Evaluation of sperm telomere length in infertile men with failed/low fertilization after intracytoplasmic sperm injection

This study therefore aimed to assess sperm telomere length in addition to DNA damage, lipid peroxidation and protamine deficiency in infertile men with previously failed/low fertilization post-ICSI.DesignSemen samples were obtained from infertile men with previous failed/low fertilization rates (n = 10). Chromatin integrity (chromomycin A3 staining and TUNEL assay), lipid peroxidation (BODIPY probe) and telomere length (real-time PCR) for semen samples from these men were compared with samples obtained from fertile individuals (n= 10).ResultsThe results showed significantly higher mean values for sperm DNA damage, lipid peroxidation and reduced telomere length in spermatozoa of infertile men with previous failed/low fertilization compared with fertile individuals (P

Conclusion: Our results indicated that GnRH agonist pre-treatment before starting the long GnRH agonist protocol does not improve the live birth rate in fresh embryo transfer cycles or CLBR in infertile women with adenomyosis after IVF/ICSI treatment when compared to that in non-pre-treated patients. A subsequent prospective randomized controlled study is needed to confirm these results.

The objective of this study was to examine the effectiveness and safety of ovarian stimulation (OS) with follitropin alfa (Ovaleap®) for routine IVF or intracytoplasmic sperm injection treatment in gonadotropin-releasing hormone (GnRH) antagonist cycles in real-world ART clinical practice. METHODS: This non-interventional, multicenter, prospective study was initiated in 34 specialized reproductive medicine centers in Germany. Eligible women were 18-40 years old with a body mass index

This study aimed to investigate the effect of the detail type of chromosomal polymorphisms (1/9/16qh+/ −, D/G group polymorphisms, and inv(9)) on the IVF-ET outcomes.MethodsA total of 1335 infertile couples undergoing IVF/ICSI were enrolled and comprehensively analyzed the correlation between three detail types of chromosomal polymorphisms (1/9/16qh+/ −, D/G group polymorphisms, and inv(9)) and the outcome of IVF/ICSI embryo transfer. The fertilized rate, cleaved embryo rate, good-quality embryo rate, clinical pregnancy rate, implantation rate, and early stage miscarriage rate were compared between the chromoso...

ConclusionThis study concurs with the recent data suggesting that employing ICSI solely for teratospermia is unnecessary. This may allow clinics to decrease ICSI rates without sacrificing success rates, leading to lower cost and risk associated with treatment.

We report the following outcomes: (1) live birth rates in AID and IVF-D treatment for couples with severe male infertility factors and prior ICSI failures; (2) paternal impact on embryo development of the same oocyte cohort; (3) prognostic factors in obtaining a live birth with donor semen.ResultsOf 92 women with failed ICSI cycles (26 with multiple attempts), 45 couples underwent AID treatment. Live birth rate per cycle of AID was 18.9%. Fifty-three patients underwent IVF-D including 6 couples who previously did not conceive with AID. Embryological outcomes including fertilization, viable cleavage embryos, and blastocyst ...

ConclusionOverall, this study offers new insight on AMH effects upon cumulus cells and new aspects on how AMH might promote oocyte integrity and embryo viability at a biochemical level as well as add to the current body of evidence supporting AMH clinical potential as a more sensitive marker ofIVF outcomes in comparison with FSH, regarding numbers of oocytes received and high-quality day 2 and day 3 embryos.

This study aimed to explore the association of serum 25 ‐hydroxyvitamin D (25OHD) levels and semen parameters, as well as ART outcomes for men from infertile couples.Materials and MethodsThis study recruited 1,308 men from infertile couples who attended the Reproductive Medicine Center of Peking University Third Hospital for first time from February to August 2019(NCT03804294). Reproductive hormones levels, semen parameters and clinical outcomes of ART were compared between vitamin D deficient group (serum 25OHD ≤10 ng/mL), insufficient group (serum 25OHD 10‐20 ng/mL) and sufficient group (serum 25OHD≥20 ng/mL).R...

ConclusionsThe study highlights the importance of sperm quality for the efficacy of assisted reproduction treatments. This influence may remain relatively cryptic in association with normal or high ovarian response, but emerge decisively in cases of reduced ovarian response, suggesting a relationship between ovarian response and oocyte ability to compensate for paternal-derived deficiencies.
