    Retrograde ejaculation occurs when semen enters the bladder instead of emerging through the penis during orgasm. Although you still reach sexual climax, you might ejaculate very little or no semen. This is sometimes called a dry orgasm. Retrograde ejaculation isn't harmful, but it can cause male infertility. Treatment for retrograde ejaculation is generally only needed to restore fertility.

Human female orgasm is a vexed question in the field while there is credible evidence of cryptic female choice that has many hallmarks of orgasm in other species. Our initial goal was to produce a proof of concept for allowing females to study an aspect of infertility in a home setting, specifically by aligning the study of human infertility and increased fertility with the study of other mammalian fertility.

    A dry orgasm can occur as a result of surgery to remove the prostate gland and surrounding lymph nodes radical prostatectomy or surgery to remove the bladder cystectomy. After either of these procedures, you no longer produce semen. Dry orgasm can occur after some surgeries for testicular cancer, such as retroperitoneal lymph node dissection, which can affect the nerves that control orgasm. In some cases of dry orgasm, semen is produced but goes into the bladder instead of out through the penis during sexual climax.
