Gumerova E, Rimmer MP, Gellatly SA. Do sperm and lubricants gel well with each other? A systematic review. HUM FERTIL 2024; 27:2285349. [PMID: 38044638 DOI: 10.1080/14647273.2023.2285349] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2023] [Accepted: 10/20/2023] [Indexed: 12/05/2023]
Abstract
Vaginal lubricants are commonly used to aid sexual pleasure and/or to help combat vaginal dryness and dyspareunia. Several studies have reported their impact on sperm function, however there are no published guidelines to help healthcare professionals and couples select a vaginal lubricant that is 'sperm-safe'. To address this, we conducted a literature search using both PubMed and Scopus to identify and appraise manuscripts that reported the impact of lubricants on sperm function. We did not restrict the literature search by year of publication, and we only included manuscripts that looked at the impact of vaginal lubricants on human sperm. The quality of the eligible studies was assessed using the Björndahl et al., (2016) checklist for semen analysis, as most of the studies reported the findings of a basic semen analysis. A total of 24 articles were eligible for analysis with a total of 35 vaginal lubricants (that were available to buy over the counter) being included, 2 of which studied the effect of vaginal lubricants on sperm function in vivo, and 22 being conducted in vitro. KY Jelly, PreSeed and Astroglide were most studied, with most manuscripts focussing on their impact on sperm motility. A paucity of data on most lubricants combined with methodological variations between studies and limited/no reporting on pregnancy outcomes means greater efforts are required before an evidence-based guideline can be published.

Abstract
Lubricants play a pivotal role in human reproductive health, particularly concerning their impact on sperm parameters. In this systematic review, we assess the implications of both synthetic and natural or organic lubricants on sperm health and fertility, based on a compilation of 20 distinct studies. Synthetic lubricants, including K-Y Jelly, Replens, and Astroglide, predominantly containing ingredients like methylparaben and glycerin, have been linked to detrimental effects on sperm motility and chromatin integrity. Chemical characteristics, notably osmolality and pH, are central to understanding these effects. Despite the World Health Organization's osmolality recommendation of 380 mOsm/kg, many commercial products surpass this. Natural solutions offer varied results, while olive oil exhibits unfavorable effects on sperm health, egg white proves non-toxic, potentially benefitting sperm health. Conversely, Pre-Seed, widely endorsed in the research community, generally demonstrates minimal adverse impact on sperm. The review highlights the significance of lubricant selection in evidence-based reproductive strategies.

Abstract
Male infertility (MI) and male sexual dysfunction (MSD) can often coexist together due to various interplay factors such as psychosexual, sociocultural and relationship dynamics. The presence of each form of MSD can adversely impact male reproduction and treatment strategies will need to be individualized based on patients' factors, local expertise, and geographical socioeconomic status. The Asia Pacific Society of Sexual Medicine (APSSM) and the Asian Society of Men's Health and Aging (ASMHA) aim to provide a consensus statement and practical set of clinical recommendations based on current evidence to guide clinicians in the management of MI and MSD within the Asia-Pacific (AP) region. A comprehensive, narrative review of the literature was performed to identify the various forms of MSD and their association with MI. MEDLINE and EMBASE databases were searched for the following English language articles under the following terms: "low libido", "erectile dysfunction", "ejaculatory dysfunction", "premature ejaculation", "retrograde ejaculation", "delayed ejaculation", "anejaculation", and "orgasmic dysfunction" between January 2001 to June 2022 with emphasis on published guidelines endorsed by various organizations. This APSSM consensus committee panel evaluated and provided evidence-based recommendations on MI and clinically relevant MSD areas using a modified Delphi method by the panel and specific emphasis on locoregional socio-economic-cultural issues relevant to the AP region. While variations exist in treatment strategies for managing MI and MSD due to geographical expertise, locoregional resources, and sociocultural factors, the panel agreed that comprehensive fertility evaluation with a multidisciplinary management approach to each MSD domain is recommended. It is important to address individual MI issues with an emphasis on improving spermatogenesis and facilitating reproductive avenues while at the same time, managing various MSD conditions with evidence-based treatments. All therapeutic options should be discussed and implemented based on the patient's individual needs, beliefs and preferences while incorporating locoregional expertise and available resources.

Abstract
Couples trying to conceive or providing samples for Assisted Reproductive Technologies (ART) are advised against the use of lubricant-gels due to the risk of sperm-toxicity. However, gels now exist which are specifically formulated to help couples conceive but without consensus on their toxicity relative to non-specialist products. This study tested gels recently introduced as 'sperm friendly' (FertilSafe Plus, Fertile Check) alongside established lubricants intended for pleasure only using a recently published toxicity testing regime. Computer Assisted Sperm Analysis (CASA) was performed at 1 and 2 h on donor sperm (n = 12) pre-incubated with each gel (10% v/v) and controls. All gels led to a significant loss of motility/velocity at 1 and 2 h (p < 0.01), with the most significant loss from the 2 Durex pleasure products (11% and 15%, vs 47% progression) at 60 min, although these performed better than saliva (used as negative control). Incubation with FertilSafePlus led to the smallest loss of motility (24% vs 47%) at 1 h. Saliva and products designed for lubrication only exhibited the most negative effect on motility and those marketed as 'sperm safe' could be considered the best performers. Whether these affects are due to direct toxicity or are indirect due to other factors such as viscosity, pH or osmolality remains uncertain.

Abstract
Background Semen analysis is a common test conducted for diagnosing the cause of male infertility, so using an innocuous lubricant can be beneficial to reduce the semen collection difficulties. Aims In this study, the effects of BabyDance™ lubricant gel, a paraben-free lubricant, on sperm parameters were investigated. Study Setting and Design It was a prospective study and a total of 45 individuals were enrolled. Materials and Methods First, the semen samples of 20 patients referred to Royan Research Institute were incubated with different concentrations of gel, and subsequently, the sperm motility and vitality were evaluated. In the second phase, 25 individuals who had a spermogram test were asked to apply the gel in the new semen examination. Statistical Analysis Obtained data were statistically analysed using SPSS software. Results The results of the in vitro phase revealed that this gel does not affect the pH, sample colour, viability, total motility and progressive and non-progressive motility of spermatozoa at any concentration. The second phase results also represented no difference in spermatozoal characteristics with and without gel use. Moreover, 100% of the participants in the second phase were satisfied with the gel and recommended that to other patients. Conclusion It was concluded that this gel can be considered a harmless product to sperm and can be a beneficial option for clients referring to infertility centres that facilitate the semen collection process.

J Hum Reprod Sci 2021; 14:162-166. [PMID: 34316232 PMCID: PMC8279066 DOI: 10.4103/jhrs.jhrs_128_18] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2018] [Revised: 11/28/2018] [Accepted: 05/11/2021] [Indexed: 11/12/2022] Open
Abstract
Context: Some vaginal lubricants and ultrasound gels are known to be detrimental to sperm function and therefore could negatively affect fertility. Aims: The aim of the current study was to develop a sperm motility index (SMI) to test the sperm toxicity of ultrasound gels and vaginal lubricants used in reproductive medicine. Settings and Design: Two ultrasound gels (Aquasonic® and Kefus®) and five vaginal lubricants (Vaginesil™, Velastisa®, K-Y Jelly®, Control®, and Durex®) were studied. Three different concentrations (1%, 5%, and 10%) of each lubricant were tested. Subjects and Methods: SMI was calculated dividing the percentage of progressively motile sperm in each tested gel by that in the control at 0.5, 1, 2, and 24 h of incubation at 5% of CO2 and 37°C. SMI values <0.75 indicate sperm toxicity. Statistical Analysis Used: The main outcome measured was SMI for each concentration and time of incubation. Results: Only Durex® did not show any deleterious effect on sperm quality. The rest of lubricants presented different degrees of toxicity. Vaginesil™ resulted in toxic for all concentrations and incubation periods (SMI < 0.12). Control® and Velastisa® presented toxicity at 10% after 2 h, while K-Y Jelly® showed toxicity at 10% from 1 h of incubation. Regarding ultrasound gels, Aquasonic® showed toxic effects after only 0.5 h (SMI = 0.70 ± 0.15), while Kefus® showed slightly toxic effects after 2 h (SMI 0.69 ± 0.07). Conclusions: SMI is an accurate tool to evaluate sperm toxicity. One of the main strengths of the article is the inclusion of representative semen samples and known products used worldwide. This study has a relevant clinical translation since it highlights the importance of evaluating the possible sperm toxicity of simple products used in reproductive medicine.

Abstract
It is estimated that infertility affects 8-12% of couples globally, with a male factor being a primary or contributing cause in approximately 50% of couples. Causes of male subfertility vary highly, but can be related to congenital, acquired, or idiopathic factors that impair spermatogenesis. Many health conditions can affect male fertility, which underscores the need for a thorough evaluation of patients to identify treatable or reversible lifestyle factors or medical conditions. Although semen analysis remains the cornerstone for evaluating male infertility, advanced diagnostic tests to investigate sperm quality and function have been developed to improve diagnosis and management. The use of assisted reproductive techniques has also substantially improved the ability of couples with infertility to have biological children. This Seminar aims to provide a comprehensive overview of the assessment and management of men with infertility, along with current controversies and future endeavours.

Abstract
Multi-walled carbon nanotubes (MWCNTs) have been widely used in sewage disposal, water purification, and disinfection. Co-exposure to MWCNTs and heavy metal ions is common during water disposal. However, the hepatotoxicity of co-exposure to MWCNTs and lead ions for nonalcoholic fatty liver disease (NAFLD) subjects has not been investigated. NAFLD mice were fed intragastrically with MWCNTs and lead acetate (PbAc). Combined administration of MWCNTs and PbAc significantly damaged the liver function, and aggravated the nonalcoholic steatohepatitis phenotype as well as the hepatic fibrosis and steatosis in NAFLD mice. Furthermore, MWCNTs and PbAc significantly induced apoptosis in primary hepatocytes isolated from NAFLD mice. Combined administration of MWCNTs and PbAc also resulted in hepatic lipid peroxidation by inducing antioxidant defense system dysfunction, and significantly enhanced the expression levels of inflammatory cytokines in NAFLD mice livers. Meanwhile, combined administration of MWCNTs and PbAc may exert its hepatotoxicity in the NAFLD via inhibiting the adenosine 5'-monophosphate activated protein kinase (AMPK)/peroxisome proliferator-activated receptors γ (PPARγ) pathway. Taken together, we conclude that co-exposure to MWCNTs and PbAc can remarkably aggravate the hepatotoxicity in NAFLD mice via inhibiting the AMPK/PPARγ pathway. This study may provide a biosafety evaluation for the application of nanomaterials in wastewater treatment.

Abstract
BACKGROUND A majority of US women report past use of vaginal lubricants to enhance the ease and comfort of intimate sexual activities. Lubricants are also administered frequently in clinical practice. We sought to investigate if hyperosmolar lubricants are toxic to the vaginal mucosal epithelia. METHODS We tested a panel of commercially available lubricants across a range of osmolalities in human monolayer vaginal epithelial cell (VEC) culture and a robust 3-dimensional (3-D) VEC model. The impact of each lubricant on cellular morphology, cytotoxicity, barrier targets, and the induction of inflammatory mediators was examined. Conceptrol, containing nonoxynol-9, was used as a cytotoxicity control. RESULTS We observed a loss of intercellular connections, and condensation of chromatin, with increasing lubricant osmolality. EZ Jelly, K-Y Jelly, Astroglide, and Conceptrol induced cytotoxicity in both models at 24 hours. There was a strong positive correlation (r = 0.7326) between lubricant osmolality and cytotoxicity in monolayer VECs, and cell viability was reduced in VECs exposed to all the lubricants tested for 24 hours, except McKesson. Notably, select lubricants altered cell viability, barrier targets, and inflammatory mediators in 3-D VECs. CONCLUSIONS These findings indicate that hyperosmolar lubricants alter VEC morphology and are selectively cytotoxic, inflammatory, and barrier disrupting in the 3-D VEC model.

Abstract
BACKGROUND In attempting to formulate potential WHO guidelines for the diagnosis of male infertility, the Evidence Synthesis Group noted a paucity of high-quality data on which to base key recommendations. As a result, a number of authors suggested that key areas of research/evidence gaps should be identified, so that appropriate funding and policy actions could be undertaken to help address key questions. OBJECTIVES The overall objective of this Consensus workshop was to clarify current knowledge and deficits in clinical laboratory andrology, so that clear paths for future development could be navigated. MATERIALS AND METHODS Following a detailed literature review, each author, prior to the face-to-face meeting, prepared a summary of their topic and submitted a PowerPoint presentation. The topics covered were (a) Diagnostic testing in male fertility and infertility, (b) Male fertility/infertility in the modern world, (c) Clinical management of male infertility, and (d) The overuse of ICSI. At the meeting in Cairo on February 18, 2019, the evidence was presented and discussed and a series of consensus points agreed. RESULTS The paper presents a background and summary of the evidence relating to these four topics and addresses key points of significance. Following discussion of the evidence, a total of 36 consensus points were agreed. DISCUSSION The Discussion section presents areas where there was further debate and key areas that were highlighted during the day. CONCLUSION The consensus points provide clear statements of evidence gaps and/or potential future research areas/topics. Appropriate funding streams addressing these can be prioritized and consequently, in the short and medium term, answers provided. By using this strategic approach, andrology can make the rapid progress necessary to address key scientific, clinical, and societal challenges that face our discipline now and in the near future.

Vaginal lubricants in the couple trying-to-conceive: Assessing healthcare professional recommendations and effect on in vitro sperm function. PLoS One 2019; 14:e0209950.

Abstract
Vaginal lubricants are commonly used by couples trying-to-conceive. However, most vaginal lubricants are sperm toxic and therefore should not be used by couples trying-to-conceive. Despite this, lubricant sperm toxicity is insufficiently reported and guidance for healthcare professionals (HCPs) is absent. In this study, lubricant-related practices of fertility-based HCPs in Scotland were sampled via an online survey. Lubricants identified as being utilised in the fertility setting were subsequently incubated with prepared sperm samples to establish effects on sperm motility. HCP recommendations (n = 32) on lubricant use were varied although knowledge related to sperm toxicity was generally poor. HCPs infrequently asked about lubricant use and were unaware of guidance in this area. Aquagel, the only prescribed lubricant identified in this study, reduced sperm progressive motility to 49% of control after 10 minutes, even at concentrations as low as 5%. Vitality testing suggested the deterioration in progressive motility with Aquagel was not as a result of cell death. Conversely, Pré Vaginal Lubricant, a 'sperm-safe' lubricant, did not significantly affect any markers of sperm function assessed. Development of clinical guidance in this area is recommended to ensure HCPs deliver informed advice as lubricant use in couples trying-to-conceive may inadvertently contribute to delay in conception.

Abstract
OBJECTIVE To assess the extent to which lubricant use during intercourse is associated with time to pregnancy (TTP). DESIGN Prospective cohort study. SETTING Denmark and North America. POPULATION A total of 6467 women aged 18-49 years who were not using contraception or fertility treatment. METHODS We pooled data from two continuing prospective cohort studies of pregnancy planners in Denmark (2011-2017) and North America (2013-2017). Female participants completed bimonthly questionnaires for 12 months or until they reported pregnancy. After restricting the study to women without a history of infertility who had been trying to conceive for six or fewer cycles at enrollment, 6467 women were retained for analysis. Self-reported lubricant use was categorised as water-based/not pH balanced, water-based/pH balanced 'fertility friendly', silicone-based, oil-based, or a combination of these. We used proportional probability models to calculate fecundability ratios (FRs) and 95% confidence intervals (95% CIs) for the association between lubricant use and fecundability, after adjusting for cohort and sociodemographic and lifestyle factors. MAIN OUTCOME MEASURE Fecundability. RESULTS At baseline, 17.5% of participants reported the use of lubricants, most commonly water-based/not pH balanced (11.4%). Compared with non-use of lubricants, FRs were 1.02 (95% CI 0.93-1.11) for water-based/not pH-balanced lubricant use, 1.01 (95% CI 0.86-1.18) for water-based/pH balanced 'fertility friendly' lubricant use, 1.23 (95% CI 0.94-1.61) for oil-based lubricant use, and 1.27 (95% CI 0.93-1.73) for silicone-based lubricant use. Associations between oil-based lubricant use and fecundability were inconsistent across subgroups of study cohort, age, parity, and intercourse frequency. CONCLUSIONS Lubricant use was not associated with reduced fecundability in the preconception cohorts of pregnancy planners studied. TWEETABLE ABSTRACT Lubricant use during intercourse was not associated with time to pregnancy in a study of pregnancy planners.

Abstract
Vaginal dryness is a common condition that is particularly prevalent during and after the menopause, and is one of the symptoms of vulvovaginal atrophy/genitourinary syndrome of menopause. The impact of vaginal dryness on interpersonal relationships, quality of life, daily activities, and sexual function can be significant, but is frequently underestimated. Furthermore, barriers exist to treatment-seeking, and this condition is often underreported and undertreated. Greater education about vaginal dryness and the range of available treatments is essential to encourage more women to seek help for this condition. Personal lubricants and moisturizers are effective at relieving discomfort and pain during sexual intercourse for women with mild to moderate vaginal dryness, particularly those who have a genuine contraindication to estrogen, or who choose not to use estrogen. However, there is a distinction between lubricants and moisturizers, and notable differences between commercially available products. Women should be advised to choose a product that is optimally balanced in terms of both osmolality and pH, and is physiologically most similar to natural vaginal secretions. A series of recommendations for the use of vaginal lubricants and moisturizers, either on their own or in combination with systemic or topical hormone replacement therapy, is presented.

[PMID: 25599039 PMCID: PMC4295943 DOI: 10.5653/cerm.2014.41.4.165] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2014] [Revised: 10/15/2014] [Accepted: 10/23/2014] [Indexed: 11/06/2022] Open
Abstract
Objective The objective of this study is to estimate the effects of Inclear, a feminine cleanser, on sperm motility. Methods Semen samples were obtained from infertile male patients. Following liquefaction, the raw semen samples were diluted with Ham's F-10 nutrient mixture medium containing 0.4% human serum albumin solution at a ratio of 1:3. The semen samples were subsequently centrifuged to separate the seminal plasma from the serum. The supernatant was discarded, and the pellet was resuspended. The sample was again centrifuged to remove cell debris, and the supernatant was removed. The final pellet was gently loosened by resuspension and incubated in medium alone as a control, and in a 10% solution of the medium plus Inclear. A sampling time of 30 minutes was selected on the basis of sperm transport studies. Sperm motility was evaluated with computer-assisted sperm analysis. Results A total of 20 samples were analyzed. The mean age of patients was 34.40±2.96 years. There was no difference in sperm concentration and motility in the two samples at 0 minute and 30 minutes of incubation. In both semen samples, the sperm concentration and motility decreased after an incubation period of 30 minutes. However, there was no statistical difference between the samples. Sperm concentration and motility were not significantly different between the control and Inclear samples after 0 minute and 30 minutes of incubation. Conclusion Inclear has no negative effects on sperm motility. This product can be recommended to pregnancy planners for vaginal hygiene and as a vaginal lubricant.
