Understanding Conception and IVF

QUESTION
On MedVacation’s website, you state that IVF treatments with your fertility clinics abroad take, on average, 18 days, if the patient starts her treatments with your clinic on Cycle Day 1. How come this is shorter than in the States? Where I live, clinics average 37 days from start to implantation (3 day on birth control, 5-10 days on Lupron, ultra sound, stimulation med 9-13 days, 1.5 later egg retrieval, 3-5 day transfer = 37 days).

ANSWER
ivf-clinics-in-usWe hear this type of questions from our clients on regular basis. The answer to this question is remarkably simple – your local IVF clinics in the U.S. perform egg retrieval during certain time of the month and sync up their patients’ menstrual cycles with clinics’ retrieval schedules. Since these clinics perform egg retrieval on certain days, they time IVF cycles by putting patients on birth control and/or Lupron.

Moreover, Lupron is also taken during the IVF cycle. It is used to decrease the level of LH hormone women make for a short time and to prevent ovulation. This LH surge happens when the ovaries release the eggs, or ovulate, before the desired time or before the time of the egg retrieval. Therefore, you can add days on Lupron to your IVF cycle days rather than count those consecutively.

MedVacation's IVF clinics abroad perform egg retrieval every day ..... even on weekends, if there is a need for that. Therefore, we typically don't put patients on OCP, but have done so in the past if they wanted to have egg retrieval on certain day. Here is a link to our page that talks about typical IVF cycle.

It may also be helpful to understand the process of natural conception. Think about your IVF cycle as natural conception process aided by our fertility specialists. Human conception is a relatively simple and yet amazingly complex process.

The process begins on the first day of your menstrual cycle. We also call this day Cycle Day 1. During the next 12 to 14 days occurs what fertility specialists call follicular phase, the event that results in the ovulation of a mature egg. It’s called "follicular phase," because the eggs develop in a fluid-filled sacs called the follicles. On Cycle Day 1, your body starts developing follicles. Many eggs begin to develop during each monthly cycle. Naturally, however, usually just one of the eggs will reach maturity while the rest undergo a process known as atresia, or degeneration, and are lost forever. When that one egg is mature, it is released from the ovary. With IVF medications, our doctors help your body to develop more than one egg during the first 10 days of the cycle. The egg will be capable of being fertilized for only the next 12 to 24 hours. If not fertilized within that time, it is simply reabsorbed by the body.

As the egg begins it descend through the fallopian tubes, it meets with sperm and gets fertilized. Ovulation triggers many other changes in the body. The cervical mucus becomes penetrable, and the lining of the uterus is getting ready to accept an implantation. In contract to the natural process, our IVF doctors will retrieve the mature eggs on Cycle Day 12. It is important to note that it may take up to 17 days to retrieve your eggs, if your ovaries don't respond well to medications. Normally IVF medications are taken for 10 days. However, if patient’s follicles maturing in her ovaries don’t grow well, she may be instructed to take medication up to five days longer.

Typically, our IVF clinics perform egg retrieval on Cycle Day 12. The very same day, the eggs are fertilized with sperm either by conventional insemination or by Intracytoplasmic Sperm Injection (ICSI). The eggs will be checked the following day to document fertilization and again the next day to evaluate for early cell division. Until recently, embryos were cultured for three days and then transferred to the uterus and/or cryogenically frozen for later use. Our IVF clinics now have the ability to grow the embryos for five or six days until they reach the blastocyst stage. Blastocysts have a greater chance of implantation. This, in turn, allows our IVF doctors to transfer fewer embryos and lower the risk of multiple births while increasing the chance of pregnancy.

The final step in the IVF cycle is the embryo transfer. As it is the case with the natural fertilization, not all embryos will grow in the laboratory dish. The embryo(s) that continue to divide and grow is transferred into recipient’s uterus about the time it would arrive there in a natural conception. Unused embryos can be cryopreserved for later use.
