Does PCOS Cause Infertility?
Yes, simply put, PCOS causes infertility. In fact, it is the number one cause of female infertility accounting for roughly 20-25% of all cases of infertility. Fortunately, as we will learn below, there are many fertility treatments that treat PCOS caused infertility making it possible for most to get pregnant with PCOS if treated before age becomes a significant factor. In fact, due to the mechanism in which it causes infertility, it is actually one of the easier forms of infertility to treat.
How does PCOS Cause Infertility
During a normal cycle, a woman develops many follicles that contain eggs. Around day 14 of her cycle when one of the eggs is appropriately developed, a woman ovulates, or releases the egg.
Women with PCOS often develop many small, antral follicles with eggs in them, however, the eggs fail to mature properly so they are never ovulated. Most women with PCOS do not ovulate or don’t ovulate regularly. This is known as anovulation, and it makes it difficult to get pregnant without fertility treatment.
PCOS Fertility Treatment
As mentioned, PCOS is the leading cause of infertility. The good news is there is lots you can do to improve your fertility and many fertility treatment options. Before we go there, let’s briefly touch on the medications someone with PCOS encounters when trying to conceive.
Common medications used to treat PCOS:
- Letrozole (Femara): Originally developed as a breast cancer medication, letrozole is the most often the best choice to stimulate the ovaries during an ovulation induction timed intercourse cycle and IUI cycles. For those with PCOS, it works by increasing the amount of FSH the pituitary gland secretes.
- Clomiphene (Clomid): An anti-estrogen medication that is often used for timed intercourse and IUI cycles though it is rarely used at CNY Fertility as a female fertility medication. If you’re OBGYN or fertility specialist is prescribing Clomid, you may want to ask about Letrozole.
- Metformin (Glucophage, Fortamet, others): An oral medication for type two diabetes helps improve insulin resistance and lower insulin levels. Though it may not seem related to infertility, metformin has been shown to help tremendously for those with PCOS.
- Gonadotropins: Injectable medications usually encountered after failed IUIs. It can be used with both IUI and IVF cycles.
- Fertility supplements can help to improve PCOS symptoms like insulin resistance, irregular ovulation, anovulation, and embryo quality.
Common fertility treatments for those with PCOS:
Ovulation Induction with Timed Intercourse
ovulation induction is usually the first medical intervention someone that is trying to get pregnant with PCOS encounters. Ovulation induction involves taking medications (like letrozole and sometimes a trigger shot) to help stimulate ovulation. Couples are then instructed to engage in timed intercourse.
Intrauterine Insemination (IUI)
Also known as artificial insemination, IUIs typically use similar medications to ovulation induction (but can also use gonadotropins) and have the advantage of inserting the sperm inside the uterus making the journey the sperm must travel much shorter.
In Vitro Fertilization (IVF):
IVF is the gold standard of fertility medicine offering the quickest time to pregnancy per treatment cycle for anyone (including those with PCOS). The eggs are removed from the woman’s ovaries, fertilized, grown in a lab, and 3-5 days later transferred back into the woman’s uterus or frozen for a subsequent Frozen Embryo Transfer. There are many different medication protocols that go along with IVF.
While CNY Fertility Specialises in assisting reproduction, women with PCOS also have many other symptoms that are often managed by their OBGYN or other medical professionals.
