Dr. Elise Schroeder talks about the difference between progesterone and progestins, terms which are often used interchangeably by mistake. www.zrtlab.com
Thank you for the information. It is basically clear in your explanation. At the end you say Progesterones are better than Progesterones but you meant to say Progesterones are better than Progestins. Tiny detail
@1:48 - what is the stronger affect on the endometrium you mention here? I'm researching the claim that while natural progesterone produced by the body is vital to maintain a pregnancy, synthetic progestin actually works against implantation. Pro-life based science seems to suggest this, while others maintain that if break-thru ovulation and fertilization occurs, the fetus will implant, even after Plan B or having a Mirena in place. Any thoughts?
My research has concluded that if you take emergency contraception 3-5 days before ovulation aka before peak Luteinizing Hormone then the progestins cause the endometrium to underdevelop causing the zygote to not implant. But if LH has reached its peak the endometrium has reached a thickness positive for implantaion to occur if the egg has been fertilized and has made its way to the uterus.
