A friend of mine had a long term fight with infertility. It was about 3 extremely painful years to be precise. The first year of marriage was fun, as they both enjoyed the feeling you get as newlyweds. However during the second year, it became quite gloomy as her thoughts drifted to their lack of children.

At a point of desperation, she came to me, to discuss the issue. My advice to her was to first seek counsel with a gynecologist, about the problem. Both she and her husband did as I suggested, and the confirmation received from the gynecologist, was a good one.
Since they both now knew they could have kids, they wanted to know how to improve their chances of conception. I provided her with the following advice, which she applied immediately:

1.I inquired on how she went about planning for conception, and she told me they made love randomly. I then told her, that there where days within her monthly cycle best for conception, and she would be well served targeting those days.

2.I also had to be frank with my friend regarding her weight. She was certainly not what you would class as obese. Yet, she did have a few pounds that needed to be taken care of. I told her carrying extra weight was one of the biggest impediments to getting pregnant. She took my advice with grace, and began to work on her weight.

3.I also found out that she was heavily addicted to caffeine. On several occasions, I would watch her gulp down strong cups of coffee within minutes. I advised her that research found the intake of caffeine, to be unhelpful to women looking to get pregnant. She was quite taken aback, as she was not aware of the detrimental effect of her habit to her plans for getting pregnant. There and then she decided to reduce her intake of coffee, to the bear accepted minimum.

To cut a long story short, after making the required changes, she took in about six months later. She is now blessed with a lovely baby boy, and her marriage is still rock solid.
