I have a 1.9cm low density fibroid in the left uterine body. is this something that could effect fertility. i am 39 and healthy otherwise.

Probably not: If the 1.9 cm fibroid is "intramural or subserosal" and therefore is not submucosal or extending into your endometrial lining, the possibility that it could affect affect your fertility is quite small. A Reproductive Endocrinologist and Infertility specialist may offer you a better assessment of your chances based on your age, ovulation pattern, tubal anatomy, overall health, his sperm count etc..
