luteaalne

Luteeelne refer to the second half of the menstrual cycle, specifically the period after ovulation and before the onset of menses. It is a crucial phase in the female reproductive cycle and plays a significant role in preparing the uterus for potential pregnancy.

During the luteeelne phase, the empty follicle in the ovary collapses and forms a corpus luteum, which secretes the hormone progesterone. Progesterone has several functions, including preparing the uterine lining for implantation of a fertilized egg, regulating the menstrual cycle, and maintaining pregnancy.

If pregnancy does not occur, the corpus luteum degenerates, leading to a drop in progesterone levels and a subsequent start of menstruation. This marks the end of the luteeelne phase and the beginning of a new menstrual cycle.

The luteeelne phase is characterized by several physical and hormonal changes, including increased body temperature, breast tenderness, and mood swings. Some women may also experience cramping or spotting during this phase.

Luteeelne phase defects, such as luteal insufficiency or inadequate progesterone production, can affect the menstrual cycle and fertility. In these cases, women may experience irregular periods, failure to conceive, or early miscarriage.

A healthy luteeelne phase is essential for maintaining a regular menstrual cycle and ensuring pregnancy.
