Definitions

  • Semen is comprised of sperm suspended in a fluid phase called seminal plasma. Semen analysis is the major step to determine the fertility status of a male patient or a sperm donor and involves counting spermatozoa with a microscope and examining their motility and morphology. Semen analyses are usually performed on ejaculates collected in a condom during coitus or by masturbation into a tube, bottle, or onto a plate. Freshly ejaculated human semen is a heterogeneous mixture consisting principally of fluids from prostate (approximately 20-30%), epididymis (approximately 10-15%), as well as the seminal vesicles (approximately 60-75%).
  • the epididymal fraction contains the sperm.
  • the seminal vesicles secrete a fluid that forms a soft coagulum in which spermatozoa are entrapped. Following ejaculation this clot undergoes liquefaction over a time course of approximately 20 minutes at approximately room temperature by the action of PSA (P30), a proteolytic enzyme originating in the prostate gland. Collection and donation of semen is achieved by a variety of methods, each of which may have some drawbacks. Semen collection by masturbation using a condom is considered by some donors to be unesthetic or difficult. In other instances coitus with a partner might not be an option for semen collection.
  • the initial portion of the ejaculate contains the sperm rich fraction originating in the epididymis along with secretions from Cowper's gland and prostate, followed by a mixture of prostatic and seminal vesicle secretions and finally the ejaculation wave culminates with the seminal vesicular coagulum.

  • the fertility potential of a human male can be analyzed by examining a semen sample. Semen normally contains sperm from the epididymides as well as seminal plasma contributed by the male accessory sex glands including Cowper's, prostate and seminal vesicle. Semen analyses are essential for evaluation of male infertility, effectiveness of male contraceptives, successful vasectomy or a vas reanastomosis (vasovasostomy).
  • Semen samples are also required from donors or the male partner for in vitro fertilization (IVF), intra-cytoplasmic sperm injection (ICSI), intrauterine insemination (IUI), other artificial insemination (Al) procedures or as may be required in forensic case work from suspects or donors.
  • Semen samples are usually obtained by manual masturbation, coitus interruption or by coitus with a condom. However, collecting semen in a condom by coitus may not be an option for certain persons. Furthermore, collection of semen in a condom by coitus or by masturbation results in loss of semen in the condom as well as on the skin of the penis.
  • masturbation into a test tube or in a bottle may also lead to the loss of the sperm concentrated in the initial semen fractions and result in incomplete semen evaluations.
  • Collection of semen samples by condom with transfer to a test tube through a standard funnel also involves multiple transfer related steps and has the likely potential for sample loss and inaccurate semen analysis. Loss of initial fractions may significantly affect semen analysis values, particularly sperm count and motility of a semen sample. Therefore, it is very important to recover the entire ejaculate, specially the sperm rich initial epididymal fluid fractions for sample evaluation despite the manner of collection. Unfortunately, however, no single device is available that prevents loss of semen samples during sample collection and thus optimizes semen collection and subsequent testing.
  • Some of the embodiments of the present invention provide, among other things, a semen collection device and related method particularly useful for samples collected by masturbation (or other stimulation).

Abstract

L'invention concerne un procédé et un dispositif permettant de récupérer le sperme complètement éjaculé afin d'empêcher la perte de fractions épididymales riches en sperme initial, d'éviter l'utilisation d'un condom pour la masturbation, de supprimer les transferts multi-étapes de sperme suite à une éjaculation qui sont des inconvénients communs aux procédés courants, et de fournir un seul dispositif comprenant une chambre de collecte de sperme qui s'adapte sur un gland de pénis. Ledit dispositif comprend un réservoir de stockage et de collecte, un couvercle facultatif et un support vertical placé dans module formé d'une seule pièce dans une boîte stérile. Le dispositif et le procédé sont mis en oeuvre dans de multiples utilisations dans une variété de contextes comprenant notamment le diagnostic de l'infertilité, le don de sperme, les cliniques de fécondation in vitro (IVF)/ d'injection de sperme intra-cytoplasmique (ICSI), les hospitaux, les laboratoires judiciaires et les laboratoires de recherche, et peuvent être inclus dans des kits destinés à des dispositifs d'essai de sperme en vente libre.
