Here are the most common reasons in vitro fertilization (IVF) treatments don’t work, ranging from embryos that didn’t implant to a botched transfer process.
As advanced as fertility treatments are, the specialists don’t have all the answers…
“My embryos looked perfect. My uterine lining looks great, and I did everything I was supposed to do to get pregnant, to make this in vitro fertilization work. What went wrong? Why did my IVF fail?”
Those are thoughts and questions many women struggle with, and the most common answer is, “The doctor doesn’t know.” Fertility medicine has come a long way, but infertility specialists definitely don’t have all the answers.
If you’re trying in vitro fertilization, your doctor is probably helping you determine when you ovulate. If you don’t have an ovulation predictor kit, get the babi One Step Ovulation (LH) Test Strips. They’ll help narrow down the best time to conceive a baby.
And, here are five reasons you didn’t get pregnant if you tried IVF…
Why In Vitro Fertilization Doesn’t Work
The embryos didn’t implant
“The most common reason for embryos not implanting is that their development stopped prior to reaching the implantation stage,” write Perkins and Meyers-Thompson in Infertility for Dummies. “The older you are, the more likely this is to happen, but the cessation of embryo development is thought to be the most common cause of lack of pregnancy at any age, and in fact, even during natural conception.”
A woman’s age affects her chances of getting pregnant, whether or not infertility treatments are involved.
The embryos started to implant…and then stopped
If the embryos have abnormal chromosomes, they won’t implant. “The only way to tell whether embryos have the right chromosomes is to do preimplantation genetic diagnosis (PGD), a procedure in which one cell is removed from the embryo before implantation and its DNA is analyzed for abnormalities,” write these authors.
This is an expensive medical procedure (not surprising, since all infertility and fertility treatments seem to cost a lot of money!). And it may not be worth the cost, since PGD hasn’t been shown to improve overall pregnancy rates.
The embryos were damaged, so the IVF didn’t work
Another reason the in vitro fertilization may have failed is because of damage either during the embryos’ growth in the lab or the transfer to the uterus. “Man-made processes are never going to be as effective as nature intended, and occasionally, a bad batch of medium, which is used to nurture the embryos before transfer, causes the embryo not to grow the way it should.
There is a problem with your uterus
IVF may not work if the uterine lining wasn’t healthy or ready for the implantation. Fibroids, polyps, or polycystic ovarian syndrome can make getting pregnant more difficult. According to Perkins and Meyers-Thompson, there isn’t any way to test the endometrium or uterine lining during the actual cycle because a biopsy might prevent implantation.
The embryo transfer process went poorly
If there is bleeding or cramping (or both) during the in vitro fertilization procedure, the chances of getting pregnant are decreased. If the uterus cramps, the embryos might be moved to a spot where they can’t or are less likely to implant…and the IVF will fail.
“Fertility is a numbers game, under the best of circumstances,” write the authors in Infertility For Dummies. “If doctors knew exactly why it all worked or didn’t work, they would save you and themselves a lot of time and make a lot more money, Unfortunately, medicine doesn’t have all the answers, for anything…including fertility.”
