目的 探讨多囊卵巢综合征(PCOS)患者药物诱导排卵治疗中发生未破裂黄素化卵泡综合征(LUFS)的相关因素。方法 对比克罗米酚(CC)及人绝经后促性腺激素(HMG)方案用药前后PCOS患者血清PRL、FSH、LH、E_2、T水平,阴道超声检查卵巢形态,分析PCOS患者LUFS发生与基础性激素水平和卵巢形态的关系。结果 应用CC加用HCG45例,卵泡发育率66.67％,周期妊娠率为22.22％,LUFS发生率33.33％;应用CC无效者,应用HMG方案30例,卵泡发育率高(86.67％),但LUFS和过度刺激综合征(OHSS)发生率高分别为36.67％和13.33％,周期妊娠率16.67％。T水平LUFS组高于排卵组,表明LUFS的发生与血清睾酮水平有关。周边囊泡型多囊卵巢(PCP)LUFS发生率25％,普通囊泡型多囊卵巢(GCP)LUPS发生率75％。结论 普通囊泡型多囊卵巢患者易于发生卵泡黄素化不破裂综合征,可能与患者雄激素水平相对较高,卵巢包膜厚,优势卵泡不是发生在卵巢周边有关。     

Aromatase inhibition reduces the dose of gonadotropin required for controlled ovarian hyperstimulation

OBJECTIVE: To compare the use of the aromatase inhibitor, letrozole, in conjunction with follicle-stimulating hormone (FSH) injection, and FSH alone for controlled ovarian hyperstimulation (COH) in patients with polycystic ovarian syndrome (PCOS) or ovulatory infertility. METHODS: This nonrandomized study included two study groups: 26 patients with PCOS and 63 with ovulatory infertility (unexplained infertility [41 patients], male factor infertility [17 patients], and endometriosis [5 patients]), who received letrozole in addition to FSH; and two control groups: 46 PCOS patients and 308 with ovulatory infertility (unexplained infertility [250 patients], male factor infertility [42 patients], and endometriosis [16 patients], who received FSH only. All patients had intrauterine insemination (IUI). Main outcome measures included dose of FSH used per cycle, number of preovulatory follicles greater than 16 mm in diameter, cancellation rate, and pregnancy rate. RESULTS: The FSH dose required for ovarian stimulation was significantly lower when letrozole was used in both study groups compared to the control groups without a significant difference in number of follicles greater than 16 mm. IUI cancellation rate was significantly lower with letrozole treatment in PCOS patients. In women with PCOS, clinical pregnancy rate per completed IUI cycle was 26.5% in the letrozole plus FSH group versus 18.5% in the FSH-only group. In ovulatory infertility patients, the pregnancy rate was similar in both study and control groups (11%). CONCLUSION: We believe that inhibition of estrogen synthesis by aromatase inhibition will release the estrogenic negative feedback, resulting in an increase in endogenous FSH secretion. Moreover, by inhibiting conversion of androgens into estrogens, accumulating androgens may increase follicular sensitivity to FSH. Such a protocol has the potential to lower FSH treatment cost and may improve response for low responders who require high FSH doses during ovarian stimulation.     

A case of polycystic ovary syndrome conceived by intracytoplasmic sperm injection following laparoscopic ovarian drilling

Polycystic ovary syndrome (PCOS) is a disease in which an ovulation disorder is the main cause of infertility. Clomifene citrate (CC) is the treatment of first choice for ovulation induction in PCOS. If ovulation cannot be induced by CC, then either laparoscopic ovarian drilling (LOD) or gonadotropin therapy is selected as a subsequent treatment. Assisted reproductive technology (ART) is indicated for women with PCOS, similar to other infertility patients, when pregnancy is not achieved by intrauterine insemination (IUI). In this study, we experienced a case of PCOS in which pregnancy was achieved by ART following LOD. The case pertains to a 26-year-old patient. She consulted our hospital with a chief complaint of primary infertility. IUI with administration of CC plus recombinant follicle-stimulating hormone (rFSH) was carried out; however, pregnancy was not achieved. Subsequently, ART was carried out. In the first attempt, the development of several follicles was observed under the gonadotropin releasing hormone (GnRH) agonist long protocol. However, a fertilized oocyte was not obtained. In the second attempt, an ovum could not be collected after CC-rFSH ovarian stimulation. In the third attempt, a good quality embryo could not be obtained under the GnRH antagonist protocol, and therefore pregnancy could not be achieved. We performed LOD using a harmonic scalpel for the purpose of preventing severe OHSS and improving the quality of embryos. Following the operation, ovarian stimulation was performed under the CC-rFSH-antagonist protocol. Eighteen follicles were aspirated, six oocytes were picked-up, and five oocytes were normally fertilized. As a result, four embryos from day 2 culture were cryopreserved. Cryopreserved-thawed embryo transfer was thereafter performed, and a single pregnancy was achieved. LOD is a clinically effective treatment for PCOS requiring ART.     

In-vitro maturation versus IVF with GnRH antagonist for women with polycystic ovary syndrome: treatment outcome and rates of ovarian hyperstimulation syndrome

In-vitro maturation (IVM) treatment has gained popularity for decreasing the incidence of ovarian hyperstimulation syndrome (OHSS) by eliminating or minimizing the use of gonadotrophins in women with polycystic ovary syndrome (PCOS). Studies have shown that IVF with GnRH-antagonist protocol is associated with a lower incidence of OHSS. Data comparing the relative success of these two treatments is, however, lacking. Treatment outcome and rates of OHSS were compared in patients with PCOS who underwent assisted conception with either IVM or IVF with GnRH-antagonist protocol between 2006 and 2011. The number of oocytes retrieved was higher in the IVM group, whereas the number of mature oocytes, fertilization rate and number of embryos cleaved were comparable. The implantation rate was higher in the IVF group. The clinical pregnancy rates per embryo transfer were not statistically different (IVF: 45.8% versus IVM: 32.4%). The live-birth rate was higher in the IVF group (IVF: 40.7% versus IVM: 23.5%; P = 0.04). Five women developed moderate or severe OHSS in the IVF group, whereas none did in the IVM group. Both IVM and IVF with GnRH-antagonist protocol seem to be effective treatment regimens in women with PCOS, although IVM is associated with a lower risk of OHSS.

Modern trends in ovulation induction

Patients with anovulatory infertility, who received treatment at one unit over a four year period, were assessed to determine the pregnancy rate and the incidence of complications while undergoing ovulation induction with gonadotropins. The patients in this group who had further in vitro fertilization (IVF) treatment were followed up, and the outcome in IVF cycles was assessed. Data from a total of 75 patients, who had completed 91 episodes of treatment involving 273 cycles of ovulation induction over a 4-year period in a University-affiliated teaching hospital, was analysed retrospectively. The cumulative pregnancy rate was 34% after three ovulation induction cycles, and was 46% overall. The clinical pregnancy rate per cycle was 15.4%, and per ovulatory cycle was 21%. The multiple pregnancy rate was 12%, and there were no cases of ovarian hyperstimulation syndrome (OHSS). In this group of patients undergoing ovulation induction, the multiple pregnancy rate was 12% and there were no cases of ovarian hyperstimulation syndrome (OHSS). The multiple pregnancy rate was 17%. Our result indicate that anovulatory patients benefit from ovulation induction with gonadotropins prior to IVF treatment.
