Key Differences Between Primary and Secondary Infertility

Infertility comes as a challenge for many couples trying to conceive. It can be categorized into two types- primary and secondary infertility. Know the differences between the two below.

What is Primary Infertility?

Primary infertility occurs when a couple has difficulty conceiving after at least one year of trying to get pregnant without the use of contraception despite having regular, unprotected sex. This type of infertility occurs in couples who have never been able to achieve a pregnancy.

Common Causes of Primary Infertility:

  1. Ovulation Disorders: Conditions such as Polycystic Ovary Syndrome (PCOS) or irregular periods can prevent ovulation. This can make it difficult for women to get pregnant.
  2. Blocked Fallopian Tubes: These can happen due to infections or conditions like endometriosis, which can prevent the sperm from reaching the egg.
  3. Male Factor Infertility: Issues like low sperm count or poor sperm motility can cause difficulties in conception. 
  4. Age: As women age, egg quality and quantity decrease, which can affect fertility. Male fertility also starts to decline with age, but the effects are less pronounced.
  5. Unexplained Infertility: In some cases, there is no clear reason for infertility, even after medical tests. This is known as unexplained infertility.

What is Secondary Infertility? 

Secondary infertility is the inability to get pregnant or carry a pregnancy to full term after having a successful pregnancy previously. Unlike primary infertility, couples experiencing secondary infertility have already had at least one child but face difficulty when trying to conceive again.

Causes of Secondary Infertility:

  1. Age: The chances of complications during pregnancy increase with age. This can make conception more difficult. 
  2. Changes in Reproductive Health: Conditions that develop after having a child, like endometriosis, fibroids, or pelvic infections, can interfere with future pregnancies. 
  3. Male Factor Infertility: Like primary infertility, issues with sperm count or motility can also affect a couple’s ability to conceive after previously having children. 
  4. Previous Pregnancy Complications: Complications such as miscarriages or difficult pregnancies may impact fertility, making subsequent pregnancies harder to achieve or carry to term.
  5. Lifestyle Factors: Changes in lifestyle, including weight gain, stress, smoking, or alcohol consumption, can also cause secondary infertility.
