What is the Follicular Phase?
The follicular phase is the first part of the menstrual cycle, beginning on the first day of menstruation and ending at ovulation. During this phase, several follicles in the ovary mature and get ready to release an egg.
When Does the Follicular Phase Occur in the Menstrual Cycle?
The follicular phase starts on the first day of your period and lasts until ovulation. It can vary in length, generally between 10 to 16 days, and it primarily prepares your body for potential pregnancy by maturing an egg in the follicles of your ovaries.
How Can I Track the Follicular Phase?
The follicular phase can be tracked by noting the first day of your period (which is also the start of the menstrual cycle) until the day of ovulation. Ovulation prediction methods such as monitoring basal body temperature, checking cervical mucus, or using ovulation predictor kits can help identify the transition from the follicular phase to ovulation.
Which Hormones are Involved in the Follicular Phase?
The follicular phase involves the rise and fall of several hormones:
- Follicle-stimulating hormone (FSH): FSH is secreted by the pituitary gland at the start of the follicular phase, stimulating the ovaries to develop follicles.
- Estrogen: As the follicles mature, they release estrogen, which stimulates the growth of the uterine lining and signals the pituitary gland to decrease FSH production and increase luteinizing hormone (LH).
How Can the Follicular Phase Impact Emotional and Mental Health?
During the follicular phase, the increasing estrogen levels can have a positive effect on mood and energy levels. However, for some women, these hormonal changes may also contribute to symptoms of anxiety or mood swings.
