Treatment Options
Your team is committed to creating a treatment plan built for your unique needs—whether that’s IVF, IUI, or one of our many other service options.
In Vitro Fertilization (IVF) involves retrieving eggs from the ovaries and fertilizing them in a lab with sperm from a partner or donor to create embryos. An embryo is then placed back into a uterus with the goal of pregnancy.
Intrauterine Insemination (IUI) is a treatment that involves inserting sperm directly into the uterus during the most fertile time in your cycle. This increases the chance that the sperm will fertilize the egg and result in pregnancy.
Miscarriage can be extremely emotionally challenging. Most people who experience pregnancy loss go on to have normal, healthy pregnancies. If you’ve experienced two or more miscarriages, treatment for recurrent pregnancy loss could help.
Genetic testing with Celenova Fertility involves running tests on each embryo before implantation. This helps to increase the chances of a healthy pregnancy by reducing the risk of implanting an embryo with genetic abnormalities. This process can also decrease chances of miscarriage, which is often associated with chromosomal issues in the embryo.
Male infertility is an extremely common contributing factor to a couple’s inability to conceive. Infertility is a complex issue, and it’s just as important to test the male partner as it is to test the female partner. The first step is a semen analysis to determine sperm quality and quantity. From there, we can determine if there are further underlying issues and how to address them.
Egg freezing is a process in which eggs are retrieved from the ovaries and preserved for future use. You may choose to delay parenthood for any number of reasons, whether it’s professional goals, family medical history, or simply a desire to have a child later in life. Egg freezing can also be an incredible resource for those undergoing medical treatments that can impact fertility.
You deserve a medical team that understands your unique fertility needs. We tailor each treatment plan to the specific needs of the patient, whether we’re working with a same-sex couple, transgender patient, or someone who desires single parenthood. There are so many options for building your family your own way.
Using a donor egg is an option for anyone struggling with a diminished egg supply. This process involves fertilizing the donor egg via IVF then placing it into the uterus of the person carrying the pregnancy. Deciding on egg donation can be an emotionally complex step, and we are here to support you throughout your journey.
In surrogacy a fertilized embryo is implanted into a gestational carrier’s (also known as a surrogate) uterus to carry the pregnancy. The gestational carrier usually isn’t genetically related to the child. Surrogacy can be a path to parenthood for male couples, transgender people, and patients who are unable to carry a pregnancy.
