SPERM RETRIEVAL PROCEDURES (PESA, MESA, TESA, TESE)
In few people, spermatozoa may not be available in the discharge. This condition is called Azoospermia. This can be either because of issues in sperm creation itself or because of obstacles in the flow of semen during the ejaculation or discharge. Reproductive tract obstruction can occur because of disease, injury, iatrogenic damage which can happen during the pelvic, bladder neck, stomach or inguinal-scrotal surgery.
Intrinsic anomalies might be moderately uncommon in the normal population, yet it can happen in up to 2 percent of barren men. The best-known condition is a congenital bilateral absence of the vas deferens (CBAVD) which happens in all men with cystic fibrosis.
Two processes – Epidydima sperm recovery and micromanipulation have brought a positive revolution in the treatment of infertility in men, in the previous decade. Men with an inborn bilateral absence of the vas deferens (CBAVD) or regenerative tract obstruction can accomplish pregnancies by the utilization of these advanced techniques.
PESA or Percutaneous Epididymal Sperm Aspiration (PESA), does not require a surgical cut. A little needle is passed straight in the head of the epididymis through the scrotal skin and liquid is suctioned. The embryologist recovers the sperm cells from the liquid and sets them up for ICSI.
Microsurgical Epidydimal Sperm Aspiration (MESA) is executed as a part of conditions like obstructive azoospermia. It includes dissection of the epididymis under the working magnifying lens and incision of one tubule. Liquid spills from the Epidydimal tubule and accumulates in the Epidydimal bed. This pooled liquid is then suctioned. Since the epididymis is luxuriously vascularized, this technique does lead to contamination of blood cells and may limit the fertilizing ability of sperm during the process of in-vitro fertilization.
TESA and TESE
TESE or testicular sperm extraction is a surgical biopsy of the testis as compared to TESA or testicular sperm aspiration which is executed by putting in a needle inside the testicles and then suctioning liquid and tissue via negative pressure. The suctioned tissue will then be handled in the embryology research facility and the sperm cells that are extracted are utilized for ICSI.
A testicular biopsy is a test to extract a little sample of tissue from one or both the testicles. The tissue is then examined under a magnifying lens to check whether the man can father a child or not. The gonads (testicles) are oval-shaped organs that hang in the scrotum under the base of the penis. The testicles deliver sperm (which is required for reproduction) and male hormones, for example, testosterone.
Why It Is Done
A testicular biopsy might be done to help discover the reason for male infertility. Be that as it may, this is uncommon. It can also be done if both of the following points are valid:
- The man’s semen does not have sperm.
- Hormone test results are not inside the typical range.
This test isn’t generally used to discover testicular growth. On the off chance that your specialist suggests that you may have cancer, you will most likely have an open surgical method called an orchiectomy. A testicular biopsy may likewise be done to get sperm for an in-vitro treatment for intracytoplasmic sperm infusion (IVF-ICSI).
How It Is Done
This test is finished by a surgeon or a doctor who specializes in treating fertility issues in men (urologist). It should be possible in the office of the doctor, a day surgery center, or an operating room of the hospital. You are asked to lie on your back on an exam table. The skin over your gonad is cleaned with a sterile liquid. The region around it is secured with sterile material. Your specialist will wear gloves. It is vital that you don’t touch this region. A local analgesic will be infused into the skin of the scrotum to numb the area. At that point, a little incision is made into the skin. A very small piece of testicular tissue is extracted with little scissors. With the help of a single stitch, the cut on the testicle is closed (The stitches need not be removed. It will be absorbed by the body after some time. The technique is typically executed on the other gonad too. The scrotal zone is then bandaged. You may have to wear an athletic supporter for several days after this test. You will be approached to wear a jockstrap for a few days after the test. This will assist the testicles during the healing period.
If general anesthesia is utilized, you will be sleeping in between the entire process but the rest of the operation is same as before.
The biopsy, for the most part, takes 15 to 20 minutes. You will likely be encouraged to not have a sexual act for 1 to 2 weeks after the test. Refrain from washing the region for a few days.
The most effective method to Prepare:
Before a testicular biopsy, make sure to tell your specialist in the event that you:
- Have had any bleeding problems.
- Are oversensitive to any medications, including soporifics.
- Are taking any prescriptions frequently. Make certain to enlighten your specialist regarding every one of the prescriptions you take, even over-the-counter ones.
- Take any blood-diminishing medications, for example, warfarin (Coumadin), heparin, enoxaparin (Lovenox), headache medicine, ibuprofen, or different NSAIDs.
You will be made a request to sign a consent form that says you are aware of the dangers of the test and are willing to have it done.
Converse with your doctor about any worries you have regarding the requirement for the test. Get some information about its dangers, how it will be done, and what are the outcomes that can be expected. In the case that the biopsy is done under local anesthesia, you don’t have to do anything else to prepare.
In the event that the biopsy is done under general anesthesia, your specialist will disclose to you how soon before surgery to quit eating and drinking. Follow the guidelines precisely, or your surgery might be canceled. In the event that your specialist has instructed you to take your medications upon the arrival of surgery, kindly do it with the help of just a sip of water. Prior to the test, an intravenous line (IV) is embedded in your arm. You will get a soothing pharmaceutical around an hour prior to the test.

Ultrasound – Scrotum
Ultrasound imaging is the primary method used to help evaluate disorders of the testicles, epididymis (a tube immediately next to a testicle that collects sperm) and scrotum. The procedure involves using sound waves to generate pictures of a man’s testicles and surrounding tissues. Ultrasound is a non-invasive, safe procedure that does not include the use of ionizing radiation.
This procedure does not need any special preparation. Just don’t wear any jewelry and come in comfortable clothing. You might have to wear a gown.
What is Ultrasound Imaging of the Scrotum?
Ultrasound imaging of the scrotum is the imaging technique used to assess problems of the balls, epididymis (a tube right beside a testicle that gathers sperm made by the gonad) and the scrotum.
This investigation is commonly used to:
- check if a mass in the scrotum, that may be felt by the patient or specialist, is strong or cystic and its area.
- diagnose consequences of any injury to the scrotal region.
- diagnose reasons for testicular agony or swelling, for example, irritation or torsion.
- diagnose the reason for infertility, for example, varicocele.
- look for the location of the undescended testis.
A sudden beginning of pain in the scrotum area ought to be considered important. The most widely recognized reason for pain in the scrotal area is epididymitis, which is an inflammation of the epididymis. Antibiotics can treat this problem very easily. In the event that it is left untreated, this problem can prompt a sore or loss of blood flow to the testicles.
Ultrasound can frequently detect a missing or undescended testicle too. It is assessed that around three percent of full-term baby boys have undescended gonads. Normally, the testicle starts moving from the abdomen, the inguinal canal and after that into the typical position in the scrotal sac. If not present in the scrotal sac, the gonad may have stopped while coming down and may lie in the inguinal region, in which case the ultrasound examination will observe it in most cases. In the event that the testicle is still in the stomach cavity, it might not be visible via sonography. On the off chance that a gonad isn’t identified, a urologist will analyze whether any other technique like MRI is needed to detect it or not. If the gonad is observed to be in the inguinal region, it can be moved into the scrotum. On the off chance that it is left in the stomach area too long, it might end up being cancerous and should be expelled.
Ultrasound can distinguish testicular torsion from the bending of the spermatic cord that has the vessels that provide blood to the gonad. Because of abnormally and loosely attached tissues that are created at the time of fetal development, torsion normally shows up at the time of puberty, and less regularly in the neonatal period, and is exceptionally excruciating. Torsion demands prompt surgery to keep away from permanent damage to your testes.
Additionally, ultrasound can be utilized to find and assess masses (irregularities or tumors) in the testes or somewhere else in the scrotum. Accumulations of liquid and irregularities of the veins may show up as masses and can be evaluated by ultrasound. Masses both outside and inside the gonads might be benevolent or threatening and ought to be assessed when they are recognized.
How can a patient prepare?
You should wear comfy, loose-in-fitting apparel for your ultrasound exam. Your Jewelry or clothes may be asked to be put away. You may need to expel all attire and adornments in the area for inspection. You might be made a request to wear an outfit at the time of the procedure. No other special preparation is needed.
What does the hardware look like?
Ultrasound scanners comprise of a console that contains a PC and hardware, a video screen and a transducer that is utilized to take care of the filtering. The transducer is a little hand-held gadget that looks like a microphone, appended to the scanner by a string. A few exams may need multiple different transducers (with various abilities) during the same exam. The transducer conveys high-frequency sound waves (that the human ear can’t hear) into the body and afterward listens to the returning echoes from the tissues in the body. The working mechanism is similar to the way sonar utilized by water boats and submarines.
The ultrasound picture can be immediately seen on a video show screen that looks like a PC or TV screen. A small quantity of gel is put on the skin to enable the sound waves to set out from the transducer to the inspected region inside the body and after that comeback. For some areas, Ultrasound is an amazing methodology to find problems while in some other areas, particularly air-filled lungs, are ineffectively suited for an ultrasound.
Normally, a linear small transducer is used to perform a scrotal sonogram.
How does the device function?
A sound wave when strikes an object, get reflected or creates an echo. These waves are then analyzed and via that the object’s size, shape and consistency are determined.
In medical applications, ultrasound is utilized to distinguish changes in appearance, size or form of organs, tissues, and vessels or to identify unusual masses, for example, tumors.
At the point when the transducer is squeezed against the skin, it sends little pulses of indistinct, high-recurrence sound waves into the body. As the sound waves skip off inside organs, liquids and tissues, the sensitive recipient of the transducer record small changes in the sound’s pitch and direction. These images, when measured create up the image which is then reflected on the computer, which then makes a continuous picture on the screen.
How is the method performed?
For most ultrasound exams, you will be asked to lie down face-up on an examination table that can be tilted or moved. Patients might be moved to either side to enhance the nature of the pictures.
After you are made to lie down on the examination table, the radiologist (a doctor particularly prepared to conduct radiology examinations) or sonographer will apply a warm water-based gel to that area of the body being which is under study. The gel will then enable the transducer to have a proper contact with the body and dispense the air pockets between the transducer and the skin, which can obstruct the sound waves from going into your body. The transducer is to be put on the body and moved forward and backward properly on the area under inspection until coveted pictures are caught.
There is normally no distress from weight as the transducer is squeezed against the zone while conducting the analysis. Be that as it may, if checking is performed over a zone of delicacy, you may feel the weight or minor agony from the transducer.
Once the imaging is finished, the leftover ultrasound gel will be wiped off your skin. Any bits that are not wiped off, will dry rapidly. The ultrasound gel does not normally stain apparel.
What can be experienced before or after the procedure is executed?
Ultrasound examinations are easy and effectively endured by most of the patients. Ultrasound imaging of the scrotum is normally finished within 15 to 30 minutes, however here and there additional time might be needed. At the point when the examination is finished, you might be made a request to dress and wait while the ultrasound pictures are looked into and examined. After an ultrasound examination, generally, you ought to have the capacity to continue your ordinary exercises promptly.
Who deciphers the outcomes and how would I get them?
A radiologist, a doctor particularly prepared to oversee and decipher radiology examinations, will investigate the pictures and send his feedback to your essential care doctor. More often than not, that doctor or medicinal services supplier will read out the outcomes to you. In some cases, the radiologist may talk about outcomes with you once the examination is finished.
Follow-up examinations might be essential. Your specialist will clarify the correct reason behind why a second examination is needed. In some cases, a subsequent examination is done to ensure that any changes in the discovered condition can be closely regulated. Follow up assessment is an ideal approach to check whether a particular treatment is doing its job on the patient or not, or whether the finding has stayed the same or has changed over time.
Advantages versus risks
- Most of the ultrasound examinations are noninvasive (no needles or infusions).
- In some cases, an ultrasound may be uncomfortable, but it should not cause pain.
- Ultrasound is simple to use, commonly available than other imaging procedures.
- Ultrasound imaging is safe to a great extent and does not utilize any ionizing radiation (like X-Ray).
- Ultrasound examining gives a reasonable picture of delicate tissues that don’t appear well on x-beam pictures.
- Ultrasound delivers real-time images which makes it an excellent tool that can be used for guiding some minimally invasive procedures like needle biopsies and fluid aspiration.
- For standard demonstrative ultrasound, there are no known unsafe consequences for people.
What are the restrictions of Scrotal Ultrasound Imaging?
Ultrasound of the scrotum is useful for discovering anomalies, for example, masses in the scrotum or balls. But, it’s not completely accurate each and every time (i.e., the accurate point out of tissue that a mass is made out of, particularly when the mass is strong). Bloodstream pictures of the gonads are not generally dependable in determining whether blood supply is there or not. While hunting down a missing gonad, ultrasound will most likely be unable to discover it if it’s in the abdominal region. Because the gas-filled loops of bowel may hinder the view.
In the event that you and your partner are experiencing difficulty getting pregnant, most likely you need to discover the reason behind what’s keeping you from becoming pregnant.
While both women and men can have infertility related issues, the impact of male-related issues is existent in almost half of all cases related to infertility. Furthermore, since male infertility is frequently caused by low sperm creation, one of the main tests your specialist will probably request is a semen analysis.
Giving a Semen Sample
In order to run a semen analysis, your specialist will request that you give a semen test. Ordinarily, you discharge into a gathering container in a private room at your specialist’s office.
Sometimes, you can gather your specimen at home, however, you need to keep it at room temperature and get it to your specialist or lab within the timeframe of 60 minutes. A few specialists can furnish you with a special condom that gathers your semen while having sex.
Your specialist may request that you not have intercourse or masturbate for 2 to 5 days before this test to ensure your sperm count is as high as it can be. Be that as it may, don’t stay away from ejaculation for more than 2 weeks before your test. That can result in a specimen with sperm that is less mobile or active.
It’s best not to drink liquor before your semen investigation. You ought to likewise inform your specialist about any prescriptions or home-grown supplements you’re taking. Also, don’t utilize lubricants when you gather your specimen since they can influence how effectively your sperm can move around.
To get the most exact outcomes, your specialist will presumably need to test more than one specimen. You may even need to give 2 to 3 tests over a three-month time frame.
What the Test Tells You
Once a lab gets your semen test, they’ll take a gander at it under a magnifying instrument. This will give them a lot of information which can include:
How many sperms are present. An ordinary sperm tally is between 15 million and 200 million sperm for every milliliter of semen. Your sperm tally is called to be low if you have under 15 million sperm for each milliliter.
What is Sperm Analysis
How your sperm is moving (motility): Your specialist will examine what number of sperm are moving and how well they move. Preferably, half or more than half of your sperm (in the sample) ought to be mobile and active.
What your sperm looks like (morphology): The size and state of your sperm influences their capacity to fertilize an egg. Typical semen will have no less than 30% normal looking sperm.
The doctor will also find other details from the sample like:
Volume: He’ll take note of how much semen you could accommodate while giving the specimen. A typical sum is around 2.5 milliliters, or about a large portion of a teaspoon. In the event that your specimen is not as much as that, it could imply that your original vesicles aren’t making enough liquid or are blocked. You could likewise have an issue with your prostate.
Chemical Composition: Your pH level analyzes the acidity in your semen. Typical pH is in the vicinity of 7.1 and 8.0. A low pH level means you have acidic semen. A high pH level means it’s antacid. An abnormal pH can influence the soundness or health of your sperm and how well it moves.
Liquefaction time: Ordinary semen turns out the thick white discharge. Liquefaction time measures to how much time it takes before it ends up being noticeably fluid. If this doesn’t happen or the sample doesn’t liquify at all, then it might indicate a problem.
Fructose level: On the off chance that your specialist doesn’t discover any sperm in your semen examination, he will most likely check it for seminal fructose, which is created by the seminal vesicles. Low levels, or no fructose, could mean you have some kind of an obstruction.
In the event that the semen analysis does yield problems, the doctor will give out some more tests to find specific issues.
Therapeutic Fertility Preservation for Men
In the event that you need treatment for cancer, that can impact your ability to stay fertile, there are some alternatives that can make sure that you can still be a parent in the future.
Chemotherapy and radiotherapy can influence your sperm generation – in some cases this influence can be brief while in some other it can be non-reversible. Once your treatment starts, it’s fairly possible that the damage might be incorporated in your genes and may cause hereditary harm. Keeping these things in mind, we strongly advise you to contact the andrology unit of a medical facility before starting any disease treatment.
Before you start chemotherapy or radiotherapy treatment, some of your semen, that contains your sperm, can be frozen and kept so that when you want to start a family, you can. Men who need to travel abroad or work in risky circumstances may likewise need to have their sperm solidified for use later on.
How does sperm freezing work?
Sperm samples are collected in a private room and then the scientists do the preparation and freeze them as soon as possible. You can also accumulate it at home and bring it in the lab as soon as possible or you can use a special condom and collect the sperm while having sex. If for some reason you are not able to gather your semen or there are no sperms in your semen, because of any disease, then the doctor might use a needle and collect the sperms from your testicles itself. This process is known as testicular biopsy. It can then later on be used for ICSI treatment.
Once the sperm is gathered, it is blended with a protective solution and then the temperature is bit by bit lessened. Around 25%-half of the sperm will survive the freezing process, and they can be put away for multiple years. The pricing involves an initial freezing fee and then a yearly fee (normally billed every six months) for storing the sperm.
