ABSTRACT

BACKGROUND AND AIMS: Motility and morphological defects of spermatozoa can cause male infertility. Sperm RNAs are related to sperm quality. They are considered to have clinical values as a biomarker for assessing sperm quality and fertility potential. The annulus, located in the mammalian sperm tail, is required for motility and terminal differentiation of the spermatozoa. SEPT2, 4, 6, 7, and 12 proteins are the main components of the annulus in the sperm tail. The study aimed to evaluate SEPT2 and SEPT4 mRNA contents in the spermatozoa of patients with asthenozoospermia and teratozoospermia. METHODS: We evaluated transcript levels of SEPT2 and SEPT4 in the sperm samples of 20 asthenozoospermic, 20 teratozoospermic, and 20 normozoospermic samples using quantitative PCR. RESULTS: The SEPT2 transcript level was significantly decreased in the asthenozoospermia samples compared with the normal group (P = .013). However, SEPT4 was not significantly different between these two groups. The transcript levels of SEPT2 and SEPT4 were not statistically different between teratozoospermic and normozoospermic groups. CONCLUSION: In conclusion, downregulation of SEPT2 in patients with asthenozoospermia appears to be associated with poor sperm motility.

ABSTRACT

Investigation of the cryo-injury mechanism can provide novel insight into cryopreservation. The objective of this study is to assess the effect of cryopreservation on fertility potential, motility, oxidative stress (OS), DNA fragmentation, microRNAs (miRNAs), and apoptotic target genes in the infertile men compared to the fertile men. All 40 samples were divided into two leading groups of fresh and cryopreserved sperms. Each main group was subdivided into three groups including, Normozoospermia, and Mild, and Severe Oligoasthenoteratozoospermia (OAT). In all collected samples the following were assessed: microRNA-34c (miR-34c) and miR-184, P53 and Caspase9 using Quantitative real-time polymerase chain reaction (RT-PCR), malondialdehyde (MDA), Superoxide dismutase (SOD) using imaging multi-mode reader, and DNA fragmentation using Sperm DNA Fragmentation Assay Test (SDFA). Within the studied groups, immotile spermatozoa were increased due to cryopreservation. We observed an increasing levels of SOD, MDA, and DNA fragmentation. Also, cryopreservation was associated with decreasing the expression of P53, mir-43c, and miR-184 while capase9 was showed enhancing expression after freeze-thawing of sperm cells. During cryopreservation, sperm fertility and motility were influenced via apoptosis cascade-mediated mitochondrial dysfunctions such as caspase9. Also, we found that miR-34c, miR184, and P53 could impact fertility potential. In Addition, there was a meaningful correlations between microRNAs and motility post freeze-thawing process in Severe Oligoasthenoteratozoospermia men.

ABSTRACT

BACKGROUND: Oral progesterone is recommended as an alternative to gonadotropin-releasing hormone (GnRH) agonists and antagonists to prevent luteinizing hormone (LH) surge in assisted reproductive technology (ART) cycles. However, there are little data regarding its use. OBJECTIVE: We aimed to compare the effect of oral Utrogestan and Cetrotide (a GnRH antagonist) on preventing LH surge in ART cycles. MATERIALS AND METHODS: In this randomized clinical trial, 100 infertile women undergoing ART who received recombinant follicle-stimulating hormone (FSH) at 150-225 IU/day were randomly assigned to receive either Utrogestan 100 mg twice a day (case group) or GnRH antagonist protocol (control group) from cycle day 3 until the trigger day. Triggering was performed with 10,000 IU hCG) when there were at least three mature follicles. Viable embryos were cryopreserved for transfer in the next cycle for both groups. The number of oocytes retrieved and transferred embryos were compared between groups. RESULTS: The case group had significantly higher progesterone levels on triggering day, more follicles of > 14 mm with higher maturity, and more oocytes retrieved with a higher rate of embryos transferred. A small increase in the pregnancy rate was observed in the case group, with no significant between-group differences. The most important result was the lack of premature LH surge in either group upon serum LH assessment on the triggering day. CONCLUSION: Utrogestan is an alternative treatment that could reduce the LH surge rate and increase the ART outcomes including the number of oocytes retrieved and transferred embryos compared with GnRH agonists and antagonists.
