Hi BelovedK, Dhea has been found to increase the quality of eggs in older women. It has also helped with unexplained infertility. Google it before you try it because it does have side effects and is fairly new with being used for infertility. It shouldn't be taken while pregnant or nursing because it is a hormone(after age 40 most people have lower levels in their blood, so 50 mg is supposed to be a safe level, although I loved that VeganMama got pregnant and was on 75mg! It makes you wonder!) Maca is my new google search. I just ordered it yesterday and figured I would give it a try. It is actually a carbohydrate from a root of a plant grown in Peru and is eaten by people of Peru from childhood. It is supposed to regulate your cycle because it evens out your hormones. My dr didn't recommend hormone level testing, so I have no idea what mine are. I just figured that with all that is written about declining levels in older women, it couldn't hurt. It is also good for sperm count and mobility for men. And a host of other things like helping with depression, raising sex drive and energy. Google this, there is much info on it, but it must be ORGANIC! Mercury levels are high in those sold that are not organic. I am an impatient person(as you can see) and maybe my jumping around with supplements (vitex, some chinese herbs, dhea, now maca) isn't great because I don't give them long enough to work. I live in a very conservative area of Pa and there are no Chinese Herbalist and few accupuncturists(plus no coverage with insurance), but if you have access, they are supposed to be amazing for fertility. I have a question for all of you, how many of you still drink caffeine? I have one cup of coffee a day, should I quit?
