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. -

The rationale medical terms in this manner is at variance with their scientific behind the use of artificial insemination is to increase the gamete meaning, where they denote different species or organisms (as in, density near the site of fertilization.1 The effectiveness of artificial e.g., homologous and heterologous tissue grafts). insemination has been clearly established in specific subsets of In the latter half of the 20th century, the terms artificial infertile patients such as those with idiopathic infertility, infertility insemination, donor (AID) and artificial insemination, husband related to a cervical factor, or a mild male factor infertility (AIH) found common use. However, the widespread use of the (Table 36-1).2,3 An accepted advantage of artificial insemination acronym AIDS for acquired immunodeficiency syndrome resulted is that it is generally less expensive and invasive than other in the replacement of AID with therapeutic donor insemination assisted reproductive technology (ART) procedures.4 (TDI). An analogous alternative term for AIH has not evolved, This chapter provides a comprehensive description of probably in part because of the increasingly common situation indications for artificial insemination, issues to consider before where the woman’s partner is not her legal husband. -

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. -
Sexual Reproduction

It is found in almost all the animals, plants and other life forms including fungi, bacteria and protists. A bi-parental process. Male and female gametes are formed. Germ cells act as reproductive units. Fertilization of male and female gametes occurs in order to obtain the Zygote. During meiosis, haploid gametes are produced from diploid germ cells. Produces their offspring less rapidly. Prominent male and female reproductive organs are required. Events in sexual reproduction Pre-fertilization events Fertilization Post-fertilization events Pre-fertilization events Gametogenesis Spermatogenesis Oogenesis . In most of the organisms male gamete is motile & the female gamete is stationary. In aquatic plants gamete transfer takes place through water. Male gametes are produced in very large number because a large number of male Gamete Transfer Gamete gametes are lost during transport. Fertilization . It is complete permanent fusion of two gametes from different parents or from the same parent. It results in the formation of a single celled, diploid zygote. It is of two types: External fertilization Internal fertilization Post fertilization events Zygote . Zygote is the vital link that ensures continuity -
