How Mosie Works

Changing the insemination variable can play a meaningful part in trying to conceive! If intercourse isn't working or isn't an option - try Mosie Baby, the first FDA Cleared at-home intravaginal insemination kit. Each kit includes 2 Mosie syringes, with patented slit openings designed specifically for transferring sperm, and 2 Mosie collection cups.

Mosie is designed to be both comfortable and easy to use, and has helped over 100,000 families inseminate from the privacy of their own home.

How to use your Mosie Kit

Collect a semen sample in the provided collection cup. Hint: Aim for the center. Keep this sample at room temperature. Next, wash your hands. This isn’t necessary for conception, it’s just good hygiene.

Dip the end of the Mosie syringe into the collection cup and slowly pull plunger to draw the sample into the syringe.

*Quick Tip: Prior to using the Mosie syringe, pull it back and forth a few times. This will help you get comfortable with it. Be sure to push the plunger all the way to the top before transferring any sperm to the syringe to get any remaining air out.

Get horizontal and comfortable. If possible, use pillows to raise your hips and legs slightly higher than your waist. Insert the Mosie syringe into your vagina just like you would a tampon — up to, but no further than, the handles. (They are actually called a “flange,” which is fun to say). Fully push the plunger to release the sample. Gently remove the syringe immediately after the sample has been transferred.

Dispose of the used syringe.

You’ll need to continue laying down for 15–30 minutes. We recommend listening to music, reading, napping, or saying “flange” over and over. Discard syringe and cup after use. Use second syringe and cup within 18-24 hours.

Timing it Right
We would suggest using Mosie at the very first sign of ovulation, usually about two to three days before the actual ovulation will occur. Then use the next Mosie syringe 18 to 36 hours after that.

You want to make sure you try to conceive prior to ovulation occurring. It takes time for the sperm to swim through your body all the way up to where the egg is released. When the egg is released from your Fallopian tube you want those little swimmers already there and waiting.
