The placenta synthesizes progesterone primarily from pregnenolone, which is derived from cholesterol. Maternal cholesterol is converted to pregnenolone in the placenta, and then it undergoes several enzymatic transformations to produce progesterone. This hormone is crucial for maintaining pregnancy by supporting the uterine lining and preventing contractions. Additionally, some progesterone is also produced from maternal and fetal adrenal precursors.
What else can I help you with?
Once you are off progesterone shots at 12 weeks pregnant does the placenta always produce progesterone or is it possible that the placenta won't produce progesterone?
From what both my doctors have told me the placenta is producing its own progesterone by week 12. I just stopped taking crinone and Im nervous Im 12 weeks 4 days pregnant.

Which hormone keeps endometrium in the secretory phase to support a pregnancy?
Corpus luteum from ovary produce the hormone, progesterone. After the implantation of the pregnancy the endometrium terns into decidua. Then onwards the placenta produces the hormone, progesterone to term.
The human placenta secretes what?
estrogens, progesterones, and human chorionic gonadotropin (HCG)
What are all the organs that prduce estrogen and progesterone?
Most commonly ovaries of women.And placenta is a temporary gland.
Which glands secrete estrogen and progesterone besides the ovaries?
Placenta produces those hormones.But it is a temporary gland.
Which hormone released by the placenta during the 2nd and 3rd trimesters helps to sustain the pregnancy?
That hormone is called as progesterone. Placenta starts to produce this hormone from the first trimester only.
What structure maintains the levels of estrogen and progesterone in the frist few weeks of pregnancy?
It is the placenta. It is a temporary endocrine gland
What is the hormone responsible for pregnancy?
HcG is tested for pregnancy.HcG stands for Human Chorionic Gonadotrophin.
What steroid does the placenta produce during pregnancy?
During pregnancy, the placenta produces several hormones, with progesterone being one of the key steroids. Progesterone helps maintain the uterine lining, supports fetal development, and prevents contractions. Additionally, the placenta also produces estrogens, which play a vital role in regulating various physiological changes during pregnancy. Together, these steroids are crucial for a successful pregnancy.
How the level of a hormone which prevents menstruation remains high during pregnancy even after the corpus luteum has broken down?
Progesterone is the hormone that prevents menstruation and maintain pregnancy. It is initially produced by the corpus luteum. After the corpus luteum has broken down, the placenta takes over the production of progesterone from the 8th week of pregnancy until birth. Therefore, it is the placenta which keeps the level of the hormone (progesterone) high throughout pregnancy.
Is the placenta considered a gland?
Yes, the placenta is considered an endocrine gland because it secretes hormones such as estrogen, progesterone, and human chorionic gonadotropin (hCG) that play important roles during pregnancy.
How long do you take progesterone during pregnancy?
It depends on your levels. Typically, progesterone is taken from the very beginning of pregnancy (sometimes before) until about 12 weeks, when the placenta takes over the functions of the ovaries. Frequent blood draws will indicate when you can begin weaning off the progesterone.
