Premature ovarian insufficiency and perinatal parameters: A retrospective case-control study

Area of Science:

• Reproductive Endocrinology
• Women's Health
• Perinatal Medicine

Background:

• Premature ovarian insufficiency (POI) affects 1% of women, characterized by early follicle depletion before age 40.
• Oocyte numbers peak during development and decline thereafter, leading to menopause.
• The perinatal environment's influence on POI development is not fully understood.

Purpose of the Study:

• To investigate the association between perinatal factors (birth weight and prematurity) and POI.
• To determine if women with POI experienced different birth outcomes compared to controls.

Main Methods:

• A retrospective case-control study comparing 59 women with POI to 92 controls (natural menopause >40 years).
• Analysis of birth weight and prematurity rates (<37 weeks gestation).
• Binary logistic regression adjusted for smoking.

Main Results:

• Women with POI had a significantly higher rate of prematurity (13.6%) compared to controls (6.6%, p=0.018).
• No significant difference in birth weight was observed between the groups after correcting for gestational age.
• Key demographic and lifestyle factors were similar between groups.

Conclusions:

• Prematurity is identified as a risk factor for developing POI.
• Prenatal or postnatal factors associated with prematurity may contribute to early follicle depletion.
• Further research into prematurity's impact on ovarian reserve is warranted.
