Fertility preservation on therapy
Exogenous testosterone suppresses the body's own production and, with it, spermatogenesis. If you intend to conceive now or later, this must be part of the conversation before therapy begins — not after.
What a provider evaluates
- Current and future fertility intentions
- Baseline LH, FSH and, where indicated, semen analysis
- Whether a non-suppressive approach is more appropriate than testosterone
What treatment may involve
- Enclomiphene, which raises endogenous testosterone without suppressing the axis
- hCG or gonadorelin alongside testosterone in a provider-directed protocol
- Referral for semen analysis and specialist input where appropriate
Whether any of these is appropriate is determined by a licensed provider after reviewing your history and laboratory results.
Medications a provider may consider
Enclomiphene
Enclomiphene raises the body's own testosterone rather than replacing it. Learn how it works, who providers consider it for, and how it compares to TRT.
Gonadorelin
Gonadorelin is a GnRH analogue sometimes used alongside testosterone therapy. Learn what it is and what a provider assesses before prescribing.
Testosterone cypionate
Testosterone cypionate is a long-acting injectable form of testosterone. Learn how it is dosed, what monitoring it requires, and who a provider may consider it for.
Questions about fertility preservation on therapy
Does testosterone therapy affect fertility?
Yes. Exogenous testosterone suppresses the hormonal signals that drive sperm production, and this can reduce or halt spermatogenesis while on therapy. If you intend to conceive now or in future, raise it before starting. Providers may consider alternatives such as enclomiphene, which raises endogenous testosterone without the same suppressive effect, or adjunct protocols alongside testosterone.
What is enclomiphene?
Enclomiphene is an oral selective estrogen receptor modulator that acts at the pituitary to increase LH and FSH, which in turn stimulate the testes to produce more testosterone. Because it works through the body's own axis rather than replacing testosterone from outside, it does not carry the same suppressive effect on sperm production. It is compounded, is not FDA-approved for this use, and is prescribed at provider discretion.
