Did you know that the hormones involved in menstrual cycles (ovarian function) are also involved in s***m health (testicular function)?
Yes it’s true (and it’s super cool) 😎
S***m health is generally dependent on testosterone production. Testosterone production is influenced by hormonal crosstalks made possible by the interactions (mainly) between the brain and the te**es.
We call this feedback system the Hypothalamic-Pituitary-Gonadal/Testicular (HPG or HPT) Axis.
Similar to the hormonal feedback system in menstrual cycles, in the brain, the pulsatile release of gonadotropin-releasing hormone (GnRH) by the hypothalamus stimulates the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) made by the anterior pituitary gland.
LH and FSH also act on the testicular cells, the Leydig cells, and Sertoli cells – via the process of steroidogenesis.
The HPG axis does not exist in a vacuum, as it can be affected by other factors such as metabolic hormones (e.g. insulin, leptin), sleep and stress regulation (e.g. cortisol, melatonin), and external factors (e.g. exposure to endocrine-disrupting chemicals).
This is why it is important to assess your unique health history in order to understand what may be affecting your fertility.
