We had multiple tests ahead of starting IVF and our fertility consultant recommended this brand (Impryl) specifically as it contained extra ingredients that the standard pre-conception pills you can get at Boots can provide.
Having purchased Impryl for 3 months ahead of the first IVF cycle we waited in anticipation to see if movement and the number improved.
When the sperm sample was taken during the treatment cycle, the ICSI process was able to fertilise 11 eggs and we got 8 high-quality embryos to then transfer so I would recommend it to anyone worth the extra money as there are targeted beneficial ingredients.
