In vitro fertilization (IVF)<\/a> can be overwhelming, but the egg retrieval, also known as egg harvesting or egg collection, doesn’t have to be. After all the preparation with the appointments, pills, shots, and ultrasounds, you're finally getting ready to see what happens next. Here’s what you can expect from an egg retrieval procedure.<\/p>\n The IVF cycle is basically a zuped up menstrual cycle. What exactly does that mean? In a natural menstrual cycle, hormones called gonadotropins are released from the pituitary gland and help recruit one egg to mature over about 10-14 days and then signal ovulation (egg released from the ovary into the fallopian tube where hopefully it meets sperm).<\/p>\n The medications in an IVF cycle are simulating the natural recruitment process with the goal of recruiting more than one egg. Retrieving multiple eggs increases the likelihood of having high-quality embryos to transfer back to the uterus.<\/p>\n Essentially, the egg retrieval is like ovulation; however, there are more eggs involved and they are retrieved out of the body before they would ovulate on their own inside the body.<\/p>\n If a patient does not have a fresh embryo transfer, they can expect a menstrual period about 7-10 days after the egg retrieval and the ‘cycle’ is then complete.<\/p>\n Most IVF stimulation protocols start with some sort of medication to prepare the eggs and the most common is the birth control pill. Patients are often shocked when I tell them that the first step in IVF is taking birth control pills and they often say, “Isn’t that the opposite of what we’re trying to do here?” I then joke, “We need to re-brand them, no one would hesitate if I call them ‘IVF prep pills.’<\/p>\n The birth control pills are meant to prepare the eggs for recruitment. I describe it as getting them on the starting line for stimulation so that they all develop at the same rate and most of them will be mature and ready for retrieval at the same time.<\/p>\n Other ways to prep for the stimulation phase of IVF can be:<\/p>\n Suppression Check and Breakthrough Ovulation<\/strong><\/p>\n Before you start the stimulation medication, you’ll have an appointment (often called a suppression check) to check that you are ready. This usually involves an ultrasound and a blood test for estradiol (an estrogen that your ovaries produce).<\/p>\n Occasionally people breakthrough birth control pills and other preparation medications, and if so, we do not recommend starting the cycle. Breaking through birth control pills means recruiting an egg while on birth control pills and we can tell this happens if there is a large follicle on the ultrasound in combination with a higher than expected estradiol level on the blood test.<\/p>\n It is very frustrating to be ready for your IVF cycle and have it delayed but it’s the right thing to do. If we started the stimulation shots when your body has already selected an egg to start recruiting, then that is the only one that would develop to maturity in that cycle and the whole point of IVF is to recruit more than one egg.<\/p>\n If the ovaries are quiet and the estrogen level low, you are ready to start the stimulation phase of the IVF cycle!<\/p>\n Let’s take the mystery out of the IVF cycle — it’s not magic recruiting eggs—it’s science. Every menstrual cycle women may ovulate one egg but many more eggs are lost (this happens every month whether or not we are having menstrual cycles).<\/p>\n Our eggs are constantly trying to develop and then the vast majority die off (I wish we could put a pause button on this process!). Of all the eggs that we lose each month, a small group of them are recruitable (able to respond to stimulation medication, if given).<\/p>\n In a natural cycle, the pituitary gland makes enough gonadotropins, mostly follicle-stimulating hormone (FSH),<\/a> to recruit one egg and when the ovaries make enough estrogen to signal that the egg is mature the pituitary gland produces a surge of another gonadotropin, luteinizing hormone (LH)<\/a> which induces ovulation of that mature egg.<\/p>\n We are mimicking this process in IVF with the goal of recruiting more than one egg. We give gonadotropins for 10-14 days in the form of shots to recruit the eggs that are available. These shots are the same hormones a woman’s body makes each month, just in higher doses.<\/p>\n It’s important to know that every woman is different, and every cycle is different. The same dose of medications can produce a different number of eggs in different women and even in the same woman but over different menstrual cycles.<\/p>\n Women are followed closely throughout the cycle with ultrasounds (follicle sizes increases as eggs mature) and blood tests (estrogen levels increase as eggs mature).<\/p>\nWhat is an Egg Retrieval Procedure?<\/h2>\n
