Unilateral oophorectomy temporarily reduces ovarian reserve. Reproductive function recovers within a year for younger women, but not for those in late reproductive age, necessitating regular monitoring.
Area of Science:
- Reproductive endocrinology
- Gynecology
- Oncology
Background:
- Unilateral oophorectomy (UO) is a surgical procedure involving the removal of one ovary.
- Assessing the impact of UO on reproductive system function is crucial for patient management.
Purpose of the Study:
- To evaluate the functional status of the reproductive system after unilateral oophorectomy across different age groups.
- To determine the recovery of ovarian function and hormone levels post-surgery.
Main Methods:
- Forty-three patients aged 7–38 years underwent UO and were categorized into three age-based groups.
- Reproductive system function was assessed at 3 months and 1 year post-surgery, including Anti-Müllerian Hormone (AMH) levels.
Main Results:
- Post-UO, functional cysts developed in the remaining ovary in 69.8% of patients, more frequently in the oldest group.
- AMH levels significantly decreased 3 months after UO in all groups.
- AMH levels recovered within one year for patients aged 7–30 years but remained low for those aged 30–38 years.
Conclusions:
- UO causes a transient decrease in ovarian reserve across all ages.
- Functional ovarian activity is restored within one year for pubertal and early reproductive-aged women.
- Late reproductive-aged women do not show AMH recovery post-UO, and functional cysts are common, requiring regular follow-up.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...

Overview of the Reproductive System
The gonads, or primary reproductive organs, produce gametes and sex hormones. In males, the testes produce spermatozoa and testosterone, which is responsible for developing secondary male sex characteristics, including a deeper voice, larger muscles, facial and body...
Oogenesis
Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
