No, there is no scientifically proven incompatibility that would prevent a specific man and woman from conceiving together.
While some couples may struggle to conceive for years, then separate and successfully have children with new partners, this does not indicate an incompatibility. Instead, it likely reflects differences in fertility between partners, better reproductive timing, or other biological and lifestyle factors that favor conception in the new relationship.
