5 ways in which Thyroid problems may affect fertility

An optimal thyroid function is necessary for a healthy reproductive system. It is essential for your ability to conceive successfully, have a healthy pregnancy and to deliver a baby without complications.

Here are 5 ways in which thyroid problems may affect your fertility and your ability to have a baby:

  • Lack of Ovulation

A poorly treated thyroid condition, or an undiagnosed one, can leave you at a greater risk of experiencing an “anovulatory cycle”, a cycle when you don’t release an egg. When the egg does not release, there is no chance of conception and pregnancy. Even if you have a menstrual cycle, you still can’t become pregnant if you have anovulatory cycles. Proper treatment may reduce the risk of infertility. However, apart from thyroid problems, there may be other potential reasons for anovulatory cycles which include perimenopausal changes, adrenal dysfunction, anorexia, ovarian issues and PCOS etc. Discuss these with your doctor if you’re trying to get pregnant.

  • Luteal Phase Defects

Luteal phase is the second half of your menstrual cycle. It is during the luteal phase that the egg is released and begins its journey through the fallopian tube, where it may be fertilized by a sperm to begin pregnancy. It takes 13 to 15 days for the egg to implant on the uterine lining. If the luteal phase is too short, it does not give enough time for successful implantation and the fertilized egg may be expelled along with menstrual blood. Proper diagnosis of thyroid and treatment may help resolve luteal phase defects.

  • Pregnenolone Conversion Issues

One of the most important functions of thyroid is to convert cholesterol into the hormone pregnenolone. It is a precursor hormone which is converted into progesterone, estrogen, testosterone, and DHEA. Deficient thyroid hormone may lead to deficiencies in other key hormones and can disrupt menstrual cycle. This may impair fertility and lead to problems in conceiving. Proper treatment and hormone replacement may help.

  • Sex Hormone Binding Globulin (SHBG) Imbalance

Thyroid problems may reduce the levels of sex hormone binding globulin (SHBG), which is a protein that attaches to estrogen. Low SHBG can lead to high estrogen which can interfere with the growth and development of your follicles, FSH and LH surges associated with ovulation. SHBG can be measured by blood test, to evaluate whether a deficiency or excess is affecting your fertility.

  • Early Perimenopause / Menopause

Thyroid conditions put you at an increased risk of having an early onset of menopause. Perimenopause refers to the timeframe when hormonal levels shift and decline and may last for as long as 10 years prior to menopause. Untreated or undiagnosed thyroid conditions may lead to perimenopause and menopause beginning early, thereby shortening childbearing years and causing reduced fertility at an earlier age. A full fertility evaluation needs to be performed by your doctor to know more and suggest the course of action.

When you’re trying to conceive, make sure that your doctor knows about your thyroid condition. This will help them chart out steps to ensure optimal thyroid health and increase your chances of conceiving. To know more, visit our team of gynecologists at KIMS Cuddles.

Myths About Fertility Treatments

Fertility treatments are vulnerable to misinformation. They exist at the intersection of medicine, emotion and personal hope of being a parent. Myths about IVF and infertility treatment circulate freely in conversations and on social media. Although people mean well, inaccurate advice without any clinical basis can lead a person to accept random myths. These myths can delay decisions for couples struggling to conceive but are unsure about IVF. It can lead to unnecessary anxiety and expectations that are not true. Therefore, understanding IVF myths facts can help people go through this journey smoothly.Myth: IVF Guarantees PregnancyThis is one of the most damaging misconceptions because it sets couples up for profound disappointment when a cycle does not result in a baby. IVF is an infertility treatment, but it does not mean pregnancy is always possible. IVF success reality is different because there are various factors involved in it. For women under 35, live birth rates are only 40-50% per cycle. These rates decline with age. Many couples may need multiple cycles, and even with repeated attempts, not every couple achieves a pregnancy. Starting treatment with accurate expectations can protect mental health and also help couples make informed decisions at each stage. Myth: IVF is the only Fertility Treatment OptionMany people believe IVF can solve

IVF Success Factors Explained

One of the first questions almost every couple asks when considering IVF is a simple one: what are our chances? The honest answer is that there is no single figure that applies to everyone. IVF success is shaped by a combination of biological, clinical, and lifestyle variables that interact differently for each person. Understanding what those variables are, and which of them can be influenced, helps couples approach treatment with realistic expectations and a clearer sense of what they can do to optimise their outcomes.Age: the most significant factorThe number one factor in IVF success is the age of the mother or egg donor. The younger the egg, the better its quality and the higher the probability of normal genetics.Women under 35 usually have success rates over 30% per cycle. Women over 40 may see rates below 10%. After three cycles, the cumulative success rate can reach 50 to 60% or more, depending on the population and other factors.The reason age matters so profoundly is egg quality. As women grow older, more eggs are affected by chromosomal abnormalities that lessen the possibility of fertilisation, hinder embryo development, raise the risk of miscarriage and decrease the odds of a successful pregnancy. This is not something IVF can fully overcome. It is why women using eggs

When Should Couples Seek Fertility Help?

Most couples who decide they want to start a family assume conception will happen relatively quickly. When it does not, the months of trying can bring a mix of confusion, frustration, and worry, along with a question that many are unsure how to answer: at what point does this become something to investigate medically? The answer depends on age, medical history, and a few specific circumstances that should prompt earlier rather than later action.Waiting too long to seek help is one of the most consistently documented patterns in fertility care. Most couples attempt to conceive for 22.3 months before presenting for fertility evaluation, almost a year beyond the recommended threshold. This delay can impair quality of life, impact treatment outcomes, and increase overall healthcare costs.The standard timelines for seeking helpFor a healthy couple in which the woman is under 35, infertility is typically defined as no pregnancy after 12 months of regular, unprotected intercourse. If the woman is 35 or older, the recommendation is to seek help after six months of trying without conceiving, since female fertility declines with age.If a woman is over 40, or a condition known to cause infertility is present, evaluation should not be delayed at all.These timelines reflect the biology of fertility decline. A 32-year-old and a 39-year-old are not in
