Do girls release estrogen at ejaculation just as guys release testosterone?

guys release semen and seminal fluid, not testosterone at ejaculation. Testosterone is released from the testes into the blood stream. Ejaculating testosterone will have no practical value for your body or the females body. Females secrete a sexual fluid which is watery with low protein content to act as a lubricant.

The subject of female ejaculation is highly controversial. Female ejaculate is a fluid that is expelled from the body through the urethra during sexual activities. When released in small quantities it may be a mucous like fluid having a clear, milky, or yellowish coloration. As the volume of the expelled fluid increases it becomes like clear water. In small quantities it may have a distinct scent that is musky or pungent but when the fluid increases in volume and becomes clear there is no longer a detectable scent. The fluid contains PSA and PAP, which are produced in the female prostate. Some of the components found in it, urea and creatinine, are also found in urine, but in much lower concentrations than are found in regular urine. When female prostatic fluids are found in urine they are in much smaller concentrations than in present in female ejaculate. The fluid released during ejaculation and urination are not the same though they may share some of the same substances. As the volume and appearance of female ejaculate changes it is likely that its composition changes too. Estrogen is produced in the developing follicles in the ovaries and released into the blood stream
