Male infertility is a factor in approximately half of all cases of infertility, and the process for testing for it is easy and routine, states the American Pregnancy Association. There are at-home tests for men interested in undergoing a semen analysis, as well as specialists for both men and women to determine the cause for infertility. Gauging the reasons behind female infertility can involve multiple steps and extensive testing.
To test for male fertility in a clinic, sperm is collected in a specimen jar and then observed under a microscope, explains the American Pregnancy Association. The lab technician assesses the shape, appearance, number and mobility of sperm. If the sperm concentration is below 20 million sperm cells per milliliter of ejaculation fluid, a doctor often tests testosterone levels in the blood, in addition to LH, FSH and prolactin levels. Urinalysis may also take place.
Female fertility tests begin with evaluating whether ovulation occurs, according to the American Pregnancy Association. Women can use temperature charts, ultrasound, blood tests and ovulation predictor kits to determine ovulation. Ovarian function tests follow through the measurement of follicle-stimulating hormones, estrogen levels and the amount of inhibin B. Luteal phase testing evaluates progesterone levels with the possibility of a endometrial biopsy included.
If previous results don't point to a cause of infertility, additional tests include laparoscopy, hysterosalpingogram, endometrial biopsy and hysteroscopy, states the American Pregnancy Association.
