Figure 3.

Figure 3A is a bar graph with standard errors of mean plotting number of entries of sexually receptive females (y-axis) for the Veh and 0.5, 5, and 50 micrograms per kilogram per day DEHP exposure groups. Figure 3B is a bar graph with standard errors of mean plotting percentage of time spent in investigation (y-axis) for the Veh and 0.5, 5, and 50 micrograms per kilogram per day DEHP exposure groups. Figure 3C is a bar graph with standard errors of mean plotting latency to investigation in minutes (y-axis) for the Veh and 0.5, 5, and 50 micrograms per kilogram per day DEHP exposure groups. Figure 3D is a bar graph with standard errors of mean plotting latencies in minutes (y-axis) to first intromission and ejaculation for the Veh and 0.5, 5, and 50 micrograms per kilogram per day DEHP exposure groups.

Effects of di(2-ethylhexyl) phthalate (DEHP) treatment on female interest in males and latency to intromission and ejaculation. (A–B) The partner preference test was performed in a three-chamber paradigm. (A) The number of entries of sexually receptive females into the chamber of the vehicle (Veh) vs. the chamber of the DEHP-exposed male. (B) The percentage of time spent investigating the vehicle (Veh) vs. the DEHP-exposed male. Data are expressed as the means ±SEM of 11–12 males per treatment group, *p<0.05 vs. the vehicle male. (C–D) In the mating test, one-way analysis of variance (ANOVA) showed no effect of DEHP treatment on the latency to the first anogenital chemoinvestigation towards sexually receptive females (C), but an effect (#) on the latencies to first intromission and ejaculation (D). Data are expressed as the means ±SEM of 11–12 males per treatment.
