What should I do??

I founded out I have PCOS about 2 years ago. My fiance and I have been together for 7 years, I have a daughter. We have been TTC for 5 years to have a child. I'm taken all my meds to help alone the way. I've had cysts ruptured and they are painful. At my last appointment my OB/GYN told me to have him get his semen tested. My fiance drinks and smokes everyday. I have ask him constantly to go have his sperm tested, it won't take no more than 5-10 mins. He refuses and think it's me because I have PCOS. I'm getting so tired of doing this on my own. He want his own kids but his actions is not showing me anything. I was talking to my mother about just stopping the meds and explain to her it takes more than one person to have a child. I'm not get younger and he's not either. He over heard me talking to her about it and him. It's not like it was bad or I wasn't hiding the fact I'm frustrated with his prolonging. He's in his feelings about it now. I don't want the cysts to get worse by me stopping my meds and I still really want to have more kids, it's so heartbreaking to keep going through this. What should I do????
