In 1985, he constructed the pelvi-trainer = laparo-trainer, a practical surgical model whereby colleagues could practice laparoscopic techniques. Intracytoplasmic sperm injection[edit] ICSI technique is used in case of poor semen quality, low sperm count or failed fertilization attempts during prior IVF cycles. The procedure is performed 30-34 hours after the spontaneous LH surge or 36 hours after the administration of 10,000 U of hCG (human chorionic gonadotropin). [110] The sperm is delivered into the endometrial cavity using an intrauterine insemination catheter. The farther from the scrotum, and the longer duration that the testicle resides outside the scrotum, the greater the likelihood of infertility. Once a follicle containing an egg reaches a mature size, another hormone injection called HCG is often given to mimic the natural LH surge that occurs at the time of ovulation.

In men who have the necessary reproductive organs to procreate, infertility can be caused by low sperm count due to endocrine problems, drugs, radiation, or infection. ICSI offers a high pregnancy rate and 70—80 % of eggs are fertilized through this technique.

Drugs used for both women and men[67] include clomiphene citrate, human menopausal gonadotropin (hMG), follicle-stimulating hormone (FSH), human chorionic gonadotropin (hCG), gonadotropin-releasing hormone (GnRH) analogues, aromatase inhibitors, and metformin. Temporal relationship and reliability of the clinical, hormonal, and ultrasonographic indices of ovulation in infertile women. Medical conditions Some medical conditions can affect fertility.

Less than 50% motility may significantly affect the ability for sperm to fertilize the egg without therapy; and (4) morphology, or shape – there are three parts of the sperm that are analyzed for morphology: the head, midpeice, and tail.

Ovulation disorders About one quarter of infertility cases are due to ovulation disorders. Surprisingly, the complete absence of sperm in the semen (a condition known as azoospermia), can be a good thing. The introduction in 1990 of a laparoscopic clip applier with twenty automatically advancing clips (rather than a single load clip applier that would have to be taken out, reloaded and reintroduced for each clip application) made general surgeons more comfortable with making the leap to laparoscopic cholecystectomies (gall bladder removal). Infertility may be caused by blockage of the Fallopian tube due to malformations, infections such as chlamydia or scar tissue.

Testicular Neoplasm in Father and Son. (PDF, 561 KB) The Journal of Urology, 1972. Most couples (about 84%) who have regular sexual intercourse (that is, every two to three days) and who do not use contraception get pregnant within a year. A defect in any of these sperm structures may result in infertility that will not be detected by semen analysis.[60] Antisperm antibodies cause immune infertility.[23][24] Cystic fibrosis can lead to infertility in men.

Most couples skip the invasive laparoscopic surgery and do treatments with intrauterine inseminations and then IVF if inseminations are not successful. Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery.
