When you are not able to conceive for 6 months or a year despite unprotected sex, it is termed infertility. It can be because of various reasons in both men and women. So before beginning any treatment, your doctor will first recommend a certain blood tests for infertility for both partners to find the exact cause of infertility.
Only some tests are recommended for all patients. Depending on their condition, your fertility specialist may recommend some of the following blood tests.

Follicle-stimulating hormone test is done to determine the condition of women’s egg supply. This FSH hormone helps control a woman’s menstrual cycle, egg production, and ovarian function. The blood test is done on the second and third day of the menstrual cycle to find the cause of the problem.
In Males, the production and transportation of sperm are controlled by the FSH hormone. So this FSH test in males is done to determine the sperm count.
Estradiol is a form of estrogen hormone. This hormone is responsible for sexual development and is required for estrogen production. Doctors may perform this test to know the cause of infertility. This estradiol blood test is recommended to measure ovarian function and evaluate egg quality.
This test is also recommended for missing periods, abnormal bleeding, and damage to the adrenal glands, Ovaries or testes in men.
Luteinizing Hormone Level
Pituitary gland secretes this hormone. This pituitary gland stimulates ovulation in women and the fusion of androgen in men. This hormone is essential for the functioning of ovaries in women and stimulates the testosterone hormone that affects sperm production in men.
This blood test can determine whether infertility is caused due to the failure of the ovaries or the pituitary gland.
This Luteinizing Hormone (LH) level test is done at the beginning of your cycle. This test helps determine the number of problems in women, like polycystic ovary syndrome, premature menopause, ovulation interference, or genetic conditions. In men, this LH test is done in evaluating male factor infertility.
This prolactin hormone plays an important role in milk production and is a hormone made by the pituitary gland. During pregnancy, the level of this hormone increases and inhibits ovulation after the delivery, which is why women do not get periods after delivery or when they become pregnant. But if the prolactin level increases without a pregnancy or delivery, it leads to infertility.
In women a prolactin test is done to determine why a woman is not ovulating or when a woman has symptoms like nipple discharge, etc.
In men, this prolactin test is done when there is a lack of sexual desire, difficulty in getting an erection, or a problem with the pituitary gland.
Androgen affects the sexual functioning of both men and women. An Androgen test in women is done to test its level because a high level of androgen can cause polycystic ovary syndrome, and women with PCOS do not ovulate, which results in infertility.
And in men, this test is done to know the cause of low sex drive, inability to get an erection, or infertility.
Anti-Mullerian Hormone (AMH)
AMH is a hormone secreted by the cell in the ovary and supports egg development. The doctor may recommend this because this test gives a good understanding of ovarian function and egg reserve.
If the level of AMH is lower in level, it predicts a lower egg yield and, thus, a lower chance of success in IVF.
Thyroid-Stimulating Hormone (TSH)
This test is done to check for thyroid disease among women. It can be either hypothyroidism or hyperthyroidism. Either of the conditions can cause infertility problems because of hormone imbalances.
These blood tests are done to know the cause of infertility in both men and women. A doctor may suggest some of the tests per your condition to know the cause of infertility, provide treatment accordingly, and improve your fertility health.
