I have been TTC for a little over 2 years. I've been through multiple IUI's one cycle of IVF, tried acupuncture, herbal teas, etc I feel like I have been through it all and husband and I are on a break from IVF for 6 or so months. So, we are trying on our own. I figured anything I can do to aid in the process, and it's probably a long shot, but I ordered preseed and now we are in the 2ww. Hoping and praying...
Has anyone had positive luck with it?
Re: Preseed...any luck?
I have used it....but obviously with no luck. I liked it, but it will never work in my situation. We still have 2 boxes left over that we use, just because!
You might want to ask this on SAIF or PAIF.
IVF #1 = BFN
FET #1 = BFN
FET #2 = BFN
IVF #2 = BFP, b/g twins lost at 20w due to partial abruption/PPROM
IVF #3 = c/p 5w2d
Long-shot Clomid/Prednisone cycle before next IVF = BFP, our beautiful, healthy girl born 6/26/13!

TTC again March 2014
FET #3 - May/June 2014 - all embryos arrested before xfer - back to the drawing board...
IVF #4 - July/August 2014
Ditto.
The idea behind it is that normal lubes aren't sperm friendly. Some women claim that it takes the place of fertile cervical mucus, allowing sperm to live longer when they lack their own mucus. I hope this doesn't come across the wrong way, but if you've done IUIs and IVF, those procedures bypass the need for cervical mucus at all. So that's likely not the issue. Hoping you get a nice surprise.

Ditto! I've used it for a year with no luck, but I do think it's better than normal lubricant. Even if we weren't ttc, I'd probably still use it because I like it!
We use it too...
no such luck yet, but I just think of it as lube that we enjoy. Who knows if it really has any fertility benefits, but hopefully it can't hurt.

this exactly!
We had success back in October but unfortunately had a m/c. We haven't replenished our stock since, figured we'd wait a cycle or so and maybe reinvest if needed.
While it may have helped us, DH did not care for the product - felt it was too sticky.
