How many DE cycles is realistic?

Anonymous
Just wondering what's realistic for how many DE cycles it may take for success with DE?

One to two max.

Took 1 but depends on where you go. Look at stats and you will see some clinics are much better than others.

Once you reach 3 or 4 transfers (not cycles, but transfers), you're theoretically close to 100% odds. I personally would try at least two cycles with different donors in case there's some as-yet-undetectable incompatibility between you & the donor or your partner & the donor.

It varies! For me, the first try worked but others I know are still trying. SG offers the six tries for one flat rate thing which seems to suggest they are pretty sure you will have success within 6 transfers. But there is always the unknown!

We did one cycle, but two transfers. (One egg retrieval - fresh transfer failed, frozen blasts resulted in kids.)

GOod luck OP.

Cycle 1: Donor's 1st donation= entire cycle sucked + BFN

Cycle 2: Repeat donor= BFP

18:54 again, technically every transfer is a new roll of the dice, but if you want to calculate cumulative odds of success, I believe it works like this (anyone out there who knows better feel free to correct my math!):

At SG, odds of clinical pregnancy for a single embryo transfer using DE VF are 60%.

So, say you have a fresh eSET, you have a 60% chance of pregnancy, with a 40% chance of a BFN.

If you did a second fresh cycle, you would calculate 60% times the 40% chance of a BFN (.60 x .40), which is 24%, and add that to the first cycle's 60%.

So for the two fresh cycles combined, your cumulative odds of success are 84%.

For a third fresh cycle, you'd calculate 60% of the remaining 16% chance of a BFN (.60 x .16), which is 9.6%, and add it to the 84%, so the cumulative odds of a clinical pregnancy over three cycles would be 93.6%.

For a fourth fresh cycle, you'd add 60% of the remaining 6.4% chance of a BFN (.60 x .064, or 3.84%), so now your cumulative odds are greater than 97%.

A fifth fresh cycle gets you close to 99%, while a 6th puts you over 99% (which is presumably why SG's money-back quarantee covers up to 6 cycles).

(Note that your cumulative odds NEVER reach 100% -- they get closer and closer to 100, but there's always a slim chance that an infinite number of cycles would still result in a BFN.)

Love this explanation! I was always doing this math in my head when I was trying, though my odds were MUCH lower!

This assumes that cycles are independent but they are not.

We've done 3: 2 abroad and 1 at SG. BFN for the two abroad / chemical (early miscarriage) at 6 weeks for the 1 at SG. All were CGH frozen embryos.

All were CGH normal embryos?

This assumes that cycles are independent but they are not.


Also assumes that recipient, egg donor, and the husband or sperm donor have no major underlying issues. I love the explanation, though - that's how it would work if everything worked reasonably well and all cycles were independent.

It worked first try for us.

Yes - all were CGH normals.

One DE cycle, resulted in ten embryos. Took three FETs though.
