hello, thank you for your concern. Well, infertility is worst and more than nightmares for every infertile. There are many other factors which are indirectly affecting our fertility system. Even Most women are unaware of them. I am also infertile. In the beginning, I was unaware of my infertility causes. But many doctors told me that my infertility is unexplained. But now after visiting many doctors many of my friends suggest me to opt for IVF. But still, I am very confused about it. I know in this advanced world it has become much easy for us to treat infertility. Thank you for sharing this.Its very helpful for every infertile like me to overcome this issue.
