A 28-year-old man preparing to start TRT asks whether he should use HCG or enclomiphene now, cycle fertility medications, or wait until he is ready to have children.

Dr. O’Connor explains why testosterone numbers alone are not enough and asks about symptoms, medical conditions, varicoceles, previous fertility, children, and other factors that should be evaluated before committing to lifelong TRT.

The evidence for using HCG concurrently with testosterone is reviewed, including the possibility that it may preserve some testicular function while acknowledging that long-term data are limited.

Dr. O’Connor discusses the practical challenges of remaining on HCG with TRT for years, including repeated injections, cost, refrigeration, compliance, eventual downregulation, and the option of semen analysis or sperm banking before treatment.

For men years away from having children, Dr. O’Connor describes the common approach of using the lowest sustainable TRT dose, monitoring health, and addressing fertility when conception becomes an immediate goal.

Dr. O’Connor explains transitioning off testosterone when fertility becomes the priority and using HCG to stimulate testicular function, with clomiphene, enclomiphene, or FSH-based fertility medications considered in selected cases.
Video Summary
A 28-year-old man considering TRT asks how to preserve fertility before having children in five to ten years. Dr. O’Connor reviews his earlier use of Anavar, Winstrol, testosterone, Dianabol, HCG, and testosterone-boosting supplements, along with his current low-normal testosterone levels, normal LH and FSH, and gynecomastia following HCG use.
The discussion focuses on whether beginning testosterone while taking HCG can preserve testicular function and future fertility. Dr. O’Connor explains that testosterone will eventually suppress the hypothalamic-pituitary-gonadal axis and may cause testicular atrophy, while the available long-term evidence that concurrent HCG can prevent this is limited. He also discusses semen analysis and sperm banking before TRT, the practical difficulty of maintaining long-term HCG injections, and why simply adding multiple SERMs or other fertility drugs to testosterone is not a proven strategy.
For men who begin TRT years before they plan to conceive, Dr. O’Connor describes another approach in which testosterone is discontinued when fertility becomes the priority and HCG is used to stimulate testicular function, sometimes with clomiphene or enclomiphene. More advanced fertility treatment may involve FSH-based medications such as Gonal-F or HMG when necessary, and he emphasizes that individual fertility history, semen analysis, underlying medical conditions, mood, and the partner’s fertility all influence the plan.

Drug
Description
Testosterone
The member is considering beginning long-term testosterone therapy but is concerned about having children in five to ten years. Dr. O’Connor explains that exogenous testosterone suppresses the hypothalamic-pituitary-gonadal axis and can reduce testicular function and fertility over time.
Human Chorionic Gonadotropin (HCG)
HCG is the primary fertility medication discussed because the member wants to know whether he should use it continuously with TRT or wait until he wants children. Dr. O’Connor explains that concurrent HCG may preserve some testicular function but says the long-term evidence is limited and later describes HCG as a central medication when transitioning off testosterone to pursue fertility.
Clomiphene
Clomiphene is discussed as a selective estrogen receptor modulator that may be combined with HCG after testosterone is discontinued for fertility restoration. Dr. O’Connor distinguishes this from routinely adding clomiphene while remaining on testosterone and describes the off-testosterone combination as a way to increase LH and FSH signaling.
Enclomiphene
The member was considering enclomiphene before deciding whether to start TRT, and Dr. O’Connor later discusses it as an alternative to clomiphene during fertility restoration. He notes that it may stimulate central LH and FSH signaling but also cautions that evidence and individual tolerability must be considered.
Gonal-F
Gonal-F is discussed as a recombinant FSH-based fertility medication that may be combined with HCG in more advanced fertility treatment. Dr. O’Connor presents it as a specialized option used with fertility urology when additional stimulation of spermatogenesis is needed.
Human Menopausal Gonadotropin (HMG)
HMG is mentioned as another fertility medication with FSH activity that may be used when more intensive stimulation of sperm production is required. Dr. O’Connor discusses it as an advanced option rather than something every man starting TRT automatically needs.

Description
Infertility
Future infertility is the member’s primary concern because he plans to have children after several years of testosterone therapy. Dr. O’Connor explains that TRT suppresses the reproductive axis and may impair sperm production, making fertility planning an important consideration before a young man commits to long-term testosterone.
Anabolic Steroid-Induced Hypogonadism
The member previously used several anabolic steroids and now has low-normal testosterone despite normal LH and FSH. Dr. O’Connor raises anabolic steroid-induced hypogonadism as a possible working diagnosis while emphasizing that symptoms, medical history, examination, and other potential causes would still need evaluation.
Testicular Atrophy
Dr. O’Connor explains that suppression of the hypothalamic-pituitary-gonadal axis from testosterone can eventually lead to testicular atrophy. This matters particularly for a young man beginning TRT who wants to preserve enough testicular function to father children years later.
Gynecomastia
The member reports developing gynecomastia after previously using HCG. Dr. O’Connor later notes that combining HCG with testosterone can increase endogenous and exogenous testosterone exposure and may also produce additional estrogen-related effects such as puffiness and edema.
Erectile Dysfunction
Dr. O’Connor describes men who experience loss of libido and erectile dysfunction after stopping long-term testosterone because their endogenous testosterone remains suppressed. This is one reason he discusses an active fertility-transition strategy rather than simply stopping testosterone and waiting for recovery.
Mood Disorders
Mood disorders become important when clomiphene or enclomiphene is added during fertility restoration because Dr. O’Connor has seen some men experience significant emotional changes while also coming off testosterone. He emphasizes extra caution in men with preexisting mood problems or suicidal thoughts.
Key Takeaways
- A young man considering TRT should address future fertility before starting because testosterone can suppress testicular function and sperm production.
- Concurrent HCG may help preserve testicular function during TRT, but Dr. O’Connor emphasizes that the long-term evidence is limited and downregulation and compliance remain concerns.
- Semen analysis and sperm banking before TRT are options for men who want a clearer picture of their baseline fertility before beginning treatment.
- Adding multiple fertility medications while remaining on testosterone is not the same as having a proven long-term strategy for preserving fertility.
- One common approach is to remain on a sustainable TRT regimen until fertility becomes an immediate priority and then transition off testosterone to fertility-directed treatment.
- HCG alone or combined with clomiphene, enclomiphene, or FSH-based therapy may be used during fertility restoration depending on the individual man’s response and fertility needs.
