What is a Menstrual Cycle Hormone Chart?
Understanding the female menstrual cycle can be complex, given its intricate nature, the many hormones involved, many phases, and interwoven feedback mechanisms. Rather than writing down the hormone variations over the menstrual cycle, it can be a lot easier to understand a visual representation. Hence, our Menstrual Cycle Hormone Chart is designed as a reliable, go-to visual reference.
This visual aid depicts the ebb and flow of gonadotropic and ovarian hormones throughout a standard 28-day cycle, emphasizing essential events like ovulation and menstruation.
It's worth noting that this printable chart illustrates a standard 28-day cycle for simplicity. However, it's imperative to remember that uterine and ovarian cycles exhibit substantial variability between individuals. While some may adhere to a regular 28-day rhythm, others may experience processes that are notably longer, shorter, or less uniform (Ernst & Watson, 2023).
So, if you need to refresh your understanding of the menstrual cycle or help educate your patients on the changes in their reproductive hormones throughout their cycles, you're in the right place.
How Does this Menstrual Cycle Hormone Chart Work?
This Menstrual Cycle Hormone Chart depicts the concentrations of the most influential female reproductive hormones and their fluctuations over 28 days, or one complete ovarian/uterine cycle.
The chart is split into two line graphs: gonadotropic hormone levels, specifically FH and LSH, and ovarian hormone concentrations encompassing estradiol, inhibin, and progesterone. This division allows for a clear visual representation of the changes in each hormone.
It's important to note that this graph is designed to be a stylized representation of the relative hormonal changes and is not an entirely accurate resource for exact concentration values.
Menstrual Cycle Hormone Chart Example (sample)
To see how this Menstrual Cycle Hormone Chart can help you provide valuable context for your patients’ hormone test results, just take a look at our example Menstrual Cycle Hormone Chart. This example shows how a seemingly high E2 result can be placed in the context of the natural fluctuations over the course of the menstrual cycle.

When Would you use This Chart?
This chart serves a dual purpose: it is a valuable tool for revision for anyone seeking to review the vital hormonal changes in the menstrual cycle, and it also serves as an instructive aid for patients.
Understanding the fluctuations in hormones throughout the menstrual cycle can be a challenging concept to grasp. Thus, having a structured resource readily available can be a great asset in elucidating more intricate hormonal principles.
This resource can help any patients with an interest in the menstrual cycle, whether they are initiating birth control, exploring fertility, or simply seeking educational or illustrative materials. While we have incorporated critical milestones like ovulation and menstruation, there is ample space for annotations or additional notes to elaborate on any concepts you deem necessary when using this menstrual cycle hormone chart as an explanatory tool.
A wide range of practitioners stand to benefit from having this resource at their disposal. These could include:
- Medical, nursing, or health sciences students
- General practitioners
- Fertility Specialists
Research & Evidence
Extensive research has been conducted into the fluctuations of female reproductive hormones throughout the ovarian and uterine cycles, drawing from human and animal model investigations. The underlying mechanisms driving these hormonal shifts, as illustrated in this resource, have been the subject of study over recent decades. They are predominantly regulated by hormones in the hypothalamus, pituitary, and ovaries (Taylor et al., 2020).
A crucial feedback loop involves the suppression of FSH and LH by elevated levels of estrogen and progesterone, particularly evident during the follicular phase of the ovarian cycle. However, when estrogen levels reach a critical threshold, this feedback loop switches from negative to positive, culminating in a surge of LH that ultimately triggers ovulation in the late follicular phase (Hawkins & Matzuk, 2008).
This dynamic is observable in our menstrual cycle hormone chart, where there is a notable spike in LH following the peak in estrogen levels just before ovulation. The chart portrays a cycle in which fertilization does not occur, and consequently, the corpus luteum, responsible for secreting estrogen and progesterone, is reabsorbed, forming the scar-like corpus albicans. The subsequent decline in ovarian hormones initiates menstruation (Ernst & Watson, 2023).
