—the movement of a butterfly's wing say, or the ripple in a lake caused by a pebble being thrown into it—can cause tremendous effect far away: the butterfly's wing a tornado, the ripple a large wave on a distant shore. Cause and effect, does it have limits? The field of physics is telling us that it takes only observation to bring a thing into being. We cannot consider these areas of investigation and not acknowledge that everything—everything—is in relationship in some way or another with everything else.
So, it is evident to me that commerce of any kind is, also, just about relationships. It all boils down, on every level to this simplicity. While we usually think of relationships as occurring between people—it is far more than that.
I used to teach a course in entrepreneurship specifically for women in The Women's Small Business Program at Trinity College in Burlington, Vermont. I made this concept of relationship and its importance central in how I taught the marketing thought process. I would stress that for a product or service to be successful, it had to meet a perceived need. There is a need, and it wants to be met; or it may be thought of as a problem to be solved. Or there may be an existing solution that is less than adequate.
For example: In my universe as a runner there already were a plethora of bras available, but they were inadequate for my purpose. The relationship between my breasts, my running body, and my bra was creating discomfort and distraction. A new solution had to be found, the relationship occurring when all these things came together had to be fixed. Utilizing this point of view, one sees a set of issues that need to be addressed—they are in relationship with each other and their environment in a way that needs to be changed, adjusted.
Nowhere is this viewpoint truer than in business, as we enter into more and more relationships with people to address all the needs of the organization. Whether designing a product or a service or communicating with others about it—we are in relationship. And meanwhile, how about maintaining a healthy relationship with ourselves? All the issues we know about stress in the workplace can boil down to an internal balancing act around our relationships: to the work itself, to those we work with, to home life, friends and lovers. So quickly those ripples can become waves.
Because Jogbra was growing so quickly, relationships were being discovered, created, ending, expanding and changing at a pace that makes my head spin to recall. And truly challenged my spirit. Not to mention how I handled dealing with my seizure disorder.
"My Lifelong Partner"
Let me tell you a bit about my old friend, Epilepsy. Having Epilepsy does not make any sort of money-making endeavor easy or reliable, yet it is my other "partner" in life. Husbands and business partners have come and gone, but Epilepsy has always been with me. It was my first experience of having a "shadow teacher."
While a child who isn't feeling she has power over her world may have a tantrum, as we grow older, most of us find other more subtle ways to express our powerfulness or powerlessness. We adapt, learn coping mechanisms, how to persuade, manipulate, or capitulate when necessary. These tools, these learned adaptations, give a sense of control. They make us feel more in charge of our destiny. As a result, our maturing self generally feels indestructible, immortal. Life is a long, golden road of futures for the young.
This was not the case for me. I learned very early on when I started having seizures that I was not fully in charge of the world, my world, specifically of my body. There are many different types of epileptic seizures. Often a person with the illness may have more than one type. That has been the case for me. I was diagnosed with Epilepsy—with a seizure type now referred to as "Absence seizures"—when I was four years old. I have seen neurologists and taken medications ever since. As often happens, the condition worsened when I entered puberty and I started having convulsions as well—what most people think of when they think of epileptic seizures. The clinical name is generalized "Tonic-clonic" seizures.
In such a seizure the entire brain is involved, rather like an electrical circuit that has gone out as a result of a power surge. I lose consciousness, my whole body becomes rigid, the muscles start jerking uncontrollably, and I fall. Tonic-clonic seizures, also known as "grand mal" seizures, may or may not be preceded by an aura, a type of perceptual disturbance, which for me can act as a warning of what is coming. The seizure usually only lasts for a few minutes, but I feel its draining effects for a day or two afterwards. Although I would prefer to sleep all day after such a physically and emotionally taxing event, I have often just gotten up off the floor and, within hours, gone back to work. It was necessary sometimes, though definitely not medically advised. I'm fond of saying that having a grand mal seizure is rather like being struck by a Mack truck and living to tell the tale.
Having Epilepsy has forced me to be dependent on others throughout my life. While we are all dependent upon others to some degree—independent, interdependent, dependent—in my case a deep level of dependency was decreed and ingrained very early on. This enforced dependency did not sit well with my native self. I bucked and rebelled. At the same time, a part of me also feared the next fall, the next post-convulsive fugue. And so I recognized, I acquiesced to the need to depend on others.
The silver lining of having Epilepsy is that it has introduced me to and taught me a bit about the nature of being powerless—and experiencing betrayal. I could not trust that my body would always operate as it should. Routinely, it suddenly quits. I experience this as betrayal by my brain and body. It results in my complete powerlessness throughout the convulsion. Not to mention an inconvenient interruption of any activities or plans I might have made.
Hence, I am the recipient of two important life lessons—and I was blessed to have this very specific and graphic experience at a young age. It made me observant and reflective, giving me the opportunity to consider what/where/who "I" was. I knew I was not "just" my body, or even my brain.
So, who or what did that leave? Who, what am I? Much has been written about trauma, and about near-death experiences, both of which seizures have been classified or described as. I won't delve into that here except to say that experiencing recurrent seizures and the attendant altered states of consciousness that sometimes accompany an episode (the euphemism for a seizure) changes one. It deeply affects you. It is both illuminating and frightening. It opens you up in some ways and can close you way down in others. For me it made it easy to consider the possibility of other ways to perceive, of other realms. And as an adult I became interested in quantum physics, where Science is pushing and challenging our long-held perceptual assumptions. Me, who was poor in math and disinterested in Science while in school! So if not merely body and brain, who am I? Spirit. And with Epilepsy's tutelage, I was encouraged to question, seek, try to understand what lies beyond.
Living with Epilepsy has also given me great strength. In realizing the futile nature of trying to have "power over" Epilepsy, I developed a deep well of "power within"—that inner strength that comes in the acceptance of that which one cannot change—and looking beyond it.
Through my experience building the business of Jogbra with the unique lens afforded me by my Epilepsy partner, I came to understand more fully the nature of power and what it means to be truly powerful.
Specifically, that having power and exercising it is not simply a manifestation of the ego. It need not be "power-tripping." It is how I wield my power that matters, making the all-important distinction between creating a situation of power over, power with, or empowering and having and creating strength in oneself and others.
Being powerful is a big responsibility.
To put all this another way: do I choose to create situations in which I am able to wield power over others? Or do I choose to empower others, sharing my strengths with them, while nurturing their strengths as well? The first is not true power. It is control. The second I believe to be the essence of true and positive power: strength. And integral to creating a more harmonious world, oh by the way.
While this may be apparent, even basic to others, it was an "aha!" moment for me. Too often in the years ahead I would give away my power and question my own strengths,. Time and again, however, my inner strength, my shadow teacher's gift, helped me survive and thrive until I could take responsibility for and embrace more fully my own power.
