Ovarian pregnancy is comparatively rare form of ectopic pregnancy. Although earlier diagnosis is now possible due to the availability of quantitative beta-hCG measurement and the development of transvaginal ultrasonograghy, it is mostly difficult to diagnosis before surgery, and frequently misdiagnosed as a ruptured corpus luteum accompanied with massive hemoperitoneum. Definite diagnosis is made only by cytopathologic examination of tissue specimen. The treatment of ovarian pregnancy has been operative management including oophorectomy, salpingo-oophorectomy and ovarian wedge resection. But recently conservative management using laparoscopic technique has become the preferred treatment. We have experienced a case of primary ovarian pregnancy and reviewed it briefly.

Primary ovarian pregnancy is a rare form of ectopic pregnancy, and the prevalence rate is reported to be between 1/7,000 and 1/40,000 pregnancies. Ovarian pegnancy occurs within the ovary and on the corpus luteum, usually with rupture and massive bleeding. It is frequently misdiagnosed as a ruptured corpus luteum and the differentiation may be made only by micoroscopic examination of a tissue specimen. We have experienced four cases of ovarian pegnancy, which are presented with a brief review in the literature.

Ovarian pregnancy is a rare form of ectopic pregnancy that is often difficult to diagnose. The diagnostic criteria were described in 1878 by Spiegelberg, which comprise that the pregnancy is in the ovary and does not involve the tube. Ovarian pregnancy occurs in the corpus luteum, and is usually accompanied with the rupture of the ovary and massive hemoperitoneum. It presents as a hemorrhagic ovary and frequently misdiagnosed as a ruptured corpus luteum. We have experienced a case of ovarian pregnancy and reviewed it briefly.

OBJECTIVE: To understand the physiologic effects and secretion pattern of inhibin A and inhibin B during menstrual cycle and menopausal transition, inhibin A and inhibin B levels were measured. And to detect any changes in expression of inhibins in human ovary with age, we examined immunohistochemical staining of alpha, beta A, and beta B subunits of inhibin in ovarian tissues. This study was also designed to investigate whether or not inhibin is an early marker for menopausal transition. METHODS: Inhibin A and inhibin B levels were measured in 320 samples from normal reproductive women, in 60 from perimenopausal women, and in 20 from menopausal women by ELISA. And we examined the immunohistochemical staining of alpha, beta A, and beta B subunits of inhibin in ovarian tissues of 35 normal reproductive, 20 perimenopausal, and 5 menopausal women, respectively. RESULTS: In the normal reproductive women, inhibin A begins to increase in the late proliferative phase (16.53 +/- 1.57 pg/ml), reaches the peak in the mid-secretory phase (45.85 +/- 2.08 pg/ml), and subsequently decreases. Inhibin B begins to increase in the early proliferative phase (65.40 +/- 4.08 pg/ml), reaches the peak in the ovulatory phase (110.74 +/- 9.83 pg/ml), and thereafter declines rapidly. In the perimenopausal women, mean inhibin A serum concentration was 6.68 +/- 0.53 pg/ml during proliferative phase and 21.78 +/- 3.61 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01). Mean inhibin B serum concentration was 52.16 +/- 7.46 pg/ml during proliferative phase and 22.41 +/- 6.73 pg/ml during secretory phase, which were significantly lower than that of the same phase in the normal reproductive women (P<0.01, P=0.025). In the menopausal women, both inhibin A and inhibin B were not detected. In the normal reproductive women, we observed strong immunostaining for alpha subunit in granulosa cells, theca cells, and corpus luteum. Immunostaining for beta A subunit was observed in corpus luteum, but not in growing follicles. Immunostaining for beta B subunit was observed in primary follicle, granulosa and theca cells of growing follicle, and mature follicle, but less strong than immunostaining for alpha subunit. No staining for beta B subunit was observed in the corpus luteum. In the perimenopausal women, immunostaining for inhibin subunits were observed in the same pattern as that of the normal reproductive women, but weaker. Stronger immunostaining was observed in theca cells than in granulosa cells. In the menopausal women, none of the immunostaining of inhibin subunits were observed. CONCLUSION: It is concluded that inhibin A is associated with the luteal function and inhibin B, the follicular function. The secretion of inhibins decreased rapidly in the perimenopausal transition period and were not detected in the menopausal period. Inhibin A and inhibin B are associated with the follicular maturation and development. It suggests that the inhibin A and inhibin B are good candidates as markers for perimenopausal transition.

OBJECTIVES: The purpose of this study is to investigate the expression of CDK (Cyclin dependent kinase) inhibitor, p57(kip2) in human ovarian corpus luteum, benign and malignant ovarian tumors. METHODS: 46 women undergoing laparoscopic surgery or laparotomy for ovarian tumors were enrolled. Total 46 formalin-fixed, paraffin-embedded sections of corpus luteum, benign and malignant ovarian tumors were stained by immunohistochemistry for expression of p57(kip2). RESULTS: p57(kip2) was stained in theca cell of growing follicle but not induced in human corpus luteum. There was the expression of p57(kip2) in mature teratoma, immature teratoma and endometrioma but not in epithelial ovarian tumors. CONCLUSIONS: These results showed that p57(kip2) expression may be not important in luteinization of the ovary and seemed not to play a role in development of epithelial ovarian tumors. However, it may involve pathogenesis of mature teratoma, immature teratoma and endometrioma.

Primary ovarian ectopic pregnancy has remained a rare event. It is difficult preoperatively to diagnose and differentiate ovarian pregnancy from hemorrhagic ovarian cyst and tubal ectopic pregnancy. However, improved diagnosis of acute hemoperitoneum of ovarian origin may reveal a higher incidence than reported earlier. The diagnostic criteria were described in 1878 by Spiegelberg, which comprise that the pregnancy is in the ovary and does not involve the tube. Ovarian pregnancy occurs within the ovary and on the corpus luteum, usually with rupture of the ovary and a massive hemoperitoneum. We report a relatively intact primary ovarian pregnancy with a brief review of the literatures.

OBJECTIVE: To identified whether serum Mullerian inhibiting substance (MIS) level may be used as a predictive marker of menopausal transition. METHODS: Serum MIS level was measured in reproductive women (n=87), in menopausal transition women (n=58), and in menopausal women (n=5) by ELISA. And we examined the immunohistochemical staining of the MIS in the ovarian tissues of 15 reproductive, 15 menopausal transition, and 5 menopausal women. RESULTS: 1. In the reproductive women, mean serum MIS level was 1.73+/-1.07 ng/ml. In the menopausal transition women, mean serum MIS level was 0.18+/-0.11 ng/ml. Serum MIS level did not show any significant fluctuation patterns according to follicular development. In menopausal transition women, serum MIS level was significantly lower than that of reproductive women (P<0.001). The cutoff value of serum MIS level for menopausal transition was 0.5 ng/mg. In the menopausal women, serum MIS level was not detected. 2. Serum MIS level was significantly decreased as patient age was increased. 3. In the reproductive group, the immunohistochemical staining demonstrated strong expression of MIS in the granulosa cells of the primary follicles and the growing follicles, but not in corpus luteum, preovulatory mature follicle, atretic follicle, and corpus luteum. In the menopausal transition women, immunohistochemical staining for MIS was observed in the nearly same pattern as that of thereproductive women, but with weaker expression. In the menopausal women, immunohistochemical staining of the MIS was not observed. CONCLUSION: MIS is a good candidate for predictive marker for ovarian aging and perimenopausal transition.

Ovarian Pregnacy is a rare form of ectopic pregnacy. Its estimated overall incidence is highly variable, but improved diagnosis of acute hemoperitoneum of ovarian pregnancy may reveal a high incidence than reported earlier. Ovarian pregnancy occurs in the corpus luteum, and is usually accompanied with the rupture of the ovary and massive hemoperitoneum. It presents as a hemorragic ovary and frequently misdiagnosed as a ruptured corpus luteum. Risk facters to ovarian pregnacy include a history of pelvic inflammatory disease(PID), prior pelvic surgery, and use of an intrauterine contraceptive device(IUD). We have experienced two cases of ovarian pregnancy and reviewed it briefly.

OBJECTIVE: The purpose of this study was to evaluate the endocrine response to step-up microdose GnRH agonist. METHODS: Administration of triptorelin acetate was initiated from 2 mg and gradually increased to 50 mg during 6-day period to five normal menstruating women. Serum FSH, LH, and estradiol levels were serially measured for 6 days. The same set of experiment was duplicated after taking oral contraceptive for 3 weeks. Serum testosterone and progesterone levels were measured on day 1 and day 5 of experiment. RESULTS: The flare of gonadotropin continued for 6 days. When subjects were pretreated with oral contraceptive, serum FSH levels 4 hrs after GnRH agonist injection were 17.35+/-7.88 mIU/mL, 11.26+/-4.81 mIU/mL, and 9.60+/-4.08 mIU/mL for day 1, 2, and 3 respectively. The FSH levels were not statistically different when pretreatment with oral contraceptive was not applied. The level of serum LH was significantly lower in the cycle, which was pretreated by oral contraceptive (32.13+/-9.61 mIU/mL vs. 14.12+/-5.63 mIU/mL for day 1, 28.95+/-3.09 mIU/mL vs. 15.76+/-9.92 mIU/mL for day 2, and 24.45+/-2.52 mIU/mL vs. 16.86+/-8.56 mIU/mL for day 3). The sign of corpus luteum rescue was found in 2 out of 5 subjects only in non-treated cycle. CONCLUSION: Step-up microdose GnRH agonist protocol could induce persistent gonadotropin flare for 6 days and this regimen could be applied in controlled ovarian hyperstimulation especially for poor responders. The pretreatment with oral contraceptive is necessary to prevent supraphysiologic LH elevation and corpus luteum rescue.

OBJECTIVE: To investigate the histologic features of the uterus and adnexae extirpated from gender identity disorder (GID) patients that received depot androgen injection. METHODS: We reviewed the histologic findings of the uterus and adnexae removed from sixteen GID patients, who had taken depot androgen injection for 5~168 months. RESULTS: Fourteen patients (87.5%) showed the atrophied epithelium of exocervix and all of 16 patients (100%) showed the atrophy of endometrium. Seven patients (43.7%) showed multiple cystic follicles in the ovarian cortex and 6 patients (37.5%), 3 patients (18.7%) showed corpus albicans and corpus luteum, respectively. CONCLUSIONS: Exogenous androgen induced atrophy of cervix and endometrium. This effect was more prominent in the endometrium. In addition, PCO-like histologic features were observed in the ovary.
