IUI
INTRAUTERINE INSEMINATION
Intrauterine insemination treatment in Coimbatore is a popular and effective fertility procedure for couples trying to conceive. Intrauterine insemination (IUI) involves placing “washed” sperm directly into the uterus through a catheter. The male partner provides a semen sample through masturbation, and the sperm is carefully separated from the seminal plasma, white blood cells, prostaglandins, and other unwanted substances that are filtered out during natural intercourse.
A tube with a needle attached that contains the cleaned sperm is sent through the cervix and into the uterus during the process, which also involves inserting a speculum into the woman's vagina. The speculum and catheter are taken out, and the "prepared semen" is injected. The possibility of successful fertilization is increased by this entire process.
prerequisites for IUI
- Atleast one tube which is open / patent
- Ovulation by ultrasound scan
- Good sperm count / motility
- Good endometrial lining
Is IUI painful?
The procedure is minimally invasive and may cause slight discomfort, particularly when the catheter is passed through the cervix. Many patients compare the discomfort to that of a Pap smear.
Success with IUI
It is important to note that success may not happen on the first attempt. Most fertility specialists recommend undergoing a few cycles of IUI to increase the chances of pregnancy. In some cases, doing two inseminations back-to-back may further enhance success rates.
How Soon After IUI Can You Get a Pregnancy Test?
To give the fertilization proper time, you should wait two weeks following the surgery before getting a pregnancy test.
What is IVF?
In-vitro fertilization (IVF) is another fertility treatment where sperm and eggs are fused outside the body to create embryos, which are then placed in the uterus. While both IVF and IUI are effective, intrauterine insemination treatment in Coimbatore is often chosen as a less invasive first step in the fertility journey.
When and where are the sperm collected?
Sperm can be collected at home or in the hospital. If collected at home, the sample must reach the hospital or laboratory within an hour. Most fertility centers offering IUI treatment in Coimbatore provide special rooms for semen collection for added privacy and comfort.
Does sperm need to be prepared before IUI?
Yes. Preparation takes approximately an hour. Insemination should occur shortly after the sperm has been prepared.
Process of IUI Treatment
- Semen Collection: The male partner provides a semen sample.
- Semen Analysis: The sperm is evaluated for count and motility.
- Semen Preparation/Wash: The sample is processed to isolate motile sperm and remove unwanted components.
- Post-Preparation Analysis: The prepared semen is analyzed to ensure quality.
- Sample Loading: The washed sperm is loaded into a catheter.
- IUI Procedure: The sperm is introduced into the uterus.
Why semen sample is prepared ?
Preparation enhances the quality of the sperm and improves the chances of conception by:
- To capacitate the sperm and make it hyper motile
- To remove the seminal plasma from sperms which contains prostagladins
- Selection of motile sperms
- To remove lymphocytes, cytokines, infectious substances from the semen sample
- To reduce reactive oxygen species numbers
- To remove non motile sperms
- To process highly viscous sample
IUI
Approximately, natural IUI without medications has the success rate of 6‐10%, while IUI with fertility medications are about 20‐30% successful. Are there any risks associated with IUI? IUI is the least stressful fertility treatment on a woman’s body, especially if the patient is not taking fertility medications. It has a very few associated risks. However, cramping or spotting may occur during or after the procedure.
An IUI — intrauterine insemination — is performed by threading a very thin flexible catheter through the cervix and injecting washed sperm directly into the uterus. The whole process doesn’t take very long — it usually only requires the insertion of a speculum and then the catheter, a process that maybe takes a couple of minutes (60-90 seconds to introduce the catheter, then sperm injection, and another 60 seconds or so to remove the catheter — going slowly helps reduce discomfort). Sometimes when the cervix is hard to reach a tenaculum is used to hold the cervix, which makes the process a bit more uncomfortable. A typical “Tomcat” catheter is shown below.
Usually the sample is collected through ejaculation into a sterile collection cup, but it is also possible to obtain collection condoms for this purpose. Most clinics want the semen to be delivered within a half hour of ejaculation, around the time of liquefaction, so if one lives close enough the sample can be collected at home. If not, one has to make do with a room at the clinic, a bathroom, or any private setting. There is a delay between when the semen sample is dropped off for washing and when it is inseminated. The amount of time depends on the washing technique used, which takes 30 minutes to two hours, as well as on the clinic’s scheduling. Most will perform the IUI as soon after washing is completed as possible.
A: Ideally an IUI should be performed within 6 hours either side of ovulation — for male factor infertility some doctors believe after ovulation is better, otherwise chances of success are higher with insemination before ovulation with the sperm waiting for the egg. When timing is based on an hCG injection, the IUIs are usually done between 24 and 48 hours later. Typical timing would be to have a single IUI at about 36 hours post-hCG, though some do it at 24 hours, and some clinics are reporting better results when doing the IUI at 40-42 hours post-hCG. If two IUIs are scheduled, they are usually spaced at least 12 hours apart between 24 and 48 hours after the hCG. Some reports show no increase in success rates with two IUIs, but others suggest it may increase success as much as 6 percent. Some doctors will base timing of IUI on a natural LH surge. In that case, a single IUI at 36 hours is the norm, but doing them at 24 hours is also pretty common since ovulation may be a bit earlier. When two inseminations are planned, they are usually timed between 12 and 48 hours after the surge is detected. The egg is only viable for a maximum of 24 hours after it is released.
Searching through about a dozen medical journal articles and a number of web sites resulted in a rather wide range of statistics. Basically the odds of success are reported to be just under 6 percent and as high as 26 percent per cycle. The low statistics are with one follicle, while multiple follicles resulted in as high 26 percent success. Another influencing factor is sperm count. Higher sperm counts increase the odds of success; however, there was little difference between success with good-average counts and those with high counts. The overall success rate seems to be between 15-20 percent per cycle, judging from the articles which will be abstracted below. The rate of multiple gestation pregnancies is 23-30 percent.
Most women consider IUI to be fairly painless — along the same lines as having a pap smear. There can be some cramping afterward, but often what is felt is ovulation-related rather than from the IUI. The catheter usually doesn’t feel like much since the cervix is already slightly open for ovulation — a poorly timed IUI might cause more discomfort at the cervix. See the personal experiences below for more details.
Current research indicates that washed sperm can live 24-72 hours; however, it does lose potency after 24 hours. Another issue with IUI is that the sperm can keep on swimming beyond the fallopian tube, so the ideal window is really within 6-12 hours of the egg being released, with a larger margin before ovulation than after since the egg’s viability is shorter. Sperm can live up to 5 days in fertile mucus, 2-3 days being pretty common, so combining IUI with intercourse may provide better coverage.
You don’t have to lay down because the cervix doesn’t remain open, but most doctors let patients lay down on the table for 15-30 minutes after the procedure.
Most people don’t need to, but if you had cramping or don’t feel well afterward it makes sense to take it easy for awhile. Some people reduce their aerobic activity and heavy lifting during the luteal phase in hopes it will increase the chance of implantation. It is more important to take it easy for a bit after IVF, as that is a more invasive process.
This depends on your individual situation, but it usually should not be more than than 72 hours since his last ejaculation in order to ensure the best motility and morphology. Where low sperm count is the reason for IUI, it is generally best to wait 48 hours between ejaculation and collecting sperm for the IUI. With no sperm count issues, it makes sense to wait at least 24 hours. Some suggest trying for about 36 hours to cover the most territory with the highest counts — a common suggestion is to have intercourse around the time of hCG injection.
Usually you can have intercourse anytime after an IUI . . . in fact, most doctors suggest having intercourse, when that is an option, soon after the last IUI to help make sure ovulation is covered. Your doctor may suggest waiting 48 hours to resume relations if you had any bleeding during the IUI or if a tenaculum is used.
Once the sperm is injected into the uterus, it does not fall out. There can, however, be increased wetness after the procedure because of the catheter loosening mucus in the cervix and allowing it to flow out. Some doctors will insert a cup around the cervix to prevent leakage, but most do not.
The catheter loosens cervical mucus and lets it come out more easily. It is common to see more fertile mucus after an IUI for this reason, as well as the fact that well-timed IUI should be close to ovulation.
According to different studies, either 3-4 follicles gives one the best chance of getting pregnant, while more follicles beyond that simply increases the risk of multiples. The U.S. study said 4 follicles, while other countries have data stating 3. The U.S. has a higher rate of multiple births, so 3 may be more likely to be the correct answer.
IUI can help on Clomid cycles where cervical mucus is a problem, and IUI increases the chance of success on injectable cycles no matter what the sperm count. It does make sense to try IUI if you can and haven’t had success with intercourse. It is important to note that with intercourse, only the best and strongest sperm make it through the cervical mucus and up into the uterus and fallopian tubes. With IUI, more sperm will be available for fertilization.
A count above one million washed appears necessary for success, with a significant reduction in pregnancy rates when the inseminated is count is lower than 5-10 million (in other words, in most cases one should consider 5 million a lower limit for success, 10 million for cost-effective). Higher success rates are with washed counts over 20-30 million, while increasing counts over 50 million did not appear to offer advantage. Advanced Fertility has a chart of success rates for one month of various treatments.
It depends on what you can afford and what meds you are doing. One might do 3-4 IUIs on Clomid before moving on to injectables, then do 3-4 cycles on injectables. If one doesn’t have success after four good ovulatory cycles on injectables with well-timed IUI, it would be time to consider IVF.
An IUI shouldn’t be done at home without medical supervision because the sperm needs to be washed to prevent infection — i.e., separated from the semen. A vaginal insemination can be done at home, but is no more successful than intercourse. Some doctors are willing to instruct on doing ICI (intracervical insemination) at home, but it should not be attempted without being taught proper technique. Getting semen or air into the uterus could be quite dangerous — perhaps life-threatening. One woman wrote in to say there is a midwife practice in Berkeley, CA, that will do inseminations at the patient’s home, so it may be worth asking about.
Implantation generally takes place 6-12 days after ovulation — so 6-12 days after a well-timed IUI. See abstract.
This depends on the type of IUI Cycle. Natural cycle costs less. Stimulation cycle costs higher. Stimulation with gonadotropin injection is much costlier with much higher results. Cost of the IUI procedure is approx Rs.3500
This depends mostly on how the female is being treated. A natural cycle is often timed to over the counter ovulation prediction kits, which cost $15-60 for 5-9 tests. The use of clomiphene citrate can increase the monitoring, but many doctors don’t do ultrasounds or settle for one u/s around cycle day 12. Gonadotropins increase both medication costs and the necessity of ultrasounds and bloodwork.
Many doctors monitor follicle development during IUI cycles. Most trigger when the dominant follicle is within a certain size range. While there is always some difference in doctor preference, the norms are unmedicated 20-24mm, clomiphene citrate 20-24mm, FSH-only meds 17 or 18mm minimum, and FSH+LH would be 16 or 17mm minimum. It is possible for slightly smaller follicles, 14-15mm, to contain a viable egg. Also, follicles continue to grow until they release, usually at a rate of about 1-2 mm per day. A woman may ovulate more than one follicle in a cycle, but the releases will occur within 24 hours. When hCG is not used, only follicles close in size are likely to release. The use of hCG induces ovulation in about 95 percent of women, and will get most mature follicles to rupture.
The E2 level should be 200-600pg/ml per 18mm follicle. Some doctors are content with a minimum level of 150, but higher tends to be better.
The main risks are some discomfort such as cramping, minor injury to the cervix that leads to bleeding or spotting, or introduction of infection (including sexually transmitted disease from the sperm itself — it helps to be sure of the known donor’s health, or use carefully monitored frozen specimens). There are also risks of hyperstimulation associated with the use of ovulation induction medications such as clomiphene citrate (low risk) and gonadotropin therapy (higher risk). Proper technique and adequate monitoring reduce risks.
Most women don’t need medication for pain associated with IUI. If there is cramping, it is best to avoid medications such as ibuprofen and naproxen (NSAIDS), but Tylenol is considered safe (but maybe not that helpful for cramps).
It is sometimes also called sperm preparation or spinning. It is a laboratory technique for separating sperm from semen, and separating motile sperm from non-motile sperm, for use in assisted reproduction (IUI, IVF). The washing technique for near normal specimens is mixing the ejaculate after liquefaction with the appropriate washing medium followed by centrifugation. (A centrifuge is a machine that separates materials with different densities by spinning them at high speed.) The supernatant is discarded and the sediment (sperm rich fraction) is re-suspended in more washing medium. This process is repeated 2-3 times maximum. In the final wash, the sediment is re-suspended in 0.5 cc of medium, loaded into a syringe and deposited in the uterus. The “Sperm Rise” or “Swim-up” technique is one in which two to five cc of medium are carefully layered on top of 0.2-0.5 cc of semen. Motile sperm cells “swim-up” into the culture medium. After some time (30-90 minutes) the medium (containing motile sperm cells) is carefully harvested and centrifuged. If necessary, fresh medium is layered on top of the seminal fluid again to harvest more sperm cells. The discontinuous gradient centrifugation technique utilizes a dense liquid phase to separate sperm cells from seminal fluid and debris. There are different compounds commercially available that may be used. Semen is deposited on top of this fluid and subjected to centrifugation. Motile sperm cells migrate to the bottom of the tube, which are used for IUI after further washing.
Since the vagina doesn’t open unless something pushes it, it is OK to swim shortly after your IUI . . . but because of how much one has invested in getting pregnant, it probably makes sense to wait 48 hours after your IUIs to go swimming.
No. A tubal ligation is effective birth control because it prevents the sperm and egg from meeting. The process that leads to pregnancy is having an egg released from a follicle in the ovary and then beginning the journey to the uterus through the fallopian tube. Sperm will travel from the vagina, through the cervix, through the uterus, into the tube where fertilization occurs. IUI bypasses the need for the sperm to travel through the cervix, but that’s it. It doesn’t get the egg to the other side of the obstruction, so fertilization won’t take place. The only way to get pregnant after tubal ligation is by having reversal surgery or an assisted reproduction technology that includes egg retrieval, such as in vitro fertilization (IVF).
