Similarly, there is no need for testing tubal patency for couples who will require IVF or ICSI procedure. It occurs when a woman either doesn’t ovulate regularly or doesn’t ovulate at all.

Some women have bilateral tubal occlusion, which is when both tubes are blocked. A doctor injects sperm directly into the egg in a dish and then places it into your uterus. Spermatogonia and Sertoli cells lie on the basement membrane of the seminiferous tubules. Hysteroscopy can also be combined with laparoscopy when necessary.

Therefore, data estimating the prevalence of infertility cited by various sources differs significantly.[8] A couple that tries unsuccessfully to have a child after a certain period of time (often a short period, but definitions vary) is sometimes said to be subfertile, meaning less fertile than a typical couple. There are also a number of sperm production problems that can contribute to infertility, including: Scrotal varicose veins (varicoceles)  Scrotal varicose veins (varicoceles) are swollen veins causing your testicles to get hotter and affect the production of sperm  These are treated with surgery  Testicular injury   Serious trauma to the testicles such as becoming twisted (torsion) can affect sperm production  Damage from playing sports or an accident can rupture the vessels that supply blood to the testicles  Previous injuries can’t be treated, but an ART treatment may help you to conceive Undescended testicles  In the uterus, baby boys’ testicles form in their abdomen and descend into their scrotum shortly before birth  Some men’s testicles don’t descend before they are born (cryptorchidism), although in these cases they usually drop in the first six months after birth  If left untreated, undescended testicles can affect fertility Testicular cancer  This happens when a malignant tumour in the testicle destroys testicular tissue  If undetected, testicular cancer can spread to other parts of the body  This is treated either by surgery, medication, radiotherapy or chemotherapy  However, cancer therapy can also damage sperm production  Genetic defects  Sometimes, genetic information on the Y chromosome (which is only present in men) is deleted (micro-deletions),6 which can reduce the production of sperm  Depending on where the micro-deletion is on the chromosome, this may be treated by surgically extracting sperm from part of your reproductive tract  However, some couples may need to consider using a donor sperm to conceive Mumps Contracting mumps (or mumps-related orchitis) after puberty may damage the sperm-producing cells in your testicles,  causing infertility or subfertility7 Usually, only one testicle is affected and if you have one functioning testicle you may not need treatment  However, some couples may need to use a sperm donor in order to conceive Anti-sperm antibodies  Anti-sperm antibodies are large proteins in your blood that are hostile to sperm  They can cause sperm to clump together and prevent them from swimming, or they may mistake sperm cells for an infection and try to destroy them  This can be treated using an ART treatment   Lifestyle   Sperm production can be affected by a range of lifestyle factors, including smoking, drinking, drugs, stress, overweight and unhealthy food Environmental factors can also affect your sperm quality, including overheating of your testicles, some sexual lubricants, the chemicals involved in certain manufacturing, painting or printing jobs   These factors are treated by making lifestyle changes, such as wearing loose clothing to avoid overheating Hormonal problems  Hormonal problems are rarely the cause of male infertility problems  However, some men have a natural deficiency in follicle-stimulating hormone (FSH) and luteinising hormone (LH), which prevents the testicles from producing testosterone or developing healthy sperm  Hormonal problems can usually be treated with medication Obstruction problems Blocked sperm ducts  Occasionally, male sperm ducts (epididymis and vas deferens) can become blocked, meaning that your semen doesn’t contain any sperm  This can be treated with surgery, or sperm may be surgically extracted from part of your reproductive tract  Vasectomy  Some men have had a previous vasectomy to stop them being able to conceive  This can sometimes be reversed using surgery  The procedure’s success depends on how long ago your vasectomy was performed  Previous infections  Infections can cause scarring or adhesions (organs sticking together) in your sperm ducts  This can usually be treated with surgery  Does age affect male fertility?

Clomiphene citrate and/or Metformin. - folliculometry via TVUSS should be done to avoid multiple pregnancies and risk of OHSS. - Not for more than 6 months. Outside pregnancy and lactation, women with high levels of prolactin may have irregular ovulation cycles and fertility problems. Fimbrioplasty for fimbria agglutination or phimosis without destruction of the cilial epithelium is equally successful.

Signs of infertility include irregular, excessively heavy, or absent periods as well as sudden weight gain, painful sex, or vaginal infections. Twelve months is the lower reference limit for Time to Pregnancy (TTP) by the World Health Organization.[7] a woman over 35 has not conceived after six months of contraceptive-free sexual intercourse. When the eggs are mature, your doctor collects them with a device called a vaginal ultrasound probe. Women who have a body weight 10% to 15% below normal may have reduced fertility. Sperm density Normal sperm density is greater than 20 million sperm/mL. One of the best known is the HFEA – The UK's regulator for fertility treatment and embryo research. Uterine fibroids Fibroids are noncancerous growths in the uterus. One of the best known is the HFEA – The UK's regulator for fertility treatment and embryo research. 42 Urinary luteinizing hormone kits indicate the midcycle luteinizing hormone surge that precedes ovulation by one to two days. Distribution of Spermatogenesis in the Testicles of Azoospermic Men: The Presence of Spermatids in the Testes of Men with Germinal Failure. (PDF, 295 KB) Human Reproduction, 1997. Many uterine and tubal abnormalities detected by the HSG can be surgically corrected. In order to conceive, your sperm must be:  Highly concentrated — normally, there should be at least 15 million sperm in every ml of semen5  Moving well (motile) — a lashing tail helps your sperm to swim to your partner’s egg  Normally shaped — healthy sperm should be shaped like a streamlined tadpole  You may find that your semen contains a very low number of sperm (oligozoospermia), or no sperm at all (azoospermia). Usually no more than 1 – 2 embryos are transferred, and therefore additional embryos can be frozen, or cryopreserved, for future use; 3) embryo donation – a process where a fully developed embryo from another person in combination w/donor sperm, or couple who underwent IVF, are donated to another woman, the future intended mother, for transfer into her uterus; and 4) gestational surrogacy – a process where another woman will undergo an embryo transfer and carry the pregnancy for another person.
