OBJECTIVETo investigate the clinical efficacy of levonorgestrel-releasing intrauterine system (LNG-IUS) in the treatment of adenomyosis.

METHODSSeventy patients with adenomyosis diagnosed according to clinical symptoms, magnetic resonance imaging (MRI) findings, laparoscopy and/or color-Doppler ultrasound imaging were treated with LNG-IUS, and the menstrual blood volume, dysmenorrhea, uterine volume, hepatic function and serum lipids were observed and evaluated.

RESULTSIn the first month of treatment, the menstrual blood size was reduced significantly to (35-/+12)% of that before treatment (P<0.01), and further to (7-/+4)% in the twelfth month (P<0.01). The average uterine volume was decreased by 18.6% (P<0.05) after the treatment, and dysmenorrhea was obviously relieved or completely disappeared alleviated. The condition of anemia was also improved rapidly, and no obvious side-effects on hepatic function and serum lipids were observed.

CONCLUSIONLNG-IUS is an effective and safe therapy for adenomyosis.

BACKGROUND: There is a dearth of studies that explore the perceptions of male partners of adolescent females towards the intention of pursuing contraception.

OBJECTIVE: To determine the role of male partner perceptions in the intention to use of contraception among female adolescents to prevent unplanned repeat pregnancies.

MATERIALS AND METHODS: An urban sample of 102 male partners of female adolescents with previous pregnancy experience coming from the out-patient department and selected barangay health center responded to a two-part questionnaire that explored their perceptions towards contraception. Demographic data and their positive and negative views, attitudes and actual practice of contraception as it affects future intention to engage in family planning methods were determined.

RESULTS: Male sexual partners have positive perceptions towards contraception. Despite this, utilization rate was still low (56.8%). Positively correlated with contraceptive intention include the male partner's advanced age and high level of education. Perceptions that favor strong intention include careful pregnancy planning in the future, not wanting a pregnancy too soon, knowledge of a specific method, its perceived benefits, "shared decision" making, feeling "happy" when contraceptives are offered rather than forced and when a woman lacks trust in him. Forcing contraception by the female adolescent partner was negatively correlated with contraceptive intention.

CONCLUSION: Shared decision making towards contraception in order to reduce unintended pregnancies should engage the male partner's participation by correcting prevailing misperceptions.

Objective: To evaluate different methods' efficacy of controlling acute bleeding and managing long-term menstruation in patients with heavy menstrual bleeding (HMB) associated with antithrombotic therapy. Methods: The clinical data of 22 cases with HMB associated with antithrombotic therapy admitted to Peking University People's Hospital from January 2010 to August 2022 were analyzed, aged 39 years old (26-46 years). Changes in menstrual volume, hemoglobin (Hb), and quality of life were collected after control of acute bleeding and long-term menstrual management. Menstrual volume was assessed by pictorial blood assessment chart (PBAC), and quality of life was assessed by menorrhagia multi-attribute scale (MMAS). Results: (1) Treatment of acute bleeding: of the 22 cases with HMB associated with antithrombotic therapy, 16 cases were treated in our hospital and 6 in other hospital for emergency bleeding; of the 16 cases treated in our hospital, 3 underwent emergency intrauterine Foley catheter balloon compression due to severe bleeding (Hb decreased by 20 to 40 g/L within 12 hours). Of the 22 cases with antithrombotic therapy-related HMB, 15 (including 2 cases with severe bleeding) underwent emergency aspiration or endometrial resection, and intraoperative placement of levonorgestrel-releasing intrauterine system (LNG-IUS) followed by a significant reduction in bleeding volume; 3 cases had controlled acute bleeding after rivaroxaban dose reduction and continued observation; 2 cases were given gonadotropin-releasing hormone agonists to control acute bleeding in other hospital, of which 1 case was temporarily treated with periodic blood transfusion, and the other one patient underwent total hysterectomy; and 2 cases had temporary amenorrhea with oral mifepristone after intrauterine balloon compression or oral norethindrone. (2) Long-term menstrual management: of the 22 cases with antithrombotic therapy-related HMB, 15 had LNG-IUS placement and 12 had LNG-IUS placement for 6 months, and menstrual volume was significantly reduced [PBAC scores were 365.0 (272.5-460.0) vs 25.0 (12.5-37.5), respectively; Z=4.593, P<0.001], Hb was significantly increased [91.5 g/L (71.8-108.2 g/L) vs 128.5 g/L (121.2-142.5 g/L); Z=4.695, P<0.001], and quality of life was significantly improved [MMAS scores were 415.0 (327.5-472.5) vs 580.0 (570.0-580.0), respectively; Z=-3.062, P=0.002] before placement compared with 6 months after placement. Three rivaroxaban dose reduction patients' PBAC scores decreased by 20 to 35 but remained >100, and perceived quality of life did not change significantly. Two cases with temporary amenorrhea treated with oral mifepristone felt significantly improved quality of life, and the MMAS scores increased by 220 and 180, respectively. Conclusion: Intrauterine Foley catheter balloon compression, aspiration or endometrial ablation could be used to control acute bleeding in patients with antithrombotic therapy-related HMB, and LNG-IUS for long-term management could reduce menstrual volume, increase hemoglobin, and improve the quality of life of patients.

The intrauterine device (IUD) is gaining popularity as a reversible form of contraception. Ultrasonography serves as first-line imaging for the evaluation of IUD position in patients with pelvic pain, abnormal bleeding, or absent retrieval strings. This review highlights the imaging of both properly positioned and malpositioned IUDs. The problems associated with malpositioned IUDs include expulsion, displacement, embedment, and perforation. Management considerations depend on the severity of the malposition and the presence or absence of symptoms. Three-dimensional ultrasonography has proven to be more sensitive in the evaluation of more subtle findings of malposition, particularly side-arm embedment. Familiarity with the ultrasonographic features of properly positioned and malpositioned IUDs is essential.

Recently, research on male reproductive ability brings along the concern on male reproductive health. At present time, the situation of reproductive health was not optimistic and many problems need to be solved. In this article, many important topics were included, such as the changing and the possible reasons of male reproductive health; much concern was needed for babies, children, and male juvenile; increasing tendency of the infection rates of male urogenital system; research on male infertility needed to be explored deeply; there was no satisfactory methods for male contraception; the diagnosis and treatment of male erectile dysfunction were not sufficient for the need; research on andropause was at the primary stage; life regime of men needed to be adjusted. Concerning for male reproductive health is the responsibility of both medical workers and whole society.

We describe the successful removal of a pelvic contraceptive coil in a symptomatic 46-year-old patient who had Essure devices for four years, using a combined hysteroscopy-laparoscopy-fluoroscopy approach. Following normal hysteroscopy, at laparoscopy the right Essure implant was disrupted and its outer nitinol coil had perforated the fallopian tube. However, the inner rod (containing polyethylene terephthalate) had migrated to an extrapelvic location, near the proximal colon. In contrast, the left implant was situated within the corresponding tube. Intraoperative fluoroscopy was used to confirm complete removal of the device, which was further verified by postoperative computed tomography. The patient's condition improved after surgery and she continues to do well. This is the first report to describe this technique in managing Essure complications remote from time of insertion. Our case highlights the value and limitations of preoperative and intraoperative imaging to map Essure fragment location before surgery.

This study taking gestodene (GEST) as a model, investigated the factors affecting reservoir-type intravaginal ring (IVR)'s drug release. This paper reported a gestodene intravaginal ring of reservoir design, comprising a gestodene silicone elastomer core encased in a non-medicated silicone sheath, separately manufactured by reaction injection moulding at 80 degrees C and heating vulcanization at 130 degrees C is reported. The test investigated the factors affecting drug release through a single variable method, taking the drug release rates of 21 days as standards. When changing the thickness of the controlling sheath outside, the ratio of the first day of drug release and mean daily release (MDR), named the relatively burst effect, is closing to 1 with the thickness of controlling sheath increasing, while the 1.25 mm sheath corresponding to 1.04 controlled the burst release effectively; a positive correlation (r = 0.992 2) existed between the average drug release (Q/t) and drug loading (A) within a certain range. The C6-165 controlling sheath with high solubility of GEST is easier to achieve controlled release of the drug; GEST crystalline power is more effective to implement controlled release of drugs among difficent states of the drug. A 1/4 fractional segment core gives a relatively burst effect of 1.76, while the 1/1 and 1/2 are 1.93 and 1.87 separately, at the same drug loading, concluding that use of a fractional segment core would allow development of a suitable GEST reservoir IVR. In summary, GEST reservoir-type IVR could be adjusted by the thickness of controlling sheath, the loading of drug, the material properties of controlling sheath, the dispersion state of drug, the additive composition and structure of intravaginal ring, to control the drug release behavior and achieve the desired drug release rate.
