Summary
Clomiphene citrate (CC) ovulation induction does not alter endometrial leukemia inhibitory factor (LIF) levels in women with unexplained infertility. This finding suggests CC is safe for endometrial health during infertility treatment.
Area of Science:
- Reproductive Endocrinology
- Infertility Research
Background:
- Leukemia inhibitory factor (LIF) is crucial for human embryo implantation.
- Unexplained infertility affects a significant portion of couples seeking fertility treatment.
- Clomiphene citrate (CC) is a common ovulation induction agent.
Purpose of the Study:
- To compare endometrial LIF levels between spontaneous and CC-induced ovulation cycles.
- To assess the impact of CC on endometrial receptivity markers in unexplained infertility.
Main Methods:
- Endometrial biopsies were collected 7 days post-ovulation in spontaneous and CC-induced cycles.
- LIF levels were quantified using the ELISA method.
- Patients underwent two consecutive cycles, one spontaneous and one CC-induced.
Main Results:
- Endometrial LIF levels were comparable in spontaneous (470 +/- 52 pg/g) and CC-induced (501 +/- 45 pg/g) cycles.
- No statistically significant difference was observed in LIF levels between the two cycle types.
- Ovulation induction with CC did not negatively impact endometrial LIF concentrations.
Conclusions:
- Clomiphene citrate (CC) administration does not adversely affect endometrial leukemia inhibitory factor (LIF) levels.
- This suggests CC-induced cycles maintain endometrial receptivity comparable to natural cycles for patients with unexplained infertility.
