Secondary Infertility: Causes and Coping Strategies

Is it harder to conceive with your second child? It can be but it’s different for everyone. Unfortunately, infertility affects 1 in 6 people, so if you are struggling, you’re not alone. This article will share everything you need to know about what secondary fertility is, what causes it, and the treatment options available to you. Quick facts: What is secondary infertility? Secondary infertility is when you are having difficulty conceiving after previously conceiving and giving birth. To be defined as secondary infertility, the previous birth must have occurred without help from fertility treatments or medications like IVF (in-vitro fertilisation). The definition of primary infertility, in comparison, is when someone who’s never conceived a child has difficulty conceiving. So, how common is secondary infertility? Struggling to conceive might come as a shock if you’ve already had a baby. Secondary infertility, however, is a challenge faced by lots of individuals and couples who are trying for more children.  A World Health Organization (WHO) report suggests that around 1 in 6 (17.5%) people are affected by infertility (primary and secondary infertility) worldwide. Secondary infertility: definition and signs You can be diagnosed with secondary infertility by a healthcare professional when: The main sign of secondary infertility is being unable to get pregnant when you’re having regular, unprotected sex for up to six months or a year depending on your age. It could also include several failed artificial insemination (IUI) attempts.  If you’re worried about your fertility, discuss it with your GP or a healthcare professional. Common causes of secondary infertility The causes of secondary infertility are the same as the causes of primary infertility. For women and those assigned female-at-birth (AFAB), these include age-related fertility decline, hormonal imbalances, blockages in your reproductive environment (uterus, fallopian tubes or ovaries) and lifestyle choices such as your weight, nutrition, sleep, stress, and smoking and alcohol. For males and those assigned male-at-birth (AMAB), the causes of secondary infertility are similar. These include age-related fertility decline, lifestyle choices, and hormone imbalances. However, specific concerns for males and those AMAB are testicular damage, genital infections, or problems with ejaculation or sperm. Age-related causes of secondary infertility Age-related fertility decline could be a cause of secondary fertility. For women and those AFAB, it’s natural for the quantity (ovarian reserve) and quality of eggs to diminish, leading to a decline in fertility. In your 20s, your fertility peaks. Then, fertility gradually declines in your 30s, particularly after age 35.he chances of getting pregnant each month during your 30s are about 20%. That means that for every 100 fertile 30-year-old women trying to get pregnant in one cycle, 20 will be successful and the other 80 will have to try again.  By age 40, the chance is less than 5% per cycle, so fewer than five out of every 100 women are expected to be successful each month. Advanced maternal age is associated with increased risks of infertility and complications during pregnancy. Factors like decreased ovarian reserve and higher rates of chromosomal abnormalities can contribute to challenges in conception. Hormonal imbalances affecting secondary infertility Hormonal imbalances are a leading cause of primary and secondary infertility. Hormones regulate your menstrual cycle—consider them the orchestrators of your fertility. Hormonal imbalances can indicate conditions like polycystic ovary syndrome (PCOS) or thyroid issues and can affect ovulation, meaning you might not release an egg every month or the release may be delayed. If an egg isn’t released, pregnancy can’t occur. Hormonal changes can also negatively affect male fertility, reducing sperm production, mobility and motility.  Infections and STIs affecting secondary infertility Infections, both viral and bacterial, can affect your fertility. Some infections, particularly Sexually transmitted infections (STIs), can have lasting negative effects on your fertility if left untreated so it’s important to get regular checkups. Other viral and bacterial infections might temporarily affect fertility. For male secondary infertility, the testis are particularly susceptible to viral infection. Evidence is also emerging that Covid-19 might impact the testis. A common cause of secondary infertility in males or those AMAB, is poor semen quality, including a low sperm count, and low motility. This means sperm that isn’t moving properly or abnormally-shaped sperm which makes it harder for them to move and fertilise an egg. There’s a male fertility misconception that the type of underwear someone wears can affect fertility. Although there seems to be a link between increased temperature of the scrotum and reduced semen quality, there’s no evidence to suggest that the type of underwear worn by men and those AMAB can affect infertility. If you’ve had any infections, surgeries or medical diagnoses in the last 12 months, it might be worth mentioning to your GP if you’re having trouble conceiving or with secondary infertility. Medical diagnoses and treatments affecting secondary infertility Unfortunately, cancer treatments like radiation and chemotherapy, surgery, or a medical diagnosis can affect secondary infertility. If you’ve recently undergone cancer treatment or are about to, you might want to check your fertility with a hormone and fertility test and consider fertility preservation treatments like egg freezing, IVF (in-vitro fertilisation), and donor eggs or embryos. Lifestyle considerations for secondary infertility Lifestyle choices can affect secondary infertility. Things like being underweight or overweight, smoking, using drugs and drinking alcohol. These can all increase the risk of secondary infertility by disrupting your hormone balance and impacting your overall health and well-being. Poor nutrition can negatively impact fertility Poor nutrition like eating lots of trans fats and saturated fats found in ultra-processed foods, and having a high-sugar diet have been shown to negatively impact fertility. Regular exercise to support fertility Although regular physical exercise is considered healthy and will support weight management and optimise fertility, excessive exercise can negatively affect ovulation and fertility in women and those AFAB. Getting enough sleep to support fertility Studies suggest that sleep disturbances correlate with adverse reproductive health outcomes like menstrual irregularities, increased time to and reduced rates of conception, and increased miscarriages. Women with diminished ovarian reserve were found to be 30 […]
