It is important for couples to maintain open and honest communication with each other, and to recognize that feelings can change over time. For single parents wishing to have additional children, it's also important that they try to develop a strong support system through friends and family. And, because children can pick up on their parents' stress, it is also important to pay attention to how their kids may be feeling. Children might not understand why their parents are feeling a certain way and attribute it to something they've done.  

Fertilization of the oocytes must happen with 12 to 24 hours. Your partner will likely provide a semen sample the same morning you have the retrieval. The stress of the day can make it difficult for some, and so just in case, your partner may provide a semen sample for backup earlier in the cycle, which can be frozen until the day of the retrieval.

The best study in the field enrolled 750 women to receive clomid or letrozole, followed them for 5 courses of therapy and revealed that the group receiving letrozole had higher live birth rates and fewer multiple gestations. The data is of exceptional quality, and there’s no reason to believe the conclusion doesn’t also apply to the choice of drugs if these patients proceeded on to IUI.

In order for pregnancy to happen, sperm has to meet the egg. This normally takes place at the end of the fallopian tube, and this is called fertilization. There are a number of obstacles that can prevent this from happening, and the process itself even in healthy young fertile women is very complex- hence the low pregnancy rate each month. Obstacles such as cycle timing, low sperm count, poor sperm motility, blocked fallopian tubes, or endometriosis must be overcome to achieve a pregnancy. Timing is often the most common obstacle to conception. What does it mean for you when common causes of infertility are ruled out and you’re told you have unexplained infertility? It should mean a time of hope.


Life isn’t fair – there’s no doubt about it. That’s why it helps to have faith in God, to know He loves you and wants you to have the best possible life. My husband and I can’t have children, and it was the most disappointing discovery of my life. Trusting God when you can’t get pregnant is not easy – especially if you’ve been trying to conceive for months or even years.
I had a wonderful experience at CHA Fertility Clinic and got pregnant on my first cycle.  My son will turn two this year and I immediately contacted them when we were thinking of having a second child.  The doctors and staff are so kind, informative, and helpful, and they really put my mind at ease.  We had looked at other fertility clinics … Read More
Sunni Muslim nations generally allow IVF between married couples when conducted with their own respective sperm and eggs, but not with donor eggs from other couples. But Iran, which is Shi'a Muslim, has a more complex scheme. Iran bans sperm donation but allows donation of both fertilised and unfertilised eggs. Fertilised eggs are donated from married couples to other married couples, while unfertilised eggs are donated in the context of mut'ah or temporary marriage to the father.[176]

Another major cause of infertility in women may be the inability to ovulate. Malformation of the eggs themselves may complicate conception. For example, polycystic ovarian syndrome is when the eggs only partially develop within the ovary and there is an excess of male hormones. Some women are infertile because their ovaries do not mature and release eggs. In this case synthetic FSH by injection or Clomid (Clomiphene citrate) via a pill can be given to stimulate follicles to mature in the ovaries.
Amongst these two patient populations (which we’ll refer to now as PCOS), IUI with clomid and letrozole generally shows no improvement versus when these drugs are taken without IUI. When IUI is coupled with gonadotropins, success rates reach 14 - 26% per cycle, which is higher than almost any other patient class, but still pales in comparison to IVF. It’s also worth noting that PCOS patients who are taking gonadotropins have a very high risk of multiples.
Complexity. IUI refers to one procedure. Prepared sperm is placed directly in the patient’s uterus when she is ovulating in order to aid fertilization. IUI may be performed in sync with a woman’s natural cycle or timed with fertility medications to stimulate ovulation. IVF, on the other hand, is a process which consists of several stages and requires more than one procedure: first the ovaries are stimulated using a series of fertility medications, then the patient undergoes egg retrieval in a day procedure under a mild anesthetic, then after embryos have been created and incubated in the lab, they are placed directly into her uterus in the embryo transfer procedure. Even with the use of fertility drugs, going through IUI is less physically demanding than undergoing IVF.
For women, problems with fertilisation arise mainly from either structural problems in the Fallopian tube or uterus or problems releasing eggs. Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue. For example, endometriosis can cause infertility with the growth of endometrial tissue in the Fallopian tubes or around the ovaries. Endometriosis is usually more common in women in their mid-twenties and older, especially when postponed childbirth has taken place.[55]

The Catholic Church opposes all kinds of assisted reproductive technology and artificial contraception, on the grounds that they separate the procreative goal of marital sex from the goal of uniting married couples. The Catholic Church permits the use of a small number of reproductive technologies and contraceptive methods such as natural family planning, which involves charting ovulation times, and allows other forms of reproductive technologies that allow conception to take place from normative sexual intercourse, such as a fertility lubricant. Pope Benedict XVI had publicly re-emphasised the Catholic Church's opposition to in vitro fertilisation, saying that it replaces love between a husband and wife.[127]

In a lab, your eggs are mixed with sperm cells from your partner or a donor — this is called insemination. The eggs and sperm are stored together in a special container, and fertilization happens. For sperm that have lower motility (don’t swim as well), they may be injected directly into the eggs to promote fertilization. As the cells in the fertilized eggs divide and become embryos, people who work at the lab monitor the progress.

A woman's age is a major factor in the success of IVF for any couple. For instance, a woman who is under age 35 and undergoes IVF has a 39.6% chance of having a baby, while a woman over age 40 has an 11.5% chance. However, the CDC recently found that the success rate is increasing in every age group as the techniques are refined and doctors become more experienced.
Infertility is a medical condition, and a fertility specialist can help with thorough, focused examinations directed at discovering the underlying cause. For every couple that begins an evaluation, about 35% discover that there is an issue with the man which is contributing to the couple’s infertility. 50% is related to female factor while 5% is due to rare causes. The remaining 10% (1 in 5 couples) is due to unexplained infertility despite completing a full infertility work-up.(2)
We know this is a touchy subject, but unfortunately, there’s no way around it. Science says that age does play a role in fertility. This 2018 study correlated age as a statistically significant factor in secondary infertility compared to primary infertility. In the study, the average age of couples was higher among those experiencing secondary infertility.
Post transfer – You’ll likely take progesterone and estrogen to improve implantation and pregnancy rates. If the transfer is successful, a blood pregnancy test will be positive in 10-14 days. From there, ultrasounds are used to ensure the implantation site as well as check for a heartbeat. The good news is that once a heartbeat is detected, the pregnancy has a 90-95% probability of the pregnancy resulting in a live birth.
