AbstractThe evaluation of the seminal plasma plays a relevant role in the definition of male infertility and in assisted reproduction outcomes; for this reason, it would be recommended to find biochemical markers able to characterize sperm pathology. In this study, 53 infertile patients (grouped by the presence leukocytospermia, idiopathic infertility, or varicocele) and 10 fertile men were selected. Spermiogram was performed by light microscopy, and sperm ultrastructure was evaluated by transmission electron microscopy (TEM) mathematically elaborated. Testosterone (TESTO), estradiol (E2), ferritin (FERR), iron (Fe), transferrin (TRSF), triglycerides (TRG), cholesterol (CHOL), and isoprostanes (F2-IsoPs) were detected in seminal plasma. Sperm characteristics and biochemical components were correlated by Spearman’s rank correlation coefficient in the whole population and in each group. The levels of TESTO and E2 were positively correlated with sperm quality in particular, and E2 was correlated with fertility index expressing the number of sperm free of ultrastructural defects evaluated by TEM. On the contrary, the indices of iron metabolism (FERR, Fe, and TRSF) were positively associated with low sperm quality and sperm necrosis, particularly in leukocytospermia and varicocele groups, pathologies in which an inflammatory status and oxidative stress condition are present. The study of the seminal plasma composition deserves attention because the levels of the various components seem to be associated with specific reproductive pathologies.

ABSTRACT Background Wide variation in fertility rates is observed when using frozen bull semen, even when the bulls have met quality standards for semen production. Therefore, a simple and reliable test to assess the freezing potential of bull semen based on the analysis of fresh semen or blood would be of great value. Attention is now turning to assessment of seminal plasma components such as proteins and elements. In the present study, the concentrations of macro- and microelements in fresh bull semen plasma and in serum and their correlation with quality characteristics of fresh semen and with semen quality after freezing and thawing were determined. Ejaculates were collected from 30 mature bulls, and semen volume, concentration, sperm motility, morphology, tail membrane integrity, plasma membrane permeability and DNA fragmentation were determined on the day of collection and after freezing and thawing. The concentrations of macroelements (Na, Mg, K and Ca) and microelements (Cu, Fe, Zn and Se) were determined in the seminal plasma and serum. The semen samples were classified into satisfactory and unsatisfactory groups according to the fresh semen quality. Results Zinc and Se levels measured in serum were associated with almost all fresh and frozen-thawed semen quality characteristics, while Fe levels were associated only with acrosomal defects in fresh semen. Zinc and Fe levels in fresh seminal plasma were associated with various quality characteristics of fresh and frozen-thawed semen, while Se level in fresh seminal plasma was not associated with any of the semen quality characteristics. Conclusions Microelements were shown to be useful as biomarkers involved in the analysis of bull sperm quality and could be used as an additional tool to predict bull semen quality after freezing and thawing. Our results confirm that the analysis of Zn and Se levels in serum and Zn, Cu and Fe levels in fresh seminal plasma can provide information to discriminate between bull semen samples with spermatozoa with high or low cryotolerance.

ABSTRACT: Studies have been performed to identify the proteins present in canine seminal plasma (SP) and relate them to sperm quality as well as to discover molecular markers of reproductive tract diseases. There is evidence that heparin-binding proteins, zinc-binding proteins, and lactoferrin as well as the matrix metalloproteinase, superoxide dismutase, catalase, and glutathione peroxidase enzymes are associated with canine sperm quality. Other studies indicate that prolactin and enzymes like arginine esterase, acid phosphatase, and alkaline phosphatase could be successfully used as biomarkers of reproductive disorders. Thus, the present literature review aims to address aspects related to proteins of the canine SP, their influence on fertility, and their importance as biomarkers of reproductive disorders.

Introduction In this study an attempt is made to find out the level of calcium in seminal plasma of normal and infertile patients. Materials and Methods Semen samples are collected from 34 normal men and 112 infertile patients. After semen evaluation seminal plasma was separated and calcium level was measured in it. Results Calcium level in mg% is recorded in each group as follows; in normozospermia (n34) 20.14 ± 1.25 (±SE), oligozoospermia (n26) 9.76 ± 1.17, azoospermia (n33) 14.65 ± 2.63, oligoasthenozoosperma (n28) 20.91 ± 1.94 and in asthenozoospermia (n25) 11.56 ± 1.68. Statistically highly significant reduction in calcium is seen in Oligozoospermia and asthenozoospermia. Conclusions The probable reasons for these two conditions are discussed.

Functional Integrity

Seminal plasma improves the functional integrity of compromised ram spermatozoa but has been reported to be toxic to sorted spermatozoa. The present study attempted to clarify this paradoxical effect and improve the functional integrity of spermatozoa following sorting and cryopreservation. The in vitro function of sorted spermatozoa (motility characteristics and membrane integrity) was examined after supplementation with differing concentrations and protein fractions of seminal plasma at various stages of the sorting and freezing process. For all experiments, spermatozoa (two males, n = four ejaculates per male) were processed through a high-speed flow cytometer before cryopreservation, thawing and incubation for 6 h (37°C). Supplementation of crude seminal plasma (CP), its low molecular weight fraction (LP; <10 kDa) or protein-rich fraction (SPP; >10 kDa), immediately before freezing improved the functional integrity of sorted spermatozoa compared with no supplementation (control), whereas supplementation after thawing had no effect for CP and LP. The protective effect of seminal plasma was not altered by increasing the amount of protein supplementation. No toxic effect of CP, SPP or LP was evident even when supplemented at high protein concentrations. It is concluded that seminal plasma protein, if added to ram spermatozoa after sorting and before freezing, can improve post-thaw sperm quality and consequently the efficiency of sorting. This effect is most likely related to protection of the spermatozoa during freeze–thawing.

IntroductionThe aim of this study is to comprehensively evaluate whether FSH administration to the male partner of infertile couples improves pregnancy rate, spontaneously and/or after assisted reproductive techniques (ART).MethodsMeta-analysis of controlled clinical trials in which FSH was administered for male idiopathic infertility, compared with placebo or no treatment. Randomization was not considered as an inclusion criterion.ResultsWe found 15 controlled clinical studies (614 men treated with FSH and 661 treated with placebo or untreated). Concerning the type of FSH, eight studies used recombinant FSH, whereas seven studies used purified FSH. Nine studies evaluated spontaneous pregnancy rate, resulting in an overall odds ratio (OR) of about 4.5 (CI: 2.17–9.33). Eight studies evaluated pregnancy rate after ART, showing a significant OR of 1.60 (CI: 1.08–2.37). Sub-dividing studies according to the FSH preparations (purified/recombinant), pregnancy rate improvement remained significant for each preparation. Eleven studies considered sperm quality after FSH treatment, finding a significant improvement of sperm concentration (2.66×106/ml, CI: 0.47–4.84), but not of concentration of sperm with progressive motility (1.22×106/ml, CI: −0.07 to 2.52). Three trials evaluated testicular volume, showing a non-significant increase in men treated (1.35 ml, CI: −0.44 to 3.14).ConclusionThe results of controlled clinical trials available in the literature indicate an improvement of pregnancy rate after FSH administration to the male partner of infertile couples, both spontaneously and after ART. However, the heterogeneity of studies, the high risk of bias and the lack of precise criteria to guide FSH administration limit the strength of these results. Future studies should be designed to identify the markers of FSH response which are helpful in the decision-making process. Meanwhile, the use of FSH in the treatment of male infertility should be cautious.
