Summary Biological Factors Influencing Male and Female Fertility

Unlock the foundations of human reproduction with a visual guide that simplifies the complex science behind fertility. A mind map on What Causes Fertility will show the key biological, hormonal, and physiological factors that enable successful reproduction in both males and females. It will outline the role of the hypothalamic-pituitary-gonadal (HPG) axis and how hormones such as GnRH, LH, FSH, estrogen, progesterone, and testosterone regulate ovulation, spermatogenesis, and reproductive cycles. The mind map will highlight anatomical factors like ovarian function, sperm quality, and uterine receptivity, as well as external influences such as age, lifestyle, stress, and environmental exposures. It will also cover clinical aspects, including fertility assessments and common causes of infertility (e.g., hormonal disorders, PCOS, low sperm count), giving a clear and structured overview of what supports or impairs human fertility.
