What are the success rates of IUI vs. IVF?
0:00:10.000,0:00:16.000
Dr. Simon Kipersztok, Shady Grove Fertility: The success rate for IUIs will stubbornly hover around the 8 percent,
0:00:16.000,0:00:20.000
whereas for the IVF will be in the 50 percent.
0:00:20.000,0:00:32.000
One way of trying to understand that is to ask yourself: Our success would mean 100 percent, so how many times does 8 percent fit into 100? That's about 15 times.
0:00:32.000,0:00:40.000
So, it would mean that, potentially, you could need 15 IUI cycles to get to that pregnancy.
0:00:40.000,0:00:47.000
I hope you get pregnant on the very first cycle, and some patients achieve that; about 8 percent of patients.
0:00:47.000,0:00:55.000
Whereas, with the IVF, at 50; 55 percent success rate, your probability of achieving that pregnancy, and hopefully delivering,
0:00:55.000,0:01:00.000
would be; you know, you can fit one to two IVF cycles into a hundred.
0:01:00.000,0:01:06.000
So, that would mean that within one to two cycles, you could potentially achieve that pregnancy.
0:01:06.000,0:01:13.000
There are situations where IUIs can be very effective.
0:01:13.000,0:01:25.000
For example, if there is a single woman, or a woman in a homosexual relationship, who have completely normal, regular periods
0:01:25.000,0:01:32.000
and all of the objective measurements of their fertility are normal, and all they need is what's missing: sperm,
0:01:32.000,0:01:41.000
the use of donor sperm can be very effective, because you are just replacing what is missing. OK?
0:01:41.000,0:01:46.000
Sometimes there are patients, for example, that have had a procedure in their cervix.
0:01:46.000,0:01:54.000
And, again, they have a completely normal fertility profile except for that opening of the womb that, you know,
0:01:54.000,0:02:07.000
has been narrowed by the surgical procedure, whether it is because of congenital birth or because of related to an abnormal pap smear
0:02:07.000,0:02:17.000
and cervical dysplasia, then bypassing that cervix with intrauterine insemination as an initial approach makes, definitely, a lot of sense.
0:02:17.000,0:02:25.000
But, on the other hand, if you have patients that have moderate to severe abnormalities in their sperm,
0:02:25.000,0:02:37.000
or individuals that have one tube that is blocked and the other is open, or women that are over the age of 38, 39,
0:02:37.000,0:02:49.000
the approach of intrauterine insemination very stubbornly would remain at the 5 to 8 percent per cycle.
0:02:49.000,0:02:54.000
And, you know, I look at my patients and I say, I hope they get pregnant the first cycle.
0:02:54.000,0:02:58.000
And many say, "It's me, the one that is going to get pregnant the first cycle."
0:02:58.000,0:03:08.000
But, unfortunately, and I hate to repeat it, that probability of success, study after study, center after center,
0:03:08.000,0:03:14.000
shows that that figure of 8 percent remains very stubbornly there.
0:03:14.000,0:03:18.000
So, the in vitro fertilization would be a much better approach.
