Andrology and Fertility Laboratory - LABCER- LABCER is a fertility specialized laboratory. It is strategically located within the same facilities of CER in order to make it easier for couples to access a range of specialized laboratory tests and services needed to carry out fertility diagnosis and treatments. Additionally, it has all the conventional laboratory tests available. Laboratory Specialized in Female Fertility Diagnosis. The laboratory tests to determine female fertility revolve around the hormone levels. In Labcer hormones such as FSH, Estradiol (E2) and LH are routinely performed under very strict quality controls. More specialized tests are also done, such as: Anti-Mullerian Hormone (AMH): Women are born with a determined amount of eggs that can be produced (ovarian reserve). The AMH determines very accurately the ovarian reserve of a woman and can be done at any day of the cycle. It is a very useful tool to choose a treatment and predict the response to the medication for ovarian stimulation. Since it is a relatively new test, its availability is limited in some countries. LABCER has this test available in Guatemala since 2006; referring it at first to a laboratory in United States, and since 2012 doing it locally in our lab. ERA, Endometrial Receptivity Array: The endometrial receptivity is the state in which the endometrium (the inner layer of the uterus) is prepared and ready to implant a fertilized egg. This happens between day 19 and 21 of the woman’s menstrual cycle. When there have been recurring failures in the implantation, the ERA is used to evaluate, molecularly, the endometrial factor. It is done by taking an endometrial sample in a determined day of the cycle, and sent to a laboratory in United States, for the analysis of 238 genes. Resulting from this analysis, the endometrium is classified as receptive or unreceptive. This test helps determine the window for implantation of a patient, which can increase the possibilities of a successful embryo transfer.
Ultrasound tests have always been very exciting for future parents wishing to see their baby. Currently there are several types of ultrasound types of ultrasound and more and more families using this alternative to bond with their children before they are born. 4D Ultrasound offers a tremendously clear image of the baby allowing them to see the different features of the baby.
  • 2D Ultrasound: The 2D Ultrasound is the traditional one and the one that has been used by obstetricians for over 4 decades and its safety has been widely established. This kind of ultrasound is used in all areas in CER, aiding in diagnosis and treatment of subfertility and eventually the pregnancy follow up. Its use is essential for providing prenatal monitoring, following growth of the baby as well as its structures. This ultrasound works by interpreting sound waves that are reflected in shaping the image of the fetus. In 2D ultrasound, you can only "see" a single image plane.
  • 3D Ultrasound: The 3D Ultrasound uses a technology known as: surface representation. The (acoustic) sound waves are sent in different angles; additionally sophisticated software is used to interpret these reflections, resulting in a static 3D image of the baby, which means you can see “depth” in the image, as opposed to the 2D ultrasound.
Polycystic Ovary Syndrome (PCOS) is fairly common among women in reproductive age; 15% of the women suffer it and many have not yet been diagnosed. PCOS is the number one cause of ovulation problems in women and therefore, subfertility. It consists of a set of signs and symptoms that affect the normal development of women. It is diagnosed through the analysis of the medical history, physical exam, ultrasounds and laboratory exams. The current criteria for the PCOS diagnosis include:
  • Signs of excess androgen (male hormones) such as hirsutism (excess hair growth in women) or blood analysis that show elevated androgen levels.
  • Irregular or absent periods
  • Polycystic Ovaries (more than 12 follicles in one ovary or a volume size of over 12cm)
It is not necessary to have all the symptoms in order for a woman to suffer this syndrome. Other conditions that explain the above conditions should be excluded. Through a complete medical history, physical exam and blood work, the physician should have sufficient information to diagnose PCOS or determine another cause of the symptoms. How can to treat PCOS? Women with PCOS, especially, those who wish to become pregnant, should seek the care of a specialized doctor to optimize their health, prevent symptom progression and achieve their dream of parenthood. Polycystic Ovary Syndrome (PCOS) cannot be cured as such, but you can control its signs and effects; sometimes even eliminate them. It is necessary to have a proper diagnosis in order to treat it and avoid the progression of the symptoms and other complications associated to it. They should be approached from an integral point of view. This means, that not only the hormonal levels will be regulated but also it is important to influence in lifestyle, since exercise and an adequate diet will help control and decrease the symptoms. CER is leader in the research and treatment of Polycystic Ovarian Syndrome in the region and is the solution for couples who wish to have a baby. With a history of over 25 years, CER is the first reproduction center in Central America. Its specialists, as well as its current Medical Director, are taken as reference at an international level. CER has the advantage of providing all services in one place. Additionally, it has a specialized laboratory with the latest technological advances. The multidisciplinary team of CER provides comprehensive support to each couple: fertility specialists, endocrinologist, nutritionist and psychologist, to accompany a process that is not always easy. Couples should know that there is a solution to their problem. The first step is to visit a specialized center to determine, exactly where lays the difficulty. An accurate diagnosis will lead to a suitable solution for you.

Hysterosalpingography or Hysterosalpingogram: done to determine if the Fallopian tubes are free and functional. It involves applying a special dye as a contrast method; then an X-ray is done and it evaluates how the dye travels through the uterus and the fallopian tubes. It might determine if there is an obstruction and at what level.

Hysterosonogram: is very similar to the Hysterosalpingogram, with the difference that an ultrasound is used together with the inyection of saline solution into the uterine cavity, to evaluate its shape and making sure it is mass-free.

These are minor surgeries, in which a small camera is used to visualize the female reproductive organs and their surroundings and they can be done as diagnostic or therapeutic purposes.

When uterine fibroids or myomas (masses) are observed, or endometriosis and other conditions that may interfere with a pregnancy are suspected, the doctor may suggest performing one of these surgeries: Hysteroscopy or Laparoscopy.

Endocrinology is the medical science dedicated to hormonal function, which is closely related to sexual and reproductive health of human beings. It is a strategic move for CER to have a team of endocrinologists and reproductive endocrinologists who seek to develop a comprehensive medicine. Hormonal balance is an essential part for the proper reproductive functioning and a good life quality. We have an on-site laboratory where we study a wide variety of hormones in real time which allow us an efficient management of the different pathologies.   

There are many reasons why a woman may be subfertile:

The physical examination is similar to a regular gynecology exam. Usually, the ovaries and the uterus are examined by ultrasound, during the first days (2-5) of the cycle. Blood analysis is also done to evaluate the hormone function.

The diagnosis of subfertility can take up to several months; therefore, do not be discouraged if you do not get a quick answer. Consider the possibility that with the current tests available a determined diagnostic cannot be reached; however, treatments to begin seeking a pregnancy can be started.
