Keywords

Q&A

• What is AMH and why is it important for women to know their levels?

  AMH (Anti-Müllerian Hormone) is a hormone that indicates ovarian reserve, or the number of eggs a woman has. Knowing your AMH level is important because it can provide insights into your reproductive timeline, potential fertility challenges, and the likelihood of success with fertility treatments like IVF or egg freezing.

• How does fertility relate to overall health in women?

  Fertility is a key indicator of a woman's overall health. Good hormonal balance, cellular function, and metabolic health are all necessary for fertility. Conditions that impair fertility, like infertility itself, are often linked to increased risks of chronic diseases such as metabolic syndrome, cancer, and cardiovascular issues.

• Is it true that egg freezing or IVF can cause a woman to go into menopause earlier?

  No, this is a common myth. The process of egg freezing or IVF stimulates eggs that are already developing and outside the ovarian "vault." It does not deplete your ovarian reserve or accelerate the onset of menopause. You are simply maximizing the use of eggs that would naturally be lost that month.

• What is the difference between egg freezing and creating embryos?

  Egg freezing involves retrieving and freezing unfertilized eggs. Creating embryos requires fertilizing those eggs with sperm, allowing them to develop to the implantation stage. This distinction is important for ethical and personal decision-making regarding fertility preservation.

• Why is proactive fertility testing, like AMH, recommended even if a woman isn't currently trying to conceive?

  Proactive testing like AMH allows women to understand their reproductive health and timeline. This knowledge empowers them to make informed decisions about family planning, career, and potential fertility treatments, rather than being dictated by time or unexpected health changes.

• Can taking hormonal birth control long-term negatively impact fertility?

  No, large-scale studies indicate that hormonal birth control does not cause long-term infertility. While it prevents ovulation during use, fertility typically resumes shortly after discontinuing the medication.

• What is "Trimester Zero" and why is it important for fertility?

  Trimester Zero refers to the critical 90 days before conception for sperm development and 60 days for egg maturation. Lifestyle choices during this period significantly impact gamete quality, influencing conception success and overall reproductive health.

• How do NSAIDs affect the ability to get pregnant?

  Non-steroidal anti-inflammatory drugs (NSAIDs) like ibuprofen can prevent the rupture of ovarian follicles, which is essential for ovulation. Therefore, it is generally recommended to avoid NSAIDs when actively trying to conceive.

• What are the risks associated with advanced paternal age?

  Advanced paternal age (over 50) is linked to an increased risk of new genetic mutations in sperm, which can lead to a higher chance of certain developmental disorders, including autism and schizophrenia, in offspring.

• Can everyday products with endocrine disruptors affect fertility?

  Yes, endocrine-disrupting chemicals (EDCs) found in many household products and cosmetics can interfere with hormone function and negatively impact fertility. Minimizing exposure to these chemicals is advisable.

• What is the role of sleep in fertility?

  Adequate sleep is crucial for fertility as it helps reduce inflammation, manage cellular stress, and regulate reproductive hormones. Poor sleep can negatively impact testosterone levels, sperm count, egg yield, and overall fertility.

• Are there any supplements that can improve egg or sperm quality?

  Yes, supplements like CoQ10 and L-carnitine have shown promise. CoQ10 is recommended pre-conception for egg quality, while L-carnitine is beneficial for sperm health. Vitamin D and omega-3 fatty acids are also generally recommended.

• Does cannabis use affect fertility?

  Yes, cannabis use is significantly detrimental to fertility for both men and women. It can reduce sperm count and quality, increase miscarriage rates, and negatively impact egg yield and fertilization rates.
