ABSTRACT
Studies demonstrated that deficiency in 17ß-estradiol (E2) in postmenopausal women influences their immune system. However, few studies have reported alterations in immunologic presentation during nonnatural menopause in young females. Here we compared the differences in immune response between young C57BL/6N mice with surgical or medical variectomy and aged C57BL/6N mice with the common feature of E2 deficiency following Con A stimulation. We observed inverted CD4/CD8 ratios in the aged group and apparent reduced production of serum immunoglobin (Ig)G, IgA, and IgM in the surgical group, whereas changes in immune parameters in the medical group were moderate. These data suggested that the immunological response to Con A stimulus differed among the three groups and that E2 deficiency was only partially responsible for the development of immune deficiency in aged mice.

PURPOSE: To evaluate the ovarian reserve after laparoscopic cystectomy with suturing in patients with endometriomas. METHODS: A total of 80 women with unilateral or bilateral endometriomas underwent laparoscopic cystectomy using sutures for hemostasis after the excision of ovarian cysts. Serum levels of antimullerian hormone (AMH) and FSH were measured at the day 3 of menstrual cycles preoperatively, 6 and 12 months postoperatively. RESULTS: In the bilateral endometrioma group, serum AMH level decreased significantly from the baseline (4.68 ± 2.87 ng/ml) to 6 months (3.05 ± 1.99 ng/ml) and 12 months (2.26 ± 1.88 ng/ml) postoperatively, whereas the FSH level increased significantly from baseline to 12 months postoperatively (P < 0.05). Those patients with unilateral endometriomas also had lower levels of AMH in 6 and 12 months after operation. When compared between unilateral and bilateral endometrioma group, the rate of AMH decline 6 and 12 months and the rate of FSH increase 12 months postoperatively reached statistical significance (P < 0.05). CONCLUSIONS: The changes of the AMH and FSH values suggest that the ovarian reserve is obviously reduced in spite of suturing technology used as a method of hemostasis after stripping ovarian endometriomas, especially in those with bilateral cysts. The protective effect of the ovarian suturing for ovarian reserve may be marginal.
