Effects of clomiphene citrate on seminal parameters in idiopathic oligospermia: a single blinded prospective randomized controlled trial

Background: About 15% married couples face problem of infertility of which male factor is implicated in 20% of them. In about 30% infertile men no causative factor is found and the condition is termed “Idiopathic”. They are often treated by empirical medications or Assisted Reproductive Technologies (ART) although success in few; our present study is carried on effects of clomephene citrate on seminal parameters in idiopathic oligospermia.Methods: This single blinded prospective randomized controlled trial was conducted at the infertility clinic with 200 idiopathic oligospermic men (sperm count <15 millions/ ml of ejaculate) after fulfilling inclusion and exclusion criteria and were alternately allocated into two equal groups - “Group C” receiving clomephene citrate tablets and “ Group P” receiving placebo after concealment. Semen analysis data were collected at baseline and every month and three months of completion of treatment and were summarized by routine descriptive statistical analysis.Results: The demographic characteristics like mean age is comparative in both groups but duration of infertility of >2 years is more in group C than group p (4.3±3.06 versus 4.1±2.57). The semen volume, spermatozoa count, sperm motility and not normal form are all increased after three months of treatment in group C as are biochemical parameters like total testosterone and serum FSH, LH and as also pregnancy rate (22% versus 4%).Conclusions: This study showed clomiphene citrate treatment protocol is inexpensive, relatively safe and easy to administer and improves semen volume, sperm count and sperm motility but not sperm morphology by increasing serum testosterone, FSH and LH in male and resulting in improved pregnancy rate in female partners.

Semen analysis and sperm function parameters in patients with infertility in Navi Mumbai and Panvel region

Background: Although semen analysis is routinely used to evaluate male partner in infertile couples, infertility and problems of impaired fecundity have been a concern through ages and is also a significant clinical problem today, which affects 8-12% of couples worldwide. Aim of the study was to study different semen parameters in male factor infertility (MFI) and thus increasing the awareness regarding same.Methods: This is cross sectional study conducted between period of September 2016 to December 2018. Semen of 150 patients were studied and results were analysed as per recent WHO (2010) criteria.Results: The present study included 150 patients whose age ranged from 24 to 51 years. Patients were divided into different age groups and sperm count was studied in each group. Abnormal sperm morphology was studied with respect to sperm head, neck, tail defects and combined defects. Sperm deformity index (SDI) and Teratozoospermic index (TZI) were calculated. Other parameters including semen volume, pH, liquefaction time, sperm vitality and motility were also studied which showed significant variations. Conclusions: Although semen analysis is first and most informative investigation for evaluation of male factor infertility, studying individual semen parameters and sperm function and increasing its awareness in general population especially in developing countries is equally important. Besides, it is necessary to acknowledge its limitation with respect to collection, processing, evaluation and biological variation of samples. Also, a normal semen analysis may not prove successful fertility potential of an individual.

Role of Measurement of Reactive Oxygen Species in Semen Sample of Patients with Male Factor Infertility and Treatment with Antioxidants in Patients with High ROS Levels

Introduction: It is a known fact that human sperms, producereactive oxygen species in small amounts, which is usefulfor normal functioning of the sperm mainly sperm oocyteinteraction acrosome reaction and capacitation. Recentresearch has shown that this ROS in increased amounts is acause of male infertility.Material and methods: It is a prospective control trial todetermine the abnormal pattern of reactive oxygen speciesin semen sample of patients with male factor infertility andto determine the effects of antioxidants in semen sampleof patients with high ROS in semen sample. 150 patientswere selected who were undergoing IVF treatment. Patientswere divided into three groups according to the severity ofabnormality in the semen analysis. The ROS levels of all thepatients were measured and compared with 50 normal fertiledonors. The patients whose ROS levels was found to be highwere then given antioxidants for 2 months and their ROSlevels in semen measured for improvement.Results: The ROS levels were significantly high in all thethree groups compared to fertile donors. The patients withhigh R0S levels were then treated with antioxidants and it wasseen that all the three groups had significant improvement intheir ROS levels.Conclusion: So, to conclude it is hence proved by my studythat ROS level measurement is useful for patients with malefactor infertility and the use of antioxidants significantly helpsin reducing ROS levels in semen.

Chronic epididymitis and Grade III varicocele and their associations with semen characteristics in men consulting for couple infertility / 亚洲男科学杂志(英文版)

Chronic epididymitis and varicocele are frequently observed genital disorders in men consulting for couple infertility, but their impact on semen characteristics at the time of infertility consultation is still a matter of debate. We investigated 652 male partners of couples who had their first infertility consultation between 1999 and 2015 in Argentina. Men with chronic epididymitis (n = 253), Grade III varicocele (n = 106), and both conditions (n = 125) were compared with a control group (n = 168) composed of men without these disorders or any other recognized causes of male infertility. We showed that men who presented isolated chronic epididymitis were more likely to have high percentages of low sperm motility and abnormal sperm morphology as well as a high number of white blood cells. Men with isolated Grade III varicocele had low sperm production and motility and an increased percentage of abnormal sperm morphology. Finally, men who simultaneously presented chronic epididymitis with Grade III varicocele had a low sperm motility and increased percentage of abnormal sperm morphology as well as a high number of white blood cells. Physical examination of the genital organs may identify common disorders, potentially involved as causal factors of patient's infertility. These disorders are associated with specific seminal profiles that should help in identifying the best treatment from the available therapeutic options, effectiveness, safety, and allowing as much as possible natural conception.

Successful treatment of severe male factor infertility in Jamaica with intracytoplasmic sperm injection / Tratamiento exitoso de la infertilidad severa por factor masculino en Jamaica mediante inyección de esperma intracitoplasmático

OBJECTIVES: To examine the impact of intracytoplasmic sperm injection (ICSI) on the treatment of subfertile couples in Jamaica. METHOD: A review of the outcome of treatment cycles for infertile couples that underwent in-vitro fertilisation (IVF) and ICSI from 2003-05 at the Hugh Wynter Fertility Management Unit (HWFMU) of the University of the West Indies. Fertilisation and pregnancy rates for the cycles as well as the factors determining the success of the procedure were reviewed. SPSS 11.1 was used to do statistical calculations. RESULTS: Ninety-six ICSI cycles were done from January 1, 2003 to December 31, 2005. For couples with previous poor or no fertilisation in a standard IVF group (n = 12), the fertilisation rate was 72%; for those with substandard semen (n = 73), the fertilisation rate was 77.5%, for those with semen retrieved by surgical sperm method (n = 11), the fertilisation rate was 59%. The resulting live births were 0%, 12.5% and 27.3% respectively. There was a statistically significant impact ofage on pregnancy rates as the mean age ofthe females in the previously poor or no fertilisation in a standard IVF group (39.08 ± 5.14) was greater than those of the substandard semen group (35.93 ± 4.22) ]p = 0.023[ as well as the group with surgical sperm retrieval (32.82 ± 6.65) ]p = 0.019[. CONCLUSION: With ICSI, the fertilisation and pregnancy rates in Jamaica are comparable to international rates regardless of the cause of infertility. However, the age of the female partner does have a significant impact on the pregnancy rate following ICSI.

OBJETIVO: Examinar el impacto de la inyección de esperma intracitoplasmático (IEIC) en el tratamiento de las parejas subfértiles en Jamaica. MÉTODO: Se realizó un examen del resultado de los ciclos de tratamiento para las parejas infértiles que recurrieron a la fertilización in vitro (FIV) y a la IEIC de 2003 a 2005 en la Unidad de Tratamiento de la Fertilidad Hugh Wynter del Hospital Universitario de West Indies (HWFMU). Se examinaron las tasas de fertilización y embarazos en todos los ciclos así como los factores que determinan el éxito del procedimiento. Se usó el programa SPSS para realizar los cálculos estadísticos. RESULTADOS: Se realizaron noventa y seis ciclos de IEIC del 1ero de enero de 2003, al 31 de diciembre de 2005. Para parejas con ninguna o pobre fertilización en un grupo estándar de FIV (n - 12), la tasa de fertilización fue 72%; para aquellos con semen subestándar (n = 73), la tasa de fertilización fue 77.5%; para aquellos con semen recuperado mediante recuperación quirúrgica de esperma (n = 11), la tasa de fertilización fue 59%. Los nacimientos vivos resultantes fueron 0%, 12.5%, y 27.3% respectivamente. Hubo un impacto estadísticamente significativo de la edad sobre las tasas de comembarazo, ya que la edad promedio de las hembras en la fertilización previamente pobre o sin fertilización en un grupo FIV estándar (39.08 ± 5.14) fue mayor para las del grupo de semen subestándar (35.93 ± 4.22) ]p = 0.023[ así como las del grupo con recuperación quirúrgica del esperma (32.82 ± 6.65) ]p = 0.019[. CONCLUSIÓN: Con el uso de IEIC, las tasas de fertilización y embarazo en Jamaica, son comparables a las tasas internacionales, independientemente de cual sea la causa de la infertilidad. Sin embargo, la edad de la pareja hembra no tiene un impacto significativo sobre la tasa de embarazo una vez aplicada la IEIC.

Analysis of Strict Morphology of Human Spermatozoa / 대한산부인과학회잡지

The proportion of male factor infertility due to quantitative and qualitative sperm disorders is approximately 50-60% in infertile couples. In IVF-ET, lower or failed fertilization of oocytes usually results from subnormal count of total motile sperms, but this may occur in infertile couples even with normal sperm count. It has been suggested that some functional defects in sperms are responsible for lower or failed fertilization. Routine semen analysis based on numerical background has limits for the assessment of fertilization capacity of sperm in infertile males, and the andrologic test for the prediction of fertilization capacity must be objective, repeatable, quick, economic, and easily applicable for the clinical settings. The purposes of this study were to develop the analysis method of strict morphology of sperm using the strict criteria as a simple, inexpensive and useful test of sperm fertilization capacity, to establish the normal fertile range and the cut-off value of strict morphology, and to evaluate the validity of strict morphology as a prognostic indicator of fertilization capacity in IVF-ET. In establishing the effectiveness of strict morphology of sperm, ROC curve was used. Among the various thresholds for the prediction of fertilizing ability, normal morphologic value 10.0 corresponding to the value with higher sensitivity and lesser false positive rates was determined as a cut-off value. Using this cut-off point, the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of strict morphology for the prediction of fertilization capacity was 73.9%, 81.0%, 80.6%, and 72.7%, respectively. To evaluate the clinical validity of strict morphology as a prognostic indicator of fertilization capacity, this cut-off point was applied to 133 patients undergoing IVF-ET. For the prediction of fertilization rate >30% in IVF-ET, the sensitivity, specificity, PPV, and NPV was 77.3%, 77.8%, 87.2%, and 63.6%, respectively. In conclusion, the strict morphology of sperm is one of the most simple and useful test for the assessment of fertilization capacity of sperm and the prediction of IVF-ET outcomes in infertile couples.

Microassisted Fertilization of Human Oocytes with Intracytoplasmic Sperm Injection in In VitroFertilization Program / 대한산부인과학회잡지

In spite of much progress in in vitro fertilization and embryo transfer(IVF-ET) program,the pregnancy rate remains at 20~30%, and the endometrial implantation rate per embryotransferred at 10%. Although IVF-ET is widely applied in the treatment of coupleswith male factor infertility, it may fail in many infertile couples with normal semen parameters,and certain couples cannot be accepted for standard IVF-ET due to unfertilization orextremely low fertilization rate of oocytes. Recently, several procedures of microassistedfertilization(MAF) using micromanipulation have been introduced, and pregnancies and birthshave been obtained after intracytoplasmic sperm injection(ICSI).This clinical study was performed to develop and establish ICSI as an effective procedureof MAF in infertile couples who could not be accepted for standard IVF-ET becauseof extremely impaired semen characteristics(Group A) and because of failure in fertilizationof extremely low fertilization rate of oocytes with the conventional fertilization technique inthe previous IVF-ET cycles(Group B). From March, 1995 to December, 1996, a total of 114cycles of IVF-ET with ICSI in 65 infertile patients were included in study group, and theoutcomes of ICSI were analyzed according to fertilization rate, cumulative embryo score(CES), and pregnancy rate.In Group A, 34 patients were evaluated with semen score such as number of totalmotile sperms, and then divided into 4 groups accordingly. In 62 ICSI cycles, the numberof oocytes retrieved after controlled ovarian hyperstimulation(COH) was 12.4+/-6.8, and thenumber of oocytes optimal for ICSI procedure was 8.8+/-5.5. The fertilization rate of 65.7+/-23.6% could be obtained after ICSI. The number of embryos transferred was 4.4+/-2.2 withthe mean CES of 50.5+/-34.3 in ICSI cycles. The overall pregnancy rate was 24.2%(15/62)per cycle and 44.1%(15/34) per patient. There were no significant differences in the pregnancyrates among 4 groups. Although more mature oocytes were retrieved, the fertilizationrate was significantly lower in Group A-1 compared with Group A-IV. However, semenscore did not clearly affect the outcomes of ICSI in couples with severe male factor infertility.In Group B, the number of oocytes retrieved after COH was 10.5+/-6.1 in 49 previouscycles, and 10.8+/-5.7 in 52 ICSI cycles. In ICSI cycles, the number of oocytes optimal forICSI procedure was 8.5+/-5.1 with the fertilization rate of 72.4+/-22.5%. The number ofembryos transferred was 1.4+/-2.4 in previous cycles, and 4.7+/-1.8 with the mean CES of 50.4+/-29.9 in ICSI cycles. In ICSI cycles, the overall pregnancy rate was 30.8%(16/52) percycles and 51.6%(16/31) per patients.In conclusion, MAF of human oocytes with ICSI is a promising fertilization method forIVF-ET patients, especially with few spermatozoa for the conventional methods of in vitroinsemination and with the past history of failure in fertilization or low fertilization rate inthe previous cycles, and ICSI using micromanipulation procedures applied to human oocyteswill provide a range of novel techniques which may dramatically improve the pregnancy ratein IVF-ET program and contribute much to the effective management of infertile couples.
