When a couple has been trying for a baby for months with no luck, the questions, tests and worry usually land on the woman first. Her cycle is tracked, her diet is questioned and her age is discussed. Meanwhile, the man’s health often goes unexamined, even though it plays just as big a part in whether a pregnancy happens.
Male fertility is rarely talked about openly, and many men have no idea anything might be wrong until they are tested. Understanding the health factors involved can help couples ask the right questions sooner and spend less time guessing.
Why Male Fertility Is Often Left Out of the Conversation
Fertility problems are far from a women’s issue. According to the HFEA, men are just as likely as women to have difficulty with their fertility, and for around half of heterosexual couples having problems conceiving, the cause is sperm-related.
The NHS estimates that around 1 in 7 couples may have difficulty conceiving. Problems can sit with one partner, both partners, or neither, as no clear cause is found in around a quarter of cases. This is why it makes sense to look at both partners’ health from the start rather than one at a time.
What Sperm Health Actually Means
Sperm health is about more than numbers. A semen analysis looks at three main things:
- Count: how many sperm are present. A low sperm count is defined as fewer than 15 million sperm per millilitre of semen.
- Movement: how well the sperm swim, also called motility.
- Shape: whether the sperm are formed normally, also called morphology.
A man can have a normal count but poor movement, or good movement but a high number of abnormally shaped sperm. None of this can be seen by eye, and most men feel completely well, which is one reason these issues stay hidden for so long.
Everyday Habits That Can Affect Sperm
The NHS links sperm quality to several lifestyle factors, including:
- Smoking
- Drinking more than 14 units of alcohol a week
- Being overweight
- Wearing tight underwear, which can raise the temperature of the testicles
- Recreational drugs, including anabolic steroids and cocaine
These are worth looking at, but they are only part of the picture. A man who eats well, exercises and does not smoke can still have sperm problems. Looking after stress and sleep matters too, and small daily routines that help you unwind can make the months of trying feel more manageable, even if they are not a fix in themselves.
Medical Conditions and Hormones
This is the side of male fertility that tends to get overlooked. According to nidirect, problems with sperm count and quality can be linked to hormone imbalances such as hypogonadism, genetic conditions such as Klinefelter syndrome, having had undescended testicles as a baby, and tubes that carry sperm being blocked or damaged.
Certain medicines can also play a part, including testosterone replacement therapy, long-term anabolic steroid use, chemotherapy, some antibiotics and some antidepressants. Anyone taking regular medication should speak to their GP rather than stopping it on their own.
Environmental Exposures at Work and Home
What a man is exposed to day to day can matter as well. The NHS advises avoiding workplace chemicals such as pesticides, solvents and some heavy metals where possible. Men who work in farming, manufacturing, decorating or similar trades may want to mention this to their doctor. It can also be worth taking a closer look at the products and materials you live with, and our guide to doing a health check on your home is a good place to start.
Common Misconceptions About Male Fertility
A few beliefs often stop men from getting checked:
- “I feel healthy, so I must be fine.” Most men with sperm problems have no symptoms and only find out after testing.
- “A home test kit will tell me everything.” Some kits only measure sperm count and not movement, and some use an older threshold that can give false reassurance or cause needless worry.
- “Fertility is mainly about the woman.” As the figures above show, sperm-related causes are just as common.
Why a Professional Semen Analysis Matters
A semen analysis carried out in a laboratory is the main test for male fertility. The NHS explains that if a problem is found, the test is usually repeated around three months later, and a second abnormal result leads to a specialist referral, which may include blood tests or an ultrasound scan.
The HFEA points out that the earlier sperm-related infertility is diagnosed, the sooner specialist support can be sought. Clinics such as Hull & East Riding Fertility run diagnostic semen analysis covering count, movement and shape, with results interpreted by the doctor who requested the test. Knowing where things stand means couples can talk through their options, from lifestyle changes to treatments such as ICSI, which the HFEA describes as the most common treatment for male infertility.
When to Speak to a GP
The NHS recommends seeing a GP if you have been having regular sex without contraception for over a year without conceiving, or after six months if your partner is 36 or over. If you already know of something that could affect your fertility, such as a past testicular problem or a long-term condition, it is worth going sooner.
Taking the Guesswork Out of Trying for a Baby
Months of trying without answers can be exhausting, especially when only one partner is being looked at. Male fertility is shaped by habits, medical history, hormones and surroundings, and many of these factors are easy to miss without a proper check. Bringing both partners into the conversation early, and getting a semen analysis when the time is right, gives couples clearer information and a better sense of what to do next.
