“…The analysis of sperm parameters in the study of Sobhani et al (2015) demonstrated that the general and advanced motility of frozen-thawn human spermatozoa significantly increased following incubation with the extract of the Sargassum brown algae. On the other hand, twelve seaweeds were screened for in vitro spermicidal activity in the report by Prakash et al (2014). Among these twelve seaweeds, Halimeda gracilis showed 100% inhibition of human spermatozoa at 10 µg/ml in 20 s. Furthermore, doseand time-dependent spermicidal assay revealed that the sperm was completely immobilised for 20 s. Plasma membrane of sperm was damaged due to the exposure of H. gracilis extract.…”

In vitro storage and processing of animal semen is represents a risk factor to spermatozoa vitality, potentially leading to reduced fertility. A variety of substances isolated from natural sources may exhibit protective or antioxidant properties on the spermatozoon, thus extending the lifespan of stored ejaculates. Chlamydomonas has been shown to possess antimicrobial, anti-inflammatory and antioxidant properties, turning the extract into a potential candidate for preserving liquid animal semen during in vitro storage. This study compared the ability of different concentrations of the Chlamydomonas reinhardtii extract on the motility, viability and superoxide production of bovine spermatozoa during different time periods (0, 2, 6, 12 and 24h) of in vitro culture. Spermatozoa motility was assessed using the SpermVisionTM CASA (Computer aided sperm analysis) system. Cell viability was examined using the metabolic activity MTT assay and the nitroblue-tetrazolium (NBT) test was applied to quantify the intracellular superoxide formation. The CASA analysis revealed that the Chlamydomonas extract supplementation was able to prevent a rapid decline of spermatozoa motility, especially in the case of concentrations ranging between 1 and 5 µg/mL (P

In vitro spermicidal effect of Thevetia Peruviana leaves on human spermatozoa

An in vitro spermicidal effect of aqua-methanolic (2:3) extract of Thevetia peruviana leaves on human spermatozoa was evaluated in a dose-dependent manner (20, 40, 80 and 160 mg/ml) at a 1:1 ratio. Sperm motility, viability, hypo-osmotic swelling (HOS) and acrosomal status and function tests were performed immediately (20 s), and after 5 and 10 min of exposure of the spermatozoa to the extract of Thevetia peruviana

“…Likewise, Halimeda gracilis demonstrated a 100% suppression of human sperms due to sperm’s plasma membrane being damaged at a dosage of 10 mg/ml after 20 s of contact time. A phytochemical assessment of Halimeda gracilis extracts revealed the existence of secondary metabolites, including sugar, flavonoids, alkaloids, and protein (Prakash et al 2014 ).…”

The development and recycling of biomass production can partly solve issues of energy, climate change, population growth, food and feed shortages, and environmental pollution. For instance, the use of seaweeds as feedstocks can reduce our reliance on fossil fuel resources, ensure the synthesis of cost-effective and eco-friendly products and biofuels, and develop sustainable biorefinery processes. Nonetheless, seaweeds use in several biorefineries is still in the infancy stage compared to terrestrial plants-based lignocellulosic biomass. Therefore, here we review seaweed biorefineries with focus on seaweed production, economical benefits, and seaweed use as feedstock for anaerobic digestion, biochar, bioplastics, crop health, food, livestock feed, pharmaceuticals and cosmetics. Globally, seaweeds could sequester between 61 and 268 megatonnes of carbon per year, with an average of 173 megatonnes. Nearly 90% of carbon is sequestered by exporting biomass to deep water, while the remaining 10% is buried in coastal sediments. 500 gigatonnes of seaweeds could replace nearly 40% of the current soy protein production. Seaweeds contain valuable bioactive molecules that could be applied as antimicrobial, antioxidant, antiviral, antifungal, anticancer, contraceptive, anti-inflammatory, anti-coagulants, and in other cosmetics and skincare products.
