The first child conceived by IVF was Louise Joy Brown, and since her birth, seventy-five percent of women who have undergone this procedure have become mothers of healthy, happy babies. This procedure has an overall fifty-five percent birth rate. In vitro fertilization was first successfully achieved in the s, when Dr. Walter Heape, of Cambridge, UK, managed to transplant a fertilized ovum into a rabbit. The idea of IVF was not seriously discussed in humans until , when two Harvard researchers published a paper suggesting it could be viable. However, it would be when Dr. Chang achieved the first live birth using IVF techniques, in a rabbit. Regrettably, this inaugural attempt ended in a miscarriage. As medical techniques and capabilities have improved, so has the prognosis and viability of IVF. New chemicals and methodologies, coupled with discoveries about how unfertilized and fertilized ova behave both in the human body and in IVF culture media, have made this method of conception more effective and efficient.
Comparing Two Types of Endometrial Activation Prior to Embryo Transfer
A frozen embryo transfer FET cycle means thawing one or more embryos frozen during a previous treatment cycle and transferring that embryo or embryos to the uterus in order to try to establish a pregnancy. The process is a routine procedure at Life Fertility Clinic. When ovaries are stimulated in a typical IVF or ICSI cycle, they produce multiple eggs for insemination and this often leads to a number of healthy embryos being created.
As only one or two will be transferred to the uterus immediately, the rest can be frozen to use in another IVF cycle if the first transfer does not result in a pregnancy, or at a later time to create a sibling. Occasionally a woman having IVF treatment will be advised to freeze all her embryos and not to transfer any immediately if the lining of the uterus has not developed to a suitable stage or if she is at risk of developing ovarian hyper-stimulation syndrome OHSS.
Frozen embryo transfers (FET) constitute nowadays an integral part of in terms of scheduling the activity in an IVF unit since the transfer date.
Whether you are trying to conceive on your own or undergoing fertility treatment the two week wait can seem like an eternity. This is the time between suspected ovulation — or in the case of those undergoing fertility treatment, the time of insemination or transfer — and when the first pregnancy test can be taken resulting in reliable results. To help navigate the curiosity and unknowns, we gathered some question from our community, ran them by our nurse educators, and came up with answers to your most pressing two week wait questions.
This period of time is referred to as the two week wait. The blood test — officially called a beta hCG blood test — detects hCG and is the most accurate indication of pregnancy. Traces of the administered hCG may still be in your bloodstream and detectable by a test even if implantation has not occurred.

Study record managers: refer to the Data Element Definitions if submitting registration or results information. Physicians at the Women’s Institute perform over embryo transfer procedures every year. Implantation is essential for successful ART and IVF procedures, and many interventions have been studied to possibly improve implantation rates and thus pregnancy and live birth rates.
Endometrial activation is one such intervention, sometimes referred to as endometrial “activation” or “scratch,” and it is defined as “intentional endometrial injury, such as endometrial biopsy or curettage, in women undergoing ART”. A previous study found that implantation rates, clinical pregnancy rates, and live birth rates were more than twofold higher in women who underwent endometrial biopsy in the cycle before subsequent IVF treatment.
Another study which examines endometrial activation prior to IVF similarly has concluded that endometrial activation prior to the embryo transfer cycle significantly improves clinical pregnancy rates and live birth rates in women undergoing ART. Although the type of endometrial procedure is not specified, the timing activation was found be most effective when performed in the cycle prior to the embryo transfer.
Frozen Embryo Transfer: Natural Cycle
Like the pregnancy wheel your fertility specialist , OB or midwife uses, this page will help calculate when your baby is or will be due. If you conceive through IVF of any kind, you may use either the retrieval or transfer date to calculate this. Please note that your due date is only an estimate of when your child will be born.

The information should not be construed as dictating an exclusive course of treatment or procedure to be followed. As soon as data from the last menstrual period, the first accurate ultrasound examination, or both are obtained, the gestational age and the estimated due date EDD should be determined, discussed with the patient, and documented clearly in the medical record.
Subsequent changes to the EDD should be reserved for rare circumstances, discussed with the patient, and documented clearly in the medical record. When determined from the methods outlined in this document for estimating the due date, gestational age at delivery represents the best obstetric estimate for the purpose of clinical care and should be recorded on the birth certificate.
For the purposes of research and surveillance, the best obstetric estimate, rather than estimates based on the last menstrual period alone, should be used as the measure for gestational age.

Infertility is a far more common problem than most people realize. Fortunately, at The Center for Assisted Reproduction, or CARE Fertility, we offer a range of fertility treatments to help patients overcome fertility issues so they can experience the joys of pregnancy and parenthood. One of the most successful fertility treatments is IVF.
IVF, or in vitro fertilization, assists throughout the reproductive process to maximize the chance of a successful pregnancy. When an IVF pregnancy is confirmed, patients are eager to determine when their baby is likely to be born. Since IVF is different than a traditional pregnancy, the due date can be calculated based on the date of egg retrieval or transfer.
Our fertility specialists are happy to assist with calculating your IVF due date after treatment at our Dallas, TX fertility clinic. A typical pregnancy lasts 40 weeks, or day. When a woman conceives naturally, doctors determine the estimated due date based on the first day of the last menstrual cycle. This method is used because most people do not know exactly when they ovulate. A woman with a regular day menstrual cycle typically ovulates on day However, ovulation can actually occur earlier or later than this date, so a due date is only a rough estimation of when the baby is likely to be born.
Women who undergo IVF do know exactly when they ovulated, so it is more accurate to calculate a due date following IVF treatment.

If anything, IVF babies are more likely to be born sooner. But it does mean your due date is less likely to be changed as your pregnancy progresses.
