After all the items on your IVF checklist are complete, your fertility coordinator will send in your prescription, and create a calendar that outlines the individual stimulation protocol developed by your physician. The calendar dating is based on your menstrual cycle start, and includes a schedule of medications and appointments for your IVF cycle. We want to provide you with the best chance for success and part of this process is injection training. During the injection class you will participate in a hands-on injection technique demonstration.

Most pregnancies last around 40 weeks or 38 weeks from conception , so typically the best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP. Another way to do it is to subtract three months from the first day of your last period and add seven days. So if your last period started on April 11, you’d count back three months to January 11 and then add seven days, which means your due date would be January Calculating your due date based on the first day of your last period works well for women who have a relatively regular menstrual cycle.

But if your cycle is irregular, the LMP method may not work for you.

An embryo transfer is scheduled at a later date, once the biopsy results have been returned and the female partner has recovered from her egg retrieval.

You may undergo a frozen embryo transfer FET cycle whenever you have frozen embryos and wish to use them. This may be after the delivery of a child when you wish to come back and use your frozen embryos to grow your family, or it could be after an unsuccessful stimulated in vitro fertilization IVF cycle in which you had embryos cryopreserved. Note: You must undergo a fresh stimulated IVF or donor egg cycle first, in order to have embryos to freeze.

You need to have current within the last year infectious disease bloodwork. Additionally, if you are returning after a delivery or certain types of gynecological surgery, your physician may require an updated mock embryo transfer MET and a hysterosalpingogram HSG , if indicated. You and your partner will need to update your informed consents for FET cycles every 6 months. Both partners must sign. When you decide to begin a frozen cycle, please contact our office and let us know.

We will then review your records to ensure your pre-screening is up to date. If necessary, we will order any repeat screening tests. If appreciable time has passed since you last consulted with your physician, we will schedule a follow-up visit with your physician. A FET cycle will take approximately 6 to 8 weeks. A cycle typically begins with 3 to 4 weeks of daily birth control pills to suppress the normal ovarian cycle, as it would lead to ovulation.

After the course of birth control, you will need a baseline assessment involving bloodwork and ultrasound.

Frozen Embryo Transfer

You may have been treated with fertility drugs, undergone artificial insemination, or you may have had laparoscopic surgery for fibroids or endometriosis. The problem may be traced to tubal function, pelvic adhesions, egg quality, or pelvic inflammation. It is also possible that the sperm can not get into the egg because of low sperm count and motility or thickened egg shell. What can be done now?

IVF is the process of fertilizing an egg with a sperm in the laboratory in vitro to form an embryo. The embryos are then transferred into the uterus to initiate a pregnancy and a live birth.

IVF transfer date: If you’ve gone throughassisted reproductive technology cycles, you can calculate your due date more precisely using your IVF.

Frozen embryo transfer, or FET, is an assisted reproductive technology procedure in which a previously frozen embryo is thawed and transferred it into an appropriately prepared uterus in order to have a baby. Frozen embryo is a term for embryos that are not transferred during an IVF cycle and are deemed suitable for cryopreservation, or freezing.

The best embryos are most commonly selected for transfer in fresh IVF cycles. Should suitable quality embryos remain, they can be frozen for later use. Not all cycles have embryos that are suitable for freezing. Occasionally a freeze-all cycle may be recommended. Instead of transferring an embryo following IVF, all embryos are frozen for later thawing so that the best surviving embryo can be transferred at a later time.

Freeze-all cycles may be suggested for a variety of reasons such as if the woman is ill or has uterine bleeding that could result in the transfer being less likely to achieve a successful pregnancy. Other reasons to do a freeze-all are in cases where either a uterine polyp may jeopardize implantation due to its size and location, or in cases where intrauterine fluid has accumulated, lowering the probability of the embryo being able to adhere to the uterine wall.

In cases of ovarian hyper-stimulation syndrome OHSS , a freeze-all is often recommended as the risk of OHSS severity is significantly reduced if pregnancy does not occur. Still another indication for a freeze-all is in cases where pregnancy has not resulted from multiple prior fresh embryo transfers due to potential detrimental effects resulting from hormonal fluctuations or imbalances.

Before starting an FET cycle, the physician needs to assess the uterine cavity using one of three tests:. If any abnormalities are detected, they should be corrected surgically before going forward with a frozen embryo transfer. There are two protocols used for FET cycles.

Comparing Two Types of Endometrial Activation Prior to Embryo Transfer

Kovacs, What factors are important for successful embryo transfer after in-vitro fertilization? The success rate after treatment by in-vitro fertilization IVF depends on the characteristics of the couples being treated, and the performance of the clinic. The former cannot be changed, and embryology laboratories have worked hard to optimize procedures.

Numerous studies have been reported on how to improve insemination and culture procedures. The clinicians’ role is confined to stimulation, oocyte collection and embryo transfer. Although each edition of journals on reproductive medicine contains some reports on various stimulation regimens, the physical aspects of oocyte collection and embryo transfer have received limited interest.

Less Stress – FET cycles are more predictable. Patients have a choice of transfer dates months in advance which will then determine the date their cycle will be.

The common first step will be a dating scan between weeks as we like to check your baby before 10 weeks. Before 7 weeks it may be too early to acquire this information. To obtain the best images possible, this scan is routinely performed internally and perfectly safe to perform during early pregnancy. At 7 weeks gestation a pregnancy sac should be seen within the uterus.

Within this sac will be an embryo, heart motion and yolk sac should be visible. Approaching 8 weeks, early brain formation is identified with a black space in the head called the rhombencephalon. Sometimes it may be too early to gather all the information required to confirm the stage of your pregnancy.

The IVF Process

First day of last period: The best way to estimate your due date is to count 40 weeks, or days, from the first day of your last menstrual period LMP. Another useful way is to subtract three months from the first day of your last period and add seven days. Conception date : If your cycle is irregular, the LMP method may not work for you. Just add days to get your estimated due date.

If you are already pregnant, then book an appointment at Motherhood Hospitals. It offers a complete birthing experience to couples by hand-holding them through their journey towards parenthood.

Check your IVF or FET due date at Your IVF Journey. It works if you’ve had donor eggs, donor embryos or a frozen embryo transfer (FET).

If you are a human, do not fill in this field. A successful IVF cycle results in pregnancy, and with it comes many questions and anticipation. When will the baby arrive? What is my due date? Newly pregnant women have many resources to answer those questions. An IVF due date calculator takes the guesswork out of it. The IVF pregnancy calculator are simple, free, and usually easy to use.

The process of embryo implantation is carried out during the receptive stage of the endometrium in the midluteal phase of the menstrual cycle, known as window of implantation WOI. It has been assumed that the WOI is not a constant variable in all women and the determination of its displacement is of crucial importance, especially for patients with recurrent implantation failure RIF.

Furthermore, in rare cases it could have different duration and position in the menstrual cycle even in the same woman but during different periods. Here, we report a year-old woman with RIF, who was previously classified as idiopathic but has now been diagnosed as having a variable WOI. This interpretation was done after the performance of immunohistochemical and histomorphological analyses of endometrial biopsies taken in the midluteal phase during three sequential menstrual cycles.

Finding the best moment in the menstrual cycle for embryo transfer is a crucial follicle and it was done by dating the corpus luteum using sonographic criteria.

Because the human egg is capable of fertilization for only 12 to 24 hours after ovulation the date of ovulation may be taken as being the date of conception. However, ultrasound determination of the date of ovulation has the same imprecision as does the ultrasound estimate of the gestational age and, therefore, a precise date of conception cannot usually be determined as with in vitro fertilization.

In addition, although a woman is most likely to become pregnant if she has sex on the day of ovulation conception may also occur from live sperm still in her reproductive tract on the day of ovulation if she had sex for up to five days before ovulation [26,27]. The due date may be estimated by adding days 9 months and 7 days to the first day of the last menstrual period LMP.

This is the method used by “pregnancy wheels”. The accuracy of the EDD derived by this method depends on accurate recall by the mother, assumes regular 28 day cycles, and that ovulation and conception occurs on day 14 of the cycle. Use of the LMP to establish the due date may overestimate the duration of the pregnancy, and can be subject to an error of more than 2 weeks []. In cases where the date of conception is known precisely, such as with in vitro fertilization, the EDD is calculated by adding days to the date of conception.

Ultrasound uses the size of the fetus to determine the gestational age the time elapsed since the the first day of the last menstrual period. The accuracy of the ultrasound estimate of the gestational age varies according to the gestational age. The Society of Obstetricians and Gynaecologists of Canada recommends the earliest ultrasound with a crown rump length equivalent to at least 7 weeks or 10 mm should be used to determine the gestational age [28]. The American College of Obstetricians and Gynecologists recommends that ultrasound-established dates should take preference over menstrual dates when the discrepancy between ultrasound dating and LMP is.

Other Methods For Estimating the Gestational Age Clinical Examination A pelvic examination supported by good menstrual records in the first trimester has been reported to be a reliable method for dating of pregnancy [9]. Doppler Ultrasonography The fetal heart can be heard using Doppler ultrasound by 10 to 12 weeks in most patients [10].
