I have been having it for 4-5 months, it can take 3 months for it to have a positive effect on egg quality etc, I did have it done during the IVF and at every appointment they kept saying how good my lining was, I don't know if it was anything to do with acupuncture but I am sure its supposed to help that too. I love it and would recommend it, its very relaxing too and my acupuncturist knows more about fertility than my GPs so I could ask her about anything and everything xx
