Diagnostic Tests for Female Infertility:
An evaluation of a woman for infertility is appropriate for women who have not become pregnant after having 12 months of regular, unprotected intercourse. Being evaluated earlier is appropriate after six months for women who are older than age 35 or who have one of the following in their medical history or physical examination: 

•    History of irregular menstrual cycles (over 35 days apart or no periods at all)
•    Known or suspected problems with the uterus (womb), tubes, or other problems in the abdominal cavity (like endometriosis or adhesions)  
•     Known or suspected male infertility problems  

Any evaluation for infertility should be done in a focused and cost-effective way to find all relevant factors, and should include the male as well as female partners.  The least invasive methods that can detect the most common causes of infertility should be done first. The speed and extent of evaluation should consider the couple’s preferences, the woman’s age, the duration of infertility, and unique features of the medical history and physical examination.
The following tests may be recommended as part of your infertility evaluation: 

•    Male Partner Semen Analysis: Although the semen analysis is obtained from the male partner, it is an essential part of the infertility evaluation.  A semen analysis should provide information about the number, movement, and shape of the sperm. 

Tests to find out the cause of infertility in women include:
•    Blood tests to check hormone levels and ovarian reserve include:

•     1) Ovarian Reserve Testing: When attempting to test for a woman’s ovarian reserve, the clinician is trying to predict whether she can produce an egg or eggs of good quality and how well her ovaries are responding to the hormonal signals from her brain.  The most common test to evaluate ovarian reserve is a blood test for folliclestimulating hormone (FSH) drawn on cycle day 3. In addition to the FSH level, your physician may recommend other blood tests, such as estradiol, antimüllerian hormone (AMH) as well as a transvaginal ultrasound to do an antral follicle count (the number of follicles or egg sacs seen during the early part of a menstrual cycle). 

            Other blood tests:

•    2) Thyroid-stimulating hormone (TSH) and prolactin levels are useful to identify thyroid disorders and hyperprolactinemia, which may cause problems with fertility, menstrual irregularities, and miscarriages.
•     3) In women who are thought to have an increase in hirsutism (including hair on the face and/or down the middle of the chest or abdomen), blood tests for dehydroepiandrosterone sulfate (DHEAS), 17-α hydroxyprogesterone, and total testosterone should be considered.
•    4) A blood progesterone level drawn in the second half of the menstrual cycle can help document whether ovulation has occurred.  Progesterone helps the uterus grow during pregnancy and keeps it from having contractions.
•   Also, CBC and BPD Tests can be done by your primary care physician

•    Urinary Luteinizing Hormone (LH): Urinary LH testing helps define the times of greatest fertility: the day of the LH surge and the following two days.  However, these tests can be expensive and should only be used by women with menstrual cycles that are consistently 25-35 days in length.
Depending on your situation, your testing may include:
•    Hysterosalpingogram (HSG) 
•    Transvaginal Ultrasonography
•    Sonohysterography

Rarely your testing may include:
•    Hysteroscopy
•    Laparoscopy
