As many embark on the journey of marriage with dreams of a happy family, some couples face the challenge of infertility. When conception does not occur after a certain period, seeking professional consultation becomes essential. Here, we explore several key aspects of infertility.


What is Infertility?

Infertility is defined as the inability to conceive after 12 months of regular, unprotected intercourse. It is important not to make premature judgments after just a month of trying. Approximately 95% of couples succeed in conceiving within a year if they time intercourse with ovulation. However, if a woman is over 35 and has been actively trying for six months without success, consulting a specialist is advisable.


Frequency of Intercourse

Conception is possible during ovulation. For women with regular menstrual cycles, ovulation occurs approximately 14 days before the start of the next cycle. In a typical 28-day cycle, this is around the midpoint. Calculating from the first day of menstruation, understanding one's cycle is crucial for timing intercourse. Excessive intercourse near the ovulation period may actually lower chances of conception.


Factors Reducing Fertility

As maternal age increases, fertility tends to decline, often starting from the late 20s. Irregular menstrual cycles, low body weight, and previous fallopian tube surgery can significantly reduce fertility rates. Maintaining a healthy diet and regular exercise are crucial for improving fertility.


No Guarantee for Infertility Tests

While there are numerous tests providing indirect insights, conception involves a complex interplay of factors. Hormonal tests and ultrasound can ensure that bodily organs are functioning properly through blood and imaging tests.


Types of Medical Tests

  1. Pelvic or Transvaginal Ultrasound
  2. Hormonal Bloodwork
  3. Fallopian Tube Study or Hysterosalpingogram
  4. Semen Analysis


In situations where infertility or the associated stress becomes overwhelming, it is recommended to seek advice and examination from a qualified medical professional.
