Many OB/GYNs received just a few weeks of infertility training during residency. Unless their medical practice is fully focused on fertility issues, a fertility specialist may be the most qualified doctor to help you overcome infertility and finally get pregnant. It is better to go for treatment with fertility expert. A fertility specialist diagnoses and treats problems better related to infertility. A fertility specialist can guide you in selecting the fertility treatment procedure that may help you carry the baby to term.
