Regular consumption of nuts improves sperm parameters such as motility, vitality, and morphology, potentially promoting successful reproductive outcomes in healthy males.
The researchers in this study carried out a systematic review and meta-analysis, exploring the impact of nut intake on fertility outcomes. They sourced data from four databases: Ovid MEDLINE, Embase, CINAHL, and Scopus, from their inception until June 2023. The inclusion criteria for articles were humans of reproductive age who had consumed nuts for a minimum of three months, with any consequent fertility-related outcomes reported. The researchers undertook a random-effects meta-analysis to produce a collective estimate of the effect of nut consumption on four specific sperm characteristics: total motility, vitality, morphology, and concentration.
In this review and meta-analysis, the researchers involved four studies, evaluating a total of 875 participants, composed of 646 males and 229 females. For males, two randomized control trials involving 223 individuals revealed that a daily consumption of at least 60g of nuts led to an improvement in sperm motility, vitality, and morphology, compared to those consuming fewer nuts, though it did not affect sperm concentration. Conversely, the non-randomized studies could not discern an association between nut consumption and traditional sperm parameters in males, nor could they establish a link between nut intake and embryo implantation, clinical pregnancy or live birth in males and females undergoing Assisted Reproductive Technology (ART).

Randomised Controlled Trial Date Fruit Erectile Dysfunction Female Fertility
The research employed a double-blind, placebo-controlled clinical trial approach involving infertile couples who frequented infertility clinics in Iran in 2019. The intervention group was administered with a capsule of date palm, while the control group was given a placebo. The data on the sexual function of the subjects was gathered using the female sexual function index and the International Index of Erectile function.
All areas of sexual function in both males and females, which include erectile function, orgasmic function, sexual desire, intercourse satisfaction, arousal, lubrication, and pain during intercourse, showed a significant enhancement in the group that consumed date palm in contrast to the control group. This study continued for a month and it demonstrated that date palm indeed has a favorable effect on the sexual functioning of infertile couples.
Ginger significantly improves sperm health, enhancing quality parameters like count, viability, motility, morphology and DNA integrity, thereby boosting fertility.

Systematic Review Ginger Sperm Quality Testosterone
The study investigated the impact of ginger on semen quality across different species. It focused on key sperm parameters including count, viability, motility, morphology, and DNA integrity. The research pointed to the antioxidant properties of ginger, attributed to active phenolic compounds, which disrupt the production of free radicals - these are known to cause oxidative stress and negatively impact the quality of sperm. The study also noted ginger's androgenic activity and the associated influence on the levels of gonadotropin and sex hormones, such as testosterone.
In the discussion of results, it was identified that ginger minimizes DNA failures, reduces damage to the mitochondrial genome in sperm cells, and essentially moulds a sperm with apt morphological structure. The sperm, under the influence of ginger, attains progressive motility, high viability, and increased fertility. Overall, the entire fertility indicators of sperm also saw an upswing with the usage of ginger - reinforcing its effectiveness in increasing the total motility, survival rate, the normal morphological structure of sperm, and the number of sperm cells.

Review Article Date Fruit Female Fertility Ovarian Function
The research conducted a thorough review of the role of date palm in treating infertility. The health benefits of date palm and its varied components were explored, with a focus on their effects on reproductive parameters in both sexes. The comprehensive review shed light on how the substantial nutrients and antioxidant features of date palm can be beneficial for people dealing with infertility.
In men, the study found direct links between consumption of date palm and improved hormonal levels alongside notable enhancements in seminal vesicle parameters and sperm quality. For women, this natural remedy showed a positive impact on the process of oogenesis, hormone regulation, and improving pregnancy outcomes. The focus was on the potential of date fruit as a natural enhancer of fertility, downplaying the role of any synthetic or invasive medical interventions. The study thus testifies to the innovative use of a widely available natural resource in addressing a pressing health issue.
Date palm fruit extract may mitigate some harmful effects of formaldehyde on male fertility by improving testosterone, sperm, and testicular conditions.

Experimental Study Date Fruit Sperm Quality Testosterone
The study divided thirty-two male mice of similar ages and weight ranges into four groups. The control group was given distilled water orally for 35 days. The Formaldehyde group received a Formaldehyde dose for 20 days. The third group took a Date fruit extract dose for 35 days followed by a Formaldehyde dose for 20 days while the last group was administered Date fruit extract for 35 days. Following these treatments, blood was collected and epididymis and testis tissues analyzed to evaluate sperm characteristics and conduct a histological examination respectively.
Results showed that formaldehyde administration increased sperm deformities, decreased sperm count, livability, and motility, and reduced testosterone levels in comparison to the control group. Histological assessments showed that formaldehyde induced changes in the testes, including damage to the germinal epithelium and vacuolization of the tubules. However, the consumption of Date palm fruit extract was found to ameliorate the effects noticed due to formaldehyde on testosterone levels, sperm, and testicular parameters.
Consuming walnuts can enhance sperm motility and morphology, potentially improving fertility in males with infertility issues.
2019 Current Developments in Nutrition Randomized Clinical Trial: Effect of Walnuts on Semen Parameters and Male Fertility (P18-042-19) Robbins W, Kim H, Houman J, Lee GW
Randomised Controlled Trial Sperm Quality Walnut
This study was a randomized clinical trial split into two comparison groups, all of which received typical care for male infertility. Besides the usual care, one group added 42 gm/d walnuts to their diet, while the other group included a daily nutritional supplement recommended for male reproductive health. The participants, a total of 75 in number and with varied demographic profiles, were enrolled at an infertility clinic located in a large metropolitan medical center. The study ran for 3 months, with research measures including semen analysis and blood samples at baseline and after 3 months, while dietary recall and fertility reports were obtained at various stages.
In terms of results, the group consuming walnuts showed a marked increase in sperm motility and concentration after 3 months. Simultaneously, both groups—those consuming walnuts and the group consuming the nutritional supplement—demonstrated an improvement in sperm morphology. Further, preliminary data observed over one year suggested a higher frequency of pregnancy in the group consuming walnuts, although it was not statistically significant.
