Ovarian response in three consecutive in vitro fertilization cycles

Area of Science:

• Reproductive Endocrinology
• In Vitro Fertilization (IVF)

Background:

• Assessing patient variability in ovarian response is crucial for optimizing IVF success rates.
• Understanding the consistency of ovarian response within the same patient across multiple cycles is key for personalized fertility treatment.

Purpose of the Study:

• To evaluate the consistency of ovarian response in women undergoing consecutive in vitro fertilization (IVF) cycles.
• To determine if the number of follicles and oocytes retrieved remains stable across three sequential IVF attempts within the same patient.

Main Methods:

• Retrospective analysis of 190 women undergoing three consecutive IVF cycles at a university hospital's assisted reproductive unit.
• Standard pituitary desensitization and gonadotropin stimulation protocols were used for all participants.
• Ovarian response was quantified by the number of follicles produced and oocytes retrieved.

Main Results:

• No statistically significant differences were observed in the number of follicles produced across the three consecutive IVF cycles for individual patients.
• The number of oocytes retrieved showed no significant variation between the first, second, and third IVF cycles within the same patient.
• Embryo creation rates also remained consistent among the three consecutive treatment cycles.

Conclusions:

• The study demonstrates a consistent ovarian response in women during their first three consecutive IVF cycles.
• This finding suggests predictability in ovarian response, which can inform treatment strategies and patient counseling in assisted reproduction.
