What role does ovulation play in the menstrual cycle"?
Ovulation is the release of an egg from the ovary, which typically occurs around the middle of the menstrual cycle. It is a crucial step in the menstrual cycle as it is necessary for fertilization to occur. If the egg is not fertilized, it will disintegrate and be shed during menstruation.
How does the LH hormone impact the menstrual cycle?
The LH hormone, or luteinizing hormone, plays a crucial role in the menstrual cycle by triggering ovulation. When LH levels surge, typically around the middle of the cycle, it causes the mature egg to be released from the ovary. This release of the egg is essential for fertility and the continuation of the menstrual cycle.
What role does LH play in the menstrual cycle?
Luteinizing hormone (LH) plays a crucial role in the menstrual cycle by triggering ovulation, the release of an egg from the ovary. LH surge occurs around the middle of the menstrual cycle, causing the mature egg to be released and making conception possible.
What happens at the end of a menstrual cycle?
At the end of a menstrual cycle, the unfertilized egg is either absorbed by the body or expelled during menstruation. The lining of the uterus, which thickened in preparation for a possible pregnancy, sheds as menstrual bleeding. This marks the start of a new menstrual cycle.
How can a sperm influence the menstrual cycle?
Sperm does not directly influence the menstrual cycle. The menstrual cycle is regulated by hormones like estrogen and progesterone that are produced by the ovaries. Sperm's role is to fertilize an egg if present, which can lead to pregnancy but does not impact the regularity of the menstrual cycle.
