Our Texas IVF clinic is conveniently located in Dallas and we have extensive experience with all procedures including IVF , ICSI, assisted hatching, blastocyst transfer, PGD, and other micromanipulation techniques. We also have years of successful clinical surgical experience including tubal reversal surgery.

Our Donor Egg Program also located in Dallas, Tx, is one of the largest and most successful in the Southeast. Superior IVF success rates are important to controlling infertility treatment costs as often fewer cycles are required to achieve pregnancy.

IVF success rates are influenced by many factors including female age, the presence of male infertility, genetics, previous treatments, and others. While no one can predict a particular outcome, our physicians always discuss IVF success rates in detail with each couple.

IVF Overview

IVF refers to the creation of embryos by placing sperm and eggs in a test tube or culture dish in a laboratory setting. Oocytes (eggs) must be obtained by stimulating the ovaries with FSH or hMG fertility drugs because many eggs are required to produce enough quality embryos for transfer.

During an IVF cycle, once the eggs mature, they are retrieved in a procedure termed transvaginal oocyte retrieval. Patients are instructed to inject hCG approximately 36 hours prior to egg retrieval to mimic the natural cycle release of LH.

IVF oocyte (egg) retrieval is performed in an operating room under light sedation using intravenous anesthesia. The oocyte retrieval procedure involves the passage of a needle Texas IVF Clinicthrough the thin posterior wall of the vagina into the ovarian follicles and aspirating the oocytes.

Sperm is processed and used to fertilize the oocytes and create embryos. These embryos are allowed to grow in the incubator for an additional 3 to 5 days before being transferred. If blastocyst transfer is attempted, the embryos will incubated until they have differentiated into two distinct cell types, usually 5-7 days.

Once the embryos mature, the patient is scheduled for embryo transfer. The transfer procedure uses a small catheter inserted through the cervix using ultrasound guidance, which places the embryos directly into the uterus with the hope that at least one will implant in the endometrium (lining of the uterus), and result in a pregnancy.

IVF Cycle Pretreatment Testing

Before an IVF treatment cycle patients will consult with their fertility specialist (Dr. Chantilis, or Dr. Lee) to discuss their treatment and prognosis. After a treatment plan has been decided, there will be pretreatment testing in order to optimize chances of pregnancy. Most women will need follicle stimulating hormone (FSH) and estradiol blood tests performed on the third day of their cycles (days 2, 3, or 4 are acceptable). These tests will be used to help determine the responsiveness of the ovary to fertility drugs  and will be used to determine the initial drug starting dosage.

IVF candidates should have a uterine evaluation (within 2 years of the procedure) such as a hysteroscopy, hysterosalpingogram (HSG), or sonohysterography to ensure that the endometrial (uterine) cavity is normal. Most abnormal uterine cavities will need to be corrected before undergoing in vitro fertilization. Our Texas IVF clinic location is where many of these procedures are performed.

The husband must have a semen analysis within 6 months from the intended treatment cycle to rule out male infertility. Additionally, we ask that all couples (both husband and wife) have an HIV test within 1 year before undergoing a treatment cycle.

Ovarian Stimulation

IVF patients will undergo ovulation induction with gonadotropin(FSH) fertility drugs. These products are administered according to treatment protocols.

You should experience a menstrual period within 7 to 14 days from starting the Lupron injections. Please notify the clinic when you start your period so that we may schedule a baseline sonogram and blood estradiol test. The purpose of these tests is to confirm that the Lupron has, in fact, suppressed your ovaries to a baseline state.

This means that your ovaries should contain no follicles that are greater than 15 mm in size, and your blood estradiol level should be less than 50 pg/ml. In approximately 10-15% of patients, one or both of these two conditions are not met. Depending upon the results of these tests, we may extend the Lupron medication for another week and ask you to return for another sonogram and blood estradiol test, or occasionally may perform an ovarian cyst aspiration (performed in the office).

After ovarian suppression has been achieved with Lupron or Ganirelix Acetate/Cetrotide, ovarian stimulation using gonadotropin fertility medication may commence at a scheduled time referred to as the cycle start. On the cycle start day, you may be instructed to reduce the initial dose, which will be continued throughout the stimulation phase of your cycle until hCG is administered.

Fertility drug dosages are individualized for each patient will be based upon age, weight, number of eggs, cycle day 3 FSH, estradiol levels, and response to previous stimulation cycles. In vitro fertilization patients will take this initial dose of medication for 2 days before returning on the morning of gonadotropin Day 3 for an estradiol blood test. Your dose may be changed based upon the level of estradiol.

IVF patients will take medication for 2 more days before returning on medication Day 5 for an estradiol blood test. Sonograms are conducted starting on Day 7 of stimulation. Patients will usually return for follow-up sonograms and estradiol blood tests usually every 1 to 3 days in order to monitor follicular growth.

In general, you will be asked to return more frequently towards the end of your ovarian stimulation. Most people require 8 to 12 days of ovarian stimulation, and most people require 4 to 6 sonograms and/or estradiol levels during this period of time.

Texas IVF Clinic, Dallas-Ft. Worth Fertility Associates- Treatment Protocols

Different treatment protocols are employed for different patients. Remember that every patient's treatment is individualized and may not match a specific protocol. Some patients may require much higher doses of FSH, others might receive only pure FSH such as Gonal-F or Follistim whereas some my have Repronex incorporated into their protocol.


Oocyte (Egg) Retrieval

IVF patients should have nothing to eat or drink in the eight (8) hours prior to retrieval. The egg retrieval will be performed on the 6th floor of the Margot Perot building at the Presbyterian Hospital campus of Dallas. The procedure is conducted under intravenous sedation, administered by an anesthesiologist, so that patients will be comfortable during the egg collection.

Most patients are candidates for vaginal ultrasound guided egg retrieval. This procedure involves the use of a vaginal probe sonogram to guide a needle through the posterior wall of the vagina into an ovary. The vagina is otherwise protected from the needle because it is passed through using a protective guide. The procedure usually last about 30 minutes. Patients are allowed to go home after a 1 to 2 hour recovery.

After the egg retrieval, procedures such is ICSI may be performed. In this procedure, the sperm is inserted directly into the egg. Other procedures, such as assisted hatching might also be performed.

We have an active and very successful donor egg program at our Dallas Texas location. An egg donor is used when the mother can no longer use her eggs for conception.

Collection of Semen Specimens

A semen analysis fertility test must be performed within 3 months prior to the cycle at Presbyterian Hospital Andrology Laboratory on the first floor of the Margot Perot building. A semen specimen will be required on the day of egg retrieval, and should be collected in the ARTS center. Abstinence from intercourse is required for 2 to 4 days prior to egg retrieval. We recommend that ejaculation occurs the same evening when hCG is given to assure better quality sperm for the procedure.

If significant male infertility is present, you may be asked to prolong the period of abstinence before the day of the oocyte retrieval. Specific instructions regarding this collection will be reviewed at a later date. If you anticipate any collection difficulties, please notify your doctor or one of the ARTS nurses.

Oocyte Culture

As soon as possible after the egg retrieval, you and your husband will be given the preliminary results on the number of oocytes retrieved. Please realize that the quality, number, and/or maturity of the eggs may not be evident because the eggs are surrounded by follicle cells (called granulosa cells), which sometimes prevent quick evaluation. Superovulation yields various types of eggs, including mature, immature, post mature, and nonviable eggs. Following the egg retrieval, you will be given detailed instructions concerning the next steps of your treatment.

IVF patients participating in our Texas donor egg program will consult with the donor egg coordinator. The mature eggs will be retrieved from the donor in the same manner as above after FSH stimulation. They will then be combined with the father's sperm.

Please leave a list of times and phone numbers with the staff to assist us in meeting your needs promptly. Someone will need to drive you home following this procedure. If you experience pain, bleeding (more that a period), temperature > 101 degrees, or other side effects following the procedure, please notify your physician.

IVF patients are contacted by our staff one day after the egg retrieval and given the status report on the number of oocytes that fertilized. At this time, fertilization is seen in most cases, but embryo replacement can only be confirmed when the fertilized egg divides normally, usually after another day. As you know, one of the risks of in vitro fertilization is lack of fertilization. Sometimes a reason for this is understood, but many times no reasons are evident. If this occurs, please consult your fertility specialist regarding future plans.

Blastocyst Culture

Sometimes in an IVF cycle a blastocyst will be transferred. A blastocyst is an embryo that has been cultured from 5-6 days and differentiated into two distinct cell types. This compares to embryos that are cultured for 3 days until the 6-8 cell stage. Blastocysts are "heartier" and more likely to implant and produce an ongoing pregnancy. For this reason, fewer blastocysts, sometimes one, can be transferred to the uterus in a cycle. This dramatically reduces the rate of high order multiple births. Blastocyst transfer cannot be used in every couple and your physician will discuss its appropriateness in your case.

Preimplantation Genetic Diagnosis (PGD)

Our Texas IVF clinic location in Dallas is where PGD is conducted on the couple's embryo(s). PGD is employed to screen embryos for specific genetic abnormalities and for identifying broken, translocated, or an abnormal number of chromosomes. After the PGD procedure, the screened embryos will be transferred to the uterus.

Embryo Transfer

On the day of your embryo replacement, report to the ARTS Center 30 minutes prior to your scheduled embryo replacement time. Husbands are encouraged to be present. The procedure is similar to having an intrauterine insemination ( IUI ). You will rest on your back at the ARTS Center for approximately one hour. We will leave you and your husband alone during this time. You must have someone with you to drive you home after embryo replacement.

If a couple is scheduled for the PGD (preimplantation genetic diagnosis) procedure, a small biopsy will be taken from the embryos prior to transfer. This cellular material allows us to identify the sex of the embryo and to screen for certain specific genetic diseases.

Luteal Phase Support

On the day after your oocyte retrieval, you will be instructed to start progesterone injections. Progesterone is a hormone produced by the ovaries only during the post-ovulation, or luteal phase, of your ovarian cycle. Progesterone develops the endometrial lining of your uterus to support and maintain pregnancy. Although your ovaries are producing progesterone, supplementation is required because some of the cells, which produce progesterone in the ovary, are removed during the egg retrieval, and some of the medications you received may contribute to a progesterone deficiency after the oocyte retrieval.
