When a couple is planning a pregnancy, there’s a lot of talk about the expectant mother: folic acid, vaccinations, medication, and gynecological care. The man’s role is often overlooked. Yet, the the health of the expectant father directly affects the couple’s fertility, the outcome of the pregnancy, and even the child’s long-term health. According to the Canadian Society for Fertility and Andrology, a male factor is involved in approximately 50 % cases of infertility [1]. The Male Preconception Screening yet it remains largely underutilized. This article explains why it’s worth it, what it covers, the habits that improve sperm quality, and when to seek medical advice in Quebec.

Why get a male preconception evaluation?
Visit Male Preconception Screening is a medical consultation that prepares the future father for conception. It is not just a fertility test: it is a overall opportunity to take stock of one's health, habits, and environment before a child joins the family. Ideally, this takes place 3 to 6 months before trying to conceive, because spermatogenesis—the production of sperm—takes about 70 to 90 days [2].
The main reasons to do so
- L’infertility has a male cause partial or complete in approximately 50 % of cases [1]
- Several medications, exposures, and habits affect sperm quality
- A healthy expectant father provides better support for his partner during pregnancy and the postpartum period
- This is the perfect opportunity to take a comprehensive look at one's health, get screened for STIs and get your vaccinations up to date
- A optimal health for the father Conception is associated with better outcomes for the child [3]
- Early identification of modifiable factors allows you to take action before they become an obstacle
What does a male preconception screening include?
The contents of a preconception evaluation is tailored to each man based on his age, medical history, and the couple's situation. It typically consists of several complementary components.
Personal History and Lifestyle Habits
- Consumption : tobacco, alcohol, cannabis, other substances
- Physical Activity, sleep, stress management
- Weight and food
- Professional exhibitions : heat, solvents, pesticides, heavy metals
- Saunas and Hot Baths frequent — their effect on spermatogenesis has been documented
- Personal Medical History : diseases, surgeries, testicular trauma, previous STIs
- Family history : genetic disorders, familial infertility, hereditary cancers
General Medical Evaluation
- Blood pressure, BMI, physical examination
- Metabolic Profile : fasting blood glucose, lipid profile
- STI Screening (HIV, hepatitis B and C, syphilis, gonorrhea, chlamydia)
- Vaccination : rubella (to protect a pregnant partner), pertussis (DTaP), annual flu, COVID-19, hepatitis B
- Mental health : Screening for Anxiety, Depression, and Problematic Substance Use
- Evaluation sexual function, as applicable (erectile dysfunction, decreased libido)
Which medications and substances should you watch out for?
Several medications and substances may affect male fertility or sperm quality, or pose a risk to a future pregnancy. A comprehensive review A review of all medications taken by the expectant father is therefore a key step in the preconception evaluation.
Categories to Watch Closely
- Anabolic Steroids — to stop before trying to conceive, including for former users (it may take several months for testicular function to return)
- Testosterone when administered exogenously — inhibits spermatogenesis
- Some Treatments for Baldness (finasteride) — discuss with your doctor
- Chemotherapy and Radiation Therapy previous — may affect fertility
- SSRI Antidepressants, certain antipsychotics — variable effects
- Opioids over the long term — lower testosterone levels
- Anti-inflammatory drugs in high doses over a long period
- Cannabis regular — documented effect on sperm quality [4]
- Cocaine, amphetamines — harmful effects
- Dietary Supplements — to be discussed; some contain active ingredients
Important : Never stop taking a prescribed medication without consulting a doctor. Talking with your doctor or a pharmacist will help you evaluate possible alternatives and determine the best schedule for adjusting your dosage.
When is a targeted fertility evaluation needed?
Visit male fertility evaluation It is usually recommended after a period of unsuccessful attempts, or earlier if known risk factors are present. The Canadian Society for Fertility and Andrology suggests the following thresholds [1].
Targeted Balance Sheet Criteria
- No pregnancy after 12 months regular unprotected sex
- No pregnancy after 6 months if the partner is 35 years old or older
- Background testicular surgery, varicocele, cryptorchidism (undescended testicle)
- Background chemotherapy, radiation therapy, or testicular trauma
- Known Genetic Abnormalities within the family
- Erectile or ejaculatory dysfunction persistent
Tests Typically Offered
- Semen Analysis — analysis of sperm concentration, motility, morphology, and volume
- Sperm Culture if infection is suspected
- Hormone Panel : total testosterone, FSH, LH, prolactin, and sometimes TSH
- Scrotal Ultrasound to check for a varicocele or another structural abnormality
- Genetic Testing in certain situations (karyotype, Y-chromosome microdeletions, CFTR mutations)
- Referral to a urology or fertility clinic based on the results
In Quebec, the Quebec Assisted Reproductive Technology Program covers certain tests and treatments based on specific criteria. A discussion with the primary care physician can help direct patients to the appropriate public or private resources.
What habits improve sperm quality?
Many lifestyle habits directly affect sperm quality. The good news is that, since spermatogenesis is a continuous process (with a cycle of about 70 to 90 days), improvements can be measured within a few months.
High-Impact Changes
- Quit Smoking — documented effect on sperm concentration and motility
- Limit Alcohol Consumption — limit consumption to moderate and occasional amounts
- Reaching a Healthy Weight — Obesity affects hormones and sperm quality
- Avoid prolonged exposure to excessive heat to the testicles (frequent saunas, hot baths, laptops on the lap)
- Moderate physical activity Regular — avoid extremes (a sedentary lifestyle or chronic intense exercise)
- A diet rich in antioxidants : vegetables, fruits, omega-3, nuts, legumes
- Reducing Occupational Exposure hazardous (heat, solvents, pesticides, heavy metals)
- Adequate sleep and of good quality (7 to 9 hours per night)
- Stress Management — yoga, meditation, physical activity, and psychological support as needed
Key Takeaways
- L’infertility has a male cause in about 50 % of cases
- Spermatogenesis takes 70 to 90 days — Start preparing 3 to 6 months in advance
- Tobacco, alcohol, cannabis, anabolic steroids have a documented negative impact
- Visit excessive heat Damage to the testicles reduces sperm quality
- A semen analysis is recommended after 12 months without pregnancy (6 months if the partner is 35 or older)
- Visit overall health The future father's health is just as important as his fertility profile
What environmental factors affect fertility?
In addition to personal habits, several environmental and occupational factors can affect male fertility. While they are sometimes more difficult to change, identifying them at least makes it possible to minimize exposure.
Exhibitions to Watch
| Exhibition Type | Common Sources | Potential effect |
|---|---|---|
| Excessive heat | Welding, foundries, long commutes, frequent sauna use | Reduced spermatogenesis |
| Organic solvents | Painting, industrial cleaning, mechanics | Sperm Toxicity |
| Pesticides | Agriculture, horticulture | Endocrine effects, sperm quality |
| Heavy Metals | Lead, mercury, cadmium (industry, batteries) | Reduced fertility |
| Discharges | Medical radiation therapy, certain industrial sectors | Damage to germ cells |
| Endocrine disruptors | Certain plastics (BPA), cosmetics, household products | Variable hormonal effects |
When occupational exposure is unavoidable, protective measures (equipment, ventilation, job rotation) can help mitigate the effects. Talking with an occupational physician or a family doctor can help you evaluate your options.
When to see a doctor?
Ideally, before trying to conceive
- 3 to 6 months before trying to conceive
- To make the comprehensive health assessment and get your vaccinations up to date
- For review medications and lifestyle habits
- For assess exposures professional and environmental
During the trial period
- No pregnancy after 12 months unprotected sex
- No pregnancy after 6 months if the partner is 35 years old or older
- Presence of’medical or family history at risk
- Current treatment that may affect fertility
- Sexual difficulties (erectile dysfunction, ejaculation)

Myths and Misconceptions
«Fertility is primarily a women's issue»
False. A male factor is involved in approximately 50 % of cases of couple infertility. A male evaluation is therefore just as important as a female evaluation and should be offered as soon as a couple begins planning to have a child.
«Men remain fertile throughout their lives»
Nuanced. Unlike women, men can remain fertile well into old age, but sperm quality gradually declines with age. The risk of certain genetic abnormalities and pregnancy complications also increases after the father turns 40 to 45 [5].
«Drinking one beer a day doesn't make a difference»
Nuanced. Occasional moderate consumption has a limited effect, but regular and heavy consumption affects testosterone levels, spermatogenesis, and sexual function. As part of preconception planning, it is recommended to significantly reduce consumption.
«Tight-fitting underwear reduces fertility»
A modest but real effect. Very tight underwear and prolonged exposure of the testicles to excessive heat may slightly reduce sperm quality. The documented effect remains modest compared to smoking or obesity, but it is a reasonable option to wear looser-fitting clothing during the preconception period.
«A normal semen analysis guarantees a quick pregnancy»
False. A normal semen analysis is reassuring but does not rule out all causes of infertility (female factors, combined factors, undetected functional abnormalities). Fertility is a complex phenomenon that involves both partners.
Frequently asked questions
At what age does male fertility begin to decline?
Male fertility gradually declines starting around age 40 to 45. Sperm concentration and motility decrease, and the risk of certain genetic abnormalities increases. This does not mean that pregnancy becomes impossible, but it may take longer to conceive, making preconception screening even more important.
How long after quitting smoking does sperm quality improve?
Since spermatogenesis takes about 70 to 90 days, the first improvements can be measured 2 to 3 months after quitting smoking. The benefits continue to accumulate in the months that follow. The longer a person has been smoke-free, the closer their test results become to those of a nonsmoker.
Does a normal semen analysis guarantee fertility?
No. A normal semen analysis is reassuring, but it primarily evaluates macroscopic parameters (count, motility, morphology). Certain functional or genetic abnormalities may go undetected. Conversely, a slightly abnormal semen analysis does not always prevent a spontaneous pregnancy.
Do hot baths and saunas really affect fertility?
Yes, when exposure is frequent and prolonged. The testicles function at a temperature slightly lower than body temperature. Excessive and regular heat temporarily reduces sperm production. It is recommended to limit saunas, prolonged hot baths, and prolonged use of a laptop directly on the lap during the preconception period.
Does cannabis affect male fertility?
Yes. Regular cannabis use is associated with a decrease in sperm concentration and motility, as well as impaired sperm morphology. Reducing or stopping use is generally recommended during the preconception period and the first few months of trying to conceive.
Is the preconception checkup covered by the RAMQ?
The medical consultation and several basic tests (blood tests, STI screening, semen analysis) are covered by the RAMQ. Some more specialized tests or those performed at a private clinic may incur costs. Group insurance plans may sometimes reimburse these costs. Contacting the clinic in advance can help clarify any potential costs.
