Five years experiences with microinjection of testicular spermatozoa into oocytes in Hungary

The aim of the study was to summarize our five years experience (1996-2000) of testicular spermatozoa for intracytoplasmic sperm injection in Hungary. The influence of sperm count, maternal age, number of transferred embryos, and application of assisted hatching on outcome was investigated. Testicular spermatozoa were retrieved by microsurgical testicular sperm extraction. Samples were classified depending on the number of spermatozoa. Indication for testicular sperm extraction in conjunction with intracytoplasmic sperm injection was severe azoospermia or azoospermia combined with tubal origin infertility. Ovarian stimulation was carried out using an ultrashort protocol with GnRH agonist and gonadotrophin. Intracytoplasmic sperm injection was performed without PVP. Embryos were cultured for 48 or 72 h before embryo transfer. Indications for assisted hatching included elevated maternal age, increased zona thickness or at least two previous unsuccessful IVF cycles. Testicular spermatozoa were successfully retrieved in 218 out of 273 cases. Extreme low sperm count was found more frequently in cases of nonobstructive azoospermia. No significant differences were observed in fertilization rate (61.1% vs. 51.7%) or clinical pregnancy rate (29.0% vs. 26.7%) between patients with obstructive or nonobstructive azoospermia. Maternal age, number of transferred embryos and application of assisted hatching had a significant effect on outcome. A total of 55 clinical pregnancies were achieved, including 14 sets of twins, three sets of triplets and two sets of quadruplets. It is concluded that testicular sperm extraction is an efficient way of obtaining testicular spermatozoa, allowing not only successful fertilization by ICSI, but also freezing of testicular spermatozoa for use in subsequent cycles.     

短时受精结合早期补救ICSI技术的临床应用

常规授精中受精失败已成为辅助生殖技术面临的严峻问题,目前常用的补救措施有Half-ICSI和短时受精结合早期补救ICSI。短时受精结合早期补救ICSI技术在挽救IVF受精失败周期中有很多优势,已经被很多生殖中心所采用。但是关于短时受精对胚胎发育及临床妊娠率的影响仍存在很多争议,此外早期补救ICSI的有效性也是制约该技术应用的一个障碍。本文综述了短时受精结合早期补救ICSI技术的进展以及影响其成功率的因素,希望为该技术的临床应用提供参考。     

The effects of female age on the outcome of testicular sperm extraction and intracytoplasmic sperm injection in infertile patient with azoospermia

Introduction: 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.Materials and methods: 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.Results: 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 had significantly higher pregnancy rates than women over 34 years of age (p < 0.05).Conclusion: The female age is a major factor in determining successful implantation in ICSI.     

Influence of motility and vitality in intracytoplasmic sperm injection with ejaculated and testicular sperm

The vitality of spermatozoa used for intracytoplasmic sperm injection (ICSI) is a crucial factor for fertilization, establishment and outcome of a pregnancy in assisted reproductive technique cycles. The sperm origin may also be a limiting factor, although little is known about this issue. It is known that the motility of injected spermatozoa and their origin from ejaculate or testicular biopsies are important predictors in terms of fertilization, pregnancy and birth rates. Oocytes of patients in 2593 cycles were retrieved in our in vitro fertilization programme and inseminated via ICSI. We used motile (group 1, n = 2317) or immotile ejaculated spermatozoa (group 2, n = 79), motile sperm retrieved from testicular biopsies (group 3, n = 62) and immotile spermatozoa from testicular biopsies (group 4, n = 135). Female age and number of oocytes retrieved did not differ significantly among the groups. The fertilization rates were as follows: 67.1% in group 1, 49.8% in group 2, 68.3% in group 3 and 47.8% in group 4. The pregnancy rates in cases where three embryos had been transferred amounted to 35.7% in group 1, 17.3% in group 2, 38.3% in group 3 and 20.5% in group 4. The embryo quality showed no differences between groups 1 and 3 (14.5), and between groups 2 (11.8) and 4 (10.8). The abortion rate was similar in groups 1-3, but increased in group 4 (26.6%, 27.3%, 31.6% and 55.5%). Irrespective of their origin, the fertilization potential of injected spermatozoa was found to be influenced by motility. The resulting pregnancy and birth rates, i.e. the potential of the resulting embryos to implant and to achieve viable pregnancies, seem to be additionally dependent on the sperm origin. This was well shown by declining rates when spermatozoa in a relatively early stage of maturity had been used. We see increasing evidence that the degree of sperm maturity has an important impact on the outcome of ICSI. In obstructive azoospermia, spermatozoa retrieved from the epididymis should be used rather than testicular biopsy spermatozoa, or testicular sperm should be preincubated in culture medium before ICSI.
