There are so many things a woman can do to try and help the process move along. However, there are actually many steps men can take to overcome fertility problems; you don't have to sit back and watch everything unfold while doing nothing.
First, it's always extremely important to support the woman in your life in any way you possibly can. Not only is this a potentially stressful time for you, but it can also be even more upsetting to a woman who has always dreamed of motherhood. When a couple is unable to conceive, many women struggle with feelings of worthlessness, and it's important for their partners to show them that this isn't true. Some women turn to IVF procedures or other fertility options, but these treatments can be physically and mentally draining too. About 7.4 million women have received fertility services in their lifetime, but not all of them benefited from the support of a loving partner. If you are fully there to support your wife, girlfriend, or significant other during this difficult time, they will feel a lot better about the situation. Talk to them and tell them that you are there for them no matter what.
Next, it's important to rule out all possible sources of infertility. In short, you need to make sure you aren't the problem. Before considering services such as IVF treatment, it's important to visit your physician. Many men will take the time to visit a fertility clinic to get their sperm count tested and to see if there is a potential issue with their reproductive system. Some men may even choose to try and increase “mobility” by quitting caffeine and making other lifestyle changes. Talk with your doctor about things you can cut out of your life or introduce into your life to potentially help with any issues.
Finally, if you both find out that there's nothing that can be done to naturally reproduce, it's important to accept it and choose an alternative. Some women are just not able to get pregnant, despite numerous efforts. If that is a situation you find yourself in, talk to your significant other about adopting, artificial insemination, or using a surrogate. Even if you can't naturally conceive a child, that doesn't mean you have to give up on your hopes of being a parent. There are so many alternatives out there, and one failure doesn't mean your dreams of parenthood are finished for good.
Having issues trying to reproduce can be discouraging both mentally, physically, and even spiritually. But, as a man, if you take the steps listed above to potentially further the process or support your significant other, you will both be better off as a result.
