In a lot of infertility conditions, "male challenge" can be an issue. That means that men do have issues. And issues are mostly, sperm issues. This sperm issues can be due to nothing of sperm, there's nothing of volume , there's some sexual dysfunction, etc. I think these male challenges are really hard on a guy. It is really interesting how it hits us psychologically. We feel that we are not participating, we are not a bit helpful. It's kind of hard. I do want to tell the guys that, "You know, a lot of times, it's not because you're sick. A lot of times, there may be some past issue, there may be some genetic issues that it's not always necessarily, your "fault." So first of all, don't always think that there's something seriously, seriously wrong with you. But do go see a reproductive medicine professional. And most likely, it is some of the things that can be remedied. There's things that you can do. There's treatments that you can do. In Chinese medicine, there's a lot of treatment for sperm issues. In fact, we have a wide variety of sperm issues. In maturity of time, what we call ["sufertal,"] that means that your sperm is not so strong. That can be strengthened in a lot of times. That's literally, 80 - 90 % effective. Now when you do Chinese medicine, it works really, really well. Obviously, if you don't have any sperm, that would be what we call azospermia. That is a situation that can be a lot of harder. Those are situations that they're trying to retrieve a sperm from your testicle or possibly, go into a donor sperm issue. But regardless, I think it's very important not to panic at the beginning and really understand that this may not be, in fact, frequently is not necessarily a health issue. But it's important to seek a professional who can really help you, because that male challenge is a big part of trying to have or getting pregnant. It's is a very important aspect.
