Whether you’re trying to get pregnant or trying not to get pregnant, understanding how our bodies work can be hella confusing. Occasionally things that seem obvious can be so wrong (no, a penis cannot touch the baby’s head while having sex) while other times, it turns out carrying a small human can have some bizarre symptoms.

So, on that subject, it’s probably worth knowing that having sex twice in one night may, in fact, increase your chances of getting pregnant.

The results, published in the journal Molecular & Cellular Proteomics, also found that using sperm produced no more than 180 minutes after a man last climaxed could boost IVF success rates.

During the study, researchers at the hospital tested 500 couples who were preparing for IVF. The men were asked to give semen samples at different times after their first ejaculation.

The embryos were implanted into the women, with the results showing that those who had ejaculated within hours of the first time were more likely to fall pregnant.
