If you’ve been trying to conceive without success, you’re probably wondering if infertility might be the reason. The journey to parenthood doesn’t always follow a straight path, and understanding the signs your body may be sending you is the first step toward finding answers.
This guide will help you recognize potential infertility signs and symptoms, understand when it’s time to seek testing, and learn what that testing process involves.
What is Infertility?
Before diving into symptoms, let’s clarify what infertility actually means. According to the medical infertility definition, infertility is the inability to conceive after 12 months of regular, unprotected intercourse. One can adjust that definition to the inability to conceive after 6 months of fertility-focused intercourse (for couples who chart cycles and know how to target the fertile part of the cycle).
Primary vs. Secondary Infertility: Understanding the Difference
Not all infertility looks the same. You might be experiencing one of two types:
Primary infertility means you’ve never been able to get pregnant despite trying for 12 months or more.
Secondary infertility occurs when you’ve successfully had a child before but are now struggling to conceive again. This surprises many people as they assume that because pregnancy happened once, it should happen easily again. However, secondary infertility is actually quite common and can result from age-related changes, new health conditions, or shifts in hormone balance since your last pregnancy.
Signs of Infertility in Women
Your body often provides clues when something isn’t quite right with your reproductive system. While experiencing one or two of these infertility symptoms doesn’t automatically mean you’re infertile, they can indicate underlying issues worth investigating.
Menstrual Cycle Irregularities
Your menstrual cycle is like a monthly report card on your reproductive health. Watch for these signs of infertility in women:
- Irregular periods that vary significantly in length from month to month
- Heavy periods where the amount of blood flow requires frequent pad or tampon changes
- Extremely light periods or spotting instead of normal flow
- Absent periods (amenorrhea) when you’re not pregnant or breastfeeding
- Very painful periods (dysmenorrhea) that interfere with daily activities
- Cycles shorter than 21 days or longer than 35 days
- Short or variable length of the luteal phase (time after ovulation)
A healthy cycle typically runs 25-35 days. Consistency matters, if your cycle length bounces around unpredictably, it may signal hormonal imbalances affecting ovulation.
Hormonal Symptoms
Hormones orchestrate your entire reproductive system, so hormonal imbalances often show up in visible ways:
- Severe acne, especially along the jawline
- Excessive facial or body hair growth (hirsutism)
- Thinning hair on your scalp
- Unexplained weight gain or difficulty losing weight
- Persistent fatigue despite adequate sleep
- Mood swings, anxiety, or depression
- Low libido
Physical Signs
Certain physical infertility symptoms can point to conditions affecting fertility:
- Pelvic pain outside of your period
- Pain during intercourse (dyspareunia)
- Milky nipple discharge when not breastfeeding (could indicate prolactin issues)
- Changes in breast size or tenderness unrelated to your cycle
Underlying Conditions
Several health conditions are strongly associated with female infertility:
- Polycystic Ovary Syndrome (PCOS): Most common cause of ovulatory infertility
- Endometriosis: Where uterine-like tissue grows outside the uterus
- Thyroid disorders: Both hyperthyroidism and hypothyroidism affect fertility
- Premature ovarian insufficiency: When the ovaries stop working normally before age 40
- Uterine fibroids or polyps: Benign growths that can interfere with implantation
- The effect of stress: Cortisol levels that remain elevated can impact your cycle hormones
- Infection: the presence of organisms in the genital tract (even without overt signs of inflammation) can lead to inflammatory changes that will affect fertility
Signs of Infertility in Men
Male factor infertility contributes to about 40-50% of all infertility cases, yet it’s often overlooked. Men may not have as many obvious symptoms, but certain signs of infertility in men warrant attention.
Sexual Function Changes
- Difficulty maintaining an erection
- Problems with ejaculation
- Reduced sexual desire
- Pain or swelling in the testicles
Physical Indicators
- Small, firm testicles: May indicate low testosterone or sperm production issues
- Inability to smell: Can signal Kallmann syndrome, affecting hormone production
- Gynecomastia: Abnormal breast growth suggesting hormonal imbalance
- Decreased facial or body hair: Potential sign of chromosomal or hormonal issues
- Varicocele: Enlarged veins in the scrotum (often described as feeling like “a bag of worms”)
Health History Red Flags
- History of undescended testicles
- Previous groin injuries or surgeries
- Childhood illnesses like mumps affecting the testicles
- Exposure to radiation or chemotherapy
- Chronic health conditions like diabetes
- Prolonged use of certain medications (steroids, anti-androgens)
Important note: Many men with male factor infertility have no obvious symptoms at all. This is why fertility testing is so important when a couple is struggling to conceive.
Common Causes of Infertility
Understanding what might be causing infertility can help you have more informed conversations with healthcare providers.
Female Factor Infertility
The most common causes include:
- Ovulation disorders (PCOS, thyroid issues, premature ovarian insufficiency)
- Tubal factor infertility (blocked or damaged fallopian tubes)
- Endometriosis
- Uterine abnormalities (fibroids, polyps, structural issues)
- Age-related decline in egg quality and quantity
- Genetics
Male Factor Infertility
Common causes include:
- Low sperm count (oligospermia)
- Poor sperm motility (asthenozoospermia)
- Abnormal sperm morphology (teratozoospermia)
- Varicocele (enlarged veins in the scrotum)
- Hormonal imbalances
- Blockages preventing sperm release
- STDs and long-term consequences
- Genetics
Unexplained Infertility
In about 10-30% of cases, standard fertility testing doesn’t reveal an obvious cause. This is called unexplained infertility. While frustrating, it doesn’t mean nothing can be done, it often means looking deeper at factors like:
- Egg or sperm quality issues not detected by standard tests
- Implantation problems
- Immune factors
- Lifestyle and environmental factors
- Subtle hormonal imbalances
When Should You Get Tested for Infertility?
The standard recommendation is to seek fertility testing after 12 months of timed, unprotected intercourse without conception. However, you shouldn’t wait the full year if you have been using fertility-focused intercourse OR if certain risk factors are present.
Don’t Wait the Full Year If…
Seek evaluation sooner, regardless of how long you’ve been trying, if:
- You have known fertility risk factors (PCOS, endometriosis, previous pelvic surgery)
- Your partner has known fertility issues or risk factors
- You’ve experienced multiple miscarriages
- You have a history of cancer treatment
- You have irregular or absent menstrual cycles
- You’re over 35: Age-related fertility decline means earlier evaluation provides more treatment options
- Do you have any of the symptoms or conditions mentioned in the signs of infertility sections above
If you’re wondering, “Am I infertile?” and experiencing concerning symptoms, trust your instincts. There’s no harm in seeking answers sooner rather than later.
Approach to Infertility
At Couri & Smyth Health For Life, we use functional medicine to help couples achieve pregnancy by getting to the root of the problem. Rather than treating infertility symptoms, we investigate the underlying causes, which could include: hormonal imbalances, nutritional deficiencies, inflammatory and infectious conditions, and metabolic issues that may be preventing conception. We assist couples in early pregnancy to continue to troubleshoot and manage issues that could be risk factors for miscarriage.
