PURPOSE OF REVIEW: The purpose of this review is to analyze what is known to date about the relation between telomeres and male fertility, and if it is possible for telomeres, or elements related to them, to be used as new prognostic biomarkers in fertility treatment. RECENT FINDINGS: Cells in germ series, including spermatozoids, have longer telomeres (10-20 kb), and do not seem to undergo the shortening that takes place in somatic cells with age as they present telomerase activity...

Assisted reproductive techniques have been used on several domestic animals to preserve desirable traits in strains of high genetic and commercial value; however in equines its efficiency rate is relatively low. To increase the conception ratio in stallions, some research groups have used pharmacological treatments which promote sperm hyperactivation in order to increase male's fertility rates. In this way, our previous work suggests that serotonin (5-HT) could be a good pharmacological candidate that facilitates conception rate in domestic horses...

Assisted reproduction techniques (ART) have significantly advanced since the first successful in vitro fertilization (IVF). However, most in vitro-produced embryos fail to implant. Key steps in ART are the correct infertility diagnosis, in order to manage the individual treatments, and the assessment of gamete and embryo viability, to identify the embryo with the best implantation potential. Non-invasive approaches to correctly diagnose infertility and to access embryo development potential have the advantages of increasing the knowledge of embryo physiology, therefore allowing the development of methods to predict developmental competence and viability...

Protamines are the most abundant sperm nuclear proteins and pack approximately the 92-98% of the mammalian sperm DNA. In mammals, two types of protamines have been described, the protamine 1 (P1) and the protamine 2 (P2) family, whose relative ratio has been related to the proper sperm chromatin maturity and the normality/abnormality of the male gamete. Specifically, the deregulation of the P1/P2 ratio has been correlated to DNA damage, alterations in seminal parameters, and low success rate of assisted reproduction techniques...

Fertilization problems are the major problems that may be faced in 30-55% of the patients during an intracytoplasmic sperm injection (ICSI) cycle. A successful oocyte activation depends on factors related to both sperm and oocyte, and one of the important factors that mediates the process is Ca2+ concentration within the oocyte. Artificial oocyte activation (AOA) is a method used for fertilization problems that commonly involve the usage of Ca2+ ionophores and is usually used in problems such as total fertilization failure (TFF) and globozoospermia...

MicroRNAs (miRNAs) are a novel class of small noncoding RNAs (ncRNAs) that play critical roles in regulation of gene expression, especially at posttranscriptional level. Over the past decade, the degree to which miRNAs are involved in male infertility has become clear. They are expressed in a cell- or phase-specific manner during spermatogenesis and play crucial role in male reproductive health. Therefore, dysregulation of miRNAs in testicular cells can be considered as a molecular basis for reproductive failure and male infertility...

In vitro maturation (IVM), the maturation in culture of immature oocytes, has been used in clinic for more than 20 years. Although IVM has the specific advantages of low cost and minor side effects over controlled ovarian stimulation, the prevalence of IVM is less than 1% of routine in vitro fertilization and embryo transfer techniques in many reproductive centers. In this review, we searched the MEDLINE database for all full texts and/or abstract articles published in English with content related to oocyte IVM mainly between 2000 and 2016...

Selection of functional spermatozoa plays a crucial role in assisted reproduction. Passage of spermatozoa through the female reproductive tract requires progressive motility to locate the oocyte. This preferential ability to reach the fertilization site confers fertility advantage to spermatozoa. Current routine sperm selection techniques are inadequate and fail to provide conclusive evidence on the sperm characteristics that may affect fertilization. We therefore developed a selection strategy for functional and progressively motile bovine spermatozoa with high DNA integrity based on the ability to cross laminar flow streamlines in a diffuser-type microfluidic sperm sorter (DMSS)...

Embryo cryopreservation is important for long-term preservation of germplasm and assisted reproduction. However, it is still very difficult to obtain viable embryos from cryopreserved fish embryos. In this study, embryos of Epinephelus moara were used to investigate the effects of various cryopreservation methods. Embryos in stages 10 pairs somite (10S), 18 pairs somite (18S), 22 pairs somite (22S), tail-bud (TB), embryo twitching (ET) and pre-hatch (PH) were treated with five-step equilibrium penetration in 40% PMG3T vitrification solution, which contained 15...

This article is a personal perspective on male infertility, a condition that is not only extremely prevalent but also a major reason for couples to resort to assisted reproductive technology. The introduction of intra-cytoplasmic sperm injection (ICSI) as a form of facilitated fertilization had a revolutionary impact on our capacity to treat cases of male infertility associated with severely-compromised semen quality. However, the widespread use of this technique is also thought to pose risks in terms of the incidence of miscarriage, the health and wellbeing of the offspring and perpetuation of the infertile phenotype into future generations...
