What is blastocyst transfer?
A blastocyst is an embryo that has developed for five to six days after fertilisation. With blastocyst transfer, embryos are cultured in the laboratory incubator to the blastocyst stage before they are transferred to the womb. At this time, one or two of the best quality blastocysts are selected and then transferred into the woman’s womb. A blastocyst must successfully attach itself to the wall of the womb for a woman to become pregnant. We at Aarush IVF & Endoscopy Centre are offering blastocyst transfer as a means of improving chances of pregnancy by transferring most suitable & likely implantable embryo into the uterus and to control twins & triplets outcomes.
What are the pros and cons of blastocyst transfer?
Blastocyst transfer can be highly successful for some groups of women, but it isn’t right for everyone and does have some drawbacks:
- Blastocyst transfer can result in a higher likelihood of becoming pregnant when compared with Day 2 or Day 3 embryo transfer in certain groups of women.
- However, if you opt for blastocyst transfer, at times you may not get any embryos that develop to the blastocyst stage.
- There may also be fewer embryos to freeze.
- If your embryos do develop to the blastocyst stage and more than one blastocyst are transferred, you are at greater risk of producing twins.
