would love to hear from anyone that has used ICSI and IMSI (latter is magnetic selection of best sperm morphologically) for already good quality sperm and if they saw improved embryo quality as a result? I’m 45 and hubbie 47. He has really good sperm quality but clinics seem to be pushing this and it adds apx £2k. Really curious if anyone thinks it’s worth the cost? I’m not convinced but would love to hear.

Thoughts on ICSI and IMSI


hey! I’m not sure you will need ICSI or imsi if your husband has good sperm quality? It’s really only used if they are less quality so they can pick the best ones and give them a helping hand to get into your egg. We had ICSI because we needed to. It has worked for us, but I think in your case, you shouldn’t need to have the added cost. Let natural selection do its work with normal ivf 😊
IMSI is better from my experience as it eliminates any poor quality sperm from a sample. Icsi is not as good. IMSI will increase chances of fertilisation more than icsi in my experience. We did icsi when I was 38 and we only had 3 blastocysts and all failed. We did IMSI at 38 but nearly 39 and quality was better. I became pregnant. At 40, we did egg retrieval for second child and used IMSI and all eggs that fertilised became blastocysts. I never looked back. IMSI is better.
we used ICSI due to partners sperm morphology being 1%. Unsure if you would need it if there are no issues with your partners sperm? For us, it helped a lot. We had 7 embryos all good quality, I’m pregnant now after 3rd FET. I don’t know anything about IMSI, my clinic didn’t discuss it for us x
I imagine they are suggesting as due to his age his sperm dna may be not so good even if numbers are good. ICSI I would say is worth doing, but Zymot is much better than IMSI for sperm dna issues.
But yes always a chance not needed at all, it’s very hard to know. I guess if none of the eggs fertilise well then you’d have to pay for another egg collection which would be more than £2k. It’s all so hard to know.
We did ICSI and Zymot and that worked well for us.
