What is Infertility?
According to the World Health Organization (WHO), infertility is a disease of the male or female reproductive system characterized by the failure to achieve pregnancy after 12 months or more of regular, unprotected sexual intercourse.
It affects approximately 1 in 7 couples and is a shared concern, with causes distributed among male, female, or a combination of factors.

Details and Types
- Primary Infertility: When a person has never achieved a pregnancy.
- Secondary Infertility: When a person has achieved at least one prior pregnancy but is now unable to conceive again.
The Importance of Timing
Over 80% of couples where the woman is under 40 conceive naturally within a year. While 12 months is the standard guideline, women aged 35 or older are encouraged to seek help after 6 months due to the natural decline in egg quality.
In 10–25% of cases, the cause remains Unexplained Infertility, where standard tests show normal results.

Causes and Factors
Female Factors
- Ovulation Disorders: Such as PCOS or thyroid issues.
- Tubal Blockage: Often resulting from PID, STIs, or endometriosis.
- Uterine Abnormalities: Fibroids, polyps, or congenital issues.
- Age: Significant decline in egg quality/quantity after 35.
Male Factors
- Sperm Abnormalities: Issues with count, motility (movement), or morphology (shape).
- Functional Issues: Ejaculatory dysfunction, varicocele, or hormonal imbalances.
Lifestyle Risk Factors
Smoking, excessive alcohol consumption, obesity, chronic stress, and exposure to environmental toxins significantly impact fertility for both partners.

Diagnosis and Evaluation
The investigation process determines the functional capacity of the reproductive system through:
- Initial Consult: Medical history and lifestyle review.
- Female Testing: Hormone blood tests (FSH, AMH), transvaginal ultrasound, and HSG (to check tubal patency).
- Male Testing: Comprehensive semen analysis.
Conclusion: Infertility is not always permanent. With a correct diagnosis and timely medical intervention, many couples successfully conceive and achieve their goal of parenthood.
