LASER ASSISTED HATCHING IN IVF - Dr Prashant Joshi IVF Specialist Doctor /Fertility Specialist at Jayanagar Bangalore

Laser assisted hatching (LAH) is a procedure that is sometimes used in assisted reproductive technology (ART) to help improve the chances of success during in vitro fertilization (IVF). During IVF, fertilization occurs outside the body in a laboratory dish. After fertilization, the fertilized egg (embryo) is usually allowed to grow for a few days until it reaches a certain stage of development. At this point, the embryo is transferred to the woman's uterus where it can hopefully implant and grow into a healthy pregnancy. One of the challenges with IVF is that sometimes the outer shell of the embryo (called the zona pellucida) can be too thick or tough, making it difficult for the embryo to "hatch" or break out of the shell and implant in the uterus. This can reduce the chances of a successful pregnancy. LAH is a technique that can help with this problem by using a laser to create a small opening in the zona pellucida, which allows the embryo to more easily break out and implant. The LAH procedure is usually performed on day three or day five of embryo development. The embryo is first placed under a microscope and then a laser is used to make a small hole in the zona pellucida. The size and location of the hole can be carefully controlled by the embryologist, and the procedure typically takes only a few seconds to perform. There is some evidence to suggest that LAH may improve the chances of success during IVF, especially in certain cases such as older women or women with a history of failed IVF cycles. However, the procedure is not without risks. There is a small risk that the laser could damage the embryo during the procedure, and some studies have suggested that LAH may increase the risk of multiple pregnancies (twins, triplets, etc.). Overall, the decision to use LAH should be carefully considered by both the patient and the treating physician. While it may be helpful in certain cases, it is not a guarantee of success and should not be used in all IVF cycles. As with any medical procedure, it is important to fully understand the risks and benefits before making a decision.

Premature ejaculation and infertility

Premature ejaculation and infertility are two distinct medical conditions that can affect men. Premature ejaculation is a common sexual dysfunction in which a man ejaculates earlier than desired during sexual intercourse, often leading to dissatisfaction for both partners. Infertility, on the other hand, is the inability to conceive a child after a year of regular, unprotected sexual intercourse. While premature ejaculation and infertility are not directly related, there are some potential ways in which premature ejaculation can impact fertility. For example, if a man ejaculates before or immediately after penetration, there may be a reduced chance for the sperm to reach the egg and fertilize it. Additionally, premature ejaculation may lead to decreased sexual satisfaction and frequency, which can reduce the chances of conception. It's important to note, however, that premature ejaculation itself does not cause infertility. Many men with premature ejaculation are still able to co...

REASONS FOR IUI FAILURE - Dr Prashant Joshi IVF Specialist Doctor /Fertility Specialist at Jayanagar Bangalore

Intrauterine insemination (IUI) is a commonly used fertility treatment where sperm is placed directly into the uterus during the ovulation period to increase the chances of fertilization. However, despite being a popular option for couples struggling with infertility, IUI does not always result in a successful pregnancy. In this blog post, we will discuss some of the reasons why IUI may fail. Ovulation Issues: In order for IUI to be successful, it is important for the woman to ovulate regularly. If the woman is not ovulating at the right time or not ovulating at all, IUI will not be able to increase the chances of conception. Male Factor Infertility: IUI is often used in cases where the male partner has a low sperm count or other sperm-related issues. However, if the sperm quality is extremely poor, IUI may not be successful in achieving fertilization. Age-related Infertility: As women age, their fertility declines. This means that the chances of conception decrease with each passin...
