A long-term study out of the Netherlands found fetal brain development was most highly linked to the mother’s levels of thyroid stimulating hormone (TSH) early in pregnancy.1 During the first half of pregnancy, a mother’s thyroid levels are crucial to her baby’s brain development.2 Thyroid hormones are important to every cell in the body, regulating how they develop and metabolize proteins, … [Read more...]
Former Gardasil Researcher Leads Trial of Promising New Therapeutic HPV Vaccine
HPV vaccines currently on the market are meant as a prophylactic to prevent boys and girls as young as 9 from contracting the human papilloma virus and subsequent precancerous lesions that may arise from its more high-risk strains. While the long-term efficacy and concern over reports of serious adverse side effects have embroiled the makers of these vaccines in controversy and litigation, there … [Read more...]
The Moment of Fertilization Illuminated By a ‘Zinc Spark’
If the “Big Bang” is indeed the origins of our universe, it seems cosmically appropriate that the beginning of a singular life may be seen via its own little “spark.” A Zinc Spark that is. As it turns out, this little fireworks display is what causes the egg (now fused with the sperm) to start dividing again and develop into a baby, reigniting a process of cellular division that has been on … [Read more...]
Oral Birth Control Impairs Ability to Read Complex Emotions
What if your birth control could be partially to blame for relationship problems? A German study suggests it’s possible factor.

As I was writing the February article about sex hormones regulating autism-associated genes and the associated risk of high fetal testosterone levels, a thought occurred to me: if women with Polycystic Ovarian Syndrome (PCOS) have higher testosterone levels, do women with PCOS have a higher risk for having children with autism? Turns out that yes, they do, according to two corroborating … [Read more...]
Get to Know Your Sex Hormones
Let’s talk about sex ba-by! Or rather sex hormones (and you’re welcome for getting that old Salt-n-Pepa song stuck in your head!). There are three groups of sex hormones that are produced in the ovaries, testes, and adrenal gland: The Progestogens, the Androgens, and the Estrogens. Cholesterol gets a bad wrap, but actually it is very important in our bodies: from cholesterol Progestogens are … [Read more...]
Exercise Hormone Irisin May Fight Alzheimer’s Disease
Besides the standard health benefits of exercise, studies have shown exercise may also be able to help lower risk of Alzheimer’s disease and prevent its progression. However, it was poorly understood just how this effect was occurring at the molecular level. A new study published in Nature Medicine by researchers at Queen’s University in Ontario, Canada found the exercise hormone, irisin, is an … [Read more...]
