HCG (human chorionic gonadotropin) injections are commonly used in fertility treatments to induce final egg maturation and ovulation, or to support early pregnancy. In IVF (in vitro fertilisation) cycles, hCG is given to trigger final egg maturation and allow for timely egg retrieval. In IUI (intrauterine insemination) cycles, hCG helps synchronise ovulation with the insemination procedure.
HOW hCG INJECTIONS ARE USED IN FERTILITY TREATMENTS
-
Triggering Ovulation:
hCG mimics the natural LH surge, inducing final egg maturation and follicle rupture, releasing the eggs for fertilisation. -
Timing of Fertility Procedures:
In both IVF and IUI, hCG injections help synchronise the release of mature eggs with the timing of egg retrieval or insemination, optimising the chances of success. -
Supporting Early Pregnancy:
hCG also plays a role in supporting the early stages of pregnancy by stimulating the production of progesterone, which is crucial for maintaining the uterine lining. -
Timing of Insemination or Egg Retrieval:
In IUI, the injection is typically given about 36 hours before the scheduled insemination. In IVF, it’s administered about 36 hours before egg retrieval.
POTENTIAL SIDE EFFECTS
-
Ovarian Hyperstimulation Syndrome (OHSS):
A possible but rare side effect where the ovaries become swollen and painful due to the hCG injection. -
False Positive Pregnancy Tests:
hCG can be detected in urine for several days after injection, potentially causing a false positive pregnancy test. It is recommended to wait about 14 days after the hCG injection before taking a home pregnancy test. -
Mild Side Effects:
These may include pain or cramping at the injection site, bloating, or nausea.
IMPORTANT CONSIDERATIONS
-
Individualised Treatment Plans:
Fertility treatments, including the use of hCG injections, are tailored to each individual’s specific needs and medical history. -
Monitoring:
Patients undergoing fertility treatments with hCG injections are closely monitored by their healthcare provider for any potential side effects or complications. -
Consultation with a Specialist:
It is essential to discuss any concerns or questions regarding hCG injections with a fertility specialist.
