The Frozen Embryo Transfer (FET) process using donor embryos is the same as the FET process using your own embryos. This is referred to as Donor Frozen Embryo Transfer (DFET). The procedure can be performed during a medicated or unmedicated cycle. Some clinics prefer to do a mock cycle first to ensure that you will respond appropriately to any medications used, and that they can insert the catheter through the cervix without incident.

Overall survival rate after freezing and thawing is about 85%. The likelihood of pregnancy after a transfer of frozen-thawed embryos is about 40 to 50%. Offspring born from frozen embryos has a similar rate of congenital abnormalities as does offspring of the general population.

This is the process in which fertilized eggs are placed inside your uterus using a flexible catheter (Wallace). This procedure is painless. Insertion of the catheter is done slowly. Sometimes it may be necessary to use a firmer catheter (Cook K Jet) and ultrasound guidance to insert the catheter. Removal of the catheter is also done slowly. After the catheter is removed, it is checked under the microscope to ensure that all the embryos have been placed in the uterus.

The cryopreservation process does not appear to adversely affect birthweight, perinatal mortality rates, birth defects, growth or health of children during infancy and early childhood over children born from fresh IVF transfers. However, the long term affects of cryopreservation over a lifetime have not been studied extensively in humans, and since this technology is only about twenty years old, most of the children whose parents utilized cryopreservation are still in the process of growing up.

The Centers for Disease Control and Prevention (CDC) publishes an annual report on Assisted Reproductive Technology (ART) statistics in the United States. The information is self-reported by participating fertility clinics. The most recently published report, from 2002, indicates that the live birth rate for transfer of frozen embryos created with non-donor eggs is 28%, and when the embryos were created with donor eggs it is 38%.

Animals that are produced using Embryo Transfer (ET) and Cloning are not eligible for inclusion in the herdbook. Although such technologies can be effectively used in a thoughtful conservation plan with carefully selected matings, indiscriminate use can have a disastrous effect on a gene pool as tenuous as the Randalls'. Over nearly two decades, Randall breeders have been following a breeding protocol proscribed by Dr. Phil Sponenberg.

Patients are asked to avoid strenuous activity that would strain the pelvic area, such as climbing stairs and lifting objects heavier than 15 pounds. Any formal exercise program such as weight lifting aerobics, jogging, etc. should be discussed with the physician. Also, the patient is advised not to take tube baths, douche, insert tampons or have sexual intercourse until the pregnancy test.

The medications used will based on clinic protocols, and may be adjusted for an individual patient based on her body’s response to certain drugs and the outcome of prior cycles. Some clinics will perform a non-medicated cycle for patients who produce an adequate uterine lining without assistance, but medicated cycles are more common.

Yes. There are higher pregnancy rates using fresh embryos; however, there is still some discussion on this issue. The higher rates could be a function of the fact that the best quality embryos are used first. It is hard to say if the difference in rates can be attributed to the freeze/ thaw or to the quality of the embryos. We have clients come to us from all over the world. Many American couples ask this question.

For immediate transfer: The donor mare is bred to the stallion of choice. Her cycle if followed closely so that we know exactly when she ovulates her follicle. Seven days following her ovulation date we will flush the mare for an embryo. If we retrieve an embryo it is transferred directly into the recipient mare. For frozen embryos: The breeding is the same as above, however, we will flush for an embryo Six days after ovulation.

No. Your embryos have now returned to their natural environment, where they would be had fertilization been achieved spontaneously. Thus, you can lead a completely normal life, just like any woman who still doesn't know that she has conceived and will soon be pregnant.

A number of important elements need to be considered early on in the known embryo donation process if the recipient does not plan to travel to the donors’ clinic for the transfer. The recipients must do some homework on their end to determine: Ideally, the recipients will have researched these questions and feel confident that their clinic is willing to work with known donor embryos prior to reaching an agreement with a donor couple.

There does not appear to be any difference in the chance of pregnancy whether there is bed rest or not. However, it is preferred that you do not to engage in strenuous activities.

It has not been proven that avoiding coitus during the two weeks after embryo transfer makes any difference to the chance of pregnancy. However most couples prefer to abstain from coitus.

If you have a regular ovulatory cycle. One way is to test your urine twice daily from day 12 to day 16 for the Luteinizing hormone surge. This would show as a definite double line in a plastic cassette. You will be given an injection of HCG 10,000 units (Pregnyl) under your skin of your tummy . If your embryos have been frozen at the 6 or 8 cell stage, transfer will take place five days after the injection.

Betting on single embryo in vitro not a bad gamble Procedure improves so couples need not risk multiple births By JULIE DAVIDOW SEATTLE POST-INTELLIGENCER REPORTER Four years into her quest to get pregnant, after she had decided to try in vitro fertilization, 35-year-old Lisa Goss had a decision to make. Did she want one or two embryos put back in her uterus? With two, she might have twins; with one, she might be reducing her odds of having a baby at all.

Seller: Anyone currently in a lease whose financial company allows for lease transfers can use our services to sell their lease. Buyer: Any driver looking for a late model vehicle with a shorter term lease and no downpayment can shop at Easyrelease. Lessor/Leasing Company/Finance Company: This is the company who owns the car and to whom monthly payments are made. They will perform a credit check on the buyer of the lease to determine whether he/she is eligible for the lease.

If more eggs are normally fertilized and divide to form healthy-looking embryos than is advisable to replace during the treatment cycle, the additional embryos can be frozen and stored for replacement in the future. Once frozen, the embryos can be maintained in storage for several years, but we encourage replacement within 2 years of fertilization whenever possible.
