The NHS recommends that, after trying and failing to get pregnant for a year, you should see your doctor; if you are over 35, you should go after six months. Help is out there, if you want it, and takes many forms. West stresses the importance of investigating both the women and the men, "even if they have previously had a healthy sperm analysis because situations and lifestyles can change". There is also the alternative therapy route: acupuncture, hypnotherapy, reflexology, meditation. Or, if all else fails, you could, like me, go for in-vitro fertilisation (IVF).
Ovarian stem cells: it is thought that women have a finite number of follicles from the very beginning. Nevertheless, scientists have found these stem cells, which may generate new oocytes in postnatal conditions.[67] Apparently there are only 0.014% of them (this could be an explanation of why they were not discovered until now).[citation needed] There is still some controversy about their existence, but if the discoveries are true, this could be a new treatment for infertility.

Artificial insemination, including intracervical insemination and intrauterine insemination of semen. It requires that a woman ovulates, but is a relatively simple procedure, and can be used in the home for self-insemination without medical practitioner assistance.[171] The beneficiaries of artificial insemination are women who desire to give birth to their own child who may be single, women who are in a lesbian relationship or women who are in a heterosexual relationship but with a male partner who is infertile or who has a physical impairment which prevents full intercourse from taking place.

We know this is a touchy subject, but unfortunately, there’s no way around it. Science says that age does play a role in fertility. This 2018 study correlated age as a statistically significant factor in secondary infertility compared to primary infertility. In the study, the average age of couples was higher among those experiencing secondary infertility.

Theoretically, IVF could be performed by collecting the contents from a woman's fallopian tubes or uterus after natural ovulation, mixing it with sperm, and reinserting the fertilised ova into the uterus. However, without additional techniques, the chances of pregnancy would be extremely small. The additional techniques that are routinely used in IVF include ovarian hyperstimulation to generate multiple eggs, ultrasound-guided transvaginal oocyte retrieval directly from the ovaries, co-incubation of eggs and sperm, as well as culture and selection of resultant embryos before embryo transfer into a uterus.
Obesity: The obesity epidemic has recently become is a serious issue, particularly in industrialized nations. The rising number of obese individuals may be due in part to an energy-rich diet as well as insufficient physical exercise.  In addition to other potential health risks, obesity can have a significant impact on male and female fertility. BMI (body mass index) may be a significant factor in fertility, as an increase in BMI in the male by as little as three units can be associated with infertility. Several studies have demonstrated that an increase in BMI is correlated with a decrease in sperm concentration, a decrease in motility and an increase DNA damage in sperm. A relationship also exists between obesity and erectile dysfunction (ED). ED may be the consequence of the conversion of androgens to estradiol. The enzyme aromatase is responsible for this conversion, and is found primarily in adipose tissue. As the amount of adipose tissue increases, there is more aromatase available to convert androgens, and serum estradiol levels increase. Other hormones including inhibin B and leptin, may also be affected by obesity. Inhibin B levels have been reported to decrease with increasing weight, which results in decreased Sertoli cells and sperm production. Leptin is a hormone associated with numerous effects including appetite control, inflammation, and decreased insulin secretion, according to many studies. Obese women have a higher rate of recurrent, early miscarriage compared to non-obese women.
Embryos are transferred to the uterus. Embryos that have developed from the fertilization process will be placed in the uterus, normally 3 to 5 days after retrieval, so that they can embed. If this process is successful, pregnancy will occur and IVF is considered a success. If it’s not, you may use a frozen embryo that you have saved from a previous round of IVF to try again.
IVF is complicated and, while we wish we could say that it's possible to absorb all the details during the 5 - 30 minute visits with your doctor, that's really not the case. This comprehensive guide to IVF boils down every major issue you'll encounter -- a high level overview of the IVF process, a deeper dive into the IVF process, IVF success rates and how they differ depending on diagnosis and age, the medication protocols that can be used during IVF, the choice of inseminating eggs either using ICSI fertilization or conventional insemination, the pros and cons of growing embryos to Day 3 cleavage stage or Day 5 blastocyst stage, the decisions around genetic screening of embryos, deciding which embryo to transfer, deciding how many embryos to transfer at once, the ways the IVF laboratory can impact your odds of success and the things you need to know up front to avoid going to the wrong lab for you, the risks of IVF, and the costs of IVF. We're always sure to provide details about how data might be different depending on different unique types of patients -- because in the world of fertility, it's really not one-size-fits-all. We truly believe this guide is the foundation every fertility patient should start with when they're navigating the world of treatments.
This chart is US national average data on success rates per IVF cycle by female age for 2014. The dark blue line (triangles) shows pregnancy rates per cycle by age. The orange line (circles) shows live birth rates per cycle by age. The rate of singleton live births per cycle is shown by the light blue line. The difference between "pregnancy" rate and "live birth" rate is due to miscarriages.
