    Reports regarding the changes in sperm concentration in different counties of the world are inconsistent. Furthermore, the reports that sprung up from specific epidemiological and experimental examinations did not include data of prior studies or geographical variations. The current study, following a previous report of massive fall in semen volume over the past 33 years, attempts to delineate the trend of altering sperm concentrations and factors responsible for this by reviewing article published from 1980 to July 2015 with geographic differences. The current study identified an overall 57% diminution in mean sperm concentration over the past 35 years ( r = -.313, p = .0002), which, when analyzed for each geographical region, identified a significant decline in North America, Europe, Asia, and Africa. An increasing trend of sperm concentration was identified only in Australia. The association of male age with such a trend ( R2 = .979) is reported. The authors also correlated male fertility with sperm concentration. Thus, this comprehensive, evidence-based literature review aims to concisely and systematically present the available data on sperm concentration from 1980 to 2015, as well as to statistically analyze the same and correlate male health with the declining pattern of sperm count in a single scientific review to serve the scientific research zone related to reproductive health. It points to the threat of male infertility in times ahead.

  2. Fulltext The more pieces, the better the puzzle: sperm concentration increases gametic compatibility

    The genetic benefits individuals receive from mate choice have been the focus of numerous studies, with several showing support for both intrinsic genetic benefits and compatibility effects on fertilization success and offspring viability. However, the robustness of these effects have rarely been tested across an ecologically relevant environmental gradient. In particular, sperm environment is a crucial factor determining fertilization success in many species, especially those with external fertilization. Here, we test the importance of sperm environment in mediating compatibility-based selection on fertilization using a factorial breeding design. We detected a significant intrinsic male effect on fertilization success at only one of four sperm concentrations. Compatibility effects were significant at the two highest sperm concentrations and, interestingly, the magnitude of the compatibility effect consistently increased with sperm concentration. This suggests that females are able to modify the probability of sperm-egg fusion as the amount of sperm available increases.

    Altered epididymal sperm count and morphology following leptin treatment has been reported recently. This study examined the effects of 42 days of leptin treatment on sperm count and morphology and their reversibility during a subsequent 56-day recovery period. Twelve-week-old male Sprague-Dawley rats were randomised into four leptin and four saline-treated control groups (n = 6). Intraperitoneal injections of leptin were given daily (60 μg Kg(-1) body weight) for 42 days. Controls received 0.1 ml of 0.9% saline. Leptin-treated animals and their respective age-matched controls were euthanised on either day 1, 21, 42 or 56 of recovery for collection of epididymal spermatozoa. Sperm concentration was determined using a Makler counting chamber. Spermatozoa were analysed for 8-hydroxy-2-deoxyguanosine and DNA fragmentation (Comet assay). Data were analysed using anova. Sperm concentration was significantly lower but fraction of abnormal spermatozoa, and levels of 8-hydroxy-2-deoxyguanosine were significantly higher in leptin-treated rats on day 1 of recovery. Comet assays revealed significant DNA fragmentation in leptin-treated rats. These differences were reduced by day 56 of recovery. It appears that 42 days of leptin treatment to Sprague-Dawley rats has significant adverse effects on sperm count and morphology that reverse following discontinuation of leptin treatment.

  4. The use of the semen analysis in predicting fertility outcome
    Arumugam K, Omar SZ
    Aust N Z J Obstet Gynaecol, 1992 May;32(2):154-7.
    PMID: 1520202
    The study investigates the use of the various parameters of the semen analysis in predicting the fertility outcome in 82 infertile couples. The sperm density, % progressive motility, % normal morphology were divided into 'normal' and 'abnormal' based on the criteria proposed by WHO. The subsequent cumulative pregnancy rates were then calculated according to this criteria. A life-table method of analysis was used. All female related fertility factors were excluded. With the exception of a sperm density of less than 20 x 10(6) per ml the other parameters showed no significant correlation with the cumulative pregnancy rates at 12 months or 24 months respectively. We concluded that the semen analysis does not predict the probable outcome of the subsequent rates even when female fertility related factors were excluded apart from a sperm density less than 20 x 10(6) per ml.

  6. Fulltext Evidence for decreasing sperm count in African population from 1965 to 2015
    Sengupta P, Nwagha U, Dutta S, Krajewska-Kulak E, Izuka E
    Afr Health Sci, 2017 Jun;17(2):418-427.
    PMID: 29062337 DOI: 10.4314/ahs.v17i2.16
    PURPOSE: This meta-analysis, following our previous reports those documented an overall 57% diminution in mean sperm concentration around the globe over past 35 years and 32.5% decline in past 50 years in European population, attempts to report the declining trend of sperm concentrations in African population between 1965 and 2015.

    METHODS: In the course of retrieval of data following MOOSE guidelines and PRISMA checklist, we found a total of fourteen studies that have been conducted during that period on altering sperm concentration in the African male.

    RESULTS: Following analysis of the data, a time-dependent decline of sperm concentration (r = -0.597, p = 0.02) and an overall 72.6% decrease in mean sperm concentration was noted in the past 50 years. The major matter of concern is the present mean concentration (20.38×106/ml) is very near to WHO cut-off value of 2010 of 15×106/ml. Several epidemic diseases, genital tract infection, pesticides and heavy metal toxicity, regular consumption of tobacco and alcohol are reported as predominant causative factors.

    CONCLUSION: This comprehensive, evidence-based meta-analysis and systematic review concisely presents the evidence of decreased sperm concentration in the African male over past 50 years with possible causative factors to serve the scientific research zone related to male reproductive health.

    Tarmizi R, Keng Chee Y, Sipangkui S, Zainuddin ZZ, Fitri WN
    Animals (Basel), 2020 Oct 23;10(11).
    PMID: 33113883 DOI: 10.3390/ani10111948
    This article describes the semen characteristics from different collection methods between captive and confiscated Malayan pangolins, Manis javanica. Semen was collected from 15 pangolins; two captive and 13 confiscated individuals at the mean weight of 9.36 ± 1.94 kg. The three semen collection methods employed were electroejaculation, rectal massage and a combination of both techniques. The semen characteristics (mean ± standard deviation) of the Malayan pangolin are volume (73.75 ± 144.57 µL), pH (7.63 ± 0.53), spermatozoa concentration (997.19 ± 728.98 × 106 /mL), total motility (59.60% ± 30.00%), progressive motility (48.95% ± 30.93%), mass motility (3.50 ± 1.50) and live spermatozoa (80.25% ± 13.45%). There was no significant difference in semen characteristics between the three collection methods. The percentages of live spermatozoa were significantly different, suggesting better samples from captive compared to confiscated animals. However, there was no significant difference in spermatozoa kinetics between the captive and confiscated samples, suggesting the potential of utilizing confiscated individuals for gamete recovery to conserve the genetic pool of pangolins. All three methods of semen collection were successfully performed in pangolins and should be considered; however, electroejaculation remains the most consistent method of obtaining semen from the species.

  8. Obesity and male infertility: Mechanisms and management
    Leisegang K, Sengupta P, Agarwal A, Henkel R
    Andrologia, 2021 Feb;53(1):e13617.
    PMID: 32399992 DOI: 10.1111/and.13617
    Obesity is considered a global health problem affecting more than a third of the population. Complications of obesity include cardiovascular diseases, type 2 diabetes mellitus, malignancy (including prostatic cancer), neurodegeneration and accelerated ageing. In males, these further include erectile dysfunction, poor semen quality and subclinical prostatitis. Although poorly understood, important mediators of obesity that may influence the male reproductive system include hyperinsulinemia, hyperleptinemia, chronic inflammation and oxidative stress. Obesity is known to disrupt male fertility and the reproduction potential, particularly through alteration in the hypothalamic-pituitary-gonadal axis, disruption of testicular steroidogenesis and metabolic dysregulation, including insulin, cytokines and adipokines. Importantly, obesity and its underlying mediators result in a negative impact on semen parameters, including sperm concentration, motility, viability and normal morphology. Moreover, obesity inhibits chromatin condensation, DNA fragmentation, increases apoptosis and epigenetic changes that can be transferred to the offspring. This review discusses the impact of obesity on the male reproductive system and fertility, including associated mechanisms. Furthermore, weight management strategies, lifestyle changes, prescription medication, and complementary and alternative medicine in the management of obesity-induced subfertility is discussed.

  9. Fulltext Quantification of coral sperm collected during a synchronous spawning event
    Teo A, Guest JR, Neo ML, Vicentuan K, Todd PA
    PeerJ, 2016;4:e2180.
    PMID: 27478697 DOI: 10.7717/peerj.2180
    Most studies of coral reproductive biology to date have focused on oocyte numbers and sizes. Only one (ex situ) study has enumerated sperm numbers, even though these data have multiple potential applications. We quantified total coral sperm and eggs per gamete bundle collected from six species in situ during a synchronous spawning event in Singapore. Egg-sperm bundles were captured midwater as they floated towards the surface after being released by the colony. For each sample, a semi-transparent soft plastic bottle was squeezed and released to create a small suction force that was used to 'catch' the bundles. This technique provided several advantages over traditional methods, including low cost, ease of use, no diving prior to the night of collection needed, and the ability to target specific areas of the colony. The six species sampled were Echinophyllia aspera, Favites abdita, F. chinensis, Merulina ampliata, M. scabricula and Platygyra pini. The mean number of sperm packaged within one egg-sperm bundle ranged from 2.04 × 10(6) to 1.93 × 10(7). The mean number of eggs per egg-sperm bundle ranged from 26.67 (SE ± 3.27) to 85.33 (SE ± 17.79). These data are critical for fertilisation success models, but the collection technique described could also be applied to studies requiring in situ spawning data at the polyp level.

    PMID: 20589353
    Antifertility agents with safety and effectiveness in terms of minimum side effects have always been a subject of debate. Many studies have been conducted on plants to observe the antifertility effect, but majority of them were toxic. Pegaga or Centella asiatica L. is one of the popular herb traditionally consumed raw amongst people in Malaysia. The main objective of the present study was to investigate the effects of Centella asiatica L. extract on rat testis.

    PMID: 17623962 MyJurnal
    Intrauterine insemination (IUI) remains a therapeutic option within means of the majority of infertile couples in Malaysia. Therefore additional information on predictors of IUI success in the local context would provide a more concrete basis for counseling patients on expectations and treatment options. A retrospective analysis of 297 couples who underwent 445 IUI cycles from Jan 2005-Mar 2006 was undertaken. Four fifths were Malay with a mean paternal and maternal age of 35.53 +/- 5.82 (range 24-59) and 33.02 +/- 4.69 (range 21-46) years respectively. Causes of infertility were idiopathic (50%), endometriosis (17%) and anovulation/polycystic ovarian syndrome (15%). Almost 10% were oligoastenoteratozoospermic with another 23% oligozoospermic or astenozoospermic. Combined male and female factors occurred in 26%. A pregnancy rate (PR) of 9.4% per cycle; 14.1% per couple with a cumulative PR of 36.7% per 4 cycles was achieved. Those who became pregnant were significantly younger (31.29 +/- 4.43 vs. 33.21 +/- 4.68 years, p = 0.011) and had more follicles (13.95 +/- 9.72 vs. 11.43 +/- 6.67, p = 0.029) at the time of insemination. PR depreciated with maternal age and semen quality. Maternal and paternal age was inversely correlated to the number of follicles recruited (r = -0.30, p < 0.0005) and progressive sperm motility (r = -0.125, p = 0.013) respectively.

    PMID: 31373711 DOI: 10.1111/and.13383
    The worldwide declining trend in male fertility has been a steady concern since the past few decades. Male infertility reportedly accounts for half of the overall infertility cases in the world. Despite the evidences of reduced fertility rates in Malaysia in the recent years, there is lack of interventions regarding the reproductive parameters in Malaysian men. Complexity in determining the underlying causatives in most of the male subfertility and infertility cases limits the scope of management. The sociodemographic impacts upon overall health as well as on reproductive health of men are undeniable. The present study has analysed the data collected from patients' records in the Fertility Clinic, International Islamic University Malaysia (IIUM), from the January 2009 until December 2018. A total of 300 male patients were included in the study and were categorised according to their seminal fluid analysis (SFA) records. The sociodemographic characteristics for each subject were analysed. The results presented significant correlations among essential sociodemographic factors, such as educational attainment, marital duration as well as the age of wife, with the levels of semen abnormalities in the subjects. The study thereby unleashes scope for further investigations focusing upon the demographic factors for better insights to ameliorate male reproductive health in the Malaysian population.

  13. Polar Quassinoids in Standardized Eurycoma longifolia Extract Formulated into a Lipid-Based Solid Dispersion to Improve Rat Sperm Count
    Ma HQ, Ebrahimi F, Low BS, Khan NAK, Chan KL
    Phytother Res, 2017 Dec;31(12):1875-1882.
    PMID: 28948658 DOI: 10.1002/ptr.5930
    Eurycoma longifolia Jack is popularly sought in Southeast Asian countries for traditional remedies to improve sexual performance and fertility. 13α(21)-Epoxyeurycomanone and eurycomanone, two major quassinoids in a root extract (TAF2) were reported to improve rat spermatogenesis and fertility. Unfortunately, these quassinoids possess low bioavailability because of high aqueous solubility and low lipid membrane permeability. Often, other possible barriers may be P-glycoprotein (P-gp) efflux in the gut and presystemic hepatic metabolism. The present study attempted to solve these problems by formulating a lipid-based solid dispersion (TAF2-SD) of optimized mixture of TAF2 and emulsifiers, which was then orally administered to rats prior to sperm count analysis. The TAF2-SD-treated rats showed significantly twofold (p sperm count than did TAF2-treated and vehicle-treated (control) rats, respectively. The study also demonstrated no significant in vitro ileal absorption changes of the quassinoids by P-gp efflux inhibitors and concentration change or secondary metabolite formation upon in vitro incubation with rat liver homogenates, suggesting that P-gp-mediated efflux and presystemic metabolism were not limiting their bioavailability. Further study on orally TAF2-treated rats confirmed that the area under the curve and bioavailability curve of each quassinoid in the absence and presence of ketoconazole were unchanged.

  14. Salvia officinalis L. Methanolic Extract Reduces Lead and Nicotine-Induced Sperm Quality Degeneration in Male Rats
    Ammar Aldaddou W, Aljohani ASM, Adewale Ahmed I, Al-Wabel NA, El-Ashmawy IM
    Chem Biodivers, 2023 Jul;20(7):e202300115.
    PMID: 37236909 DOI: 10.1002/cbdv.202300115
    Most heavy metals and industrial chemicals such as nicotine and lead cause harm to the reproduction process through a decrease in sperm motility, fertilization process, and sperm binding to the oocyte. Salvia officinalis L. (sage) has been reported to enhance serum testosterone levels and other certain biochemical enzymes. Thus, the current study is aimed at evaluating the potential health benefits of S. officinalis L. methanol extract on lead and nicotine hydrogen tartrate-induced sperm quality degeneration in male rats and also identifying some of the non-polar volatile bioactive compounds that might be attributed to the bioactivity of S. officinalis extract using gas chromatography-mass spectrometry (GC/MS). In the study, fifty-four mature male albino rats of about 220-250 g [were divided randomly and equally into 9 groups (n=6)]. Sperm quality degeneration was induced through the oral administration of 1.5 g/L of lead acetate in drinking water or peritoneal injection of 0.50 mg/kg (animal weight) nicotine hydrogen tartrate for sixty days. Two doses (200 & 400 mg/kg b.w.) of S. officinalis L. were used. The rats were anesthetized after the experimental period and then sacrificed. Blood samples were collected while the epididymis, testicle, and accessory sex organs (prostates and seminal vesical) were taken for histopathological studies. Twelve major compounds were identified through the GC/MS analysis of S. officinalis L. methanol extract. Lead and nicotine toxicity had a great effect on the rats' sperm quality causing a significant (p<0.05) decrease in the quantity of sperm and sperm motility as well as an upsurge in the abnormalities of the sperm and a reduction in the length & diameter of seminiferous tubules and size & weight of sexual organs (accessory sex glands, epididymis, and testis). The administration of S. officinalis L. methanol extract, however, had a positive impact on the sexual organ weights, semen quality & quantity, and rats' fertility, thus, ameliorating the adversative effects of both lead and nicotine. Further evaluation and isolation of the bioactive components are recommended as potential drug leads.

    Mohamed M, Sulaiman SA, Jaafar H, Sirajudeen KN
    Andrologia, 2012 May;44 Suppl 1:182-6.
    PMID: 21592175 DOI: 10.1111/j.1439-0272.2010.01159.x
    The aim of this study was to evaluate the effect of different doses of Malaysian honey on male reproductive parameters in adult rats. Thirty-two healthy adult male Sprague-Dawley rats were randomly divided into four groups (eight rats per group). Group 1 (control group) was given 0.5 ml of distilled water. Groups 2, 3 and 4 were given 0.2, 1.2 and 2.4 g kg(-1) body weight of honey respectively. The rats were treated orally by gavage once daily for 4 weeks. Honey did not significantly alter body and male reproductive organs weights. The rats in Group 3 which received honey at 1.2 g kg(-1) had significantly higher epididymal sperm count than those in Groups 1, 2 and 4. No significant differences were found for the percentage of abnormal sperm, elongated spermatid count, reproductive hormonal levels as well as the histology of the testis among the groups. In conclusion, Malaysian honey at a dose of 1.2 g kg(-1) daily significantly increased epididymal sperm count without affecting spermatid count and reproductive hormones. These findings might suggest that oral administration of honey at this dose for 4 weeks may enhance spermiogenesis in adult rats.

    Introduction: The objective of this study was to investigate the effects of lead on concentration and motility of spermatozoa recovered from epididymis and testes in mature male offspring whose mothers were exposed to different doses and concentrations of lead acetate during gestation period. Materials and Methods: Seventy two healthy mature female mice were divided into three major groups according to the number of injections involving 1, 2 and 3 injections. Each major group was subdivided into four minor groups according to the concentration dose of (0, 25, 50 and 100) mg/Kg of lead acetate. Sperm concentration, percentage of motility and grade of activity were microscopically examined and statistically analyzed. Results: A significant reduction in the sperm functions were seen in relation to an increased in the number of injections and/or concentration of lead acetate dose as compared with the control groups. Conclusion: The toxic effects of lead acetate may interfere with spermatogenesis and metabolism of spermatozoa.

    Sains Malaysiana, 2004;33.
    The mengkudu (Morinda citrifolia Linn.) plant is a well known medicinal plant. The fruits, leaves and roots of this plant have been widely used in traditional medicine. The purpose of this study was to evaluate the effects of an aqueous extract of the M. citrifolia fruits (25 mg/kg, 50 mg/kg and 100 mg/kg body weight given for a period of 30 days) on sperm quality and histology of testis in mice. Data from this study show that the epididymal sperm count, mortality, motility and sperm morphology in mice given the M. citrifolia fruit extract did not differ from that of the control group. Spermatogenesis was not affected by the treatment. The results obtained here suggest that the aqueous extract of the M. citrifolia fruit (up to 100 mg/kg) did not affect sperm quality and spermatogenesis in mice.
