Do young women with unexplained infertility show manifestations of decreased ovarian reserve?

Clinical observation of Kuntai capsule combined with Fenmotong in treatment of decline of ovarian reserve function

BACKGROUND

Decreased ovarian reserve function is an ovarian hypofunction disease that occurs in women before 40 years of age, leading to a decline in fertility and perimenopausal symptoms, such as irregular menstruation, amenorrhea, infertility, decreased libido, and autonomic nervous dysfunction. Fenmatong (FMT) is a compound mixture of estradiol tablets and estradiol didroxyprogesterone tablets, which can improve ovarian reserve function by supplementation of exogenous estrogen. However, this treatment has also been shown to cause breast pain, gastrointestinal discomfort, irregular vaginal bleeding, and changes in sexual desire. In severe cases, FMT can promote the development of breast cancer, endometrial cancer, and venous embolic disease.

AIM

To observe the effects of Kuntai capsules and FMT on endocrine indexes and uterine artery blood circulation in patients with decreased ovarian reserve function.

METHODS

Patients (130) with decreased ovarian reserve function, who were treated in our hospital from May 2018 to May 2020, were divided into two groups: The FMT group, in which patients were treated with FMT, and the observation group, in which patients were treated with Kuntai capsules. Chinese medicine symptom scores, uterine artery blood flow parameters, ovarian ultrasound test indexes, pictorial blood loss assessment chart (PBAC) scores, and hormone levels were recorded, and total effective rates were calculated for both groups.

RESULTS

The total effective rate in the observation group was higher than that in the FMT group (P < 0.05).After treatment, primary symptoms, including low menstrual volume, delayed menstruation, red color and thick consistency of menses, dizziness, palpitation, weakness at the waist and knee, insomnia and excessive dreaming, irritability, and dryness and astringency of the pudendal canal in the observation group decreased, and scores for primary and secondary symptoms in the observation group were significantly lower than those in the FMT group (P < 0.05).The systolic peak flow rate (PSV), end-diastolic flow rate (EDV), ovarian diameter, sinus follicle count, and resistance index (RI) of the uterine arteries in the observation group and FMT group increased after treatment. Notably, the PSV, EDV, ovarian diameter, and antral follicle count in the observation group were higher than those in the FMT group, whereas the RI in the observation group was lower than that in the FMT group (P < 0.05).The PBAC scores in the observation and FMT groups increased after treatment, with that in the observation group becoming significantly higher than that in the FMT group (P < 0.05). After treatment, estradiol (E2) and anti-Mullerian hormone (AMH) levels increased, whereas follicle-stimulating hormone (FSH) levels decreased in the observation group and FMT group; E2 and AMH levels became significantly higher and FSH levels became significantly lower in the observation group than in the FMT group (P < 0.05).

CONCLUSION

Compared with FMT, Kuntai capsules promoted uterine artery blood circulation, improved menstruation, relieved symptoms, regulated endocrine function, and improved curative effects.

Anti-Müllerian hormone as a predictor of pregnancy in women under 35 years with unexplained infertility undergoing ICSI: a retrospective study

BACKGROUND

Anti-Müllerian hormone (AMH) is a well-established marker for the determination of ovarian reserve. However, its role in the prediction of pregnancy is still under debate. In this retrospective study, we aimed to evaluate the relationship of serum AMH levels with pregnancy rates in patients with unexplained infertility undergoing ICSI. Moreover, we compared the predictive value of AMH with that of antral follicle count (AFC).

METHODS

Records of 76 patients under 35 years of age with AMH levels between 1 and 3.5 ng/ml were examined retrospectively. Participants were divided into groups based on their AMH level and age.

RESULTS

AMH levels in women under 30 years were found significantly higher than those in women over 30 years (P=0.033). 57 of 76 patients (75%) were pregnant. Age did not have a significant effect on the pregnancy rates in the selected study group (P=0.252). On the other hand, despite the poor predictive accuracy, serum AMH was shown to have a predictive value with a cut-off point of 1.95 ng/mL. Logistic regression tests demonstrated a higher pregnancy rate (3.396 fold) with an AMH level 1.95 or above. There was no significant relationship between AFC and pregnancy.

CONCLUSIONS

AMH might have a role in the prediction of pregnancy after ICSI in patients under 35 years with unexplained infertility.

Effects of Bushen Huoxue method for female with decreased ovarian reserve: A protocol for systematic review and meta-analysis

BACKGROUND

Decreased ovarian reserve (DOR) is a common reproductive barrier in female. Bushen Huoxue (BSHX) method of TCM is widely applied to treat DOR clinically. The purpose of this study is to provide a systemic and comprehensive evaluation of BSHX in the treatment of DOR.

METHODS

We have registered this protocol with OSF registry and the DOI is 10.17605/OSF.IO/QNUE2. We will search 4 English databases (PubMed, EMBASE, MEDLINE, Cochrane Library) and four Chinese databases (China national knowledge infrastructure database, Wanfang database, VIP and Superstar database) from their inception to August 10, 2020. Two authors will search and extract independently all related studies. RevMan 5.3 software will be applied to synthesize data.

RESULTS

The results of this study will be published in a scientific journal after peer-review.

CONCLUSION

This systematic review will provide reliable evidences for clinicians, and help them make decisions in DOR management.

Special characteristics, reproductive, and clinical profile of women with unexplained infertility versus other causes of infertility: a comparative study

PURPOSE

To investigate whether women with unexplained infertility (UI) demonstrate different demographic and IVF characteristics compared to those with other causes of infertility.

METHODS

Data on 245 couples that underwent a total of 413 IVF/ICSI cycles were analyzed (UI 114 cycles, 73 women; anovulation (PCO/PCOS) 83 cycles, 51 women; tubal factor 85 cycles, 47 women; male factor 131 cycles, 74 women). Features of UI were compared versus other infertility groups, after adjustment for multiple comparisons. Generalized least squares (GLS) and random-effects logistic regression analysis were also performed.

RESULTS

Live birth rates, consisting of the primary outcome, were similar in all compared infertility groups. Compared to male infertility, UI was associated with woman's older age at cycle, lower body mass index (BMI), and higher follicle-stimulating hormone (FSH). Compared to tubal infertility, UI was linked to lower endometrial thickness at oocyte retrieval and lower BMI; compared to anovulatory infertility related to PCO/PCOS, UI was linked to woman's older age, more frequent smoking, and poorer ovarian reserve tests (FSH and antral follicle count). After adjustment for other types of infertility, woman's age, age at menarche, and FSH levels, anovulatory infertility presented with higher odds of clinical pregnancy compared to UI (adjusted OR = 2.13, 95% C: 1.01-4.52).

CONCLUSIONS

Infertile women with UI undergoing assisted reproduction demonstrate different demographic and clinical characteristics compared to those of other causes of infertility, albeit live birth rates are similar.

Ovarian cortical follicle density in infertile women with low anti-Müllerian hormone

PURPOSE

To evaluate the association between anti-Müllerian hormone (AMH) and follicle density in infertile women with diminished ovarian reserve (DOR) versus women with normal ovarian reserve?

METHODS

Case-control study comparing follicle densities in ovarian cortex from 20 infertile women with DOR (AMH ≤ 5 pmol/L) and 100 controls with presumed normal ovarian reserve.

RESULTS

For all women > 25 years, the follicle densities correlated positively with AMH levels. For each single picomole per liter increase in AMH the follicle density increased by 6% (95% CI 3.3-8.5%) when adjusted for age. This was similar for women with DOR and controls. The follicle density was 1.8 follicles/mm³ cortical tissue in women with DOR versus 7.0 in age-paired controls (p = 0.04). The women with DOR had a median AMH of 1.8 pmol/L versus 14.4 pmol/L in the age-paired control group (p < 0.001). The ratio of AMH/follicle density was 1:1 (1.8/1.8) in women with DOR and 2:1 (14.4/7.0) in the age-paired controls. Analyses for gonadotropin receptor polymorphisms could not explain the characteristics of women with DOR. The proportion of secondary follicles was higher in women with DOR compared with controls (4.6% versus 1.4%, p = 0.0003). Pooling all patients, the follicle density decreased significantly by 7.7% for every year added (p < 0.0001). The women with DOR had lower follicle densities than the controls, but the slopes were equal in the two cohorts.

CONCLUSIONS

Follicle density and AMH concentrations correlate also when AMH is low. However, AMH is only a reliable marker for the true ovarian reserve when age is included in the estimation and women with DOR may have more follicles than their AMH levels imply.
