Embryo Freezing
Freezing embryos is a routine part of the IVF/ICSI process and approximately 70% of patients end up with some embryos in storage. Freezing embryos of excess good quality after IVF allows for the transfer of fewer embryos in the stimulated IVF cycle and, therefore, ensures fewer high-order (triplets or more) multiple births. This process provides patients with a “back-up” should the initial fresh embryo transfer not result in a pregnancy, at a much lower cost than starting IVF all over again and often with minimal medications.
- Higher frozen embryo transfer success rates have allowed many of our patients to achieve more than one pregnancy from a single cycle of ovarian stimulation. Embryos can be frozen at any stage of development during the IVF process.
- Eggs that are fertilized can be frozen as early as 1 day after an egg retrieval procedure, but it is more common to allow embryos to develop for a number of days before freezing them. This allows us to observe how well the embryos are developing so that only embryos with a good probability of establishing a pregnancy are frozen.
- Embryos tolerate freezing very well and we expect over 90% of embryos to survive the process. Pregnancy rates with frozen/thawed embryos are as good as pregnancy rates for embryos that were transferred fresh without ever being frozen.
Frozen Embryo Transfer
‘Frozen embryos’ is a term used to refer to those embryos that are not transferred during the index in -vitro fertilization (IVF) cycles and are subsequently cryopreserved.
A frozen embryo transfer can be used to produce a viable pregnancy by first thawing the frozen embryo, and transferring it into an appropriately prepared uterus.
It is a simple procedure wherein a patient is provided with hormonal medications to develop uterine lining, from day 3 of menses. Serial blood tests and ultrasound scans are done to monitor the uterine lining/endometrium. Then the optimal time in the patient’s cycle is determined and embryos are transferred into the womb.
Indications:
- Ovarian hyperstimulation syndrome (OHSS).
- Inadequate uterine lining.
Frozen embryo transfer success rates:
The success rates of an FET cycle are comparable to fresh IVF cycles and sometimes result in a higher success rate because of the opportunity to optimize the lining of the uterus before implantation, among other reasons. Both fresh and frozen cycles have the same primary indicator for success: the maternal age at the time of embryo freezing.
All Services
First step towards infertility is correct diagnosis and NOT treatment.
Blood Test
A fertility blood test is used to measure your hormone levels and is usually the first fertility test that your doctor will prescribe if you are finding it difficult to conceive and suspect that you may be infertile.
Semen Analysis
A semen analysis is often recommended when couples are having problems getting pregnant. The test will help a doctor determine if a man is infertile.
Free Counselling
Motherhood Psychological counselling is necessary for patients undergoing infertility treatments to ensure that their anxiety and stress levels are not aggravated.
Ultrasound
The primary use of imaging in infertility is to assist clinicians to diagnose the ethology of a couple’s infertility and to assist in the delivery of safe, effective treatments that will lead to a high probability of conception.
Ovulation Induction
Ovulation Induction involves taking medications to stimulate the development of female eggs in the ovaries.
IUI
Intra Uterine Insemination is a treatment used for treating infertility. It involves placing male sperms directly inside a women’s uterus to facilitate fertilisation.
ICSI/IVF
Vitro Fertilization is one of the Assisted Reproductive Technologies (ART) commonly referred to as IVF or Advance IVF.
PESA/TESA
Assisted Reproductive Technology (ART) is the best option for many couples struggling with infertility.
Endoscopic Fertility Surgeries
Uterine problems such as endometrial polyps, a uterine septum or intrauterine scar tissue can be treated with hysteroscopic surgery.
Genetic Services
Most ART is done using the woman’s own eggs and her partner’s sperm. However, if there are severe problems with either the eggs or sperm,
