In-Vitro Fertilization (IVF)
The initials IVF stand for in vitro fertilization, with “in vitro” being Latin for “in glass” – a reference to the glass test tubes used in the laboratory. This is where the phrase ‘test tube baby’, often used in the media, stems from.
In Vitro Fertilization, in simple language, is growing, collecting and combining eggs with sperm in the laboratory to create embryos to be transferred to a woman’s womb.
IVF treatment – in summary – involves administration of fertility drugs to stimulate your ovaries to produce a number of eggs and then, using a minor surgical procedure, we collect your eggs and place them in a culture dish (rather than a test tube) with prepared sperm, for fertilization.
One or two of the resulting embryos can then be transferred to your womb, and any suitable embryos not used in this cycle can be frozen for you to use in future.
Who needs IVF?
Following an initial consultation with one of our fertility specialists, you’ll start your agreed treatment plan. This will involve taking IVF drugs for several weeks to stimulate egg production and prepare your womb to receive the embryos.
You’ll need to visit the Clinic for scans and blood tests during this time, and we’ll monitor you closely to assess your response to the medication and decide when to proceed to egg collection.
Since your treatment plan is individual, the drug dosage and number of visits will depend on how your body responds.
Most patients can expect to attend the Clinic for up to four monitoring visits, and we’ll review your progress each time. We’ll also discuss, in detail, any potential modifications to your treatment.
Egg collection is a minor surgical procedure, carried out by one of our fertility specialists. It involves an ultrasound guided vaginal egg collection. We immediately pass the collected eggs to our on-site embryology laboratories, which are environmentally controlled.
Following the fertilization of your eggs with sperm, we can transfer one or two of the resulting embryos to your womb through a narrow catheter that’s passed through your cervix. 18 days after egg collection, you’ll be able to do a pregnancy test. If this is positive, you should attend the clinic about 20 days later for a pregnancy scan.
Pre IVF hysteroscopy- in indicated cases and those with previous IVF failures
BTEER therapy- it is to enhance the endometrial receptivity especially in recurrent implantation failures
- ICSI is when a single sperm is injected into a single egg to achieve fertilization, specially indicated in cases where sperm count is substantially low or the quality is poor or in previous IVF failures.
- Blastocyst culture is when the embryos are grown and cultured till 5 days in the laboratory, where they undergo critical developmental changes before being returned to the womb. They are more physiological and more chances to transform into a healthy baby.
- Surgical sperm retrieval is a minor surgical procedure to harvest sperm from the testicles. For more information about PESA, TESA and TESE, speak to your doctor.
- Semen sample collection can be facilitated in cases of Ejaculatory dysfunction by vibratory or electro ejaculation methods if medical means fail
