Difficulty getting pregnant can involve the woman, the man, both partners or sometimes no immediately identifiable cause. Male fertility assessment—often beginning with a semen analysis—should be part of a couple's fertility evaluation.
Educational only — not medical advice. If you have urgent symptoms, seek medical care.
A couple has been trying for pregnancy.
Months pass.
The woman gets:
blood tests
ultrasounds
medications
supplements
scans
Then someone finally asks:
“Has your partner done a semen analysis?”
He has not.
This happens far too often.
Pregnancy requires both an egg and sperm.
So when pregnancy is not happening, fertility should be approached as a couple's issue, not automatically a woman's problem.
Your male partner should usually be assessed as part of the fertility evaluation, not only after every possible test has been completed on you.
A basic first test is often:
semen analysis.
It provides information about sperm production and semen quality.
Male factors contribute to a substantial proportion of couples experiencing infertility.
Sometimes the main issue is male.
Sometimes it is female.
Sometimes both partners have contributing factors.
And sometimes routine testing does not identify a clear cause.
This is why investigating only one partner can miss important information.
Pregnancy happens in the woman's body.
So socially, when pregnancy does not occur, attention often goes directly to her.
She may be asked:
“When are you giving birth?”
“Have you checked yourself?”
“What is wrong with you?”
Meanwhile, nobody asks about the man's fertility.
That is not medically appropriate.
The male partner provides sperm.
For natural conception, sperm generally need to:
be produced in sufficient numbers
move effectively
reach the egg
be capable of fertilization
Problems in any of these areas may reduce the chance of pregnancy.
A semen analysis examines a semen sample in a laboratory.
It may report features such as:
semen volume
sperm concentration
total sperm number
sperm motility
sperm morphology
other semen characteristics
It is one of the most useful initial tests when evaluating male fertility.
Sperm count refers to how many sperm are present.
You may see reports using:
sperm concentration
which refers to the number of sperm per millilitre of semen.
A lower count may reduce the chance of natural conception, depending on how low it is and what the other semen parameters show.
Motility refers to how sperm move.
Sperm need effective movement to travel through the female reproductive tract toward the egg.
Poor motility may reduce fertility.
Morphology describes sperm shape.
Laboratories assess the percentage of sperm meeting specific shape criteria.
Morphology should not usually be interpreted in isolation.
A semen analysis needs to be considered as a whole.
Not necessarily.
Semen quality can vary.
It can be influenced by:
illness
fever
collection conditions
abstinence period
medications
lifestyle
normal biological variation
An abnormal test may need to be repeated according to clinical guidance.
No.
A normal result is reassuring, but it cannot prove that pregnancy will definitely occur.
Likewise, a mildly abnormal result does not mean natural pregnancy is impossible.
Results need clinical interpretation.
The laboratory will provide instructions.
Usually, semen is collected into a sterile container after a recommended period of abstinence.
It is important to follow instructions because:
incomplete collection
incorrect storage
long delays before analysis
can affect results.
Some men feel uncomfortable about it.
That is understandable.
But it is a medical test, just like:
a blood test
urine test
ultrasound
Avoiding the test because of embarrassment can lead to months of unnecessary investigation and treatment for the woman.
If you have reached the point where fertility evaluation is indicated, male assessment should generally happen early.
For example:
after about 12 months of trying if the woman is under 35
after about 6 months if she is 35 or older
sooner if there are known risk factors
Earlier assessment is reasonable if he has a history of:
undescended testicles
testicular injury
testicular surgery
cancer treatment
genital infection
significant varicocele
erectile dysfunction
ejaculation problems
anabolic steroid use
testosterone treatment
previous infertility
A varicocele is enlargement of veins around the testicle.
Some varicoceles are associated with impaired sperm production.
But not every varicocele causes infertility or needs treatment.
Assessment depends on:
physical findings
semen results
symptoms
fertility history
Some infections can affect the reproductive tract.
Sexually transmitted infections may sometimes contribute to reproductive problems.
Other infections associated with high fever can temporarily affect sperm production.
This is one reason a man's medical history matters.
Testicles function best at a temperature slightly below core body temperature.
Repeated significant heat exposure may affect sperm production in some circumstances.
But fertility advice should remain practical.
You do not need to live in fear of every warm environment.
Smoking is associated with poorer reproductive and general health.
Men trying for pregnancy should be encouraged to stop smoking.
This benefits far more than fertility.
Heavy alcohol consumption can affect:
hormones
sexual function
overall health
Moderating or avoiding harmful alcohol use is sensible during pregnancy preparation.
Recreational drugs may affect reproductive health.
When trying to conceive, avoiding them is the safest approach.
This is extremely important.
A man may think:
“More testosterone means more masculinity, so it should mean more sperm.”
But external testosterone can actually suppress sperm production.
Prescription testosterone and anabolic steroids can reduce sperm counts dramatically and may sometimes result in no sperm being detected in semen.
He should discuss fertility plans with the clinician prescribing it.
Do not independently stop essential treatment without medical advice.
But the prescriber needs to know that pregnancy is desired.
Anabolic steroids can suppress the hormonal signals needed for normal sperm production.
Men trying for pregnancy should avoid them.
Recovery after stopping may take time.
Higher body weight can be associated with:
hormonal changes
reduced semen quality
erectile dysfunction
metabolic disease
Improving overall health may help reproductive health.
But weight is only one possible factor.
Severe undernutrition can also affect hormones and reproductive health.
Healthy fertility depends on adequate nutrition in both partners.
Diabetes can sometimes affect:
erectile function
ejaculation
hormones
general reproductive health
Good diabetes management is important before pregnancy for both partners.
The routine folic acid recommendation for neural tube defect prevention applies to the person who may become pregnant.
Men should focus on a balanced diet rather than assuming large folic acid doses will improve sperm.
Be cautious.
Products may contain combinations of:
zinc
selenium
vitamins
antioxidants
herbs
Some nutrients are important for normal health, but evidence that routine antioxidant supplement combinations improve the chance of having a baby is inconsistent.
A supplement should not replace semen analysis.
Usually not dramatically.
Sperm production is a biological process that takes several weeks to months.
This means lifestyle changes generally need time before they may be reflected in semen quality.
The next step depends on how abnormal the result is.
Evaluation may include:
repeating the semen analysis
medical history
physical examination
hormone testing
ultrasound in selected cases
genetic testing in severe cases
Treatment depends on the cause.
This is called azoospermia.
It requires specialist assessment.
Possible causes include:
blockage
impaired sperm production
hormonal problems
genetic conditions
testosterone or anabolic steroid use
Azoospermia does not always mean there are no reproductive options, but it needs proper evaluation.
Sometimes.
Treatment depends on the cause.
Options may include:
treating hormonal problems
stopping harmful medicines or steroids under medical guidance
treating selected varicoceles
addressing sexual or ejaculation problems
assisted reproductive technologies
There is no single medicine that fixes every low sperm count.
Then evaluation should continue according to the couple's situation.
A normal semen analysis does not mean:
“The problem must therefore be the woman.”
Some fertility problems remain unexplained even after both partners have standard testing.
He can still have a fertility problem now.
Fertility can change because of:
age
illness
medication
infection
surgery
lifestyle
hormonal changes
Having fathered a child before does not guarantee current fertility.
He may still need testing.
Do not assume:
“I have PCOS, so there is no reason to check him.”
Both partners can have fertility factors at the same time.
The same principle applies.
A diagnosis in the woman does not exclude a male fertility factor.
Checking both partners can prevent unnecessary delays.
A practical male preconception plan includes:
stop smoking
avoid recreational drugs
avoid anabolic steroids
discuss testosterone use with a clinician
avoid harmful alcohol use
maintain a healthy diet
exercise regularly
manage chronic disease
seek treatment for persistent erectile or ejaculation problems
These support overall reproductive health.
Instead of:
“What is wrong with her?”
ask:
“What factors could be affecting us as a couple?”
Instead of:
“She needs fertility tests.”
say:
“We should both be assessed.”
This is medically more accurate and much fairer.
Pregnancy requires:
egg + sperm + timing + functioning reproductive systems.
So when pregnancy is not happening:
do not investigate only the woman.
Male factors contribute to many fertility difficulties, and a semen analysis is often one of the simplest and most useful early investigations.
Your partner should be evaluated early when appropriate—especially if he has:
testicular problems
sexual or ejaculation difficulties
previous cancer treatment
testosterone or anabolic steroid use
previous infertility
Fertility is not:
her problem.
It is:
our reproductive health.
