The global assisted reproductive technology (ART) field is rapidly
advancing toward long-acting, patient-centric protocols, with long-acting
follicle-stimulating hormone (FSH) formulations reshaping treatment paradigms.
Amid this evolution, Human chorionic gonadotropin (hCG) retains its
irreplaceable role as a synergistic agent, complementing the efficacy of
long-acting FSH to optimize follicular maturation and pregnancy outcomes. Beyond
its traditional function as an ovulation trigger, Human chorionic gonadotropin
now plays a tailored role in modern ART regimens, addressing unmet needs for
treatment simplicity and efficacy consistency—key priorities for both clinicians
and infertile couples.
The synergistic mechanism between Human chorionic gonadotropin and
long-acting FSH stems from their complementary biological actions. Long-acting
FSH, engineered via CTP fusion protein technology, delivers sustained hormone
release for 7 days, eliminating daily injections and stabilizing follicular
development1. Human chorionic gonadotropin, which mimics
luteinizing hormone (LH) activity, provides the critical final maturation signal
for follicles primed by long-acting FSH. Clinical data shows this combination
not only maintains comparable oocyte quality and pregnancy rates to traditional
regimens but also reduces the risk of ovarian hyperstimulation syndrome (OHSS),
with no severe cases reported in multi-center trials1. This
synergy balances the convenience of long-acting therapy with the precision of
targeted follicular maturation.

Human chorionic gonadotropin also extends its synergistic value to male
infertility treatment, particularly when combined with FSH in hypogonadotropic
hypogonadism cases. For patients with non-obstructive azoospermia, a regimen of
Human chorionic gonadotropin (1500-2000 IU, 2-3 times weekly) plus FSH (75-150
IU, 3 times weekly) restores spermatogenesis in approximately 70% of cases
within 6-12 months2. This combination targets both
testosterone secretion (via LH mimicry) and spermatogenic tubule development,
addressing the root causes of hormone-deficient male infertility. Notably, this
therapeutic approach aligns with the growing trend of comprehensive ART
solutions that address both male and female factors.
Kangyuan integrates the synergistic potential of Human chorionic
gonadotropin into its comprehensive ART product portfolio, supporting modern
long-acting protocols and male infertility treatments. Our Human chorionic
gonadotropin products adhere to strict global quality standards (USP, EP,
Chinese Pharmacopoeia), ensuring consistent bioactivity for reliable synergistic
effects with FSH formulations. We offer flexible dosages (1000 IU, 2000 IU
vials) to accommodate personalized regimens, from female ovulation triggering in
long-acting FSH cycles to male spermatogenesis induction. Advanced purification
technologies guarantee low impurity levels, minimizing adverse reactions and
enhancing treatment safety.
As ART shifts toward long-acting, personalized therapies, Human chorionic
gonadotropin’s synergistic role becomes increasingly pivotal for optimizing
treatment outcomes. Kangyuan remains at the forefront of this evolution,
providing high-quality Human chorionic gonadotropin that complements modern FSH
regimens and addresses both male and female infertility needs. Our professional
team offers clinical guidance on synergistic protocol design, helping clinics
streamline treatment processes and improve patient experiences. Whether you are
integrating long-acting FSH into your practice or seeking effective male
infertility solutions, Kangyuan is your trusted partner. Contact us today to
