What Is Secondary Infertility?
Secondary infertility is defined as the inability to conceive or carry a pregnancy to term after previously giving birth. This applies whether the previous pregnancy occurred naturally or through fertility treatment. Like primary infertility, it is typically diagnosed after 12 months of trying (6 months if over 35). Secondary infertility is actually more common than primary infertility, accounting for about 50% of all infertility cases, yet it often receives less attention and support.
Why Does This Happen?
Age: Even a few years make a difference to fertility, particularly for women over 35. Egg quality and quantity decline, and the time since your last pregnancy matters.
Weight changes: Significant weight gain or loss since your last pregnancy can affect ovulation and fertility.
Hormonal changes: Conditions like PCOS or thyroid disorders may have developed or worsened since your previous pregnancy.
Sperm factors: Male fertility also declines with age, and new issues may have developed.
Scar tissue: C-sections, D&Cs, or uterine infections can cause scarring that affects implantation.
Lifestyle changes: Increased stress, different medications, or lifestyle factors may be contributing.
Underlying conditions: Endometriosis or fibroids may have progressed since your last pregnancy.
New partner: If you have a new partner, either of you may have fertility factors.
The Unique Emotional Challenge
Secondary infertility often comes with complex emotions that can feel hard to express. You may feel grateful for the child you have while grieving the family you envisioned. Others may minimise your experience with comments like at least you have one. You might feel guilty for wanting more when you already have a child. Support groups and resources for infertility may feel unwelcoming if they focus on couples without children. These feelings are valid and deserve acknowledgment. Secondary infertility is real infertility, and your pain matters.
Seeking Support and Treatment
You deserve investigation and treatment just as much as someone with primary infertility. Do not let anyone minimise your need for help.
See a fertility specialist if you are under 35 and have been trying for 12 months, or if you are 35+ and have been trying for 6 months.
Testing will be similar to primary infertility: hormone tests, semen analysis, tubal evaluation, and potentially ultrasound.
Treatment options depend on the identified cause and may include medications, IUI, or IVF.
Success rates for secondary infertility treatment are often good, particularly if the previous pregnancy occurred naturally.
Seek counselling or support groups specifically for secondary infertility if possible.
Parenting While Trying to Conceive
Balancing parenting with fertility treatment adds practical and emotional challenges. Treatment appointments, injections, and the emotional rollercoaster must be managed while caring for your existing child. Some parents feel guilty for the time and emotional energy fertility treatments require. Others worry about how to answer questions about siblings. Finding reliable childcare for appointments and giving yourself permission to have bad days are important. Your existing child can bring joy during difficult times, even as you navigate complex emotions.
