Trying to Conceive? Start With the Basics
You stop contraception. You download an ovulation app. You start watching every symptom. Then one month passes. Then another. And suddenly, something that was supposed to feel exciting starts feeling like a monthly examination.
“Did I ovulate?”
“Was the timing right?”
“Why hasn’t it happened yet?”
Trying to conceive is often presented as simple:
Have sex → get pregnant.
Biologically, it is much more complicated. Pregnancy requires coordinated function of ovulation, a healthy egg, functional fallopian tubes, a receptive uterus, healthy sperm and appropriate timing. Sometimes everything appears normal and pregnancy still takes time. 1
And importantly: Fertility is a couple’s issue—not a woman’s issue. 1
Quick Answer: How Long Does It Normally Take?
Infertility is generally defined as not achieving pregnancy after 12 months of regular, unprotected intercourse. 1
But you do not always need to wait 12 months before seeking help.
- Under 35: evaluation is generally recommended after 12 months.
- 35 or older: evaluation after 6 months.
- Over 40: earlier or immediate evaluation may be appropriate.
- Any age: seek help sooner if there are known fertility problems, very irregular or absent periods, endometriosis, previous pelvic surgery, recurrent pregnancy loss or suspected male-factor infertility. 2
The goal is not to panic early. It is to avoid unnecessary waiting when there is already a reason for evaluation.
When Is the Best Time to Have Sex?
You do not need to have sex every day of the month.
The fertile window is the period during which intercourse can result in pregnancy, centred around ovulation. Sperm can survive for several days in the female reproductive tract, while the egg remains viable for a much shorter period after ovulation.
Therefore, pregnancy is most likely when intercourse occurs during the days leading up to ovulation and around ovulation itself. 2
For couples trying naturally, intercourse every 1–2 days during the fertile window is generally sufficient. If tracking ovulation becomes stressful, regular intercourse throughout the cycle—roughly every 2–3 days—can also provide good coverage without requiring precise prediction.
How Do You Know You’re Ovulating?
Ovulation can be difficult to pinpoint exactly.
Useful clues include:
- Menstrual cycles: Regular cycles make predictable ovulation more likely, although they do not guarantee it.
- Cervical mucus: Around ovulation, cervical mucus may become clearer, wetter and more slippery.
- Ovulation predictor kits: These detect the luteinising hormone surge that usually occurs shortly before ovulation.
- Ultrasound: A clinician can monitor follicular development when medically indicated.
- Progesterone testing: A properly timed progesterone test can provide evidence that ovulation occurred. 2
If periods are consistently very irregular or absent, do not rely only on an app. The underlying cause of irregular ovulation needs to be evaluated. PCOS (PMOS), thyroid disorders, significant weight changes, excessive exercise, high prolactin and other conditions can affect ovulation. 1 2
Your Age Still Matters
Healthy lifestyle, regular periods and good ovarian reserve are valuable—but they cannot completely cancel reproductive ageing.
As women age, both egg quantity and egg quality change. Fertility declines with increasing age, with the decline becoming more noticeable through the mid-to-late 30s. Increasing age is also associated with a higher risk of chromosomal abnormalities in eggs and miscarriage. 2
This does not mean: 35 = infertile.
It means that age is one of the strongest factors influencing the probability of conception. 2
That is why women 35 and older are generally advised not to wait as long before seeking an evaluation if pregnancy has not occurred.
What About AMH?
AMH is frequently marketed as a fertility score.
It isn’t.
AMH mainly provides information about ovarian reserve—the approximate quantity of eggs remaining.
It does not directly measure egg quality and cannot tell a woman exactly how long she has before menopause or whether she will become pregnant naturally. Ovarian reserve testing should not be used as a general screening test in women who do not meet criteria for infertility; it is an adjunct to fertility evaluation when clinically indicated. 2
A woman with low AMH may conceive. A woman with reassuring AMH may still experience infertility because of age, ovulation problems, blocked tubes, endometriosis or sperm factors. 1 2
So: Don’t let one number define your fertility. Ovarian reserve testing is most useful when interpreted alongside age, menstrual history and the clinical situation.
And Yes—Male Fertility Matters
This deserves its own section because too often the woman becomes the first—and sometimes only—person investigated. That isn’t evidence-based fertility care.
The WHO estimates that approximately one in six people of reproductive age worldwide experience infertility during their lifetime. Infertility may result from male factors, female factors, combined factors or unexplained causes. 1 6
The AUA/ASRM guideline recommends that both partners undergo concurrent assessment, with the male partner’s reproductive history and semen analysis forming an important part of the initial assessment. 4
The Urological Society of India similarly recommends simultaneous investigation of both partners. 5
What Can Cause Male-Factor Infertility?
Male fertility can be affected by:
- Low sperm count
- Poor sperm movement
- Abnormal sperm morphology
- Complete absence of sperm
- Varicocele
- Hormonal disorders
- Previous infections or reproductive-tract obstruction
- Testicular conditions
- Certain medications
- Anabolic steroid use
- Smoking and excessive alcohol
- Obesity and some metabolic conditions
- Previous chemotherapy or radiation
- Some genetic conditions
And sometimes, no clear cause is found. 1 4
The first test is usually simple: Semen analysis - It assesses characteristics such as sperm concentration, movement and morphology. 4
One abnormal result does not automatically mean infertility. Semen parameters can vary between samples, which is why repeat testing may be recommended when the first result is abnormal. 4
And importantly, male infertility can sometimes reveal another health problem requiring treatment.
Female Fertility: What Else Can Affect Conception?
Even when ovulation is occurring, pregnancy may not happen if other parts of the reproductive system are affected.
- Fallopian tubes: Blocked or damaged tubes can prevent sperm and egg from meeting. Tubal problems can occur after certain infections, pelvic surgery or other conditions. 1
- Endometriosis: Endometriosis can affect fertility through inflammation, adhesions and ovarian or tubal involvement. 1
- Uterine conditions: Fibroids, polyps, adenomyosis and some structural abnormalities can affect reproductive outcomes depending on their location and severity. 1 2
- PCOS (PMOS): PCOS (PMOS) is a common cause of irregular or absent ovulation. But having PCOS (PMOS) does not mean pregnancy is impossible. Many women conceive naturally or with treatment. 1
- Thyroid disorders: Thyroid dysfunction can affect menstrual cycles and ovulation. If you have known thyroid disease, appropriate assessment and treatment before and during pregnancy are important. 2 3
When Should You Get Tested?
A fertility evaluation should not mean immediately ordering every available test. A good evaluation begins with history and targeted testing. Current guidance emphasises systematic, clinically directed evaluation rather than automatically ordering every possible investigation. 2 3
For the woman, this may include:
- Menstrual and ovulation history
- Medical and reproductive history
- Appropriate hormonal testing
- Pelvic ultrasound
- Assessment of ovarian reserve when indicated
- Evaluation of the uterus and fallopian tubes when appropriate
For the man:
- Reproductive and medical history
- Sexual and medication history
- Physical examination when indicated
- Semen analysis 2 4
The exact tests depend on the couple. More testing isn’t automatically better testing. The aim is to identify the likely cause while avoiding unnecessary expense, procedures and anxiety. 2
Lifestyle: What Actually Helps?
There is no fertility detox. There is no magic fertility food. And infertility is not proof that you “didn’t live healthy enough.” But certain habits support reproductive health.
- Eat a balanced diet: Prioritise vegetables, fruits, whole grains, pulses, adequate protein and healthy fats.
- Maintain a healthy weight: Both underweight and obesity can affect reproductive function. 1
- Exercise regularly: Moderate physical activity supports overall health. Extremely intense exercise combined with inadequate energy intake can interfere with ovulation.
- Avoid smoking: Smoking can negatively affect fertility in both women and men. 1
- Limit excessive alcohol: Excessive alcohol consumption can affect reproductive health. 1
- Review medications: Some medications and anabolic steroids can affect fertility. Never stop prescribed medication without medical advice. 1 4
- Start folic acid before pregnancy: Women planning pregnancy should discuss appropriate folic acid supplementation with their healthcare professional.
What About Stress?
This deserves its own myth-busting moment. Stress does not explain every case of infertility. Telling someone: “Just relax and you’ll get pregnant.” is neither compassionate nor medically sound. Infertility itself can cause significant stress, anxiety, relationship strain and financial pressure. 1
At the same time, sleep, mental wellbeing, exercise and emotional support are important while trying to conceive. The goal isn’t to become perfectly stress-free. It is to make the process psychologically sustainable.
When Pregnancy Doesn’t Happen
If you have been trying for months without success, it is easy to start blaming yourself.
Maybe you think:
- “I should have tried earlier.”
- “I must have done something wrong.”
- “Maybe it’s because I stressed too much.”
Stop there. Infertility can have female causes, male causes, combined causes or no clearly identifiable cause. 1
It is not a moral failure. It is not a punishment for waiting. And it is not automatically the woman’s responsibility to fix. A proper fertility evaluation is about finding information—not finding someone to blame.
What Treatment Might Look Like
Treatment depends entirely on the cause.
It may involve:
- Optimising ovulation
- Treating thyroid or other hormonal disorders
- Managing PCOS (PMOS)
- Treating endometriosis or certain uterine conditions
- Surgery for selected tubal or structural problems
- Treating specific male-factor conditions
- Ovulation induction
- Intrauterine insemination (IUI)
- In-vitro fertilisation (IVF)
- Intracytoplasmic sperm injection (ICSI)
- Other assisted reproductive options 3 4
Not every couple needs IVF. And IVF isn’t a failure of natural conception. It is one of several medical tools available when appropriate. The right treatment depends on the cause, age, duration of infertility and individual circumstances. 3
When to See a Doctor
You should consider a fertility evaluation:
- After 12 months of regular unprotected intercourse if the woman is under 35.
- After 6 months if the woman is 35 or older.
- Earlier or immediately if the woman is over 40.
- At any age if there are very irregular or absent periods, known or suspected endometriosis, known tubal or uterine disease, previous pelvic surgery, recurrent pregnancy loss or suspected male-factor infertility. 2
And when evaluation is needed, both partners should generally be assessed together. 4
Key Takeaways
- Pregnancy requires coordinated function of ovulation, egg, sperm, tubes, uterus and hormones. 1
- The fertile window surrounds ovulation; intercourse every 1–2 days during this window is generally sufficient. 2
- Fertility declines with age, particularly through the mid-to-late 30s. 2
- AMH measures ovarian reserve, not overall fertility. 2
- PCOS (PMOS), endometriosis, thyroid disorders and tubal or uterine conditions can affect conception. 1
- Male-factor infertility is an important part of the fertility picture. 1
- Both partners should generally be evaluated together when infertility is suspected. 4
- A semen analysis is an important first-line test for the male partner. 4
- Healthy lifestyle habits support fertility but cannot eliminate biological factors such as age. 1
- Infertility may be female, male, combined or unexplained. 1
- Seeking help is not failure—it is good healthcare.
