Female Infertility
What is Female Infertility?
Female infertility means a woman has trouble getting pregnant or staying pregnant after trying for 12 months or more. For women over 35, doctors define it as 6 months of trying without success. This condition affects about 1 in 8 couples in the United States.
Infertility is not just one problem. It can result from issues with egg production, hormone balance, reproductive organs, or a combination of factors. Some women have conditions that prevent eggs from releasing each month. Others may have blocked fallopian tubes or problems with the uterus lining. Hormonal imbalances often play a central role in fertility challenges.
The good news is that many causes of female infertility can be identified through blood testing and imaging. Understanding your hormone levels gives you and your doctor a clear starting point. Early testing helps you make informed decisions about family planning and treatment options.
Symptoms
- Irregular periods or cycles that vary by more than 7 days each month
- Absent periods for several months or complete loss of menstruation
- Very painful periods with severe cramping
- Heavy menstrual bleeding that soaks through pads or tampons quickly
- Pain during intercourse
- Unusual hair growth on the face or body
- Acne or oily skin that worsens suddenly
- Unexplained weight gain or difficulty losing weight
- Milky discharge from nipples when not breastfeeding
Many women with infertility have no obvious symptoms beyond difficulty conceiving. Regular cycles do not always mean normal ovulation is happening. Blood tests can reveal hormonal issues even when periods seem normal.

Causes and risk factors
Infertility in women has many possible causes. Ovulation disorders account for about 25% of cases. Conditions like polycystic ovary syndrome cause irregular egg release. Diminished ovarian reserve means fewer eggs remain available as women age. Premature ovarian insufficiency occurs when ovaries stop working normally before age 40. High prolactin levels can suppress ovulation by blocking the hormones needed for egg development. Thyroid problems and extreme weight changes also disrupt the delicate hormone balance required for fertility.
Structural problems cause another large portion of infertility cases. Blocked or damaged fallopian tubes prevent sperm from reaching the egg. Endometriosis creates tissue growth outside the uterus that can affect fertility. Uterine fibroids or polyps may interfere with implantation. Age is the most significant risk factor because egg quality and quantity decline after 35. Other risk factors include smoking, excessive alcohol use, high stress levels, and exposure to environmental toxins. Being significantly underweight or overweight can also impact hormone production and ovulation.
How it's diagnosed
Diagnosing female infertility starts with a detailed medical history and physical exam. Your doctor will ask about your menstrual cycles, past pregnancies, surgeries, medications, and lifestyle factors. Blood tests are essential for measuring hormone levels that control ovulation and egg development. Key tests include FSH on cycle day 3 to assess ovarian reserve, AMH to predict fertility potential, and prolactin to check for hormonal imbalances that block ovulation.
Rite Aid offers testing for FSH, AMH, and prolactin through our nationwide Quest Diagnostics lab network. These tests give you critical information about your reproductive health and help identify treatable causes of infertility. Additional testing may include imaging of the uterus and fallopian tubes, ovulation tracking, or specialized tests ordered by a fertility specialist.
Treatment options
- Lifestyle changes including reaching a healthy weight through balanced nutrition and regular movement
- Reducing stress through mindfulness practices, counseling, or support groups
- Quitting smoking and limiting alcohol and caffeine intake
- Tracking ovulation using basal body temperature or ovulation predictor kits
- Fertility medications like clomiphene or letrozole to stimulate ovulation
- Metformin for women with PCOS to improve insulin sensitivity and hormone balance
- Bromocriptine or cabergoline to lower elevated prolactin levels
- Thyroid medication if thyroid dysfunction is contributing to infertility
- Intrauterine insemination placing sperm directly into the uterus during ovulation
- In vitro fertilization for more complex cases or when other treatments fail
- Surgery to remove fibroids, polyps, or endometriosis tissue
- Addressing underlying conditions like celiac disease or autoimmune disorders

Frequently asked questions
If you are under 35, try for 12 months before seeing a doctor. Women 35 and older should seek help after 6 months of trying. If you have irregular periods, known reproductive issues, or are over 40, talk to a doctor right away. Early testing can identify treatable problems and save valuable time.
Key blood tests include FSH on cycle day 3 to measure ovarian reserve, AMH to assess egg supply, and prolactin to check for hormonal blocks to ovulation. Thyroid hormones, testosterone, and other hormone levels may also be tested. These tests reveal whether hormonal imbalances are preventing conception and guide treatment decisions.
Yes, irregular periods often signal ovulation problems that make conception difficult. When cycles vary widely or periods stop completely, eggs may not release regularly. Conditions like PCOS, thyroid disorders, and high prolactin commonly cause both irregular periods and infertility. Blood testing can identify the underlying hormone imbalance.
High FSH levels above 10 to 15 IU/L on cycle day 3 suggest diminished ovarian reserve. This means fewer eggs remain available and fertility potential is reduced. FSH rises as the ovaries work harder to produce eggs. While this makes natural conception more challenging, many treatment options still exist.
AMH measures the number of eggs remaining in your ovaries. Higher AMH suggests good ovarian reserve, while low AMH indicates fewer eggs available. This test helps predict how you might respond to fertility treatments. AMH levels naturally decline with age but can also drop early due to certain conditions.
Elevated prolactin blocks the release of hormones needed for ovulation. This causes irregular or absent periods and prevents egg development. High prolactin can result from stress, certain medications, pituitary tumors, or thyroid problems. Treating the underlying cause usually restores normal prolactin and improves fertility.
Yes, lifestyle changes can significantly impact fertility for many women. Reaching a healthy weight improves hormone balance and ovulation regularity. Quitting smoking, reducing alcohol, managing stress, and eating a nutrient-dense diet all support reproductive health. While lifestyle changes may not fix structural problems, they create the best foundation for conception.
IVF may be needed when fallopian tubes are blocked, endometriosis is severe, or other treatments have not worked. It is also common for women with very low ovarian reserve or unexplained infertility after other attempts. Your doctor will recommend IVF based on your specific diagnosis, age, and how long you have been trying.
Age is the single biggest factor affecting female fertility. Egg quality and quantity decline significantly after 35 and even more rapidly after 40. This makes conception harder and increases miscarriage risk. Testing your hormone levels gives you information to make informed decisions about timing and family planning.
No, many causes of infertility are treatable. Ovulation problems often respond well to medication or lifestyle changes. Surgery can correct structural issues like fibroids or blocked tubes. Even diminished ovarian reserve does not mean pregnancy is impossible. Early testing and proper treatment give you the best chance of success.
