I’m not a doctor and I don’t know anything about you, your congenital predispositions or what condition your lifestyle has left you in, but I can say that if anything natural can help it would be this…
A diet completely void of grains, vegetable oil, and sugar (basically a low carb, primal/paleo diet) abundant in healthy fats such as mono-unsaturated and saturated (loads of pastured eggs, grass-fed butter, coconut oil, avocado oil, avocados, grass-fed fatty cuts of meat), loads of non-starchy vegetables (particularly those leafy greens) and plenty of fish.
A lifestyle low in stress, high in restful sleep (that means undisturbed sleep in a very dark room, without bright lights or the use of glowing screens i.e no TV /iPad/computer/Phone within 2 hours before bed, of course it might help not to drink caffeinated drinks in the afternoons) with lots of very-low strenuous exercise (such as walking), a small amount of body-weight exercise (pull-ups, push-ups, squats and planks) and very tiny amounts of high intensity (literally a 7-10 minute session of sprint-rest-sprint-rest-sprint-rest) once every 7-10 days. No chronic cardio exercise 7 days a week!!
I don’t know if links work in this forum, here’s the link: If it doesn’t work just search YouTube for “dietdoctor fertility” and look for the interview with Michael D. Fox, M.D.
For in-depth reading on this philosophy hunt down MarksDailyApple. They have a section for success stories, they go way beyond weight loss! and I vaguely recall people conquering their PCOS problems.
Good Luck!
