Lutealne

Lutealne is a term that can refer to several related concepts primarily within biology and medicine, most commonly associated with the menstrual cycle and pregnancy. In the context of the menstrual cycle, the luteal phase is the second half of the cycle, following ovulation. During this phase, the ruptured follicle in the ovary transforms into a structure called the corpus luteum. This corpus luteum then produces progesterone, a crucial hormone that prepares the uterine lining (endometrium) for a potential pregnancy. If fertilization does not occur, the corpus luteum degenerates, leading to a drop in progesterone and the onset of menstruation.

The term lutealne can also be used adjectivally to describe things related to the corpus luteum, such as lutealne function or lutealne insufficiency. Lutealne insufficiency refers to a condition where the corpus luteum does not produce enough progesterone, which can contribute to infertility or early pregnancy loss. Diagnosis and treatment of lutealne issues often involve hormonal assessments and therapies aimed at supporting progesterone levels. The proper functioning of the luteal phase is essential for reproductive success in many mammalian species.
