Chorionic Gonadotrophin Injection IP (EUTRIG-HP 5000 IU) Vial

Most hormonal medications replace what the body isn’t making. HCG does something more elegant — it tells the body to make more of it itself. As a near-identical structural analogue of luteinising hormone (LH), human chorionic gonadotrophin tricks the testes into producing testosterone and sperm as though the brain’s own LH signal had fired. The body does the work. HCG just delivers the instruction.

That distinction matters enormously in practice — particularly for men who need testosterone support but can’t afford to sacrifice fertility in the process.

The LH Mimicry Mechanism

In the male reproductive system, LH from the pituitary gland stimulates Leydig cells in the testes to produce testosterone. When exogenous testosterone is introduced — through TRT injections, gels, or patches — the pituitary detects high testosterone levels and suppresses both LH and FSH output. The testes, no longer receiving the LH signal, reduce their own testosterone and sperm production. Testicular atrophy and azoospermia are well-documented consequences of testosterone monotherapy in men who go unsupported.

HCG bypasses this suppression. Because it acts directly on testicular Leydig cells — not through the pituitary — it stimulates intratesticular testosterone production regardless of whether the brain’s own LH signal has been shut down. Research shows that low-dose HCG co-administered with testosterone prevents the azoospermia that occurs in roughly 40% of men on testosterone monotherapy. It also maintains testicular volume and preserves the intratesticular testosterone levels essential for sperm production.

Three Distinct Uses — One Mechanism

Men on TRT: For men taking testosterone who want to preserve fertility, prevent testicular atrophy, or simply maintain the body’s own hormonal signalling alongside exogenous testosterone, HCG is the standard co-medication. It keeps the testes active and functioning while testosterone levels are elevated externally.

Male Hypogonadism and Fertility: For men with hypogonadotrophic hypogonadism — where the problem is insufficient LH signalling from the pituitary rather than a testicular failure — HCG can restore testosterone levels and sperm production without requiring exogenous testosterone at all. A 2022 study of men with hypogonadal symptoms showed HCG monotherapy improved libido in 80%, energy in 79%, and erectile function in 86% of participants.

Female Fertility — The Trigger Shot: In IVF and assisted reproduction cycles, HCG 5000 IU is used as the “trigger shot” — administered when follicles reach maturity to initiate final egg maturation and trigger ovulation approximately 36 to 40 hours later. The timing of oocyte retrieval is scheduled around this window. It’s also used after embryo transfer to support the corpus luteum and progesterone production during early implantation.

EUTRIG-HP 5000 IU — Indian Pharmacopoeia Standard

The IP designation confirms this meets the Indian Pharmacopoeia quality standard for purity, potency and dosage consistency — the same quality benchmark that underpins India’s role as one of the world’s largest pharmaceutical exporters.

HCG injection should be administered intramuscularly or subcutaneously. In women, there is a risk of ovarian hyperstimulation syndrome (OHSS) — seek medical advice if you experience significant abdominal pain, bloating or rapid weight gain after injection. HCG will cause a false positive on a pregnancy test for up to two weeks after injection — wait before testing. Not for use if LH levels are already elevated above 20 IU/L in men.
