*Combination of onions, ginger, scent leaf, orange peel, watermelon seeds, carrot, tiger nut, coconut water, dates improves sex drive in men, women
Love is in the air. February is usually associated with love. The celebration is heightened as Valentine approaches. Couples seek for help to better satisfy their partners in bed. Men and women, boys and girls go for sex drive boosting drugs and drinks. Unfortunately most of these products come with unpleasant side effects.
But scientists have in recent clinical studies identified local foods and herbs that can, not only boost sex drive in men and women but improves sperm parameters and pregnancy rate.The recent clinical trial of 40 infertile couples referred to Alzahra Hospital in Iran was published in International Journal of Women’s Health and Reproduction Sciences.
The researchers investigated the efficacy of a combination of seven plants including Allium cepa (onion), Zingiber officinale (ginger), Ocimum basilicum (scent leaf), Cinnamomum verum (cinnamon tree), Citrus sinensis (orange) peel, Citrullus lanatus (watermelon) seeds and Daucus carota (carrot) seeds in boosting fertility and pregnancy rate in humans.
Commonly called cinnamon tree, Cinnamomum verum belongs to the plant family Lauraceae. To the French it is called cannellier de Ceylan while in Nigeria; it is called imeguru or ohio.The herbal combination in a form of 700 mg capsule was taken once daily for six months. Before and after treatment, the patients’ blood and semen samples were collected and analyzed.
According to the results, the number of sperms, overall motility, forward movement, and normal morphology of sperms after treatment showed significant improvement. Also patients’ blood glucose levels meaningfully reduced after treatment. The researchers noted: “The total volume of semen, total cholesterol, testosterone, and Luteinizing hormone (LH) levels did not significantly differ with use of the compound herbal medicine. Seven couples during the study and after six months of receiving medication got pregnant.
“Consumption of compound herbal medicine with the lowest risk and cost, significantly improves sperm parameters. It seems that the mechanism of action is through counteracting the effects of oxidative stress.”LH is a hormone produced by gonadotropic cells in the anterior pituitary gland. In females, an acute rise of LH (“LH surge”) triggers ovulation and development of the corpus luteum.
The study is titled “The Effect of Compound Herbal Remedy Used in Male Infertility on Spermatogenesis and Pregnancy Rate” was conducted by researchers from Women’s Reproductive Health Research Center, Tabriz University of Medical Sciences Tabriz, Iran.
Researchers have shown how fresh onion juice enhanced copulatory behaviour in male rats with and without paroxetine-induced sexual dysfunction.The study was published in Experimental Biology and Medicine. The researchers noted: “Onion (Allium cepa) is one of the most commonly cultivated species of the family Liliaceae, and has long been used in dietary and therapeutic applications. Treatment with fresh onion juice has been reported to promote testosterone production in male rats. Testosterone is the male sex hormone responsible for enhancing sexual libido and potency. This study aimed to investigate the effects of onion juice on copulatory behavior of sexually potent male rats and in male rats with paroxetine-induced sexual dysfunction. Sexually experienced male rats were divided into seven groups: a control group, three onion juice-treated groups, a paroxetine-treated group, and two groups treated with paroxetine plus different doses of onion juice. At the end of the treatments, sexual behavior parameters and testosterone levels were measured and compared among the groups.
“Administration of onion juice significantly reduced mount frequency and latency and increased the copulatory efficacy of potent male rats. In addition, administration of onion juice attenuated the prolonged ejaculatory latency period induced by paroxetine and increased the percentage of ejaculating rats. Serum testosterone levels increased significantly by onion juice administration. However, a significant reduction in testosterone because of paroxetine therapy was observed. This reduction was restored to normal levels by administration of onion juice.
“This study conclusively demonstrates that fresh onion juice improves copulatory behavior in sexually potent male rats and in those with paroxetine-induced sexual dysfunction by increasing serum testosterone levels.”
Researchers have demonstrated how ethanol extract of the leaves of guava (Psidium guajava) enhances sperm output in healthy Wistar rats.The study was published in African Journal of Medicine and Medical Sciences.The researchers from the University of Lagos (UNILAG) noted: “Reactive oxygen species (ROS), among other factors, have been implicated in the aetiology of male infertility. Thus, the roles of antioxidants at improving sperm production and quality are being investigated. The present study was designed to assess the effect of the ethanol extract of fresh leaves of Psidium guajava on the sperm parameters of healthy male Wistar rats.
“A total of 18 rats, weighing between 108-124 g, were divided into 3 groups of 6 animals each. Animals in groups 1 and 2 were administered 250 mg/kg/d and 500 mg/kg/d of guava leaf extract (GLE) orally for 53 days respectively. Group 3 animals received normal saline. Sperm count increased from 56.2+/-0.3 (x10(6)) in the control to 57.1+/-0.2 (x10(6)) in group one animals, and from 56.2+/-0.3 (x10(6)) in the control to 72.3+/-0.4 (x10(6)) in group two animals. Similarly, dose-dependent increases in the percentages of motile spermatozoa were observed in GLE-treated animals compared to the control group. These findings suggest that the extracts of the leaves of Psidium guajava possess beneficial effects on sperm production and quality, and may thus improve the sperm parameters of infertile males with oligospermia (deficiency of sperm cells in the semen) and non-obstructive azoospermia (complete lack of sperm in the ejaculate).”
A double-blind randomized clinical trial of ginger extract has demonstrated how it boosts fertility in men.The study was published in the International Journal of Reproductive BioMedicine. The study is titled “The influence of ginger (Zingiber officinale) on human sperm quality and DNA fragmentation: A double-blind randomized clinical trial.”According to the Iranian researchers, although the effectiveness of ginger as an antioxidant agent has been exploited, little human research has been conducted on its activity on male reproductive functions.
The study was designed to investigate the effects of ginger on sperm Deoxy Nucleic Acid (DNA)/genetic material fragmentation (SDF) in infertile men. The randomized double blind, placebo-controlled trial with a 1:1 allocation was performed on 100 infertility treatment candidates who were admitted to Royan Institute for Reproductive Biomedicine, Tehran, Iran. Patients were randomly assigned to receive one of two treatments: ginger and placebo. Patients were given a three-month oral treatment (members received capsules containing 250 mg of ginger powder twice a day in ginger and a placebo in other group). Before and after treatment, standardized semen samples were obtained to determine sperm concentration, motility, and SDF according to World Health Organization
The results showed there was no significant difference between two groups regarding SDF at baseline in cases and in controls. The average positive percentage of SDF in patients receiving ginger was lower compared with placebo after three month of treatment (p=0.02). In multivariate analysis, SDF was significantly lower in patients receiving ginger compared with placebo (mean difference. There were no significant differences between two groups regarding to semen parameters. The researchers concluded: “The present study has demonstrated that ginger in a controlled study of efficacy was effective in decreasing SDF in infertile men.”
The fruit and seeds of watermelon has been show to improve sexual functions.The study published in International Journal Women’s Health Reproduction Sciences is titled: “Effects of Watermelon Seed Extract (Citrullus vulgaris) on
Spermatogenesis in Rat.”
Previous studies confirmed antioxidants have significant effect on infertility by their role on reactive oxygen species. The aim of the study was to see effect of this herb on spermatogenesis.Wistar male rats (n=20) were allocated into two groups, control group (n=10) and Citrullus vulgaris (C.V) group (n=10) that received 55mg.kg-1.day-1 C.V by gavage method for four weeks; however, the control group just received an equal volume of distilled water daily. Animals were kept in standard condition. In 28th day, testicle tissues were collected then prepared for sperm analysis.
Results showed sperm parameters significantly increased in experimental group in comparison to control group.They concluded: “Since in our study 55mg.kg-1 (C.V) has significantly increased sperm population, motility and viability, it seems that using it in infertile patients has beneficial effects.”Also, researchers have investigated the effect of watermelon (Citrullus lanatus) flesh extract on sexual behaviour of male rats.
The study was published in Chiang Mai University Journal of Natural Sciences.The effects of red watermelon (Citrullus lanatus) flesh extract on male sexual behavior as well as its adverse effects were investigated using animal models.The suspension of the flesh extract was administered orally at doses of 100, 500 and 1000 mg/kg to different groups of male rats (five) daily for 22 days. The receptive female rats were prepared by hormonal treatment. The mating behaviour was investigated and compared with the standard reference drug, sildenafil citrate. The adverse effects of the plant extract were also evaluated by observing at least once daily for any sign of toxicity, water and food intake, stress and changes in behavior.
The results indicated that oral administration of watermelon flesh extract caused a significant increase in mounting frequency, intromission frequency and ejaculatory latency in first and second series and caused a significant decrease in the mounting latency and intromission latency. The extract at a dose of 1000 mg/kg did not produce clinical signs of toxicity or mortality in any of animals during the treatment duration. The weight of body and reproductive organs showed no significant difference in the flesh extract groups compared to the control group.
The researchers noted: “Based on the aphrodisiac property of watermelon in animal models observed in this present study, this plant may be useful for men with erectile dysfunction. In addition, watermelon flesh extract did not produce undesirable effects on male rats, indicating that its short-term use is apparently safe. Thus, our findings support the use of watermelon flesh for increasing potency in males.”
Also, Nigerian researchers have demonstrated how extracts of tiger nuts (Cyperus esculentus) significantly increased gonadotropins, testosterone, and sperm parameters in a dose-dependent fashion.The study published in the Journal of Medical and Applied Biosciences is titled “Effect of Methanolic Extract of Cyperus esculentus L. (Tigernut) on Luteinizing Hormone, Follicle Stimulating Hormone, Testosterone, Sperm Count and Motility in Male Albino Wistar Rat
