This method is used almost exclusively in AI centers for practical reasons and because it produces physiological semen samples.

While the above would suggest more precise deposition of the semen in the uterine horn ipsilateral to the side of the impending ovulation would result in improved CRs, the AI technician would require a higher level of skill to accurately determine the side of the impending ovulation by rectal palpation and to avoid any risk of prematurely bursting the dominant follicle. Dilator therapy is easier than you think. It's important to note that vaginal dilators are not sex toys or vibrators, but medical devices used to help women overcome painful vaginal penetration and sexual problems. How to use dilation therapy depends on each person, but generally, the following steps help ensure success. Semiautomatic filling equipment, such as the SFS 133, ( Fig. 27 ) fills preprinted straws using a vacuum pump and seals them with glass or metal sealing balls. Not coming out? Get to urgent care or an emergency room right away. Keep your genital area as still as possible to prevent any sudden or abrupt movement that could injure your urethra.

Thawing of frozen semen should be at maximum speed. Rapid thawing decreases the harmful effects of water recrystallisation and rehydration, thus preventing damage to sperm membrane and cytoplasm. The critical temperature zone for ice crystals to form is between ~ −50°C and ~0°C. Rapid progression though this temperature zone means that the semen switches from glassy to a liquid state and ice crystals have insufficient time to form. Numerous studies have been conducted to determine the thawing rate that gives the highest post-thaw percentage of viable sperm (Correa et al., Reference Correa, Rodriguez, Patterson and Zavos1996). In some studies thawing temperatures as high as 60°C to 80°C for 6 to 7 s have given improved post-thaw sperm motility and viability (Senger, Reference Senger1980; Lyashenko, Reference Lyashenko2015). However, the duration of exposure to such high temperature is critically important and there appears to be very little scope for error unlike the situation when straws are thawed at lower temperatures.

Gaining sexual superiority over other women was a recurring theme, and a strong motivator for using vaginal- or sex-enhancing products among some participants. Sexual superiority could be obtained through the use of vaginal products to make the vagina tighter, hotter and/or drier than other girls. Notably the motivation was often to be the preferred partner, not necessarily the only one: After collecting a suitable sample, the stimulation is stopped and the rectal probe is removed. The semen sample is then taken to the lab for evaluation and processing.

The notion of preparedness was considered independently of intercourse, with an emphasis on being ready for sex with your partner regardless of whether or not intercourse actually occurred. This may be because young women are unable to predict when sex will take place. One participant highlighted always being ready for sex in the FGD by saying: Within a column, values without a common superscript letter (x, y) differ ( P<0.05). Within a row, values without a common superscript letter (a, b) differ ( P<0.05).

Example: in a 9.5 ml ejaculate with the following characteristics: 75% progressively motile sperm; 80% morphologically normal sperm; concentration of 620 million spermatozoa/ml Bulls should be sexually rested for 1 - 2 days before electroejaculation to allow sperm to accumulate in the ampullae. With good equipment and proper technique, only about 2% of normal fertile bulls fail to emit semen by electroejaculation. Electroejaculation without anesthesia is considered to be painful to bulls and is controversial in some countries. Vocalization during electroejaculation, an elevation of circulating adrenal progesterone and cortisol after electroejaculation are evidence of pain. Therefore, the procedure must only be done by personnel with proper training and always in the gentlest way possible. Evaluation of Semen Quality
