What thresholds for total sperm count, sperm concentration, progressive motility, and total progressive motile sperm count TPMC are associated with earlier time-to-conception in couples undergoing fertility evaluation? Values well above the World Health Organization WHO references for total sperm count, concentration, and progressive motility, and values up to million for TPMC were consistently associated with earlier time-to-conception and higher conception rates. Although individual semen parameters are generally not able to distinguish between fertile and infertile men, they can provide clinically useful information on time-to-pregnancy for counseling patients seeking fertility treatment. Compared to the conventional semen parameters, TPMC might be a better index for evaluating the severity of male infertility. We used data from a longitudinal cohort study on subfertile men from to and included men with initial semen analysis SA in the study. Men from subfertile couples who underwent a SA within the study period were included, and 5-year follow-up data were collected to capture conception data. We also plotted continuous values of semen parameters in predicting 5-year conception rates and time-to-conception. These patients were younger and had higher values of sperm concentration, progressive motility, and TPMC. Similar results were observed in the natural conception cohort. For the natural conception cohort without major female factor, the TPMC cut-off was 20 million. In the visual assessment of the graphs for the continuous semen parameter values, 5-year conception rates and time-to-conception consistently plateaued at higher values of sperm concentration, total sperm count, progressive motility, and TPMC compared to the WHO reference levels and our calculated thresholds. For TPMC, values up to — million were still associated with a better conception rate and time-to-conception in the visual assessment of the curves. There was limited information on female partners and potential for inaccuracies in capturing less severe female infertility diagnoses. We only used the initial SA and sperm morphology, another potentially important parameter, was not included in the analyses. Importantly, our data might lack the generalizability to other populations. Our results suggest that a TPMC threshold of 50 million sperm provided the best predictive power to estimate earlier time-to-conception in couples evaluated for male sex date and pregnancy calculator infertility. Higher values of sperm count, concentration and progressive motility beyond the WHO references were still associated with better conception rates and time-to-conception. This provides an opportunity to optimize semen parameters in those with semen values that are low but not abnormal according to the WHO reference values. These data can be used to better inform patients regarding their chances of conception per year when SA results are used for patient counseling.

Semen analysis SA is usually the first and often the only test used to evaluate the reproductive function of a male partner in couples seeking infertility counseling Practice Committee of the American Society for Reproductive Medicine, The World Health Organization WHO recommendations are sex date and pregnancy calculator used to interpret SA results World Health Organization, These thresholds, however, do not strongly correlate with fertility outcomes and cannot be reliably used to differentiate fertile from infertile men Nagler, Moreover, several studies have shown an increased probability of pregnancy with semen parameter values well above the WHO reference levels Guzick et al. While the overall ability of semen parameters to differentiate fertile from infertile men remains limited Polansky and Lamb, ; Guzick et al. Thus, longitudinal studies with adequate follow-up time are needed to assess the relations between semen parameters and time-to-conception, rather than conception success. Time to conception is a more clinically meaningful parameter for counseling patients seeking fertility treatment. The concept of total motile sperm count TMCor more accurately total progressive motile sperm count TPMCwas first introduced in the s as a better way to assess the severity of male factor infertility by combining information on semen volume, sperm concentration, and progressive motility Smith et al. Smith et al. Further studies reinforced the idea that TPMC has a better correlation with natural pregnancy rates than other individual semen parameters Small et al. TPMC is also correlated with IUI success and might be useful in selecting patients for IUI over IVF Brasch et al. InHamilton et al. However, the methodology and the evidence underpinning these thresholds remain unclear and population-based data are lacking sex date and pregnancy calculator define the optimal TPMC threshold for fertility prediction. We hypothesized that higher values of semen parameters are associated with higher conception rates and earlier time-to-conception in men undergoing fertility evaluation. We integrated data from the Subfertility Health and Assisted Reproduction and the Environment SHARE study with those from the Utah Population Database UPDB to define the cohort of men undergoing male fertility evaluation. SHARE combines medical, genealogic, and administrative data with biospecimen data to create a unique resource that currently includes the University of Utah and Intermountain Healthcare's SA results collected from to Median income was estimated based on zip code data.
