Frequently asked questions

  • What is the FertiLily conception cup?

    A hormone-free conception aid, the FertiLily conception cup is clinically proven to increase the chance of pregnancy by 48%.¹ With its soft silicone construction, the cup is easy to insert into the vagina after intercourse. It’s designed to push the sperm towards the cervix, as the more sperm reach the protective cervical mucus the more sperm can survive for longer and swim towards the egg in the uterus.

    This increases your chance of getting pregnant when you are trying for a baby by one and a half times.

  • How can the FertiLily help when trying to conceive? 

    Conception cups place the sperm cells closer to the cervix after intercourse which increases the amount of sperm cells reaching the cervix. The cups shorten the distance the sperm needs to travel to enter the cervix and helps to protect them from the  hostile pH of the vagina. 

    Studies have shown that using a cervical cup after intercourse can increase the amount of sperm cells that swim into the cervical mucus by more than 300%.²  

    FertiLily has been clinically proven to increase the chances of conception by over 48%¹- great news if you are trying to get pregnant.  

  • How do I know if the cup is in the right position? 

    The conception cup needs to be at the top of the cervix which is located at the top of the vagina. When inserting the cup, you should feel resistance (like pushing the tip of your nose), this means it’s in the right position.  

    You can feel with your finger if the cup is inserted correctly. You can check the position by feeling for the two indents on either side of the stem, these can only be felt when the cup is in its original shape. You can also make small adjustments to the position of cup using the stem. 

    Before you need to use the cup, practise inserting and removing it so you can get used to the way it feels  in both its original shape and as an ‘umbrella’. 86% of women found FertiLily cup easy to use, and 9/10 found it comfortable to wear when trying to conceive.*** 

  • How do I remove the FertiLily conception cup? 

    Removing the FertiLily cup after intercourse isn’t usually uncomfortable as the vagina is well lubricated and larger than normal. If you’re having trouble take a few deep breaths and try folding it like a menstrual cup or use the notches on the cup to squeeze it together. This will make the cup smaller.  

  • How long can I use the FertiLily? 

    The FertiLily Conception Cup can be used up to 18 times or up to six cycles (roughly three times per cycle).  

    You should stop using your cup and replace it if you notice: 

    • A tear 
    • Unusual odour 
    • Discolouring 
    • Any signs of deterioration or damage 

     A cup in poor condition can cause irritation and can break or may even harm sperm.  

  • Can the FertiLily cup get lost inside me? 

    The FertiLily Conception Cup cannot get lost inside you, as the vagina is not directly connected (internally) to any other part of the body. Used correctly, the cup is easy to insert and remove. It has an elasticated stem that helps you find the cup to pull it out, so it is highly unlikely that it will get stuck inside you. 

  • Why is there still liquid in the FertiLily cup when it is removed? 

    Sperm consists of only 2-5% sperm cells. The rest is a combination of excess fluids including amino acids, enzymes and fluids excreted by the male genitalia, therefore, it is quite normal for liquids to remain after removing the cup and nothing to worry about. Without a cup, this gradually flows out, or, for example, when you go to the toilet. The liquids you find in the FertiLily Conception Cup are exactly the same - they simply come together in one place and removed in one go. 

    Sperm contains the important sperm cells necessary for fertilisation and immediately after ejaculation, they will try to swim to the cervix. The FertiLily Conception Cup gives the sperm a push and places them as close to the cervix as possible. Most sperm will reach the cervical mucus 20-60 minutes after insertion of the cup. 

    Although not all sperm will be pushed through the cup, it is also not the case that the sperm cells that have reached the cervix are pulled out again during the removal of the cup. 

  • What happens if I forget to remove the FertiLily? 

    Firstly, don't panic, as the cup is made of body-safe medical grade silicone, similar to menstrual cups. If you find that you’ve had the cup inserted for more than an hour, remove the cup before rinsing and patting dry.  

  • How does the FertiLily differ from just using a menstrual cup? 

    Simply put the FertiLily cup is used to increase the chances of conception when trying to make a baby whereas menstrual cups are used during your periods to collect blood and prevent leakage. The cups are made and tested for these different purposes. The conception cup is a medical device which has been tested for safety and efficacy in helping women to get pregnant. 

    Although the cups may look similar, a menstrual cup is designed for - and tested for - a completely different purpose. A menstrual cup sits just inside the vagina. It is simply meant to collect blood and prevent leakage. The FertiLily Conception Cup performs the more active function of not only collecting sperm and preventing leakage but, by sitting deeper within the vagina, it brings the sperm closer to where it needs to go and protects it from the sperm-hostile environment of the vagina.

  • Why should I use FertiLily conception gel when trying to conceive? 

    When trying to conceive, up to twice as many women experience vaginal dryness compared to the general population.⁴ When trying for a baby intercourse tends to be more planned which may mean you’re not always in the mood and so experience dryness.  

    FertiLily conception gel provides extra lubrication during intercourse without having negative effects on sperm. FertiLily Conception Gel is sperm friendly and doesn’t include ingredients such as glycerine or preservatives. It helps to keep trying for a baby comfortable and fun, as it should be.
