Considering this is in the “assisted Fertility” section, I’m assuming you’re not wanting “have sex” or “seriously?” as an answer as the juveniles on here have put. Yes this may work for a few people but certainly not for everyone. I’m single, I’m not going out to have sex with some random to get pregnant, also the chances that will work when fertility treatments have not worked is pretty remote anyway. 1) have sex. If this doesn’t work, refer below. 2) monitored cycles. They may or may not put you onto clomid to help you ovulate. Then you get scans to see when you’re going to ovulate, I think sometimes they even give you a trigger injection to induce ovulation. Then you get busy with your partner. This can help if you’re not sure when you ovulate, can enhance natural babymaking. 3) IUI. This can also be medicated or natural. Often again they use Clomid to help you ovulate more than one egg. They take sperm, either from your partner or a donor, wash it, and then put it into your uterus when you’re about to ovulate (scans are used again), using a syringe with a long thin tube (catheter) on it to get through the cervix. This is often effective in cases of unexplained infertility. 4) IVF or In Vitro Fertilisation. There are many ways to do this, many different medication protocols, with or without ICSI (Intra Cytoplasmic Sperm Injection), with or without PGS (Preimplantation Genetic Screening), fresh or frozen embryo replacement. The basic way is they induce you to produce lots and lots of eggs (except mini IVF where quality is preferred over quantity). Then after several weeks they harvest the eggs from your ovaries (using a needle on an ultrasound wand put into your vagina) right before you’re going to ovulate, if you ovulate it’s too late, they’re gone. Then they put them into a container with sperm, either your partner’s or a donor’s, and wait for them to fertilise. Any eggs that fertilise, they continue to grow them for either three days or five days, this is standard, but may vary by one or two days. Then they can either transfer them fresh to your uterus, or freeze them for later, or even a combination of the two. You get more medications over the next few days to prepare your uterus for the embryos. 5) Freeze your eggs or ovarian tissue for later, and then use IVF, or may be able to get pregnant naturally if you’ve frozen ovarian tissue. This is fraught with difficulties. The chances of your eggs surviving freezing and thawing are much less than for embryos, plus there’s no way to know if your frozen eggs are any good until you try them. Also it’s best to freeze them in your 20’s and not many people know then what their plans are, or certainly aren’t expecting to have problems getting pregnant, unless you’re having chemotherapy of course. Also it’s expensive, as it’s most of an IVF procedure, minus the IVF and putting the embryos back, a cost most people would struggle to afford at any age, let alone when in your 20’s. You also get all the side effects of the medications.
