Often, the hormone called progesterone functions as an unstoppable force of nature in the fertility cycle. It’s necessary to know what the influence of progesterone is on conception, as it has multiple implications in the body, but quite little is popularly known. 

At Babynova we are at the forefront of reproductive methods, and we keep our patients informed of everything that is happening in the field of health and the functioning of their bodies. 

We do this in order to be their best guide in the assisted reproduction method of their choice.

Progesterone is a hormone that not only dictates the rhythm of the menstrual cycle but also influences pregnancy. But its role doesn’t end there, as it’s produced in the adrenal glands and the liver, it’s a critical hormone in the reproductive process.

Progesterone and pregnancy

Progesterone not only promotes gestation, it makes it possible. 

It’s the perfect balance of this hormone that allows life to flourish. When progesterone levels are adequate, the endometrium becomes a welcoming nest for the embryo. Whether produced naturally or administered to aid nature, this hormone is the key that unlocks the door to the possibility of pregnancy.

Understanding the second phase of the menstrual cycle is vital when longing for the arrival of a new being. In this delicate period, which is completed in 10/14 days and in which the follicle grows and prepares for ovulation, progesterone plays a vital role, and its levels must remain adequate.

This is because during the first phase of the female cycle, it shows higher levels, and during the second phase it shows lower levels. Therefore, it’s essential to maintain a precise balance, since any alteration could hinder embryo implantation and, with it, the dream of conceiving.

Normal levels during pregnancy

Pregnancy is a dynamic endocrine process, with progesterone playing an essential role. During the first trimester, progesterone levels vary from 10 to 44 ng/ml, and it’s critical for early embryonic development. 

In the second trimester, the level increases between 19.5 and 82.5 ng/ml, and again, it’s crucial for fetal growth and uterine protection. 

In the third trimester, the level rises further, from 65 to 290 ng/ml, preparing the uterus for delivery and sustaining and nourishing the pregnancy. 

These levels are more than just numbers, they are vital for a healthy and balanced pregnancy, ensuring the well-being of the fetus. 

As we can see, progesterone is key at every single stage.

Progesterone concentration during In Vitro Fertilization (IVF)

Sometimes, when natural pregnancy is not possible, assisted reproductive methods such as In Vitro Fertilization (IVF) are used. This process involves the union of eggs and sperm outside the body, in a controlled laboratory environment. After this union, the embryo is transferred to the uterus, and then exogenous progesterone is administered to promote implantation, as it prepares the endometrium and increases the chances of pregnancy.

Progesterone is used in vaginal soft capsules of 200 mg every 8 hours or 400 mg every 12 hours, or by subcutaneous injections of 25 mg daily. If the pregnancy test is negative, progesterone is discontinued; if it’s positive, it continues to be administrated until 8-12 weeks gestation. This hormone is vital for the success of IVF, ensuring the right environment for the development of the pregnancy. 

In Babynova Clinic we prioritize that each procedure is performed with the necessary measure and precision for each case, so the methods may vary according to the clinic of each patient. In any case, we perform an exhaustive follow-up during each stage of this process.
