Cervical Mucus Test
This is performed to assess the probability of sperm survival, and the ability of sperm to move through the vaginal canal, cervix, and uterus.

Ultrasound Exams
Ultrasounds are painless, and performed to assess your endometrium (uterine lining), monitor follicle development (are the eggs maturing as they should be?), and assess the condition of your ovaries.

Hormone Tests
These tests are performed by drawing blood (usually about three to five tubes). Most likely, your RE will want to check the following: Luteinizing Hormone (LH), Follicle Stimulating Hormone (FSH), Estradiol, Progesterone, Prolactin, Free T3, Free Thyroxine (T4), Total Testosterone, DHEAS, and Androstenedione.
