3-Month Preconception Plan for Couples in Switzerland

Alex and Lily had been together for six years. One evening in Zurich, they finally said it out loud:

“Let’s start trying.” But the next morning, both had the same question: how to prepare for pregnancy properly, not just stop contraception and hope.

They wanted a real preconception plan that Swiss couples could actually follow, clear, simple, and doctor-backed.

As Switzerland’s Swiss Vegan Fertility Leader, Plusbaby has helped hundreds of Swiss couples do exactly that.

This guide walks you through a complete 3-month preconception plan, what to do each month, and why it works.

Key takeaways

• Start folic acid (Quatrefolic®) at least 3 months before trying to conceive, not after.
• Both partners need to prepare. Sperm health matters just as much as egg quality.
• A preconception counseling appointment in Switzerland can catch problems before they slow you down.
• Nutrition, sleep, and cutting alcohol all have a real impact on fertility for men and women.
• Fertility supplements like +fertiwomen Inositol and +fertimen support this window. Always consult your doctor first.

Why 3 months? the science behind the window

The 3-month preconception plan is not a random number. Sperm take around 74 days to fully develop. Eggs take around 90 days to mature. And folic acid needs time to build up enough in your body’s tissue to protect a baby’s neural tube in the very first weeks of pregnancy, often before you even know you are pregnant.

Swiss health authorities and the WHO both recommend beginning preconception care in Switzerland at least 3 months before trying.

This window also gives time to identify any health issues, improve lifestyle habits, and let supplements take effect. Starting early is the single most effective thing a couple can do.

Your 3-month preconception plan at a glance

Month 1: laying the foundation

1. Book your preconception check-up

The first step in any good fertility preparation plan is a visit to your Swiss OB/GYN or Hausarzt.

Your doctor can check rubella immunity, thyroid levels, iron, and vitamin D. Women can also ask for AMH, a simple blood test that shows ovarian reserve. This is standard preconception counseling in Switzerland and is often covered by basic Krankenkasse (KVG).

2. Review medications and supplements

Some everyday medications, including certain antidepressants, blood pressure drugs, and even high-dose vitamin A, can affect fertility or early pregnancy. Month 1 is the time to go through everything you take with your doctor and make any needed changes. Do not stop any prescription medication without medical advice.

3. Start taking folic acid and cut alcohol

Folic acid is the most important item on any pre-pregnancy checklist in Switzerland. Look for Quatrefolic®, a methylated form that absorbs better.

Both partners should cut alcohol completely. Caffeine can stay at one to two cups a day. These are the easiest changes with the biggest payoff.

Before trying to conceive, it’s important to understand which essential fertility vitamins and minerals can support reproductive health and prepare your body for pregnancy.

Month 2: optimising your body together

1. Eat for fertility

Good fertility planning before pregnancy includes nutrition for both partners. A whole-food diet, vegetables, legumes, wholegrains, and healthy fats, covers most of what you need. Avoid ultra-processed foods and excess sugar. These are linked to poorer egg quality and lower sperm motility.
Alongside a structured preconception plan, there are several ways to increase your chances of getting pregnant naturally, including improving nutrition, sleep, and fertility-focused lifestyle habits.

2. Start fertility supplements

This is where pre-pregnancy vitamins and tests come together. For women, Myo-Inositol, the key ingredient in Plusbaby’s +fertiwomen Inositol, supports hormonal balance and ovulation.

Research continues to highlight the benefits of myo-inositol for fertility, particularly for women looking to support ovulation and hormonal balance.

For men, +fertimen combines 11 nutrients, including zinc, CoQ10, and L-Carnitine to support sperm health.

Both are formulated by Swiss doctors, 100% vegan, and are free from artificial additives.

Key supplements for both partners

Couples looking for a more structured fertility boost plan can combine targeted nutrition, fertility supplements, and healthy lifestyle habits to support conception.

3. Track your cycle and manage stress

Start tracking your cycle with an LH ovulation test or basal body temperature chart. This is one of the most practical parts of pregnancy prep for couples. At the same time, take stress seriously. High cortisol disrupts ovulation in women and reduces testosterone in men.

Simple habits, regular sleep, short walks, and reducing screen time before bed make a real difference to your hormonal environment.

Month 3: getting the timing right

1. Know your fertile window

By month 3, your couple’s preconception checklist is nearly complete. Now focus on timing. Your fertile window is the 5 days before ovulation and the day of ovulation itself. Having sex every 1–2 days during this window gives the best chance. Stress about timing can work against you; keep it relaxed.

Properly tracking your menstrual cycle can help you identify your fertile window more accurately and improve your chances of conceiving.

2. Reduce environmental toxins

Some everyday Swiss household products, plastic food containers, non-stick cookware, and certain cleaning sprays contain endocrine disruptors that can affect hormone levels. Swap to glass containers, choose natural cleaning products, and avoid heating food in plastic. small, easy changes.

3. Final pre-pregnancy checklist

Before you officially start trying to conceive, run through this:

• Blood tests done (thyroid, vitamin D, iron, rubella, AMH)
• Medications reviewed with your doctor
• Folic acid started (at least 4 weeks in, ideally 12)
• Both partners are taking supplements
• Alcohol stopped, caffeine reduced
• Cycle tracked, fertile window understood
• Home toxins reduced, plastics and chemicals reviewed

What the real Swiss couples say after the 3-month plan

⭐⭐⭐⭐⭐ Léa & Florian — Geneva

“We followed this plan exactly. I started +fertiwomen Inositol in Month 1, and Florian took +fertimen. By Month 3, we felt ready. We got pregnant on our second cycle. The structure helped us feel calm instead of anxious.”

⭐⭐⭐⭐⭐ Anna B. — Bern

“I have PCOS and was nervous about how long it would take. My doctor suggested inositol and folic acid three months ago. I also did all the recommended blood tests. We conceived naturally in month four of trying. Having a checklist made everything feel manageable.”

What Swiss couples often get wrong about preconception

Even well-informed couples make some common mistakes.

Here are the most frequent ones, and the truth behind them.

“It’s mainly the woman’s responsibility.”

Not true. Male fertility accounts for roughly half of all conception challenges. Men must be equally involved in the plan.

Understanding the most important male and female fertility factors can help couples identify potential obstacles and improve their chances of conception.

“Supplements work immediately.”

They need time. Most fertility nutrients require 6–12 weeks to reach effective levels. Starting in Month 1 matters.

“We’re young, so it will happen quickly.”

Age is one factor, but nutrition, stress, and lifestyle affect fertility at any age.

“Stress doesn’t affect fertility.”

It does. Chronic stress raises cortisol, which disrupts ovulation and testosterone production.

“We don’t need a doctor if we’re healthy.”

Even healthy couples benefit from a single preconception plan, a Switzerland check-up. Subclinical thyroid issues or vitamin D deficiency are common and easy to miss.

Faq: frequently asked questions

Question: How early should we start preparing for pregnancy?

Answer: Ideally, 3 months before. This covers the full sperm renewal cycle (~74 days) and allows folate and supplements to reach effective levels. A good 3-month preconception plan gives your body a real head start.

Question: Does the male partner really need to prepare, too?

Answer: Yes. Male fertility is responsible for roughly half of all conception challenges. Trying to conceive in Switzerland is a two-person effort. Both partners should follow the plan.

Question: Is preconception counseling covered by Swiss insurance?

Answer: Basic blood tests and gynaecology consultations related to preconception counseling in Switzerland are often covered by Krankenkasse (KVG). Confirm with your insurer and doctor.

Question: Can we take supplements while still on contraception?

Answer: Folic acid and most preconception nutrients are safe to start before stopping contraception. Always confirm with your doctor first.

Important: Before starting any supplement, including folic acid, inositol, or any Plusbaby product, please consult your doctor or gynaecologist first. Everybody is different, and a medical professional can advise what is right for your specific situation.
