• As mentioned earlier, if no fertilization takes place after ovulation, the endometrium becomes thin by sloughing off and is then discharged through the vagina. (womanjunction.com)
• These two are related since normally, after ovulation and in the absence of fertilization, menstruation occurs. (womanjunction.com)
• Consistency of mucus at the time of ovulation can be checked by collecting some mucus between two fingers and stretching it apart. (infertility-center-madurai.com)
• Implants for birth control may be placed in the arms, releasing progestin, which prevents ovulation and changes the cervical mucus, making it harder for the sperm to reach the egg. (healthcanal.com)

Intrauterine4

• However, cervical mucus might negatively impact the success rates of intrauterine insemination (IUI) or in vitro fertilization (IVF) treatments. (springer.com)
• Cervical mucus can contaminate the intrauterine environment because mucus stuck to the transfer catheter may carry microorganisms into the uterine cavity and intervene with implantation. (springer.com)
• For women with anti-sperm antibodies in their cervical mucus or "poor" mucus and for men with mild male factor infertility, intrauterine insemination (IUI) is a common first-line fertility treatment where washed and concentrated sperm are placed directly into the uterus to maximize the chances of fertilization.

Cervical mucus thicker1

• The hormonal IUD prevents pregnancy by releasing progestin (the hormone found in birth control pills), which makes the cervical mucus thicker and harder for sperm to penetrate. (grafxemporium.com)

Thicker cervical mucus2

• This ensures that even if a sperm was able to get through the thicker cervical mucus and fertilize and egg, it's unlikely that the egg would be able to plant itself and grow in the uterus. (canadapharmacy.com)

• Hormones regulate the immune system throughout the female reproductive tract in a way that favors conditions for sperm migration, fertilization, implantation, and pregnancy [ 16 , 17 ]. (hindawi.com)
• Conversely, if a sperm is able to fertilize the egg, it stays in the fallopian tube between three and four days but within 24 hours of fertilization, the egg divides into several cells, attaches itself to the lining of the uterus via a process known as implantation on the 5th day of fertilization. (womanjunction.com)
• It is important to note that not every woman has an implantation bleed, and it is not always associated with bloody cervical mucus. (daysy.me)

Occurs6

• Fertilization usually occurs in the fallopian tube, and the fertilized egg takes about three days to travel to the uterus and implant itself in the uterine lining. (afraidtoask.com)
