You Are Not Alone

About 11% of women and 9% of men of reproductive age have had fertility issues. 

There are a number of tests used to evaluate the remaining egg supply, but none of them by themselves are perfect. To gain a complete picture, Drs. Kalan and Winkler often use a combination of blood tests and ultrasound to estimate egg reserves. Tests that help us understand ovarian reserve include:

Follicle-Stimulating Hormone (FSH)

This hormone stimulates the growth of eggs in the ovaries, rising and falling with each menstrual cycle. By assessing the levels of FSH on day three of a woman's menstrual cycle, we can better determine fertility and make some initial predictions regarding future fertility treatments.

Estradiol (E2)

Estradiol (E2) is another fertility indicator that, when compared to FSH, helps Drs. Kalan and Winkler better understand your ovarian reserve and help guide our next steps.

AMH (Anti-Müllerian Hormone) 

Measuring anti-mullerian hormone (AMH) gives our fertility specialists a good estimate of how many eggs are in the ovarian reserve. However, it can't tell us about the quality or genetic health of the eggs.

Inhibin B

Inhibin B offers another indication of the number of follicles within the ovaries that can mature and become eggs. As you age, you have fewer viable follicles that can produce eggs. Assessing inhibin B can help us judge the remaining fertility.

Antral Follicle Count (AFC)

Another method to determine fertility is an antral follicle count (AFC). Unlike the blood tests mentioned above, this test uses a transvaginal ultrasound to count the number of follicles within each ovary. The more follicles present, the greater the ovarian reserve.

There are a number of tests that help us assess the uterus and fallopian tubes. For example, we will likely test ovulation to determine if you release an egg each month and if there is clear passage through the fallopian tubes. Depending on your history and symptoms, some of the fertility tests we may schedule include:

Hysterosalpingograms (HSG)

Hysterosalpingograms (HSG) is a radiological procedure in which a special dye is injected into the uterus and fallopian tubes while X-ray images are taken. The path of the dye illustrates if the inside contour of the uterus is smooth and if the fallopian tubes are open so that during ovulation, the egg can travel into the fallopian tubes and then to the uterus.


A hydrosonogram, which is also called a saline infusion sonogram (SIS), is an ultrasound procedure in which sterile water is injected into the uterus during an ultrasound. This allows our doctors to determine if there are abnormalities in the uterus. If needed, the fallopian tubes can also be evaluated.


A hysteroscopy is a minor surgical procedure in which a small camera is inserted into the uterus to directly evaluate the endometrial lining. If any abnormalities are seen, Drs. Kalan and Winkler can also use small instruments to repair the lining at the same time.  We may also combine a hysteroscopy with a laparoscopy. This allows us to insert a small camera into the abdominal cavity and evaluate the fallopian tubes.

While sperm tests are common, there can be significant variation in the results of semen analysis from one lab to another. Drs. Kalan and Winkler are experts at interpreting results. In a sperm analysis, we can assess: 


The total amount of fluid that comes out during ejaculation


The sperm count or concentration


The percentage of sperm that are moving and how well they are moving


An assessment of the size, shape, and appearance of sperm

Sperm DNA Fragmentation

Assessing DNA within the sperm for damage

Drs. Kalan and Winkler keep current with breakthroughs in fertility so that they can offer patients the latest advances in this fast-moving field.

Dr. Kalan has published extensively on topics such as polycystic ovarian syndrome (PCOS) and IVF laboratory conditions, for which he won the University of Southern California’s prestigious Fellow Research Award.

Dr. Winkler has conducted cutting-edge research in the field of reproduction, focusing on the aging process of the ovary and the effect of fertility treatments on ovarian function.

If you need advanced fertility testing, they are skilled in evaluating immunologic fertility issues, PCOS, endometriosis, endometrial receptivity issues, recurrent pregnancy loss, and more.
