Naturally occurring mutations in morphogenetic protein 15 (BMP15) are associated with decreased ovulation rate (OR), litter size (LS), and sterility. It is of a great interest to elucidate BMP15 gene in Cholistani sheep breed to uplift socio-economic status and the knowledge of Cholistani sheep breeding in Southern Punjab, Pakistan. In our study, a total of 50 infertile Cholistani sheep aged between 2-6 years and having no blood relation were screened for BMP15 mutations. For this purpose, a high-quality DNA was extracted from the blood of sheep followed by primer designing, Polymerase Chain Reaction (PCR) amplification, DNA sequencing, and in silico analyses. Out of total 50 samples, 9 samples including case 1 (T3), case 2 (T8), case 3 (T17), case 4 (T22), case 5 (T25), case 6 (T33), case 7 (T40), case 8 (T44), and case 9 (T47) were found positive for a variety of already reported and novel BMP15 mutations. Further in silico analyses of the observed mutations have shown the functional impact of these mutations on different characteristics (molecular weight, theoretical PI, estimated half-life, instability index, sub-cellular localization, and 3D confirmation) of the encoded proteins, possibly altering the normal functionality. In a nutshell, findings of this study have confirmed the possible essential role of the BMP15 mutations in the infertility of the Cholistani sheep.

Mutações de ocorrência natural na proteína morfogenética 15 (BMP15) estão associadas à diminuição da taxa de ovulação (TO), tamanho da ninhada (TN) e esterilidade. Estudar a BMP15 na raça Cholistani para elevar o status socioeconômico e o conhecimento da criação de ovinos Cholistani no sul de Punjab, Paquistão. Em nosso estudo, 50 ovelhas Cholistani inférteis sem parentesco sanguíneo foram rastreadas para mutações BMP15. Para tanto, um DNA de alta qualidade foi extraído do sangue dessas ovelhas, seguido de concepção do primer, amplificação da reação em cadeia da polimerase (PCR), sequenciamento de DNA e análises in silico. Do total de 50 amostras, 9, incluindo caso 1 (T3), caso 2 (T8), caso 3 (T17), caso 4 (T22), caso 5 (T25), caso 6 (T33), caso 7 (T40), caso 8 (T44) e caso 9 (T47), foram consideradas positivas para uma variedade de mutações BMP15 novas e já relatadas. Mais análises in silico das mutações observadas mostraram o impacto funcional dessas mutações em diferentes características (peso molecular, PI teórico, meia-vida estimada, índice de instabilidade, localização subcelular e confirmação 3D) das proteínas codificadas, possivelmente alterando a funcionalidade normal. Nossos achados confirmaram o possível papel essencial das mutações BMP15 na infertilidade de ovelhas Cholistani.

Infertile couples seeking treatment experience a social stigma that can lead to the need for privacy and, in turn, compromise their access to social support. This multiple case study, that involved the collection of sociodemographic and health data and interviews with four heterosexual couples accessed by convenience, aimed to examine the perception of the couples about the social support received after the disclosure of the condition of infertility and/or of the assisted reproductive technology treatment. The cases were analysed individually and comparatively. From the couples' statements, it is highlighted that all of them revealed something about infertility and/or treatment at some point in the process, although some considered not revealing it. Both support and lack of support were perceived from the revelations. The non-disclosure was motivated by self-preservation and by avoidance of social pressure. The findings indicate the importance of psychological intervention to expand the couples' social support.

Parejas infértiles que buscan tratamiento experimentan un estigma social que puede acarrear la necesidad de privacidad y, a su vez, comprometer el acceso al apoyo social. Ese estudio de múltiples casos, que involucró la recogida de datos sociodemográficos, de salud y entrevistas con cuatro parejas heterosexuales accedidas por conveniencia, buscó examinar la percepción de las parejas sobre el apoyo social después de la revelación de la condición de infertilidad y/o del tratamiento con técnicas de reproducción asistida. Los casos fueron analizados individual y comparativamente. De las declaraciones de las parejas, se destaca que todas revelaron algo sobre la infertilidad y/o el tratamiento en algún momento del proceso, aunque algunos consideraron no revelarlo. Se percibió tanto el apoyo como la falta de apoyo a partir de las revelaciones. La no revelación fue motivada por la autopreservación y por la evitación de presión social. Los hallazgos indican la importancia de la intervención psicológica para ampliar el apoyo social de las parejas.

Este estudo de casos múltiplos, que envolveu a coleta de dados sociodemográficos, de saúde e entrevistas com quatro casais heterossexuais acessados por conveniência, objetivou examinar a sua percepção sobre o apoio social recebido após a revelação da condição de infertilidade e/ou de tratamento com técnicas de reprodução assistida. Os casos foram analisados individualmente e comparativamente. A partir das falas, destaca-se que todos revelaram algo sobre a infertilidade e/ou o tratamento em algum momento do processo, ainda que alguns tenham considerado não revelar. Percebeu-se tanto apoio como falta de apoio diante das revelações. A não revelação foi motivada pela autopreservação e pela evitação de pressão social. Os achados indicam a importância da intervenção psicológica para ampliar o apoio social dos casais.

Objective: To investigate the relationship between magnetic resonance imaging (MRI) imaging characteristics and clinical symptoms and therapeutic efficacy in adenomyosis patients. Methods: The clinical characteristics of the adenomyosis questionnaire was self-designed. This was a retrospective study. From September 2015 to September 2020, totally 459 patients were diagnosed with adenomyosis and underwent pelvic MRI examination at Peking University Third Hospital. Clinical characteristics and treatment were collected, MRI was used to determine the lesion location, and to measure the maximum lesion thickness, the maximum myometrium thickness, uterine cavity length, uterine volume, the minimum distance between the lesion and serosa or endometrium, and whether combined with ovarian endometrioma. The difference of MRI imaging characteristics in patients with adenomyosis and its relationship with clinical symptoms and therapeutic efficacy were analyzed. Results: (1) Among the 459 patients, the age was (39.1±6.4) years. There were 376 patients (81.9%, 376/459) with dysmenorrhea. Whether patients had dysmenorrhea were related to uterine cavity length, uterine volume, ratio of the maximum lesion thickness to the maximum myometrium thickness, and whether patients had ovarian endometrioma (all P<0.001). Multivariate analysis suggested that ovarian endometrioma was the risk factor for dysmenorrhea (OR=0.438, 95%CI: 0.226-0.850, P=0.015). There were 195 patients (42.5%, 195/459) with menorrhagia. Whether patients had menorrhagia were related to age, whether patients had ovarian endometrioma, uterine cavity length, the minimum distance between lesion and endometrium or serosa, uterine volume, ratio of the maximum lesion thickness to the maximum myometrium thickness (all P<0.001). Multivariate analysis suggested that ratio of the maximum lesion thickness to the maximum myometrium thickness was the risk factor for menorrhagia (OR=774.791, 95%CI: 3.500-1.715×105, P=0.016). There were 145 patients (31.6%, 145/459) with infertility. Whether the patients had infertility were related to age, the minimum distance between lesion and endometrium or serosa, and whether patients had ovarian endometrioma (all P<0.01). Multivariate analysis suggested that young and large uterine volume were risk factors for infertility (OR=0.845, 95%CI: 0.809-0.882, P<0.001; OR=1.001, 95%CI: 1.000-1.002, P=0.009). (2) The success rate of in vitro fertilization-embryo transfer (IVF-ET) was 39.2% (20/51). Dysmenorrhea, high maximum visual analogue scale score and large uterine volume affected the success rate of IVF-ET (all P<0.05). The smaller the maximum lesion thickness, the smaller the distance between the lesion and serosa, the larger the distance between the lesion and endometrium, the smaller the uterine volume, and the smaller the ratio of the maximum lesion thickness to the maximum myometrium thickness, the better the therapeutic efficacy of progesterones (all P<0.05). Conclusions: Concomitant ovarian endometrioma increases the risk of dysmenorrhea in patients with adenomyosis. The ratio of the maximum lesion thickness to the maximum myometrium thickness is an independent risk factor for menorrhagia. Young and large uterine volume may increase the risk of infertility. Severe dysmenorrhea and large uterine volume affect the success rate of IVF-ET. The therapeutic efficacy of progesterones is relatively better when the lesion is small and far away from the endometrium.

Mycoplasma species (spp.) are bacteria that are difficult to detect. Currently, the polymerase chain reaction (PCR) is considered the most effective diagnostic tool to detect these microorganisms in both human and veterinary medicine. There are 13 known species of human Mycoplasma and 15 species of canine Mycoplasma. Owing to the difficulties in identifying the individual species of Mycoplasma, there is a lack of information regarding which species are saprophytic and which are pathogenic. The prevalence of the individual species is also unknown. In addition, in both humans and dogs, the results of some studies on the impact of Mycoplasma are conflicting. The presence of Mycoplasma spp. on the epithelium of reproductive tract is often associated with infertility, although they are also detected in healthy individuals. The occurrence of Mycoplasma spp. is more common in dogs (even 89%) than in humans (1.3%-4%). This is probably because the pH of a dog's genital is more conducive to the growth of Mycoplasma spp. than that of humans. Phylogenetically, human and canine Mycoplasma are related, and majority of them belong to the same taxonomic group. Furthermore, 40% of canine Mycoplasma spp. are placed in common clusters with those of human. This suggests that species from the same cluster can play a similar role in the canine and human reproductive tracts. This review summarizes the current state of knowledge about the impact of Mycoplasma on canine and human male fertility as well as the prospects of further development in this field.

@#Leydig cell tumor is a rare testicular neoplasm that can present as a non-palpable small testicular nodule. Here we present a case of a 36-year-old Filipino male who initially came in for fertility work-up. Semen analysis showed azoospermia. However, an incidental finding on ultrasound showed a well-circumscribed round tumor. The patient underwent radical orchiectomy. On histopathologic examination, a Leydig cell tumor was identified and supported by immunohistochemical staining. We discuss the clinical features pathogenesis, treatment, diagnosis and prognosis of this uncommon entity.

Abstract Dill (Anethum graveolens L.) essential oil is wide spread in the food, beverage and pharmaceutical sectors. Dill is a member of the Apiaceae (Umbelliferae) family. It has the following biological activities: antioxidant, antifungal, antibacterial, antimicrobial, antihyperlipidemic, antihypercholesterolemic, antispasmodic, antiproliferative and anti-inflammatory. Aqueous extract of dill seed has reported effects on sex hormones and infertility potential. Moreover, boiled dill seed has an impact on reducing labor duration in giving birth. Implantation and placentation are necessary for a healthy pregnancy in the early stages. Angiogenesis is responsible for these essential processes. This study aimed to investigate dill seed oil's cytotoxic and antiangiogenic effects on rat adipose tissue endothelial cells (RATECs). Dill seed oil showed dose-dependent cytotoxicity on RATECs. It disrupted endothelial tube formation and depolymerized F-actin stress fibers. According to this study, depolymerization of F-actin stress fiber by dill seed oil could inhibit angiogenesis by suppressing endothelial cell proliferation, tube formation and motility. In other words, dill seed oil can be a new anti-angiogenic agent and a novel contraceptive.

Com os avanços tecnológicos e o aprimoramento da prática médica via ultrassonografia, já é possível detectar possíveis problemas no feto desde a gestação. O objetivo deste estudo foi analisar a prática do psicólogo no contexto de gestações que envolvem riscos fetais. Trata-se de um estudo qualitativo sob formato de relato de experiência como psicólogo residente no Serviço de Medicina Fetal da Maternidade Escola da Universidade Federal do Rio de Janeiro (UFRJ). Os registros, feitos por observação participante e diário de campo, foram analisados em dois eixos temáticos: 1) intervenções psicológicas no trabalho em equipe em consulta de pré-natal, exame de ultrassonografia e procedimento de amniocentese; e 2) intervenções psicológicas em casos de bebês incompatíveis com a vida. Os resultados indicaram que o psicólogo nesse serviço é essencial para atuar de forma multiprofissional na assistência pré-natal para gravidezes de alto risco fetal. Ademais, a preceptoria do residente é relevante para sua formação e treinamento para atuação profissional no campo da psicologia perinatal.(AU)

Face to the technological advances and the improvement of medical practice via ultrasound, it is already possible to detect possible problems in the fetus since pregnancy. The objective of this study was to analyze the psychologist's practice in the context of pregnancies which involve fetal risks. It is a qualitative study based on an experience report as a psychologist trainee at the Fetal Medicine Service of the Maternity School of UFRJ. The records, based on the participant observation and field diary, were analyzed in two thematic axes: 1) psychological interventions in the teamwork in the prenatal attendance, ultrasound examination and amniocentesis procedure; and 2) psychological interventions in cases of babies incompatible to the life. The results indicated that the psychologist in this service is essential to work in a multidisciplinary way at the prenatal care for high fetal risk pregnancies. Furthermore, the resident's preceptorship is relevant to their education and training for professional performance in the field of Perinatal Psychology.(AU)

INTRODUCCIÓN: La infertilidad es una enfermedad multicausal y el componente genético representa uno de sus principales eventos. Si bien la distribución de la infertilidad puede variar entre poblaciones, las parejas de los países con bajos y medianos ingresos pueden verse más afectadas por la infertilidad, con una proporción de alteraciones citogenéticas aún no esclarecidas. OBJETIVO: Evaluar la frecuencia de alteraciones citogenéticas y su correlación con el número de abortos en pacientes peruanas con diagnóstico de infertilidad. MÉTODO: Se realizó un estudio de corte transversal en 400 pacientes de 18 a 60 años, de ambos sexos, con diagnóstico de infertilidad. Se registraron las características clínicas disponibles durante el examen genético y el análisis citogenético convencional fue con bandeo GTG en muestras de sangre periférica. El análisis de correlación se realizó con la prueba de Spearman. RESULTADOS: Del total, 389 pacientes cumplieron los criterios de inclusión, y de estos, 169 (43,44%) tuvieron reportes de abortos (promedio: 2,25, rango: 1-7). Hallamos una correlación significativa ente el número de abortos y las alteraciones citogenéticas (p < 0,000). Reportamos 25/289 (6,43%) alteraciones cromosómicas, de las que 11/25 (44%) fueron heterocromatinas constitutivas y 6/25 (24%) fueron translocaciones reciprocas. Las alteraciones citogenéticas más frecuentes fueron 16qh+ y 9qh+ (ambas con un 16%), y afectaron a 17 (68%) varones. CONCLUSIONES: Existe una moderada frecuencia de alteraciones citogenéticas en pacientes peruanos con diagnóstico de infertilidad, y las alteraciones más frecuentes fueron heterocromatina constitutivas. Además, evidenciamos una correlación significativa ente el número de abortos y las alteraciones citogenéticas.

INTRODUCTION: Infertility is a multicausal disease and the genetic component represents one of its main events. Although the distribution of infertility may vary between populations, couples in low-and-middle-income countries may be more affected by infertility with a proportion of cytogenetic alterations still unclear. OBJECTIVE: To evaluate the frequency of cytogenetic alterations and their correlation with the number of abortions in Peruvian patients with a diagnosis of infertility. METHOD: A cross-sectional study was carried out in 400 patients between 18 and 60 years-old, of both genders with a diagnosis of infertility. The clinical characteristics available during the genetic examination were recorded and the conventional cytogenetic analysis was with GTG banding in peripheral blood samples. The correlation analysis was performed with the Spearman test. RESULTS: Of the total 389 patients who met the inclusion criteria, of these 169 (43.44%) patients had reports of abortions (mean: 2.25, range: 1-7). We found a significant correlation between the number of abortions and cytogenetic alterations (p < 0.000). We report 25/289 (6.43%) chromosomal alterations, where 11/25 (44%) were constitutive heterochromatin, and 6/25 (24%) were reciprocal translocations. The most frequent cytogenetic alterations were 16qh + and 9qh + (both 16%), and affected 17 (68%) men. CONCLUSIONS: There is a moderate frequency of cytogenetic alterations in Peruvian patients diagnosed with infertility, where the most frequent alterations were constitutive heterochromatin. Furthermore, we evidenced a significant correlation between the number of abortions and cytogenetic alterations.

OBJETIVO: Describir las tasas de recién nacidos vivos (RNV) y embarazo de la terapia de reproducción médicamente asistida de baja complejidad del Centro de Reproducción Humana de la Universidad de Valparaíso, Chile. MÉTODO: Estudio retrospectivo de todos los ciclos de estimulación ovárica controlada con inseminación intrauterina (IIU) completados, entre los años 2011 y 2019. Se evaluaron las características clínicas basales y los resultados en IIU homólogas y heterólogas según el ciclo inseminado, la causa de infertilidad, el rango etario y el índice de masa corporal (IMC). El desenlace principal fue la tasa de RNV por ciclo inseminado. RESULTADOS: Se estudiaron 1415 ciclos en 700 parejas. La tasa acumulativa de RNV fue del 19,6%, un 18,3% en IIU homóloga y un 39,0% en IIU heteróloga. La tasa de RNV fue del 10,0% al primer ciclo, del 5,8% al segundo ciclo y del 3,7% al tercer o más ciclos. Al separar por IIU heteróloga, esta aumenta al 24,4% al primer ciclo y al 14,6% al segundo ciclo. La tasa de RNV es significativamente mejor en pacientes menores de 35 años (23,7%) y con IMC < 29 (20,8%). CONCLUSIONES: El tratamiento de baja complejidad en pacientes infértiles es una opción terapéutica vigente con una aceptable tasa de RNV por ciclo inseminado. Los resultados están influenciados por la edad y por el IMC.

OBJECTIVE: To describe the rates of live newborns (LNB) and pregnancy of the low complexity therapy of the Centre for Human Reproduction of Universidad de Valparaíso, Chile. METHOD: Retrospective study of all cycles of controlled ovarian stimulation with intrauterine insemination (IUI) completed between 2011-2019. The baseline clinical characteristics and results in homologous and heterologous IUI were evaluated according to inseminated cycle, cause of infertility, age range and body mass index (BMI). The main outcome was rate of LNB per inseminated cycle. RESULTS: 1415 cycles were studied in 700 couples. The cumulative rate of LNB was 19.6%, 18.3% in homologous IUI and 39.0% in heterologous IUI. The LNB rate was 10.0% at the first cycle, 5.8% at the second cycle, 3.7% at the third or more cycles. When separating by heterologous IUI, it increases to 24.4% in the first cycle and 14.6% in the second cycle. The LNB rate is significantly better in patients under 35 years of age (23.7%) and with a BMI less than 29 (20.8%). CONCLUSIONS: Treatment of low complexity in selected infertile patients is a current therapeutic option with an acceptable rate of LNB per inseminated cycle. The results are influenced by age and BMI.

SUMMARY OBJECTIVE: Since the start of the COVID-19 pandemic, there has been interest in the impact of both SARS-CoV-2 infection and pandemic-induced social restrictions on male reproductive health. This study aimed to evaluate the spermiogram values of men who presented for infertility during the pandemic compared with the previous 2 years. METHODS: Patients who presented to a urology outpatient clinic for the first time due to infertility were included. The patients' age, semen volume, and spermiogram results were recorded. Based on the presentation date, the patients were divided into prepandemic group 1 (March 2018-February 2019), prepandemic group 2 (March 2019-February 2020), and pandemic group (March 2020-February 2021) for comparison. RESULTS: A total of 594 patients were included. There was no significant difference between the three groups in terms of the number of patients who presented for infertility (207, 190, and 197 patients, respectively; p=0.691). The mean age was 36.6±7.2 in the prepandemic group 1, 35.5±7.1 in the prepandemic group 2, and 33.1±6.3 in the pandemic group. Patients who presented during the pandemic were significantly younger (p<0.001). There were no differences between the groups in terms of semen volume (p=0.910) or rates of normospermia and pathological spermiogram findings (p=0.222). CONCLUSIONS: In the first year of the COVID-19 pandemic, there was no significant difference in the number of patients who presented for infertility or in their spermiogram results compared with 2018 and 2019. However, it is noteworthy that the patients were significantly younger during the pandemic than in the previous 2 years.

Relatively little is known about infertility experiences among women in rural Malawi and the impact of infertility on women's marital and family relations. This article examines the perspectives of women and health care providers regarding women's concepts of reproductive health and attitudes toward infertility. The paper explores the supports and barriers to managing infertility at the individual, household, and community levels. The data presented was drawn from semi-structured interviews with health care providers and patients within a prevention of mother to child transmission program and focus group discussions with community men and women in four communities in Southern Malawi. Seventy-eight patients, 12 health care providers, and 32 community leaders participated in the study. The findings suggest that gender inequities and kinship relations intersect to produce infertility related stigma which exacerbates the social and cultural consequences of being infertile in these study communities. Social support from other women experiencing infertility is one strategy to help women manage the social and cultural burden of infertility in these study communities. These results shed light on the meaning of motherhood to women living in rural and periurban Sub-Saharan African communities and call for an expansion of infertility services, social services, and mental health services for both women and men who experience infertility. (Afr J Reprod Health 2022; 26[7]: 112-126).

In sub-Saharan Africa, traditional medical practitioners also referred to as herbalists, offer diagnostics and therapeutics for diverse medical conditions irrespective of the cause. Given their traditional role as healers and repository of knowledge about medicinal plants, spirituality, customs and religion, people use their services regardless of their location, education, or socio-economic backgrounds. The aim of the study is to explore herbalists´ views and explanations on infertility and women with infertility. Using an exploratory qualitative design, semi-structured interviews were conducted with 10 herbalists, 5 from the North-East region, 2 from Ashanti region and 3 from the Greater Accra region. Following thematic analysis, findings show that infertility has multiple causes - medical, natural, spiritual and lifestyle. Some herbalists stated that everyone was created to bear children while others refuted this notion. They shared the common consensus that not everyone can have children even though they may be medically and spiritually fit. The public should be advised on the need for periodic reproductive health checks. Also, there should be a conscious, concerted efforts to gradually dissociate unhealthy explanations of infertility from the actual empirically proven realities.This would empower society to rise above those entrenched beliefs, thereby reducing the stigma associated with infertility and women with infertility. (Afr J Reprod Health 2022; 26[5]: 96-106).

OBJECTIVE@#To evaluate the influence of different transcutaneous electrical acupoint stimulation (TEAS) modes on ovarian responses and pregnancy outcomes in patients with infertility undergoing in vitro fertilization and embryo transfer (IVF-ET).@*METHODS@#Two hundred infertility patients undergoing IVF-ET were divided randomly into experimental groups (TEAS groups: E-I, E-II, E-III, and E-IV, 40 cases each group) and a control group (mock TEAS group, 40 patients) using the random number method. The patients in the experimental groups received TEAS treatment of 20, 30, 40 and 50 mA for the E-I, E-II, E-III and E-IV groups, respectively. The control group received a treatment of 5 mA. TEAS was applied at acupoints of Guanyuan (RN 4), Zhongji (RN 3), Sanyinjiao (SP 6), Zigong (EX-CA 1), and Taixi (KI 13), once a day for 30 min each time for a treatment period of 10-13 d. Treatment effect was assessed using the following indicators: endometrial thickness on the 6th day of gonadotropin treatment (GN6 day), endometrial thickness on the day on chorionic gonadotropin administration (HCG day), number of ovarian follicles on HCG day, number of ova captured, amount of estrogen required for each harvested ova, number of mature ova divided by the total number of ova, percentage of high-quality embryos, and clinical pregnancy.@*RESULTS@#Endometrial thickness in the experimental groups on the HCG day was significantly better than that of the control group after TEAS stimulation (P=0.01). TEAS exhibited a greater impact on the number of ova captured (P=0.003). However, the effect of TEAS stimulation on the high-quality embryo rate and clinical pregnancy in patients was not statistically significant (P>0.05).@*CONCLUSIONS@#TEAS is an effective method in improving the ovarian state. When the stimulus intensity was at 40 mA and above, it could be helpful to improve the patient's endometrial condition and endometrial receptivity and to retrieve more oocytes.

OBJECTIVE@#Utilize high-resolution chromosome analysis and microarray detection to determine the genetic etiology of infertility of a 32-year old female patient.@*METHODS@#The peripheral blood of the patient was cultured for high-resolution chromosome G and C banding karyotype analysis, and then 750K SNP-Array chip detection was performed.@*RESULTS@#Karyotype analysis results showed that the patient's karyotype was 45,XX,-13 [7]/46,XX,r(13) (p13q34) [185]/46,XX,dic r(13;13)(p13q34;p13q34) [14]/ 47,XX,+der(13;13;13;13) (p13q34;p13q34;p13q34; p13q34), dic r(13;13) [1]/ 46,XX [3]. The microarray results showed that the patient had a 3.3 Mb deletion in the 13q34 segment of chromosome 13, which may be related to infertility.@*CONCLUSION@#Infertility of the patient reported in this article may be related to the deletion of chromosome segment (13q34-qter).

This paper discussed the guiding significance of "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) for dealing with ovulation disorder infertility caused by hyperprolactinemia(HPRL). FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) concentrates on the disease entities, main symptoms, pathogenesis, and syndrome differentiation, based on which the prescriptions are prescribed. This reflects the "disease-syndrome-symptom" mode, with the core lying in the "combination of disease with syndrome". The contained Discussion on Menstruation Regulation(Tiao Jing Pian) and Discussion on Getting Pregnant(Zhong Zi Pian) have important reference significance for later doctors in the diagnosis and treatment of inferti-lity, and many prescriptions are still in use due to good effects. It is believed in traditional Chinese medicine(TCM) that HPRL results from kidney deficiency and liver depression, among which kidney deficiency is the main cause. Liver depression accelerates the onset of HPRL, so the kidney-tonifying and liver-soothing herbs were mainly selected. The "disease-syndrome-symptom" mode in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) sheds enlightenment on the diagnosis and treatment of ovulation infertility caused by HPRL, in that it is not confined to disease entity and syndrome type. The integration of "disease-syndrome-symptom" highlights the main complaint of patients and emphasizes the main pathogenesis, thus giving full play to the overall advantage of syndrome differentiation. For multiple diseases in FU Qing-zhu's Obstetrics and Gynecology(FU Qing-zhu Nyu Ke) such as infertility due to liver depression, infertility due to obesity, delayed menstruation, and irregular menstruation, although the typical lactation symptom of HPRL is not mentioned, the medication can still be determined according to the chief complaint, syndrome type, and symptoms and signs, making up for the defects of excessive reliance on serum biochemical indicators in modern Chinese medicine. We should learn its diagnosis and treatment thoughts of paying attention to liver, spleen, kidney, and heart, holism, and strengthening body resistance to eliminate pathogenic factors.

To summarize LIU Zhi-shun's clinical experience in treatment of infertility with decreasing ovarian reserve (DOR) with electroacupuncture. LIU Zhi-shun believes that the location of infertility with DOR is the uterus, mainly involving the kidney, thoroughfare and conception vessels. He advocates to select acupoints by combining "disease-symptom-position" with prescription, and selects acupoint prescription of Bushen Tiaochong Zhuyun included Guanyuan (CV 4), Zigong (EX-CA 1), Tianshu (ST 25), Sanyinjiao (SP 6), Ciliao (BL 32) and Zhongliao (BL 33) for electroacupuncture treatment. The key points of operation are accurate positioning and deep acupuncture, focusing on regulating mind and getting qi, adopting electroacupuncture treatment and low frequency stimulation and treating slowly for long-term disease.
