Objectives: To evaluate changes of ovarian reserve after hysterectomy by comparing serum anti-Mullerian hormone (AMH) levels following laparoscopic hysterectomy (LH) to those of non-laparoscopic hysterectomy (non-LH).
Methods: Prospectively, serum AMH levels were measured pre-operatively (AMH0), 7days (AMH1), 2 months (AMH2), and 6 months (AMH3) after LH (total laparoscopic hysterectomy or laparoscopy-assisted vaginal hysterectomy) and non-LH (vaginal hysterectomy or abdominal hysterectomy) in 91 premenopausal women (LH=60, non-LH=31). Changes of serum AMH levels were compared between the two groups.
Results: AMH0 was similar between the two groups (P=0.400). Also, AMH1, AMH2, and AMH3 were not different between the two groups (P=0.333, 0.534, and 0.726). A significant decrease of serum AMH level (30% decreases from AMH0) at 7days, 2 months, and 6 months was observed in 44.4%, 34.8%, and 40% of all patients. Interestingly, the incidence of a significant decrease of serum AMH levels at postoperative 2 months was considerably higher in LH group compare to non-LH group (43.9% vs. 20.0%, P=0.042). Multivariate analysis revealed that laparoscopic hysterectomy was an independent risk factor for the significant decrease of serum AMH at postoperative 2 months (Hazard ratio 4.147, 95% confidence interval 1.139-15.097).
Conclusion: Laparoscopic hysterectomy, which is associated with electro-thermal vessel ligation, might have negative effect on ovarian reserve after surgery. More large-scaled, long-term follow-up study is required.

Background: Differential diagnosis of hypogonadotropic hypogonadism (HH) and constitutional delay of puberty (CDP) is extremely important since with the latter puberty begins and completes without any medical intervention and in the case of HH puberty does not occur or is incomplete. Failure to start treatment on time leads to medical and psychosocial maladjustment of the patient.
Aim: Development of a method for differential diagnosis of hypogonadotropic hypogonadism and constitutional delay of puberty in boys 13.

Objective: Polycystic ovary syndrome (PCOS) is a diverse condition with an unknown cause. The precise mechanism underlying ovulatory abnormalities in PCOS remains unclear. It is widely believed that malfunction of granulosa cells is the primary factor contributing to aberrant follicular formation in PCOS.

Radiotherapy is a critical treatment for cancer but poses significant risks to ovarian tissue, particularly in young females, leading to premature ovarian failure (POF). This study examines the therapeutic potential of etoricoxib nanostructured lipid carriers (ETO-NLC) in mitigating radiation-induced ovarian damage in female rats. Twenty-four female rats were randomly assigned to four groups: a control group receiving normal saline, a group exposed to a single dose of whole-body gamma radiation (6 Gy), a group treated with etoricoxib (10 mg/kg) post-radiation, and a group treated with ETO-NLC for 14 days following radiation.

Background: Proper planning of reproductive health needs for HIV-infected adolescents requires a clear understanding of the effects of HIV infection on adolescents' pubertal development.
Objective: To assess the effects of HIV infection on the hypothalamic-pituitary-ovarian (HPO) axis, ovarian reserve and pubertal development in adolescent girls at a tertiary hospital in Zimbabwe.
Methods: This was a cross-sectional survey of HIV-infected adolescent girls aged 10-19 years, with available CD4 + count results at a tertiary hospital in Zimbabwe.
The impact of hysterectomy for benign uterine tumors on subsequent ovarian reserve, lower urinary tract symptoms, and sexual function: A prospective multidirectional short-term analysis.

Objective: To evaluate the effects of hysterectomy for benign uterine tumors on subsequent ovarian reserve, sexual function, and lower urinary tract symptoms (LUTS).
Methods: The present study was a prospective longitudinal analysis that recruited patients aged 35-45 years who underwent simple hysterectomy without oophorectomy for symptomatic benign uterine tumors. Anti-Müllerian hormone (AMH) and serum sex hormone profiles, including follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone, and total testosterone, were measured at four timepoints: before hysterectomy, and 3, 6, and 12 months postoperatively.
