corpus luteum


Progesterone levels in the blood come from the corpus luteum and are helpful after ovulation and to find out if you ovulated or not. Low progesterone levels are not normal.When you ovulate there is an area in the ovary called "corpus luteum" which is responsible for the production of progesterone.

Low progestone levels below 10 ng/ml usually mean that ovulation has likely not happened or you tested too early, less than a week after ovulation.


A new study published in the Journal of Assisted Reproduction and Genetics links the early placenta to pregnenolone production. Research was completed by authors from the New York University School of Medicine.


A pregnant miscarriage, also referred to as a spontaneous abortion,
occurs in a small number of pregnancies. Typically, pregnant miscarriage
happens before the end of the first trimester, but it can happen at any
time in the pregnancy. Among reasons for a loss of pregnancy, pregnant
miscarriage is number one. The American College of Obstetricians and

female body does not always live up to this expectation. Urine
pregnancy tests tell the woman when to test for pregnancy and even offer
a 99% accuracy rate, but that means nothing to the woman who is not
releasing enough HCG two to three days before her menstrual cycle to


Stages in pregnancy are often divided up into weeks or trimesters.
Within these common stages in pregnancy are six major times of change.

The first trimester of pregnancy is often considered the second most exciting time during pregnancy. Birth is, of course, the most exciting time. During the first trimester of pregnancy, women find out they are pregnant, attend the first prenatal appointment and notice a long list of changes in their body. Understanding what happens in the body during the first trimester of pregnancy is important as some changes may not feel the way a pregnant woman expected.

 


Pregnancy tests are a diagnostic tool used in the home or a clinical
setting to verify pregnancy. In years past, women would have to wait
until after they missed their menstrual cycle to make an appointment
with a gynecologist to diagnose pregnancy. Home pregnancy tests changed
the face of fertility by allowing couples to use a pregnancy test at
home without the aid of a doctor. While there are faulty pregnancy tests


The fertility cycle is broken into two parts. The first half of the
fertility cycle is when the follicle stimulating hormone stimulates
maturation of an egg. As the egg is maturing, estrogen levels rise
causing the luteinizing hormone to increase. The luteinizing hormone
forces the egg out of the follicle where maturation occurs.
