“…This effect of follicular fluid has been studied in other species as a human (Briton-Jones et al, 2001;Chao, Ng, Kao, Wei, & Hong, 1991;Esmaeilpour et al, 2014;Falcone et al, 1991;Getpook & Wirotkarun, 2007;Jeon et al, 2001;Wang, Storeng, Dale, Åbyholm, & Tanbo, 2001) and porcine (Lee, Kuo, Kao, Hong, & Wei, 1992). In contrast, some studies have found that increased follicular fluid concentration affects sperm motility (Leemans et al, 2015;McNutt & Killian, 1991; Olds-Clarke, Way, Suarez, & Killian, 1994;Mortimer & Camenzind, 1989).…”

The follicular fluid exerts an effect on the sperm capacitation of several species; however, these effects vary according to species, both in the sperm motility and in the subsequent acrosome reaction. In this study, the effect of alpaca follicular fluid (aFF) on the motility and acrosome reaction of alpaca spermatozoa was observed, using follicular fluid of three follicle sizes: small (<3 mm), medium (3-6 mm) and large (>6 mm), in a concentration of 30%. Sperm motility at the first hour of incubation with aFF of small follicles was 48.0%, with aFF of medium follicles it was 43.33% and with aFF of large follicles, it was 34.53%, while control averaged 26.00%. At the second hour, control achieved an average of 28.13%, treatment with aFF from small follicles showed an average of 46.53%, with aFF from medium follicles it was 40.00% and with aFF from large follicles it was 35.60%. The acrosome reaction after 4 hours of incubation was 30.06% for control, whereas for aFF of small follicles it was 66.3%, with aFF of medium follicles it was 58.86% and for aFF of large follicles, it was 67.63%. In the case of sperm motility, a significant difference is demonstrated for all treatments in relation to the control at the first hour, whereas only the treatments with aFF of small and medium follicles show a significant difference with respect to the control at the second hour. In the case of the acrosome reaction, all treatments with follicular fluid show a significant difference with respect to the control. It was concluded that alpaca follicular fluid favours sperm capacitation and the acrosome reaction in alpaca spermatozoa.

The use of pharmacological adjuvants to enhance sperm function is a real possibility and a very attractive proposition. However, the role of such adjuvants must be well defined to maximize therapeutic outcome for specific patient populations. Platelet-activating factor (PAF) is a potent signalling phospholipid that has been implicated in a number of biological activities. In the field of reproductive biology, PAF has been shown to have an important role in ovulation, sperm function, embryo implantation, fetal lung maturation, and initiation and maintenance of parturition. Although the exact mechanisms are not clear, it has been demonstrated in several species that PAF can influence sperm function by affecting the motility, capacitation, acrosome reaction and fertility of spermatozoa. The reproductive significance of PAF activity in spermatozoa and fertilization and its role in the establishment of pregnancy requires further study. Understanding the role of PAF in a reproductive process, such as in intrauterine insemination, could eventually lead researchers to explore its role in more complex reproductive technologies. This review summarizes the current research on the significant role of PAF in male mammalian reproductive functions, as well as its possible application in some assisted reproductive technologies.
