Well not personally (although I have gained alot of weight through my 3 cycles, about 5-8kg per cycle)
but a very good friend of mine was 140 when she started ivf. They had 4 cycles with no success so which was most likely due to her weight so her GP put her on reductil. She walked 3x per week and ate healthy. Within 7 months she lost 45kg. On the 5 cycle (after losing the weight) bang. Pregnant.

She has now lost another 20 kg from breastfeeding and looks FANTASTIC.

Hugs hon,

Sammie
