Summarize:

Fertility medication is perhaps the least invasive way to treat infertility. Most fertility medicines are designed to stimulate ovulation. However, there are also some medications that can help increase sperm count. There are different medications available depending on the cause of your infertility.  For instance, clomiphene (Clomid) may act as a selective estrogen receptor modulator (SERM), which can help with ovulation. Additionally, Metformin may help you get pregnant if you have polycystic ovary syndrome (PCOS). If your doctor has not identified the cause of your infertility, medications likely won't be effective. Intrauterine insemination, also called artificial insemination, is typically used if you are unable to have vaginal sex or have a condition that makes it unsafe to have unprotected sex. In some areas, you may have to wait months if not years to have access to this treatment. Additionally, not all health insurance covers the cost of intrauterine insemination. With in vitro fertilization, an egg is removed from the ovaries and fertilized with sperm in a lab, then replaced into the womb. In vitro fertilization may help if your partner has a low sperm count.  The sperm used may be your partner's, but it can also be sperm from a donor. If your partner isn't producing any sperm, a donor may be your only option. In vitro fertilization is also used in situations where you have a condition that prevents natural fertilization of the egg. If your doctor informs you that your eggs or sperm are so damaged that you are unlikely to conceive, you may need to replace them with a donor. The egg is fertilized through in vitro fertilization, then placed in the womb to grow. Surrogates are often used for infertile couples if the uterus is damaged in such a way that the fetus will not attach. This may be the case if you've had miscarriages in the past.
Take medications to enhance fertility. Have sperm inserted into the womb through intrauterine insemination. Try in vitro fertilization if intrauterine insemination doesn't work. Consider using a sperm or egg donor if sperm or egg cells are causing infertility.
