Assisted reproductive technology outcomes in azoospermic men: 10 years of experience with surgical sperm retrieval

Comparing the clinical and singleton neonatal outcomes in male infertility patients with Oligoasthenospermia, OA, or NOA following fresh ICSI-ET using different sources of sperm

Objective

To investigate clinical and singleton newborn outcomes in fresh cycles of embryo transfer after intracytoplasmic sperm injection (ICSI-ET) with diverse sperm sources (ejaculate, epididymis, and testis) in patients with Oligoasthenospermia, obstructive azoospermia (OA) or non-obstructive azoospermia (NOA).

Methods

Patients who received fresh ICSI-ET for the first time at the First Affiliated Hospital of Zhengzhou University Reproductive Medicine Center between June 2011 and June 2021 were selected for this 10-year retrospective cohort analysis. After propensity score matching, only 1630 cycles were included in the investigation of ICS-ET clinical and singleton newborn outcomes in patients with Oligoasthenospermia, OA, and NOA using sperm from diverse sperm sources.

Results

After propensity score matching, our data revealed a negligible difference in baseline and cycle parameters among groups. In patients with Oligoasthenospermia and OA, different sperm sources do not appear to influence clinical pregnancy rates and live birth rates, nor do they influence newborn outcomes, such as newborn weight, premature birth rate, and neonatal sex ratio in singleton births, except for OA patients who use epididymal sperm having higher low birth weight (LBW) rates in singleton pregnancies than those who use testicular sperm. In addition, clinical pregnancy rates, live birth rates, singleton gestation birth weights, premature birth rates, and neonatal sex ratios were similar between patients with Oligoasthenospermia, OA, and NOA using testicular sperm.

Conclusions

Regardless of the type of male infertility (Oligoasthenospermia, OA, NOA) or sperm sources (ejaculate, epididymis, testis), a successful ICSI-ET procedure can result in similar clinical and neonatal outcomes, such as clinical pregnancy rate, live birth rate, abortion rate, neonatal birth weight and sex ratio of singleton pregnancies.

Reproductive outcomes after surgical sperm retrieval in couples with male factor subfertility: a 10-year retrospective national cohort

OBJECTIVE

To determine any significant differences in the reproductive outcome from intracytoplasmic sperm injection (ICSI) with surgical sperm retrieval (SSR) between cycles using fresh and cryopreserved sperm and between cycles using epididymal and testicular sperm.

DESIGN

A retrospective national cohort study using data from the UK Human Fertilisation and Embryology Authority, including all ICSI cycles performed in the United Kingdom over a 10-year period.

SETTING

Hospital.

PATIENT(S)

All nondonor ICSI cycles from 2008 to 2017 categorized by sperm source and cryopreservation status.

INTERVENTION(S)

Intracytoplasmic sperm injection with SSR using fresh or cryopreserved sperm and using ejaculated, testicular, and epididymal sperm.

MAIN OUTCOME MEASURE(S)

Live birth rate, pregnancy rate, and implantation rate.

RESULT(S)

We analyzed data from 214,649 ICSI cycles, including 199,818 cycles of ejaculated sperm, 5,646 cycles of epididymal sperm, and 9,185 cycles of testicular sperm. Live births rates per ICSI cycle were 28.5%, 30.6%, and 28.7% for ejaculated, epididymal, and testicular sperm cycles, respectively. Epididymal sperm cycles had a higher live birth rate than that of testicular sperm cycles (odds ratio [OR], 1.067; 95% confidence interval [CI], 1.014-1.123). This was despite a higher mean male age (42.5 vs. 40.6 years; 95% CI of difference, 1.81-1.85 years) and female age (34.3 vs. 34.0 years; 95% CI of difference, 0.32-0.34 years) in epididymal cycles than in testicular cycles. Implantation (61.2% vs. 58.0%; OR, 1.086; 95% CI, 1.041-1.133) and clinical pregnancy rates (34.3% vs. 31.3%; OR, 1.085; 95% CI, 1.039-1.132) were also higher in epididymal cycles than in testicular cycles. There were no statistically significant differences in outcomes between cycles using fresh sperm and those using cryopreserved sperm for SSR-ICSI.

CONCLUSION(S)

Our study indicates that reproductive outcomes of SSR-ICSI are at least comparable with those of ICSI using ejaculated sperm and does not support the preferential use of fresh sperm over cryopreserved sperm in SSR-ICSI. Births per SSR-ICSI cycle were higher for cycles using epididymal sperm than for cycles using testicular sperm; however, the differences were small, which may provide reassurance to patients undergoing these procedures. The results must be interpreted with caution because multivariable analysis was not possible because of aggregation of data.

Does ICSI outcome in obstructive azoospermia differ according to the origin of retrieved spermatozoa or the cause of epididymal obstruction? A comparative study

Purpose

To determine whether ICSI outcomes are affected by sperm source or genital tract inflammatory status.

Methods

A retrospective cohort study was conducted in all consecutive obstructive azoospermia patients who underwent testicular sperm aspiration (TESA) or percutaneous epididymal sperm aspiration (PESA) and ICSI between February 1, 2017, and December 31, 2020. Couples were excluded if they were diagnosed with monogenic disease, abnormal karyotype, or had female uterine malformation. The primary objective was to determine whether ICSI outcomes are affected by the use of testicular or epididymal spermatozoa, and the secondary objective was to explore the effect of granulocyte elastase on ICSI outcomes using epididymal spermatozoa.

Results

Compared with TESA, inflammatory and non-inflammatory PESA patients exhibited a better high-quality embryo rate, with significant differences among the three groups (49.43 vs. 55.39% and 56.03%; odds ratio, 6.345 and 6.631; 95% confidence interval, 0.340–12.350, and 1.712–11.550; P = 0.038 and P = 0.008, respectively). The fertilization rate, clinical pregnancy rate, live birth delivery rate, and congenital anomaly birth rate were similar in patients who underwent TESA or PESA (with or without inflammation).

Conclusions

The high-quality embryo rate in PESA patients was higher than that in TESA patients. After successful pregnancy, ICSI outcomes did not differ between patients with obstructive azoospermia who experienced TESA or PESA and those with or without genital tract inflammation.

Sperm Selection Procedures for Optimizing the Outcome of ICSI in Patients with NOA

Retrieving spermatozoa from the testicles has been a great hope for patients with non-obstructive azoospermia (NOA), but relevant methods have not yet been developed to the level necessary to provide resolutions for all cases of NOA. Although performing testicular sperm extraction under microscopic magnification has increased sperm retrieval rates, in vitro selection and processing of quality sperm plays an essential role in the success of in vitro fertilization. Moreover, sperm cryopreservation is widely used in assisted reproductive technologies, whether for therapeutic purposes or for future fertility preservation. In recent years, there have been new developments using advanced technologies to freeze and preserve even very small numbers of sperm for which conventional techniques are inadequate. The present review provides an up-to-date summary of current strategies for maximizing sperm recovery from surgically obtained testicular samples and, as an extension, optimization of in vitro sperm processing techniques in the management of NOA.

How do we counsel men with obstructive azoospermia due to CF mutations?-a review of treatment options and outcomes

Obstructive azoospermia (OA) is a rare cause of male infertility, with Congenital Bilateral Absence of The Vas Deferens (CBAVD) being a major cause. A wealth of literature has established an irrefutable link between CFTR mutations and CBAVD, with CBAVD affecting almost all men with cystic fibrosis (CF) disease and a significant portion of men that are CFTR mutation carriers. In the past two decades, assisted reproductive technologies have made the prospect of fathering children a viable possibility in this subset of men, using a combination of sperm extraction techniques and intracystoplasmic sperm injection (ICSI). In order to assess techniques for sperm retrieval, as well as reproductive outcomes, a systemic search of the MEDLINE database was conducted for all articles pertaining to management options for CBAVD, and also all reports describing outcomes of these procedures in the CBAVD population. Both epididymal and testicular sperm extraction (TESE) are viable options for men with CBAVD, and though rigorous data are lacking, live birth rates range from 8% to 50% in most small retrospective series and subset analyses. In addition, there does not appear to be significant differences in the rate of live birth or complications and miscarriages between the various techniques, though further investigation into other factors that limit reproductive potential of men with CFTR mutations and CBAVD is warranted.

Factors related to infertility in Brazil and their relationship with success rates after assisted reproduction treatment: an integrative review

This integrative review evaluated the most commonly diagnosed causes of infertility in men and women in Brazil, as well as the medically assisted reproduction technologies regularly employed in these cases. We searched in four electronic databases (PubMed, including Medline; Scopus; Web of Science and LILACS), and two grey literature (Google Scholar and OpenGrey), guided by the focused question: "What are the main factors responsible for male and female infertility in Brazil, and what are its relationships with success rates after assisted reproduction treatment?". We included interventional or observational studies, without limitation by language or year of publication. Our searches in the electronic indexers recovered 1,119 articles, and after analyzing the inclusion and exclusion criteria, 27 articles composed the body of analysis for this review. We grouped the studies into four themes: factors responsible for male and female infertility, assisted reproductive technologies (ART) used in the infertility treatment, assisted reproduction procedures, and clinical predictors of success rates in ART. Despite the scarcity of studies analyzing the association between infertility and assisted reproductive technologies in Brazil, it was possible to infer that the most prevalent infertility cause in women was endometriosis, while in men it was azoospermia. The most widely assisted reproductive technology applied in the country is the intracytoplasmic injection of spermatozoa (ICSI), ensuring better success rates in the treatment of infertility for men and women.

Effect of senescence on morphological, functional and oxidative features of fresh and cryopreserved canine sperm

The present research aimed to compare the hormonal profile, sperm quality and freezability of young and senile dogs. Dogs were assigned into Young Group (n = 11) and Senile Group (n = 11), additionally divided into Fresh Semen Group and Cryopreserved Semen Group. Males were evaluated for libido score and blood estrogen and testosterone assay. Sperm morphofunctional evaluations were performed based on Computer Assisted Sperm Analysis, morphology, mitochondrial activity, mitochondrial membrane potential, plasma and acrosomal membrane integrity, and DNA fragmentation. Sperm oxidative features were: protein oxidation, lipid peroxidation and production of advanced glycation end-products. Young dogs had higher libido score, sperm velocity average pathway, linearity of motility and mitochondrial activity index and lower percentage of major defects, total defects and proximal cytoplasmic droplet, despite the lack of difference between hormone profile of aged dogs. Fresh semen of senile dogs had increased percentage of spermatozoa with high mitochondrial membrane potential compared to young dogs and to cryopreserved sperm. Cryopreserved semen of young dogs had higher acrosomal membrane integrity compared to the Senile Group. In conclusion, sperm of aged dogs have reduced quality, signaled by higher morphological defects, ultimately altering sperm mitochondrial function and sperm kinetics. Furthermore, spermatozoa from senile dogs are more sensible to cryoinjury.

The effect of air dust pollution on semen quality and sperm parameters among infertile men in west of Iran

Background: Pollutants during haze and Asian dust storms are transported out of the Asian continent, affecting the regional climate and the hydrological and biogeochemical cycles. Nonetheless, no specific studies evaluated the dust particles influence on semen quality in a specific geographical area.Objective: In this article, we investigated the effect of dust particles on semen quality and sperm parameters among infertile men.Methods: A descriptive-analytic study was conducted among 850 infertile men between 2011 and 2015 years. Semen quality was assessed according to the WHO 2010 guidelines, including sperm concentration, progressive motility, and morphology. Four-year average dust particle concentrations were estimated at each participant's address using the Air Pollution Monitoring Station affiliated with the Department of Environment of Kermanshah city were gathered.Results: Dust particle levels were highest in the summer months, in Kermanshah province. Our results show that, dust pollution was found to be significantly negatively correlated with sperm morphology and sperm concentration before and after lab-processing, but sperm progressive motility is low sensitive to dust particles.Conclusions: Our findings showed that exposures to dust particle may influence sperm quantity in infertile men, consistent with the knowledge that sperm morphology and concentration are the most sensitive parameters of dust pollution.

Vasectomy reversal: a review on outcomes using a loupe-assisted vasovasostomy approach

INTRODUCTION

Vasectomy is a popular choice of contraception worldwide. In the UK, vasectomy reversal is not usually licensed under the NHS with reports on outcomes being limited. Microsurgical reversal is a technique commonly performed under the operating microscope. Loupe magnification, however, is emerging as a safe and reliable technique to perform microsurgery.

METHOD

Loupe-assisted microsurgical vasovasotomies were performed on 14 men in a 3-year period. Indications for the procedure were for fertility only. Semen analysis variables were measured against European Association of Urologists (EAU) guidelines at six weeks. Patients were followed-up at clinic in three months. Data were collated using operation notes and cytology results, and analysed using descriptive statistics. Pearson's correlation coefficient was used to compare years after vasectomy, and age to sperm count.

RESULTS

The average sperm count in our group was 41.3 million per millilitre (median 29.95, range 2.7-107.8) at 6 weeks. Seventy-five per cent were found to have positive sperm motility, and all had acceptable sperm morphology at follow-up. A very low to weak correlation between time after vasectomy and age, with sperm count.

CONCLUSION

We have demonstrated that fertility and post-operative outcomes using a loupe-assisted microsurgical vasovasotomy approach are favourable as per EAU guidelines.

A case of persistent haematospermia secondary to seminal vesicle calculi in an ageing male

Seminal Vesicle (SV) calculi are a rare pathology. Clinical presentation usually consists of nonspecific perineal pain and haematospermia. Adjuncts to aid diagnosis include US, MRI, and Vesiculography. This rare condition can be treated conservatively, however, surgical options are becoming more advanced with Vesiculoscopy now being the gold standard. Here, we present a case of a SV calculi treated conservatively.

Novel micro-straw for freezing small quantities of human spermatozoa

OBJECTIVE

To evaluate a novel micro-straw as an efficient, simple method for freezing a small number of human spermatozoa for intracytoplasmic sperm injection (ICSI).

DESIGN

Prospective cohort study.

SETTING

Sperm bank.

PATIENT(S)

Men with severe oligozoospermia or azoospermia undergoing a total of 143 ICSI cycles at the CITIC-Xiangya Hospital of Reproduction and Genetics from June 1, 2015, to June 31, 2019, and 20 donors at the Hunan Province Human Sperm Bank from 2001 to 2016.

INTERVENTION(S)

Analysis of sperm samples and clinical outcomes after sperm use.

MAIN OUTCOME MEASURE(S)

Clinical information, including number of motile sperm before and after freezing, freeze-thaw survival rates, two-pronuclear fertilization rates, clinical pregnancy, and early pregnancy loss rates after sperm use.

RESULT(S)

In the feasibility experiment using the micro-straw, we found a freeze-thaw survival rate of 73% ± 8.3% and no difference in normal sperm morphology, normal acrosome integrity, or DNA fragmentation index between the micro-straw and 1.8-mL cryotubes. The prospective cohort included 1,325 cases, and we collected sperm from testicular, epididymis, and ejaculation sources. We observed motile sperm in 1,294 (97.6%) of 1,325 frozen-thawed samples. Postthaw sperm were available for ICSI in 140 (97.9%) of 143 of cycles. The fertilization, cleavage, and high-quality embryo rates were 1,007 (81.7%) of 1,233; 995 (98.8%) of 1,007; and 537 (53.9%) of 995, respectively. Sixty-nine (49%) clinical pregnancies were achieved, and the miscarriage rate was 6 (8.6%) of 69.

CONCLUSION(S)

The micro-straw is suitable and clinically useful for the cryopreservation of small numbers of spermatozoa.

Testicular versus percutaneous epididymal sperm aspiration for patients with obstructive azoospermia: a systematic review and meta-analysis

Background

Intracytoplasmic sperm injection (ICSI) is a popular treatment for male infertility due to obstructive azoospermia (OA). Testicular sperm aspiration (TESA) and percutaneous epididymal sperm aspiration (PESA) are two common sperm retrieval approaches for ICSI among men with OA. However, the comparative efficacies of TESA and PESA have been debated for more than a decade and there has been no synthesis of the available evidence. This meta-analysis compared fertility outcomes between TESA and PESA among men with OA undergoing ICSI.

Methods

We searched Embase, PubMed, ScienceDirect, and Web of Science to identify studies comparing the effectiveness of TESA and PESA for ICSI. Study quality was assessed using the Newcastle-Ottawa scale. Data were pooled using a random-effects model. Outcomes were fertilization rate, implantation rate, pregnancy rate, and miscarriage rate. Results are expressed as odds ratio (OR) with 95% confidence intervals (CIs). Study heterogeneity was evaluated by the I-square (I²) statistic.

Results

Of 2,965 references retrieved, eight studies met eligibility criteria. These studies included 2,020 men receiving 2,060 ICSI cycles. The pooled results showed no significant differences in pregnancy and miscarriage rates between TESA and PESA groups, but TESA yielded a significantly higher implantation rate than PESA (OR =1.58, P=0.02, I²=24%).

Conclusions

TESA and PESA yielded similar pregnancy and miscarriage rates for couples receiving ICSI because of OA, but each demonstrated unique advantages and disadvantages. Further studies are required to evaluate safety outcomes and efficacy for specific clinical groups.

ICSI using fresh and frozen PESA-TESA spermatozoa to examine assisted reproductive outcome retrospectively

OBJECTIVE

The male reproductive system generates, accumulates, and transports the sperm. In this study, 2 methods of surgically retrieving sperm, namely, testicular sperm aspiration (TESA) and percutaneous epididymal sperm aspiration (PESA), are discussed and studied in men aged ≤38 years to achieve successful conception using assisted reproductive technology. The purpose was to assess the fertilization rate (FA), clinical pregnancy, and live birth rate (LBR) with sperm.

METHODS

A total of 287 semen samples were divided into 4 groups as follows: fresh PESA (n=73), frozen PESA (n=65), fresh TESA (n=128), and frozen TESA (n=21). The DNA fragmentation test using sperm chromatin dispersion assay was measured and reported.

RESULTS

FA was 70.3% and 65.5%, (P<0.022) for fresh and frozen epididymal sperm and 53.8% and 49.5%, (P<0.032) for fresh and frozen testicular sperm. LBR was 33.6% and 30.2% (P<0.075) for fresh and frozen epididymal sperm (PESA) and 22.7% and 18.2% (P<0.063) for fresh and frozen-thawed TESA sperm.

CONCLUSION

Exposure to tissue shearing may adversely affect sperm quality. Increased sperm DNA damage due to long-term exposure while teasing enhances reactive oxygen species production foremost to membrane damage because of the oxidation of polyunsaturated fatty acid in lipids (lipid peroxidation), oxidation of amino acid in proteins, and inactivation of specific enzymes, all leading to enzymatic dipping and possibility of less fertilization and conception as indicated by the increase in LBR with fresh/frozen PESA compared to with fresh/frozen TESA.

Testicular Fine-Needle Aspiration for Sperm Retrieval in Azoospermia: A Small Step toward the Technical Standardization

PURPOSE

The aim was to describe our preliminary experience performing testicular fine-needle aspiration (TEFNA) with a larger needle in infertile patients with obstructive azoospermia, and to provide a systematic literature review of the different testicular sperm aspiration techniques, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement recommendations.

MATERIALS AND METHODS

We prospectively collected data between March 2017 and June 2018. All men underwent bilateral TEFNA under analgo-sedation, using a larger disposable 18-gauge butterfly needle with 60 mL Luer-Lock syringe attached to it.

RESULTS

Thirty consecutive patients were enrolled. Median operative time was 16 minutes (interquartile range [IQR]: 12-30 minutes). No intraoperative complications occurred. Two/thirty patients (6.7%) reported postoperative adverse events: 1 patient had prolonged orchialgia, 1 patient presented scrotal hematoma. Successful sperm retrieval was found in 28/30 cases (93.3%). Median sperm concentration was 0.05 ×10⁶/mL (IQR: 0.001-0.1 ×10⁶/mL). Median total sperm motility was 10% (IQR: 0%-15%). In 20/30 men (66.7%) sperm retrieved was used for fresh intracytoplasmic sperm injection cycle, in 8/30 (26.7%) sperm cryopreservation was necessary, because on the day of sperm retrieval the female resulted not responder to ovarian stimulation. In this cases mean number of 3 (IQR: 1-4) bio system straws was cryopreserved.

CONCLUSIONS

TEFNA with 18-gauge needle proved to be a feasible, safe and effective treatment, even if future prospective studies will be addressed to clarify what type of azoospermia benefits from this procedure, and if a larger needle permits to improve Assisted Reproductive Technologies (ART) outcomes.

Localization of the SRY Gene on Chromosome 3 in a Patient with Azoospermia and a Complex Karyotype 45,X/46,X,i(Y)(q10)/46,XX/ 47,XX,i(Y)(q10)

This study aimed to identify the cause of azoospermia in a 38-year-old infertile man who was referred for genetic testing. Cytogenetic evaluation was performed by G-banding, C-banding, and FISH using centromeric probes for chromosomes X and Y and showed the presence of a monocentric isochromosome Y with a complex, mosaic karyotype 45,X/46,X,i(Y)(q10)/46,XX/47,XX,i(Y)(q10). Multiplex PCR for the commonly deleted genes in the AZFa, AZFb, and AZFc regions of the Y chromosome was performed and indicated the presence of all 3 regions. Further, PCR amplification followed by DNA sequencing of the SRY gene was done, which ruled out mutations in that gene. To identify the position of the SRY gene, FISH using a locus-specific probe was used and showed that the gene had been translocated to chromosome 3. Subtelomere FISH for 3q and Yp evidenced that the subtelomeric region of the Y chromosome was found on the terminal region of 3q. The clinical symptoms of the patient can be attributed to this abnormal genotype. The importance of genetic testing in infertile patients and the need for genetic counselling to prevent the transmission of the defect are emphasized.

Sperm retrieval and quality evaluation

Technical refinements in sperm retrieval methods and the application of advanced reproductive technologies (ART) using surgically retrieved sperm have enabled biological paternity in azoospermic men who were considered untreatable 20 years ago. Achievement of optimal reproductive outcomes in these patients benefits greatly from a multistep, interdisciplinary process of sperm acquisition that involves reproductive endocrinologists, urologists, or other specialists in male subfertility, and laboratory personnel with expertise in characterizing and isolating sperm from surgically retrieved specimens. The critical steps in this process are discussed in this chapter.

Reproductive outcomes, including neonatal data, following sperm injection in men with obstructive and nonobstructive azoospermia: case series and systematic review

We compared pregnancy outcomes following intracytoplasmic sperm injection for the treatment of male infertility according to the type of azoospermia. First, we analyzed our data from 370 couples who underwent intracytoplasmic sperm injection using sperm from men with obstructive azoospermia and nonobstructive azoospermia, and the outcomes were compared to a group of 465 non-azoospermic infertile males. Then, we performed a systematic review of the published data on pregnancy and neonatal outcomes of children born after sperm injection using sperm from men with obstructive and nonobstructive azoospermia. Live birth rates were significantly lower in the nonobstructive azoospermia group (21.4%) compared with the obstructive azoospermia (37.5%) and ejaculated sperm (32.3%) groups. A total of 326 live births resulted in 427 babies born. Differences were not observed between the groups in gestational age, preterm birth, birth weight and low birth weight, although we noted a tendency towards poorer neonatal outcomes in the azoospermia categories. The overall perinatal death and malformation rates were 2.8% and 1.6%, respectively, and the results did not differ between the groups. We identified 20 published studies that directly compared pregnancy outcomes between obstructive azoospermia and nonobstructive azoospermia. Most of these studies were not designed to detect differences in live birth rates and had lower power to detect differences in less frequent outcomes, and the reporting of neonatal outcomes was unusual. The included studies reported either a decrease or no difference in pregnancy outcomes with intracytoplasmic sperm injection in cases of nonobstructive azoospermia and obstructive azoospermia. In general, no major differences were noted in short-term neonatal outcomes and congenital malformation rates between children from fathers with nonobstructive azoospermia and obstructive azoospermia.

A comprehensive review of genetics and genetic testing in azoospermia

Azoospermia due to obstructive and non-obstructive mechanisms is a common manifestation of male infertility accounting for 10-15% of such cases. Known genetic factors are responsible for approximately 1/3 of cases of azoospermia. Nonetheless, at least 40% of cases are currently categorized as idiopathic and may be linked to unknown genetic abnormalities. It is recommended that various genetic screening tests are performed in azoospermic men, given that their results may play vital role in not only identifying the etiology but also in preventing the iatrogenic transmission of genetic defects to offspring via advanced assisted conception techniques. In the present review, we examine the current genetic information associated with azoospermia based on results from search engines, such as PUBMED, OVID, SCIENCE DIRECT and SCOPUS. We also present a critical appraisal of use of genetic testing in this subset of infertile patients.

[Assisted reproductive technologies place]

There are three kinds of infertility treatment: medical treatment, surgical treatment and assisted reproductive technology (ART). ART includes intra uterine insemination (IUI), in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). ART technologies made a lot of progress last years and their field of applications extended. Through literature reviews, IUI is recommended for unexplained infertility and discussed for male or cervical infertility. IVF is recommended for tubal and unexplained infertility. Limits between IVF and ICSI in case of male infertility remains unclear. In non mal infertility ICSI is not recommended.
