Artificial Insemination Steps Sows should initially be inseminated 12 or 24 hours after standing in estrus, and then inseminated every 12-24 hours after for as long as they stand in estrus. Most producers inseminate gilts when they are found in standing heat, and every 12 hours thereafter for as long as they stand. Semen needs to be in the female reproductive tract 6 to 8 hours prior to ovulation. After you have determined that the female is in estrus or heat, use the following steps to aid in artificially servicing the animal. Sperm cells survive approximately 24 hours when placed in the reproductive tract of the female. Thus, it is always better to inseminate early in the estrus phase, rather than late. 1. Normal surroundings • A boar in the alleyway may make insemination easier, females often exhibit strong standing reflex in the presence of boars (due to pheromones). 2. Vulvar hygiene • Clean the vulva and surrounding area with a single-use paper towel prior to insemination. 3. Preparing the catheters • A catheter is used to move semen from a bottle or tube into the sow’s reproductive tract. • Keep catheter in a sealed plastic bag until required for use to prevent it from getting dirty before use. 4. Stimulating the sow • The female should be stimulated to stand in a way that “mimics the actions of a boar.” This can be achieved by: • Apply pressure on its back • Stimulate the flanks. • Massage udder 5. Inserting the catheter • Keep the following steps in mind while inserting the catheter: 1. Insert slowly 2. Direct tip upward 3. Rotate counterclockwise 4. The catheter is locked into cervix when resistance is felt. 6. Depositing semen • To ensure that proper artificial insemination occurs, be aware of the following procedures: • Do not open the semen bottle or tube until after the catheter has been inserted. • The goal is to get the semen in the sow’s tract without backwash. • Allow the semen to run under gravity or let the sow draw the semen in by uterine contractions. • It will take 5 to10 minutes to complete insemination..

INTRAUTERINE INSEMINATION of HUSBAND's SEMEN Departments
INTRAUTERINE INSEMINATION OF HUSBAND'S SEMEN B. N. BARWIN Departments of Physiology and Midwifery & Gynaecology, The Queen's University of Belfast, Northern Ireland (Received 11 th January 1973) Summary. Fifty patients with primary infertility were treated by intra- uterine insemination of the husband's semen which had been stored. Thirty patients had sperm counts of greater than 20 \m=x\106/ml with 50% motility and twenty patients had oligospermia (<20 \m=x\106/ml). The technique of storage of semen is reported and the intrauterine method described. The r\l=o^\leof the buffer solution is discussed in over- coming the complications of intrauterine insemination. A success rate of 70% is reported in the normospermic group and 55% in the oligo- spermic group over nine cycles of intrauterine insemination of husband's semen. INTRODUCTION One of the main problems confronting the gynaecologist in the investigation of infertility is the consistent finding of immotile spermatozoa, spermatozoa of low motility and low sperm count in the cervical mucus or semen (Scott, 1968). There was considerable controversy among earlier workers in the field that the sperm count was substandard if it fell below 60 106/ml but MacLeod (1962) has carried out considerable research in this field and it is now generally accepted that true oligospermia is represented by counts of less than 20 IO6/ ml provided the motility is good. SUBJECTS AND METHODS Selection of cases Fifty couples with primary infertility of between 3 and 14 years' duration were selected. The age distribution was between 24 and 41 years. In all cases, the wives had been subjected to a full clinical investigation.

If one wants to deal with the casuistry of artificial insemination (AI). it is necessary to bring forth certain theological and anthropological presuppositions on the basis of which individual instances of AI are judged. Section I: Theological and Anthropological Presuppositions. I. The fundamental starting point consists of certain foundational affirmations regarding the origin of the human person. 1.1 The mystery of the origin of every human person has its roots in the very mystery of God. The origin of a human person. as a matter of fact. is not some kind of chance biological happening. but is the result of a creative act. that is. a deliberate and free choice on the part of God to do something He is no way obliged to do.

Artificial Insemination Instructions
Artificial Insemination Instructions There are basically 3 ways of doing an at-home insemination: 1. The so-called Turkey Baster Method, though it is smarter to use a needle-less syringe than a turkey baster. 2. Insemination using a Cervical Cap, Diaphragm or Soft Cup. 3. Using a Cervical Cap with Access Tube, such as the Oligiosperma Cup (needs to be purchased through a doctor). This is a cervical cap with a tube for adding sperm after the cup is in place. TURKEY BASTER METHOD (NEEDLELESS SYRINGE) Supplies needed: • Needle-less Syringe • Collection Cup • Saline without additives or preservatives (Optional) • Tube to attach to syringe (Optional) The syringe should have a plunger, not a bulb end (not the mini turkey baster!). All syringes work pretty much the same way. You can attach a catheter (thin tube) to the syringe but you don't need to and it may waste more of the semen to use one. 1. Have the male ejaculate into a clean, sterile plastic collection cup (if using fresh semen). You'll probably have the best luck getting the semen out of a collection cup since you could suck a baggy or condom up into the syringe and block the opening. You can use a tiny bit of saline, without additives/preservatives, to help get as much sperm as possible into the syringe, but you don't need to worry too much about leaving a little behind. If you are using frozen sperm, you need to ask the sperm bank for directions on thawing. 2. Draw back on the syringe once with nothing but air, then push the air out again.
