When LMP and Ultrasound Dates Don’t Match: When to Redate?

When LMP and Ultrasound Dates Don’t Match: When to Redate?

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.
