After ten months of trying to conceive, her gynaecologist ordered a blood test. The result showed a high TSH. It was her first clear sign that thyroid and fertility are closely linked.<\/p>\n<p>Sofia&#8217;s situation is common in Switzerland. The thyroid is a small gland in the neck. It controls energy use in almost every cell, including the ovaries. When the thyroid works too slowly, ovulation can become less regular.<\/p>\n<p>As the Swiss Vegan Fertility Leader, Plusbaby creates vegan fertility vitamins in Switzerland and wants women like Sofia

It is also called an underactive thyroid.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"The_link_between_thyroid_hormones_prolactin_and_the_cycle\"><\/span>The link between thyroid hormones, prolactin and the cycle<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>When thyroid hormone is low, the brain releases more of a signal called TRH. TRH can also raise prolactin. A high prolactin level can delay or block ovulation. This is one way hypothyroidism fertility problems begin.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Subclinical_hypothyroidism_and_time_to_conception\"><\/span>Subclinical hypothyroidism and time to conception<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Some women have a high TSH but a normal FT4. Doctors call this subclinical hypothyroidism. Studies on its effect on hypothyroidism fertility outcomes show mixed results.<\/p>\n<p>Many doctors still treat it before IVF. For underactive thyroid conception planning, this decision belongs to your doctor.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Signs_worth_mentioning_to_your_doctor\"><\/span>Signs worth mentioning to your doctor<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Sofia had noticed some of these signs:<\/p>\n<ul>\n<li>Irregular or long cycles<\/li>\n<li>Heavy periods<\/li>\n<li>Tiredness that does not improve with rest<\/li>\n<li>Dry skin, hair loss or constipation<\/li>\n<\/ul>\n<p>Only a blood test can show if the thyroid is involved.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"TSH_FT4_and_Antibodies_Why_Your_Target_Should_Come_From_Your_Doctor\"><\/span>TSH, FT4 and Antibodies: Why Your Target Should Come From Your Doctor<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Sofia wanted a simple number.

Our guide on <a href=\"https:\/\/plusbaby.ch\/en\/blog\/when-to-start-fertility-supplements-before-trying-to-conceive\/\">when to start fertility supplements before trying to conceive<\/a> helps you plan this preparation time.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Normal_range_vs_preconception_target\"><\/span>Normal range vs preconception target<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Before conception or IVF, some guidelines prefer a lower TSH. Guidelines differ on the exact cut point. Many women search for thyroid TSH fertility Switzerland advice and find different numbers. This is why a blog cannot give you a safe personal target.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Who_manages_it_in_Switzerland\"><\/span>Who manages it in Switzerland?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In Switzerland, your GP or gynaecologist usually orders the first test. An endocrinologist may join if needed. Good thyroid TSH fertility Switzerland care means all these doctors share the same information.<\/p>\n<div class=\"gradient-cta\" style=\"padding: 10px; border: 1px solid #000;\">\n<p><strong>Nutritional Support Alongside Your Thyroid Care<\/strong><\/p>\n<p>Your doctor treats your thyroid. +fertiwomen Inositol, one of the women&#8217;s fertility vitamins in Switzerland formulated by Swiss doctors, supports ovulation and hormonal balance.<\/p>\n<p><a href=\"https:\/\/plusbaby.ch\/en\/product\/plusfertiwomen\/\">See how +fertiwomen Inositol works \u2192<\/a><\/p>\n<\/div>\n<h2><span class=\"ez-toc-section\" id=\"Hashimoto_Is_Not_the_Same_as_One_Low_Result\"><\/span>Hashimoto Is Not the Same as One Low Result<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"What_Hashimotos_thyroiditis_actually_means\"><\/span>What Hashimoto&#8217;s thyroiditis actually means<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Hashimoto&#8217;s thyroiditis is an autoimmune condition. The immune system slowly damages the thyroid. It is the most common cause of hypothyroidism in Switzerland.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Positive_antibodies_with_normal_TSH\"><\/span>Positive antibodies with normal TSH<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Some women have positive TPO antibodies but a normal TSH. A large trial called TABLET gave levothyroxine to these women before conception. It did not increase the live birth rate.<\/p>\n<p>For this reason, doctors usually monitor TSH instead of starting treatment at once. Hashimoto fertility planning therefore focuses on regular tests.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_one_test_is_rarely_enough\"><\/span>Why one test is rarely enough<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>TSH can change with illness, stress, and some medicines. Your doctor may repeat the test before making a diagnosis.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Can_You_Conceive_Once_Your_Thyroid_Is_Treated\"><\/span>Can You Conceive Once Your Thyroid Is Treated?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Sofia&#8217;s next question was simple: will treatment help?<\/p>\n<h3><span class=\"ez-toc-section\" id=\"How_treatment_helps_restore_regular_ovulation\"><\/span>How treatment helps restore regular ovulation<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Levothyroxine replaces the missing thyroid hormone. When levels reach the target range, prolactin often falls and cycles can become more regular. Treatment is the foundation of hypothyroidism fertility care. Many women with treated hypothyroidism conceive naturally.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Why_doctors_want_levels_stable_before_you_try\"><\/span>Why doctors want levels stable before you try<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Doctors adjust levothyroxine doses slowly. A blood test is usually repeated 6 to 8 weeks after each change. Stable levels before conception give early pregnancy the best start.

Some studies suggest it may lower TPO antibodies. Too much selenium can be harmful. High doses should only be taken with medical advice.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Iron_ferritin_and_thyroid_function\"><\/span>Iron, ferritin and thyroid function<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The thyroid needs iron to make its hormones. Low iron stores, shown by a low ferritin level, are common in women who are trying to conceive. Your doctor can test ferritin and decide if you need extra iron.<\/p>\n<p>Our <a href=\"https:\/\/plusbaby.ch\/en\/blog\/swiss-prenatal-nutrition-folate-iron-guide\/\">Swiss women&#8217;s guide to prenatal nutrition, folate and iron support<\/a> explains these nutrients in more detail.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Iodine_in_Switzerland_iodised_salt_and_diet\"><\/span>Iodine in Switzerland: iodised salt and diet<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Switzerland has added iodine to table salt for about one hundred years.

Hypothyroidism can disturb ovulation, so conception often takes longer. With treatment and stable thyroid levels, many women conceive naturally.<\/p>\n<p><strong>Question: What TSH level is good for conceiving?<\/strong><br \/>\n<strong>Answer<\/strong>: There is no single number for every woman. Guidelines differ, and targets are often stricter before IVF. Your doctor sets your target based on your history.<\/p>\n<p><strong>Question: Can I get pregnant naturally with Hashimoto\u2019s thyroiditis?<\/strong><br \/>\n<strong>Answer<\/strong>: Yes, many women do. Regular TSH tests and treatment when needed are the key steps in Hashimoto fertility care. Your doctor may also check TSH again in early pregnancy.<\/p>\n<p><strong>Question: Can a man\u2019s thyroid affect fertility too?<\/strong><br \/>\n<strong>Answer<\/strong>: Yes. Thyroid problems in men can affect sperm quality. A partner with symptoms should also speak with his doctor.

Take levothyroxine on an empty stomach and the supplement about four hours later.
