Endometrial evaluation is not predictive for in vitro fertilization treatment

Area of Science:

• Reproductive Endocrinology
• Infertility Research
• Assisted Reproductive Technologies

Background:

• Tubal infertility affects a significant number of women seeking fertility treatments.
• Clomiphene citrate (CC) is commonly used to stimulate ovulation.
• Evaluating ovarian reserve and endometrial receptivity is crucial for successful in vitro fertilization (IVF).

Purpose of the Study:

• To assess ovarian function using the clomiphene citrate (CC) challenge test in women with tubal infertility.
• To investigate endometrial morphological maturation during CC-stimulated cycles.
• To correlate these findings with in vitro fertilization (IVF) treatment outcomes.

Main Methods:

• The clomiphene citrate (CC) challenge test was administered to women with tubal infertility.
• Endometrial morphology was evaluated in the early luteal phase of CC-stimulated cycles.
• Hormonal levels (follicle-stimulating hormone, estradiol, progesterone) and endometrial characteristics were analyzed.
• Outcomes were compared between pregnant and non-pregnant groups following IVF.

Main Results:

• Four women exhibited retarded endometrial development; three had impaired ovarian function with elevated follicle-stimulating hormone.
• No significant differences in endometrial morphology or thickness were observed between pregnant and non-pregnant groups.
• Significant differences in luteal phase estradiol and progesterone levels were found between those who conceived and those who did not.

Conclusions:

• Luteal phase endometrial morphology is not a precise indicator for predicting pregnancy following IVF.
• Ovarian function, evaluated through hormonal markers, appears to be a more dependable prognostic factor for IVF success in this cohort.
