What Is Secondary Infertility?
Secondary infertility is the inability to conceive, or to carry a pregnancy to term, after having had one or more previous pregnancies. The same timelines apply as for a first pregnancy:
- Under 35: see a specialist after 12 months of regular unprotected intercourse
- 35 and above: see a specialist after 6 months
- Over 40, or with a known problem: see a specialist straight away
Common Causes of Secondary Infertility
1. Age
The most common reason. If your first child was born at 28 and you are now trying at 34, your egg quantity and quality have changed, even though you feel the same.
2. Complications from a previous delivery
- C-section scar defect (isthmocele): a pouch in the scar can collect fluid and affect implantation.
- Uterine adhesions: scarring after D&C, retained placenta or infection.
- Pelvic infection after delivery or miscarriage, which can damage the fallopian tubes.
3. New medical conditions
Thyroid disorders, PCOS, endometriosis, fibroids, diabetes and weight gain can all develop or worsen after a first pregnancy.
4. Male factor
Sperm quality also declines with age, smoking, stress, weight gain and illness. A man who fathered a child five years ago may have very different results today. Male factor contributes to a large share of secondary infertility cases.
5. Breastfeeding
Prolonged, frequent breastfeeding can suppress ovulation. Periods may return before regular ovulation does.
6. Lifestyle
Sleep loss, work stress and less time together as a couple are real factors for parents with a young child.
Tests for Secondary Infertility
The evaluation is similar to that for a first pregnancy, with extra attention to what has changed:
| For her | For him |
|---|---|
| AMH and hormone blood tests | Semen analysis |
| Transvaginal ultrasound (fibroids, cysts, scar defect) | Hormone tests if count is low |
| HSG or laparoscopy to check the tubes | Scrotal ultrasound if needed |
| Hysteroscopy if adhesions or scar defect suspected | |
| Thyroid, prolactin, blood sugar |
Treatment Options
Treatment depends on the cause found:
- Ovulation induction with tablets or injections for irregular ovulation
- IUI for mild male factor or unexplained cases
- Hysteroscopy or laparoscopy to repair a scar defect, remove adhesions, polyps or fibroids, or open blocked tubes
- IVF or ICSI for blocked tubes, low ovarian reserve, severe male factor or failed simpler treatments
The Emotional Side
Secondary infertility brings its own pain. Friends may say “at least you have one,” which can make you feel guilty for wanting more. Your feelings are valid. Talking openly with your partner and seeking counselling can help, and so can getting answers early rather than waiting.

Frequently Asked Questions
How common is secondary infertility?
It is about as common as primary infertility, but far less discussed.
Can a C-section cause secondary infertility?
In some women, a scar defect (isthmocele) can affect fertility. It can be diagnosed by ultrasound and treated surgically.
Should my husband get tested even though we already have a child?
Yes. Sperm quality can change a lot over a few years.
Does IVF work for secondary infertility?
IVF is effective for many causes of secondary infertility, especially blocked tubes and low ovarian reserve.
Can breastfeeding stop me from getting pregnant?
Frequent breastfeeding can delay ovulation. If you are still nursing and not conceiving, discuss it with your doctor.
