Semen color and conceiving

Brandi • Mommy to the sweetest Everett Mae 🎀
My boyfriends semen is the first I can recall (compared to other sexual partners) that is almost clear. Normally guys have white semen but his is like egg white consistency and clear. I've researched it and it said it could be diet, lack of sperm, or nothing wrong at all. Has anyone else experienced this and had trouble conceiving ? Or has anyone experienced this type of semen but still conceived from it? He has gotten two other girls pregnant but this was about 5-10 years ago. He's 35 now. Any advice is appreciated! Thanks
