Introduction
- Infertility is the inability to conceive after 12 months of regular, unprotected intercourse.
- It affects both men and women and can result from a range of physical, hormonal, or environmental factors.
- Management includes diagnosing underlying causes, providing targeted treatments, and exploring assisted reproductive technologies (ART).
Types of Infertility
- Primary Infertility
- Inability to conceive for the first time.
- Secondary Infertility
- Difficulty conceiving after a previous successful pregnancy.
Causes of Infertility
- In Women
- Ovulatory Disorders: Polycystic Ovary Syndrome (PCOS), hypothalamic dysfunction, premature ovarian failure.
- Uterine or Cervical Factors: Fibroids, polyps, or cervical stenosis.
- Tubal Factors: Blocked or damaged fallopian tubes, often due to pelvic inflammatory disease or endometriosis.
- Age: Fertility declines significantly after age 35.
- In Men
- Sperm Abnormalities: Low sperm count, poor motility, or abnormal morphology.
- Hormonal Imbalances: Hypogonadism or testosterone deficiency.
- Structural Issues: Varicocele, blockages in the reproductive tract.
- Both Genders
- Lifestyle Factors: Smoking, alcohol, obesity, or stress.
- Environmental Factors: Exposure to toxins or radiation.
Symptoms of Infertility
- In Women
- Irregular or absent menstrual cycles.
- Painful periods or pelvic pain (associated with endometriosis).
- History of miscarriages.
- In Men
- Difficulty in maintaining erections or ejaculation.
- Reduced sexual drive.
- Pain, swelling, or lumps in the testicles.
Complications of Infertility
- Emotional Impact: Depression, anxiety, and relationship stress.
- Social Stigma: Particularly in cultures where childbearing is highly valued.
- Health Risks: Underlying conditions such as PCOS or thyroid disorders may have broader health implications.
Diagnosis of Infertility
- For Women
- Ovulation Tests: Measure luteinizing hormone (LH) levels.
- Ultrasound: Evaluates ovarian reserves and detects uterine abnormalities.
- Hysterosalpingography (HSG): Assesses fallopian tube patency.
- Blood Tests: Check hormone levels (FSH, LH, estradiol, AMH, thyroid hormones).
- For Men
- Semen Analysis: Evaluates sperm count, motility, and morphology.
- Hormonal Testing: Assesses testosterone and gonadotropin levels.
- Scrotal Ultrasound: Detects structural abnormalities like varicocele.
- For Both
- Genetic testing for inherited conditions.
- Comprehensive medical history and lifestyle assessment.
Treatment Options for Infertility
1. Medications
Drug Class | Example | Brand Name | Manufacturer | Cost Range |
---|---|---|---|---|
Ovulation Inducers | Clomiphene Citrate | Clomid | Sanofi | $20–$50 per cycle |
Letrozole | Femara | Novartis | $50–$150 per cycle | |
Hormonal Treatments | Human Chorionic Gonadotropin (hCG) | Ovidrel | Merck | $100–$200 per dose |
Gonadotropins | Menopur | Ferring Pharmaceuticals | $300–$500 per cycle | |
Medications for Men | Testosterone Therapy | AndroGel | AbbVie | $300–$500 per month |
2. Assisted Reproductive Technologies (ART)
- Intrauterine Insemination (IUI)
- Sperm is placed directly into the uterus during ovulation.
- In Vitro Fertilization (IVF)
- Eggs are retrieved, fertilized in a lab, and implanted into the uterus.
- Intracytoplasmic Sperm Injection (ICSI)
- Single sperm is injected into an egg; used in severe male infertility cases.
Procedure | Cost Range |
---|---|
Intrauterine Insemination | $300–$1,000 per cycle |
In Vitro Fertilization | $10,000–$15,000 per cycle |
Intracytoplasmic Sperm Injection | $1,500–$2,000 per procedure |
3. Surgical Treatments
- For Women
- Laparoscopy or hysteroscopy to remove fibroids, endometriosis, or adhesions.
- For Men
- Varicocele repair or surgical sperm retrieval.
4. Lifestyle Modifications
- Healthy Diet: Focus on balanced nutrition with sufficient vitamins and antioxidants.
- Exercise: Maintain a healthy weight; both obesity and being underweight affect fertility.
- Stress Reduction: Yoga, meditation, or counseling can improve outcomes.
- Avoid Toxins: Minimize exposure to pesticides, heavy metals, and radiation.
Monitoring Parameters
- Track ovulation patterns and menstrual cycles in women.
- Regular semen analysis in men during treatment.
- Evaluate the effectiveness of medications or ART cycles.
Patient Counseling Points
- Discuss realistic expectations regarding success rates of treatments.
- Emphasize the importance of timely interventions, especially for women over 35.
- Encourage emotional support through counseling or support groups.
- Provide information on adoption or surrogacy as alternative options.
Use in Children
- Not applicable, but early intervention for congenital conditions may preserve future fertility.
Use in Pregnancy
- If successful conception occurs, close monitoring is required, especially in high-risk cases like multiple pregnancies from ART.
Use in Elderly
- Less relevant; treatment options may be limited for age-related infertility.
FAQs About Infertility

Q2: Can infertility be treated?
- Yes, with medications, ART, or surgery, depending on the cause.
Q3: How is infertility diagnosed?
- Through hormone tests, ultrasounds, semen analysis, and imaging studies.
Q4: What are the success rates of IVF?
- Success rates vary but average 40% per cycle for women under 35.
Q5: Does age affect infertility?
- Yes, fertility declines significantly after age 35 in women.
Q6: Is infertility common?
- It affects about 10–15% of couples globally.
Q7: Can lifestyle changes improve fertility?
- Yes, healthy eating, weight management, and stress reduction can help.
Q8: Are there risks with fertility treatments?
- Multiple pregnancies, ovarian hyperstimulation syndrome (OHSS), and emotional stress.
Q9: Can infertility be prevented?
- Not all causes are preventable, but avoiding smoking, excessive alcohol, and maintaining a healthy weight can reduce risk.
Q10: How long should a couple try before seeking help?
- After 12 months of trying, or 6 months for women over 35.
