Fertility Panel
Essential for AAS users concerned about fertility. Steroid use suppresses LH, FSH, and sperm production. This panel tracks both hormonal signals and direct semen parameters to assess reproductive function.
When to Test
At least 3 months after stopping all AAS (sperm cycle is ~74 days). Semen analysis after 2-5 days abstinence.
Testing Frequency
Every 3 months during recovery. Consider baseline semen analysis before first cycle.
Markers in This Panel(10)
LH
HormonesLuteinising hormone drives testosterone production and is suppressed by all AAS.
Ref: 1.5 – 9.3 IU/L
FSH
HormonesFollicle-stimulating hormone drives spermatogenesis. Must recover for fertility.
Ref: 1.5 – 12 IU/L
Testosterone
HormonesIntratesticular testosterone (reflected by serum levels off-cycle) is needed for sperm production.
Ref: 8 – 30 nmol/L
Estradiol
HormonesEstrogen is needed for spermatogenesis; crashed estrogen impairs fertility.
Ref: 40 – 160 pmol/L
Prolactin
HormonesElevated prolactin (from 19-nors or stress) suppresses GnRH and impairs fertility.
Ref: 45 – 375 mIU/L
SHBG
HormonesAffects free testosterone and estradiol balance, both important for fertility.
Ref: 10 – 70 nmol/L
Sperm Concentration
FertilityDirect measure of sperm production. Often zero on AAS; should recover post-PCT.
Ref: 16000000 – 999000000 /mL
Total Motility
FertilityPercentage of moving sperm; critical for natural conception.
Ref: 42 – 100 %
Progressive Motility
FertilitySperm moving forward (not in circles); the most important motility measure.
Ref: 30 – 100 %
Sperm Morphology
FertilityPercentage of normally shaped sperm; low morphology reduces fertility.
Ref: 4 – 100 % Normal Forms
