What is the Origin of Fertility Preservation during TRT?

This is a specialized clinical protocol developed from the combined fields of reproductive endocrinology and male fertility. The necessity arose directly from the widespread use of exogenous testosterone, which inadvertently causes iatrogenic secondary hypogonadism and subsequent infertility. It reflects a modern commitment to comprehensive patient care that addresses quality of life and future reproductive planning.

What is the Mechanism of Fertility Preservation during TRT?

The primary mechanism involves administering agents that stimulate the HPG axis, such as human chorionic gonadotropin (hCG) or selective estrogen receptor modulators (SERMs), often concurrently with or instead of standard testosterone therapy. These agents mimic the action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for stimulating Leydig cells to produce testosterone and Sertoli cells to support sperm production, thus overriding the suppressive negative feedback from the exogenous testosterone.

Fertility Preservation during TRT

Meaning

Fertility Preservation during TRT refers to the clinical strategy and pharmacological interventions employed to maintain spermatogenesis and reproductive capacity in men undergoing Testosterone Replacement Therapy (TRT). TRT, while effective for hypogonadism symptoms, often suppresses the hypothalamic-pituitary-gonadal (HPG) axis, leading to testicular atrophy and functional infertility. This preservation strategy is crucial for men who desire future fatherhood.
