734
According to the World Health Organization guidelines, ejaculatory abstinence EA of 2—7 days is recommended for semen analysis. This study aimed to determine how seminal quality may be affected by two EA periods from the same man. The semen was qualitatively analyzed by examining oxidative activity intracellular and seminal plasma , sperm function acrosome integrity, mitochondrial activity, and nuclear DNA integrity , and epididymal function. As expected, samples collected after 1 day of EA showed a decrease in volume and sperm total number compared to samples collected after 4 days of EA. The sperm motility of the samples collected after 1 day of EA was better compared to samples collected after 4 days of EA.

Doubts About Intrauterine Insemination (IUI) | IUI Infertility Treatment

Sperm is usually provided the morning of the egg retrieval. Occasionally the sperm is collected ahead of time and frozen for use after the egg retrieval. We can obtain sperm from the male partner through normal ejaculation or through more advanced sperm retrieval procedures such as microepididymal sperm aspiration MESA , or testicular sperm extraction TESE. If your partner will be providing a semen specimen on the day of the egg retrieval, we recommend abstaining from intercourse for at least two days prior to the IVF procedure but not more than 6 days.
