Embryogenesis - 23 Pairs of Chromosomes
The chromosomes are essentially the wrapped up DNA that contains all the genetic information to create any cell type in the body and actually to create an entirely new individual. There are 23 pairs of chromosomes, 22 of which are called autosomes. The goal of fertilization is to bring that egg cell into close enough proximity that it can be fertilized by a single sperm cell.
I discuss the mechanisms by which human eggs and sperm are generated, the ovulatory/menstrual cycle, the conception process and overall fertility in males and females. I also explain how, regardless of whether you seek to conceive children, optimizing egg and sperm health is directly related to vitality and longevity. I cover nutritional, behavioral, supplemental, and medicinal approaches to optimizing egg and sperm health, the ovulatory/menstrual cycle and fertility. In addition, I explain lifestyle choices that greatly assist or harm fertility—several of which are very surprising. I provide science-based protocols for those trying to conceive children. The tools and principles I discuss can also improve overall vitality and longevity for everyone, regardless of age.
