Without ovaries can you menstruate?


One of the aspects that most doubts raises the question of women in terms of women's health is the menstruation cycle, especially when anomalies occur in this process. One of the clearest examples is the lack of menstruation or its irregularity, which can be caused by various factors and, to solve them, it is necessary to go to a specialist.

Without ovaries can you menstruate

One of the most frequently asked questions that can be generated is related to the ovulation process. Menstruation and ovulation are intimately related and it is generally thought that if there are no ovaries or no eggs you cannot menstruate. It is true that in most cases it is so, but there are times when there are no eggs and menstruation does occur. There are some reasons that can lead you to this situation, so in we solve your question: without ovaries can you menstruate?

What is and how does the menstrual cycle work?

In order for us to correctly explain the reasons why without eggs or ovaries there are cases in which you can menstruate, it is necessary that you first know in detail the process of ovulation and the menstrual cycle and how they develop. Both are carried out by the woman's internal sexual organs, which are the ovaries, fallopian tubes, uterus and vagina. The action of hormones in these processes must also be taken into account.

The menstrual cycle usually covers about 28 or 29 days. 14 days after ending menstruation, one of many eggs that contains the ovary matures and leaves it to the Fallopian Tubes, where it reaches the uterus that, to prepare a possible fertilization of the egg, thickens its lining, where the placenta would develop. In the maturation of the egg and the increase in the thickness of the wall of the uterus, hormones have a very important role, which help both to be produced.

If the egg that travels through the fallopian tubes to the uterus is fertilized, the woman becomes pregnant and begins the process of gestation and development of the fetus. But if no sperm reaches the egg, menstruation begins. The egg will be discarded, as will the entire endometrial wall of the uterus that was preparing to host the egg and generate the placenta.

Can you menstruate without ovaries? – here the answer

We have previously highlighted that hormones have a very important role in menstruation. The presence of the ovaries, although they do not even produce eggs, cause the release of certain hormones that cause the endometrium in the wall of the uterus to thicken, preparing to welcome the egg and becoming the placenta. When there is no egg, or it is not fertilized, it separates from the uterine wall and falls, causing bleeding.

This leads us to the conclusion that if we do not have ovaries, these hormones are not produced because we do not produce eggs and, therefore, menstruation will not occur. That is why it is very important that, if any type of bleeding occurs without the presence of ovaries, you go immediately to the specialist.

In the event that you have an ovary, even if it does not produce eggs, you can menstruate, since the presence of these hormones does occur. It is not even necessary that you have a complete ovary, if there was any remainder of ovarian tissue, it is possible that you generate the production of hormones that cause the development of the endometrium and, therefore, menstruation occurs.

In addition, there are also situations in which there is menstruation without ovulating, as we will see below.

Can you have menstruation and not ovulate?

After explaining the whole process of ovulation and menstruation, it is easy to discover why, although there are no ovaries or that egg is produced that is later discarded, there can be menstrual bleeding.

Although the most common is that bleeding does not occur if there are no ovaries or eggs, because the egg has not matured correctly or has not broken the follicle and has not been released, bleeding can occur, because menstruation does not depend exclusively on an unfertilized egg, it also depends on the endometrial wall of the uterus, that increases its size to receive that fertilized egg, a process that is also developed by hormones.

Therefore, it is possible that there is that thickened endometrium that needs to be expelled from the uterus. The menstrual flow is composed, in addition to the endometrium, of the blood generated by the rupture of those small blood vessels that supply the future placenta and that rupture when the endometrium separates from the uterus. Normally an amount of between 50 and 70 cl of blood is lost in this process. This eggless (or anovular) menstruation is also called dysfunctional uterine hemorrhage.

Other causes of menstrual cycles without ovulation

Menstrual cycles without ovulation, or anovular menstrual cycles, can occur for several reasons:

  • A problem or alteration at the level of sex hormones that control the maturation and release of the egg from the ovary.
  • The non-release of the egg, because the follicle does not open, despite a correct maturation
  • Polycystic ovary syndrome, in which small cysts appear on the ovaries that hinder the correct performance of their functions, producing irregular menstruations and ovulations.
  • Weight disorders such as obesity, anorexia or bulimia, since hormones are affected in these alterations.
  • Excessive stress or anxiety.
  • Shocks or very important alterations at an emotional level.
