Intracytoplasmic sperm injection with testicular spermatozoa in men with azoospermia
Journal of assisted reproduction and genetics, 2002
The aim of the study was to gain an insight into the optimal management of the infertile couple with the husband suffering from azoospermia. One hundred and forty-two intracytoplasmic sperm injection (ICSI) cycles performed with testicular extracted spermatozoa were retrospectively analysed. The following factors were investigated for their possible influence on fertilization, cleavage, damage, pregnancy, and ongoing pregnancy rates: the use of fresh, cryopreserved, and preincubated (24 h) spermatozoa and the etiology of the husbands' azoospermia (obstructive and nonobstructive). All microinjections were performed with apparently normal spermatozoa--a head with a tail of normal length. In 116 cycles at least two embryos were available for transfer. The overall fertilization, clinical pregnancy, and ongoing pregnancy rates obtained for the 116 cycles were 65.0, 30.2, and 22.4% respectively. Similar outcomes were obtained for cycles using fresh testicular and cryopreserved testicu...

To analyze the outcome of intracytoplasmic sperm injection (ICSI) cycles in infertile couples in whom the main diagnosis of infertility was azoospermia of obstructive and nonobstructive origin. Eighty-three consecutive ICSI cycles were carried out with retrieved testicular or epididymal spermatozoa, 60 cycles in 32 patients with obstructive azoospermia and 23 cycles in 12 patients with nonobstructive azoospermia. Fifty-four testicular biopsies (testicular sperm extraction) and 18 epididymal aspirations (microepididymal sperm aspiration) were performed.Results. Motile spermatozoa were recovered in 65 cycles (90.3%). In another 3 (4.2%), nonmotile spermatozoa were retrieved. In 4 patients (5.5%), sperm could not be recovered. In 11 cycles, frozen sperm from a previous procedure were used. A significantly lower fertilization rate (64% versus 73%, P = 0.02), clinical pregnancy rate (13% versus 47%, P <0.001), and good embryo quality rates (35% versus 56%, P = 0.009) were observed in patients with nonobstructive azoospermia. In patients with obstructive azoospermia, no significant differences were observed when the outcome was analyzed on the basis of the sperm origin (ie, from testicular sperm extraction or microepididymal sperm aspiration). When combining testicular sperm extraction or microepididymal sperm aspiration with ICSI in patients with obstructive azoospermia, the results in terms of fertilization, implantation, and pregnancy rates were similar to those found in patients with nonazoospermic obstruction who underwent ICSI with ejaculated sperm. Patients with nonobstructive azoospermia had lower fertilization, embryo quality, and pregnancy rates than did those with obstructive azoospermia, probably because of severe defects in spermatogenesis, leading to poor gamete quality. The urologist and reproductive endocrinologist now have an excellent therapeutic option to offer men with previously intractable infertility.
Differential Diagnosis of Azoospermia in Men with Infertility
Journal of Clinical Medicine
The differential diagnosis between obstructive and nonobstructive azoospermia is the first step in the clinical management of azoospermic patients with infertility. It includes a detailed medical history and physical examination, semen analysis, hormonal assessment, genetic tests, and imaging studies. A testicular biopsy is reserved for the cases of doubt, mainly in patients whose history, physical examination, and endocrine analysis are inconclusive. The latter should be combined with sperm extraction for possible sperm cryopreservation. We present a detailed analysis on how to make the azoospermia differential diagnosis and discuss three clinical cases where the differential diagnosis was challenging. A coordinated effort involving reproductive urologists/andrologists, geneticists, pathologists, and embryologists will offer the best diagnostic path for men with azoospermia.

To investigate the outcome of intracytoplasmic sperm injection with fresh and cryopreserved-thawed testicular spermatozoa in the first cycle in patients with obstructive azoospermia (OA) and non-obstructive azoospermia (NOA), a total of 90 cases, 48 OA and 42 NOA were studied. All patients underwent sperm retrieval by testicular sperm extraction (TESE) while their wives received conventional ovarian hyperstimulation. The hormone levels, testicular histology, the rates of sperm retrieval, fertilization, implantation and pregnancy were analysed and evaluated. This study and other four similar studies were subjected to meta-analysis. Sperm retrieval was successful in 100% OA and 61% NOA. Fresh spermatozoa were used in 87.5% and 92.4% of OA and NOA cases respectively; while cryopreserved-thawed spermatozoa were used in 12.5% and 7.6% of OA and NOA, respectively. The fertilization, implantation and clinical pregnancy rates were 65.5%, 15% and 25% respectively in OA group, and 54.2%, 5% and 23.1% respectively in NOA group. Sperm status (fresh or thawed), male partner's age, female age and male serum folliclestimulating hormone had no significant effect upon fertilization rate, implantation rate, or pregnancy rate per embryo transfer. The results of meta-analysis indicate that there is no statistically significant difference in clinical pregnancy rates between the two groups. There was a significantly higher fertilization rate among OA patients in all analysed studies d.f. 832, T ¼ 1.96). In conclusion, although the fertilization rate was significantly higher in the OA group in our study and from the given metaanalysis, there were some differences as regards pregnancy rates. Although the overall effect was more or less similar pregnancy rates in both subtypes of azoospermia, this may not be true if non-male infertility variables were controlled for in all studies.

Background: Azoospermia is a highly upcoming subject in the last few decades. In the past, use of donor sperm was the only option providing a realistic chance of conception for couples affected by azoospermia. Introduction of sperm retrieval techniques and assisted reproductive technologies, especially intracytoplasmic sperm injection (ICSI), has provided these men a chance to father their genetically own child and changed the management approach significantly. The aim of this study was to compare the outcome of intracytoplasmic sperm injection (ICSI) of surgically retrieve sperms between couples with infertility due to male non-obstructive azoospermia (NOA) and obstructive azoospermia (OA). Methods: It was a retrospective observational study and data analysis was conducted at Centre for Infertility and Assisted Reproduction (CIMAR), Edappal, Kerala, India from January 2018 to December 2021. The selection of cases was based on detailed history, physical examination, husband's semen analysis confirmed twice and hormone profile. During a period of four years, 754 azoospermic patients were diagnosed at our centre. In this study, female age <35 years considered as the inclusion criteria as female age plays a pivotal role for IVF/ICSI outcome, while patient in whom voluntary donor sperm used, patients in whom sperm retrieval failed, female age >35 years and female associated with any pathology which can alter the treatment outcome e.g., endometriosis, severe adenomyosis, diminished ovarian reserve, fibroid uterus were excluded from the study groups. On the basis of serum FSH, serum testosterone and testicular size and considering inclusion and exclusion criteria, patients were subdivided into two group as: group A (n=75) included patients with non-obstructive azoospermia and group B (n=75) included patients with obstructive azoospermia, underwent ICSI. Results: Clinical pregnancy rate, fertilization and implantation rate were found to be higher in OA cases in comparison to those of NOA cases. Grade A embryo formation rate and miscarriage rate showed no significant difference. Conclusions: As the cause of azoospermia is different in both the groups, the chances of achieving a successful outcome (fertilization rate, embryo formation rate, and clinical pregnancy rate) after ICSI are negatively affected by the type of azoospermia and are reduced in men with NOA in comparison to patients with OA.

Objective: The absence of any sperm in the ejaculate is called azoospermia and it is detected in 1% of males and 10-15% of those with infertility complaints. Azoospermia may be due to obstructive (OA) and non-obstructive (NOA) causes. Today, healthy pregnancies can be achieved in azoospermic patients by intracytoplasmic sperm injection (ICSI) performed using sperm retrieved from microscopic testicular sperm extraction (m-TESE). In this study, we examined the sperm retrieval rates with m-TESE in azoospermic patients, the results of ICSI in OA and NOA patients with sperm and the underlying testicular pathologies in patients without sperm. Material and methods: Patients who underwent m-TESE at IVF unit of our hospital between January 2005 and April 2017 were retrospectively reviewed. A total of 342 azoospermic patients (117 OA and 225 NOA cases) with regular follow-up were included in the study. In these cases, sperm retrieval and clinical pregnancy rates after ICSI were compared. Results: In the m-TESE procedure, motile sperm was found in all of the OA patients and in 52.4% (118/225) of the NOA patients. Clinical pregnancy rate in the OA group was 29.9% (35/117) and live birth rate was 25.6% (30/117). In the NOA group, the clinical pregnancy rate was 27.1% (32/118) and the live birth rate was 23.7% (27/118). Histopathologic evaluation was made in 107 cases in the NOA group with no testicular sperm, revealing that 59 cases with germ-cell aplasia (sertoli-cell only syndrome), 42 cases with maturation arrest, and 6 cases with hypospermatogenesis. Postoperative hematoma developed in 3 of m-TESE cases and subsided with conservative treatment. Conclusion: If motile sperm is retrieved with m-TESE application in azoospermic patients, pregnancy resulting in one live birth in about 4 couples who undergo ICSI application can be achieved. In the presence of motile sperm, live birth rates are similar between OA and NOA case with very low complication rates.
Epidemiological and Clinical Profile in an Azoospermic Male-A Tertiary Care Experience
Journal of Medical Science And Clinical Research, 2017
Azoospermia is defined as the complete absence of spermatozoa upon examination of the semen. Azoospermia is present in approximately 1% of all men, and in approximately 10-20% of infertile men. Male infertility due to azoospermia is on the increase. Semen parameters are on the decline over the years. What contributes whether environmental factors changing life style and psychological stress etc. is not known? Population) suffer from. A detailed history, a physical examination, a hormone profile, imaging and genetic counseling are important to determine the specific clinical classification of the azoospermia. This study was designed to find out the epidimeological and clinical profile of azoospermic males attending our clinic. Objectives: To describe the out the epidemiological and clinical profile of azoospermic males attending fertility clinic of Sree Avitom Thirunal Hospital, Trivandrum. Materials and Methods: 100 couples with diagnosed case of azoospermia (standard protocols) registered in Fertility Clinic, SAT, Govt Medical College Thiruvananthapuram from the year 2013 was called in for a personnel interview and examination. Written consent was obtained and couples were recruited Interview method using structured closed end questionnaire Results: Out of 100 Azoospermia cases majority of patients had Primary infertility. Majority of cases of belonged to the age group between 30 to 40 and had Higher Secondary education Majority of study group belong to unskilled labour and belonged to the below poverty line population.80% of couples had a normal sexual life without any major physical or psychological sexual problems Majority had a BMI of more than 24 and 15% of patients lacked male pattern of hair distribution which was again s/o hormonal imbalance or testosterone deficiency.75% of the group had one or other substance abuse which can impair spermatogenesis-smoking and alcohol being the major culprits. Chemical exposure was seen in 11 patients.

Testicular sperm extraction (TESE) is well-defined procedure for surgical sperm retrieval in obstructive and non-obstructive azoospermia. This study was focused on the effectiveness of testicular sperm extraction and intracytoplasmic sperm injection (ICSI) for azoospermic men with different female age subgroups. A total of 107 men with azoospermia underwent TESE and ICSI treatment. The women were examined in three groups 20-29, 30-34 and 35 years or older. The main outcome in this study was fertilization and pregnancy rates with TESE and ICSI. Spermatozoa were successfully retrieved during 97 of 107 (90.7%) TESE attempts, resulting in the fertilization of 286 of 563 (50.4%) injected metaphase II oocytes. Two hundred and fifty-five of them were transferred (89.8%). The clinical pregnancy rate and ongoing pregnancy rate per embryo transfer were 22.5% and 20.6% respectively. When comparing the fertilization and pregnancy rates, it was observed that women between the ages of 20-29 years...
