Sterility is the physiological inability to effect sexual reproduction in a living thing, members of whose kind have been produced sexually. Sterility has a wide range of causes. It may be an inherited trait, as in the mule; or it may be acquired from the environment, for example through physical injury or disease, or by exposure to radiation.
Sterility can be caused by different closely related species breeding and producing offspring, these animals are usually sterile due to different numbers of chromosomes from the two parents, causing an imbalance in the resulting offspring making it viable but not fertile, this is the case with the Mule. Sterility can also be caused by chromosomal differences within the patient, these individuals tend to be known as a genetic mosaics. Loss of part of a chromosome can also cause sterility due to nondisjunction. Sterility can also be caused by selective breeding, where the trait you are selecting for is closely linked to genes involved in sex determination or fertility, for example goats breed to be polled (hornless), this results in a high number of intersex individuals among the offspring, which are typically sterile.XX male syndrome is another cause of sterility, this is where the sexual determining factor on the Y chromosome (SRY) is transferred to the X chromosome due to an unequal crossing over, this gene indicated what gender the individual should be and causes the development of testes, causing the individual to be phenotypically male but genotypically female, the resulting individual is (information needed).
a series of videos on wound management. Everything from cleaning, debridement, suturing, stapling, medical glue, etc. In this specific video we talk and show you how to properly put on sterile gloves.
In this Video Lecture, Professor Fink describes the Anatomy of both the external genitalia and internal genitalia of the Male Reproductive System. Professor Fink also explains the action of the 2 Gonadotropic Hormones, Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH) on the Testes. Reference is made to the corpus spongiosum, corpora Cavernosa, seminiferous tubes, epididymis, vas deferens, seminal vesicles, prostate gland, urethral canal, and Cowper's (Bulbourethral) Glands. The difference between "puberty" and "adolescence" as well as impotence and infertility (sterility) are presented. Professor Fink also describes a circumcision, vasectomy, benign prostatic hypertrophy, prostate cancer, coitus, penile erection, vasocongestion, semen, ejaculation, and orgasm. Check-out...

Dr. Csaba Pribenszky from Vitrolife is one of the inventors of the Primo Vision System, a time-lapse solution that fully supports physiology. In this presentation he talks about the advantages of using time-lapse in IVF, and specifically about the use of Vitrolife´s time-lapse system Primo Vision. This presentation was held in the Vitrolife booth during ESHRE (European Society of Human Reproduction and Embryology) 2013 in London.

Study of physiological parameters in hybrids and varieties of pigeonpea under different production technology Ms Dipali Purushottam Thakare PhD Research Scholar Grain Legumes ICRISAT Date: 30 October 2014 Time: 1400 – 1500 h Pigeonpea is the second most important grain legume in rainfed ecosystem of India farming community. The area under pigeonpea cultivation increased significantly in last six decades but the productivity remains low (700 ± 50 kg/ha). There may be various factors responsible for the low productivity but the lack of high yielding cultivars has been identified as the major factor underlying this bottleneck. Grain yield of a plant is a complex character and has several contributory components whose multiplicative interactions yield heterosis is almost always attri...
In this video I discuss the basic physiology of the menstrual cycle and the mechanism behind the most common causes of amenorrhea like pregnancy, PCOS, premature ovarian failure, Asherman syndrome, stress, prolactinoma, hypothyroidism, Turner syndrome, Kallmann syndrome and others. I targeted this presentation toward fellow medical students, nursing students, health care professionals, and curious laymen. In part 2, I discuss the diagnostic approach to patients with amenorrhea. I hope you find this helpful.

Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including: The production of exact copies of plants that produce particularly good flowers, fruits, or have other desirable tr...
