What Are the Causes of Infertility? Insights from Iswarya Fertility Centre
Introduction
Understanding why pregnancy does not happen naturally is the first step toward effective fertility treatment. At Iswarya Fertility Centre, couples often ask, “What causes infertility?” Fertility challenges can arise due to factors in women, men, or both partners, and sometimes for reasons that are not immediately obvious. Early evaluation helps identify the cause and allows timely intervention.
Female Causes of Infertility
1. Ovulation Problems
Ovulation issues are one of the most common causes of female infertility. Conditions like Polycystic Ovary Syndrome (PCOS), hormonal imbalances, or age-related decline can prevent regular egg release.
2. Tubal or Uterine Factors
Blocked fallopian tubes, uterine abnormalities, or endometriosis can interfere with fertilization or implantation. Iswarya specialists evaluate these factors using imaging and diagnostic tests.
3. Age-Related Fertility Decline
Women’s fertility naturally declines with age, particularly after 35, due to reduced egg quantity and quality.
4. Hormonal Disorders
Thyroid issues, elevated prolactin, or other hormonal imbalances can disrupt ovulation and menstrual cycles.
5. Reproductive Tract Conditions
Endometriosis, fibroids, or pelvic inflammatory disease can create a hostile environment for conception.
Male Causes of Infertility
1. Sperm Quality Issues
Low sperm count, poor motility (movement), or abnormal shape can prevent fertilization.
2. Medical Conditions
Varicocele (enlarged veins in the testicles), infections, hormonal imbalances, or previous surgeries can affect sperm production.
3. Lifestyle Factors
Smoking, alcohol use, excessive stress, or exposure to toxins may impact sperm health.
4. Age-Related Factors
While men remain fertile longer than women, sperm quality gradually declines with age, affecting conception chances.




Combined and Unexplained Factors
Sometimes, infertility arises from a combination of male and female factors. In other cases, all tests appear normal, yet pregnancy does not occur. This is known as unexplained infertility. At Iswarya Fertility Centre, unexplained infertility is managed with personalized treatment strategies, which may include IVF or other assisted reproductive techniques.
