Yellow body in the right ovary during pregnancy

author: doctor Kuznetsov MA

The yellow body can appear either in the left or in the right ovary and not necessarily during pregnancy. This education appears in the second phase of the menstrual cycle and exerts its influence depending on the situation.

If the pregnancy has not occurred, then this Graafovy vesicle undergoes involution - it turns into a connective tissue scar. This action comes after two weeks of his active work on the preparation of the endometrium of the uterus - the mucosa for attachment and nutrition of the embryo.

The yellow body is formed in the ovary instead of the follicle that has completed ovulation. It temporarily produces sex hormones - progesterone and estrogen. Progesterone is needed to maintain pregnancy, especially at the beginning, when the placenta itself can not yet produce the required amount of this hormone. Therefore, up to 12 weeks, this work is performed by a yellow body. On ultrasound it looks like a non-uniform rounded yellow formation of soft consistency, however, the hormonal functioning of this organ can be diagnosed only in the laboratory. For this, certain tests must be submitted.

Errors in the second phase of the menstrual cycle of the luteal phase are associated with a deficiency of the yellow body or in general its absence. The lack of a yellow body in turn provokes a deficiency of progesterone - the most important component of the hormonal system during pregnancy.

Left ovary with yellow body

author: doctor Krivega M.S.

Each woman has two ovaries, in which a few thousand (about 300 thousand) ovules are in the inactive state still in the pre-natal period. Since the age of 13, when the first menstruation begins, one or two (which happens less often) eggs mature. A mature egg leaves a small cavity, the follicle where it ripens and enters the uterine cavity in search of a sperm (which, by the way, should not be reached by one, but in several thousands accompanied by fertilization). This process of egg release is called ovulation. Every month, only one ovary is working on the maturation of the egg, but there are menstrual cycles, when ovulation does not occur at all.
