TRT testicular atrophy




Strategy for clinicians

To maintain fertility in men with hypogonadism prescribed testosterone, Lipshultz said, clinicians should first insist on a semen analysis before beginning testosterone treatment.

Patients need to realize that 2% of all men are sterile,” Lipshultz said.
“We need to know where the individual is before we introduce testosterone because our endpoint may not be able to be any better than pre-treatment level.”

If the man desires a future pregnancy, the clinician should prescribe hCG concurrent with testosterone therapy, typically at 500 U subcutaneous three times per week or 1,500 U once weekly if the patient wishes only to prevent testicular atrophy.
The patient should cycle off of testosterone twice yearly, at a rate of 3,000 U three times per week for 4 weeks, adding 25 mg daily clomiphene therapy during that period, Lipshultz said. However, for men desiring a pregnancy, 3,000 U hCG three times per week should be prescribed in addition to clomiphene therapy. Clinicians should check the patient’s follicle-stimulating hormone (FSH) level and conduct a semen analysis after 4 months for men desiring pregnancy; if the FSH level is not sufficiently elevated, the clinician should discontinue clomiphene and instead introduce FSH concurrent with the hCG, he said.

“To date, we have not had any patients who did not return to baseline,” Lipshultz said, referring to the regimen.by Regina Schaffer
 

Conclusions: Our results reiterate that FSH in combination with hCG may be considered as an alternative to combination hCG and clomiphene in the treatment of testosterone-induced azoospermia. FSH and hCG dual therapy may result in the more rapid recovery of sperm to the ejaculate being three times faster in the FSH group. Additionally, patients who have failed dual therapy with hCG and clomiphene should be considered for subsequent FSH.

Thanks for all the info, will be diving into that
 
You should have looked into this deeper and had a thorough evaluation before jumping on anything.

Any man that plans on using exogenous testosterone and is interested in preserving/maintaining fertility should have a baseline semen analysis done.

Many men on trt can preserve/maintain fertility let alone prevent/minimize testicular atrophy with the addition of hCG.


*Sensibly, all men wishing to preserve fertility while on TTh should obtain a baseline SA. During the initial consultation, it is also important to identify the patient’s goals with regard to the timing of the pregnancy (Table 1).


























Figure 2: Ontogeny of the evolution of testicular volume from birth to adulthood. Seminiferous cords (Sertoli cells + germ cells) are the main component of the testes. From birth and during the prepubertal period (i. e., until 9–14, Tanner stage 1), the volume of seminiferous cords is determined by Sertoli cells, whereas germ cell proliferation determines testicular volume during puberty (i. e., Tanner stages 2 to 5) (adult spermatogenesis).

Understanding Your Hormones

Estradiol (E2)

A form of estrogen produced from testosterone. Important for bone health, mood, and libido. Too high can cause side effects; too low can affect well-being.

DHT

Dihydrotestosterone is a potent androgen derived from testosterone. Affects hair growth, prostate health, and masculinization effects.

Free Testosterone

The biologically active form of testosterone not bound to proteins. Directly available for cellular uptake and biological effects.
