That's the 1 million dollars question and I'm certainly not delusional enough to think that there's a clearcut answer.
It's easy to find lots of comparison sites that strictly compare success rates of American clinics. (Are the best really in the States, btw
Even so... I'm not so much interested in success rates but more in whoever is specialized in taking hopeless cases.
In my case: male infertility.
I have severe oligospermia (<2 million count). Furthermore the motility and % of normals among these few is often below average. No genetic problem, no high DNA breaks so... not so serious, hmm? We can't get pregnant naturally but a couple of transfers should do it, right?
Well, 3 ICSIs and additionally 3 frozen transfers that failed led the doctor to say: "we're a top-notch world-class clinic and we've done everything we could do but everything failed. There's probably something in the spermatozoa that we simply cannot see! We could try this or that other technique but - truth be told - they're not going to improve your chances much further."
Heck, if we're going to give my gametes a last chance we're willing to travel to any place in the world that are objectively the best in selecting spermatozoa.
Even if you don't know which is the best clinic for me (I suppose no-one does) could you please shed me some lights?
Thanks in advance for your input.
